Refer to Fig. 30 and 31 for more detailed power exhaust switch information. 2 SEQUENCE OF OPERATION 50TFQ004-012 Units energized and the position of the economizer damper will be determined by the supply-air temperature. Compressor no. 2 (50TFQ008-012) is locked out. When the second stage of cooling is satisfied, the compressor, RVS2, and outdoor-fan motor(s) will be deenergized. The damper position will be determined by the supply-air temperature. When the first stage of cooling is satisfied, the damper will move to fully closed position. When using continuous fan, the damper moves to minimum position. COOLING UNITS WITH ECONOMI$ER (EconoMi$er, Johnson Actuator, was produced from Unit Serial Numbers from 2009Gxxxxx to 0702Gxxxxx) (Sizes 004-007) — When the outdoor-air temperature (OAT) is above the ECON SP set point and the room thermostat calls for Stage 1 cooling, terminals G and Y1 are energized. The indoor-fan contactor (IFC), reversing valve solenoid (RVS1) and compressor contactor no. 1 (C1) are energized and indoor-fan motor, compressor no. 1 and outdoor fans start. The EconoMi$er damper modulates to minimum position. The outdoor-fan motor(s) runs continuously while unit is cooling. After the thermostat is satisfied, the damper modulates to the fully closed position when the IFM is deenergized. When the OAT is below the ECON SP setting and the room thermostat calls for Stage 1 cooling (R to G + Y1), the EconoMi$er modulates to the minimum position when the IFM is energized. The EconoMi$er provides Stage 1 of cooling by modulating the return and outdoor-air dampers to maintain a 55 F supply air set point. If the supply-air temperature (SAT) is greater than 57 F, the EconoMi$er modulates open, allowing a greater amount of outdoor air to enter the unit. If the SAT drops below 53 F, the outdoor air damper modulates closed to reduce the amount of outdoor air. When the SAT is between 53 and 57 F, the EconoMi$er maintains its position. If outdoor-air alone cannot satisfy the cooling requirements of the conditioned space, and the OAT is above the MECH CLG LOCKOUT set point, the EconoMi$er integrates free cooling with mechanical cooling. This is accomplished by the strategies below. NOTE: Compressor has a 2-minute Minimum On, Minimum Off, and Interstage delay timer. 1. If Y1 is energized, and the room thermostat calls for Y2 (2-stage thermostat), the compressor, RVS1 and OFM are energized. The EconoMi$er damper is maintained at its current position. 2. If Y1 is energized for more than 20 minutes, and Y2 is not energized (whether or not a 2-stage thermostat is used), the compressor, RVS1 and OFM are energized. The EconoMi$er damper is maintained at its current position. 3. If Y1 is energized, the compressor and RVS1 are already energized (see Step 2) and the room thermostat calls for Y2, the compressor continues to operate. 4. If compressor and RVS1 are energized and the thermostat is satisfied, the compressor, RVS1, the OFM, and IFM are deenergized and the EconoMi$er modulates closed. When the OAT is below the MECH CLG LOCKOUT set point, the compressors remain off. COOLING, UNITS WITH ECONOMI$ER (EconoMi$er, Johnson Actuator, was produced from Unit Serial Numbers from 2009Gxxxxx to 0702Gxxxxx) (Sizes 008-014) — When the outdoor-air temperature (OAT) is above the ECON SP set point and the room thermostat calls for Stage 1 cooling, terminals G and Y1 are energized. The indoor-fan contactor (IFC), reversing valve solenoid (RVS1) and compressor contactor no. 1 (C1) are energized and indoor-fan motor, compressor no. 1 and outdoor fans start. The EconoMi$er damper modulates to minimum position. The outdoor-fan motor(s) runs continuously while unit is cooling. After the thermostat is satisfied, the damper modulates to the fully closed position when the IFM is deenergized. COOLING, UNITS WITHOUT ECONOMIZER — When thermostat calls for cooling, terminals G and Y1 are energized. The indoor-fan contactor (IFC), reversing valve solenoid (RVS1) and compressor contactor no. 1 (C1) are energized and indoor-fan motor, compressor no. 1, and outdoor fans start. The outdoor-fan motor(s) run continuously while unit is cooling. On 50TFQ008-012 units, if the thermostat calls for a secondstage of cooling by energizing Y2, compressor contactor no. 2 (C2) and reversing valve solenoid (RVS2) are energized and compressor no. 2 starts. HEATING, UNITS WITHOUT ECONOMIZER (Sizes (004-007) — Set system switch at AUTO. or HEAT position. Set thermostat at desired temperature. When the thermostat calls for heat, the IFC, outdoor-fan contactor (OFC), and compressor contactor are energized. The RVS is deenergized and switches position, and the indoor fan, outdoor fan, and compressor are energized. If the thermostat calls for a second stage of heat, the heater contactor (HC) is energized and starts the electric heaters. When the space temperature approaches the heating temperature set point, heating stages cycle off. HEATING, UNITS WITHOUT ECONOMIZER (Sizes 008-012) — Upon a request for heating from the space thermostat, terminal W1 will be energized with 24 v. The IFC, outdoor-fan contactor (OFC), C1, and C2 will be energized. The reversing valves switch position and deenergize, and the indoor fan, outdoor fan, compressor no. 1, and compressor no. 2 are energized. If the space temperature continues to fall while W1 is energized, W2 will be energized with 24 v, and the heater contactor(s) (HC) will be energized, which will energize the electric heater(s). When the space thermostat is satisfied, W2 will be deenergized first, and the electric heater(s) will be deenergized. Upon a further rise in space temperature, W1 will be deenergized, and the compressors will turn off. COOLING, UNITS WITH DURABLADE ECONOMIZER — When the outdoor-air temperature is above the outdoor-air thermostat (OAT) setting and the room thermostat calls for cooling, compressor contactor no. 1 is energized to start compressor no. 1 and the outdoor-fan motor(s). RVS1 (reversing valve solenoid) is energized. The indoor-fan motor is energized and the economizer damper moves to the minimum position. Upon a further call for cooling, compressor contactor no. 2 will be energized (50TFQ008-012), starting compressor no. 2. RVS2 is energized. After the thermostat is satisfied, the damper moves to the fully closed position. When using continuous fan, the damper moves to minimum position. When the outdoor-air temperature is below the OAT setting and the thermostat calls for cooling, the economizer dampers move to the minimum position. If the supply-air temperature is above 57 F, the damper continues to open until it reaches the fully open position or until the supply-air temperature drops below 52 F. When the supply-air temperature falls to between 57 F and 52 F, the damper will remain at an intermediate open position. If the supply-air temperature falls below 52 F, the damper will modulate closed until it reaches the minimum position or until the supply-air temperature is above 52 F. When the thermostat is satisfied, the damper will move to the fully closed position. When using continuous fan, the damper moves to minimum position. If the outdoor air alone cannot satisfy the cooling requirements of the conditioned space, economizer cooling is integrated with mechanical cooling, providing second-stage cooling. Compressor no. 1 reversing valve solenoid (RVS1) and the outdoor fan will be 3 HEATING, UNITS WITH ECONOMIZER INCLUDING DURABLADE, ECONOMI$ER (Johnson) OR ECONOMI$ER2 (Sizes 008-012) — Upon a request for heating from the space thermostat, terminal W1 will be energized with 24 v. The IFC, outdoor-fan contactor (OFC), C1, and C2 will be energized. The reversing valves switch position and the indoor fan, outdoor fan, compressor no. 1, and compressor no. 2 are energized. The economizer damper blade opens to minimum position. If the space temperature continues to fall while W1 is energized, W2 will be energized with 24 v, and the heater contactor(s) (HC) will be energized, which will energize the electric heater(s). When the space thermostat is satisfied, W2 will be deenergized first, and the electric heater(s) will be deenergized. Upon a further rise in space temperature, W1 will be deenergized, and the reversing valve solenoids (RVS1 and RVS2) will be energized. DEFROST (Sizes 004-007) — As frost builds up on the outdoor coil, the coil temperature drops below 28 F. When this outdoor-coil temperature drop is sensed by the defrost thermostat (DFT) and the defrost timer is at the end of a timed period (adjustable at 30, 50, or 90 minutes), the unit operates in a defrost cycle controlled by the defrost timer and thermostat. During this cycle, the reversing valve solenoid (RVS) is energized and the outdoor fan shuts off. The electric heaters (if installed) will be energized. The unit continues to defrost until the coil temperature as measured by DFT reaches 65 F, or the duration of defrost cycle completes a 10-minute period. At the end of the defrost cycle, the electric heaters (if installed) and the reversing valve will be deenergized, and the outdoor-fan motor will be energized. The unit will now operate in the Heating mode. If the thermostat is satisfied during a defrost cycle, the unit will continue in the Defrost mode until the time or temperature constraints are satisfied. DEFROST (Sizes 008-012) — When the temperature of the outdoor coil drops below 28 F as sensed by the defrost thermostat (DFT2) and the defrost timer is at the end of a timed period (adjustable at 30, 50, or 90 minutes), reversing valve solenoids (RVS1 and RVS2) are energized and the OFC is deenergized. This switches the position of the reversing valves and shuts off the outdoor fan. The electric heaters (if installed) will be energized. The unit continues to defrost until the coil temperature as measured by DFT2 reaches 65 F, or the duration of defrost cycle completes a 10-minute period. During the Defrost mode, if circuit 1 defrosts first, RVS1 will oscillate between Heating and Cooling modes until the Defrost mode is complete. At the end of the defrost cycle, the electric heaters (if installed) will be deenergized; the reversing valves switch and the outdoor-fan motor will be energized. The unit will now operate in the Heating mode. If the space thermostat is satisfied during a defrost cycle, the unit will continue in the Defrost mode until the time or temperature constraints are satisfied. When the OAT is below the ECON SP setting and the room thermostat calls for Stage 1 cooling (R to G + Y1), the EconoMi$er modulates to the minimum position when the IFM is energized. The EconoMi$er provides Stage 1 of cooling by modulating the return and outdoor-air dampers to maintain a 55 F supply air set point. If the supply-air temperature (SAT) is greater than 57 F, the EconoMi$er modulates open, allowing a greater amount of outdoor air to enter the unit. If the SAT drops below 53 F, the outdoor air damper modulates closed to reduce the amount of outdoor air. When the SAT is between 53 and 57 F, the EconoMi$er maintains its position. If outdoor-air alone cannot satisfy the cooling requirements of the conditioned space, and the OAT is above the MECH CLG LOCKOUT set point, the EconoMi$er integrates free cooling with mechanical cooling. This is accomplished by the strategies below. NOTE: Compressors have a 2-minute Minimum On, Minimum Off, and Interstage delay timer. 1. If Y1 is energized, and the room thermostat calls for Y2 (2-stage thermostat), compressor no. 1, RVS1 and OFM are energized. The EconoMi$er damper is maintained at its current position. 2. If Y1 is energized for more than 20 minutes, and Y2 is not energized (whether or not a 2-stage thermostat is used), compressor no. 1, RVS1 and OFM are energized. The EconoMi$er damper is maintained at its current position. 3. If Y1 is energized, and compressor no. 1 is already energized (see Step 2) and the room thermostat calls for Y2, compressor no. 1 continues to operate. If Y2 remains energized for more than 20 minutes, compressor no. 2 and RVS2 are energized. NOTE: Compressor no. 2 cannot be energized unless there is a signal for Y2 from the space thermostat. 4. If compressor no. 2 is energized, and the Y2 signal from the thermostat is satisfied, compressor no. 1 and 2, RVS1, RVS2 and ODF are deenergized. Reasserting Y2 will start compressor no. 1 and (after a 20-minute interstage delay) compressor 2. 5. If compressor no. 1 is energized and the thermostat is satisfied, compressor no. 1, the OFM, RVS1 and IFM are deenergized and the EconoMi$er modulates closed. HEATING, UNITS WITH ECONOMIZER INCLUDING DURABLADE, ECONOMI$ER (Johnson) OR ECONOMI$ER2 (Sizes 004-007) — Set system switch at AUTO. or HEAT position. Set thermostat at desired temperature. When the thermostat calls for heat, the IFC, outdoor-fan contactor (OFC), and compressor contactor are energized. The economizer damper blade opens to minimum position. The RVS is deenergized and switches position, and the indoor fan, outdoor fan, and compressor are energized. If the thermostat calls for a second stage of heat, the heater contactor (HC) is energized and starts the electric heaters. When the space temperature approaches the heating temperature set point, heating stages cycle off. The reversing valve solenoid is reenergized. 4 LEGEND AHA AWG BR C CAP CB CC CH CLO CO2 COC COH COM COMMS COMP CR CTD D DAT DB DFT DM DR DX EC ECON EFC EPS EQUIP ER FC FPT FU GND GVR HC HM HPS HR HTR HV TRAN I IAQ IFC IFM IFMOVL IFR IGC LED LPS LSM — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — LTLO MCA MGV MTR NC NEC NO OAT OATC OATH OCR OFC OFM OLR P, PL QT R RVS SAT SW SW1 SW2 SW3 SW4 TB TC TDR TH TRAN VVT® Adjustable Heat Anticipator American Wire Gage Blower Relay Contactor, Compressor Capacitor Circuit Breaker Cooling Compensator Crankcase Heater Compressor Lockout Carbon Dioxide Cool Changeover Relay Heat Changeover Relay Common Communications Compressor Motor Control Relay Compressor Time Delay Diode Discharge Air Thermistor Defrost Board Defrost Thermostat Damper Motor Defrost Relay Direct Expansion Enthalpy Control Economizer Exhaust Fan Contactor Emergency Power Supply Equipment Economizer Relay Fan Contactor Freeze Protection Thermostat Fuse Ground Gas Valve Relay Heater Contactor (Electric Heater) Humidity Relay High-Pressure Switch Heater Relay Heater High-Voltage Transformer Ignitor Indoor Air Quality Indoor-Fan Contactor Indoor-Fan Motor Indoor-Fan Motor Overload Switch Indoor-Fan Relay Integrated Gas Controller Light Emitting Diode Low-Pressure/Loss-of-Charge Switch Limit Switch (Manual Reset) — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — Low Temp Cooling Lockout Minimum Circuit Amps Main Gas Valve Motor Normally Closed National Electrical Code Normally Open Outdoor-Air Thermostat Outdoor Air Thermostat (Cool) Outdoor Air Thermostat (Heat) Occupied Relay Outdoor-Fan Contactor Outdoor-Fan Motor Overload Relay Plug Quadruple Terminal Relay Reversing Valve Solenoid Supply-Air Thermostat Switch Switch, Fully Open Switch, Fully Closed Switch Minimum Vent Position Switch Maximum Vent Position Terminal Block Thermostat, Cooling Time-Delay Relay Thermostat, Heating Transformer Variable Volume/Variable Temperature Field Splice Terminal (Marked) Marked Wire Terminal (Unmarked) Terminal Block Splice Splice Marked Factory Wiring Field Control Wiring Field Power Wiring Accessory or Optional Wiring To indicate common potential only.

The standard EconoMi$er2 is shipped with a fixed dry bulb sensor. (Open 67 F — Close 52 F.) An adjustable dry bulb or enthalpy sensor can replace the fixed dry bulb. (See Note 6.) 2. CO2 sensor is optional. Field-installed accessory. See rooftop price pages for ordering data and pricing. Power for CO2 sensor should be provided by field-supplied transformer. 3. The HVAC unit is shipped with a jumper plug attached to the EconoMi$er2 harness. Remove the jumper plug and save for future use if economizer is removed. Connect the male side of plug (shown above) to the female side in HVAC unit. 4. 1S is an electronic switch that closes when powered by a 24 vac input. 5. Factory-installed 620-ohm, 1 watt, 5% resistor should be removed only when a HH57AC078 enthalpy sensor or CROASENR001A00 adjustable dry bulb is added to SR and + for differential sensing. 6. When replacing the fixed dry bulb sensor with an enthalpy or adjustable dry bulb, remove the 820-ohm resistor. 7. Compressor lockout (Open 35 F — Close 50 F). 8. See EconoMi$er2 Installation Instructions for details on locating and wiring supply air (mixed air) sensor. 9. Switch on actuator must be in run position for economizer to operate. 10. A 2-stage thermostat is recommended. 11. Before troubleshooting wiring, ensure that all the correct sensors have been installed (refer to EconoMi$er2 Installation Instructions).

EconoMi$er2 actuator and controller are shipped with the EconoMi$er2 — not with power exhaust. 3. Connections from End Switch plug to the EconoMi$er2 controller are made by installer. 4. If a single power source is to be used, size wire to include power exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered through the unit. Determine the new MCA including the power exhaust using the following formula: MCA New = MCA unit only + MCA of Power Exhaust For example, using a 48HJD006---5 unit with MCA = 28.9 and MOCP = 35, with CRPWREXH030A00 power exhaust. MCA New = 28.9 amps + 1.6 amps = 30.5 amps If the new MCA does not go over the MOCP published, then MOCP would not change. The MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is OK. If “MCA New” is larger than the published MOCP, raise the MOCP to the next larger size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.
