Q7100A,C,D Thermostat Subbases INSTALLATION INSTRUCTIONS APPLICATION The Q7100 Thermostat Subbases provide electronic control of commercial 24 Vac single or multistage heat pump or conventional heating and cooling systems. Select models have terminals for light emitting diodes LEDs, remote temperature sensors and remote setback timer. The LED models have up to two field configurable LEDs and up to two factory assigned LEDs. Refer to Table 1. All Q7100 Thermostat Subbases require a common wire to the supply power. 3. Installer must be a trained, experienced service technician. 4. After completing installation, use these instructions to check out the product operation. CAUTION Disconnect power supply to prevent electrical shock or equipment damage. Location Subbase without Remote-Mounted Temperature Sensor Table 1. Description of Q7100 Subbases. Use Q7100 T7100 a Install the subbase about 5 ft (1.5m) above the floor in an area with good air circulation at average temperature. See Fig. 1.

RECYCLING NOTICE If this control is replacing a control that contains mercury in a sealed tube, do not place your old control in the trash. Contact your local waste management authority for instructions regarding recycling and the proper disposal of the old thermostat. INSTALLATION When Installing this Product... 1. Read these instructions carefully. Failure to follow the instructions can damage the product or cause a hazardous condition. 2. Check the ratings given in the instructions and on the product to make sure the product is suitable for your application. ®U.S. Registered Trademark Copyright © 1996 Honeywell Inc. • • All Rights Reserved Do not install the subbase where it can be affected by: — drafts, or dead spots behind doors and in corners. — hot or cold air from ducts. — radiant heat from sun or appliances. — concealed pipes and chimneys. — unheated (uncooled) areas such as an outside wall behind the thermostat. Subbase with Remote-Mounted Temperature Sensor(s) Install the subbase in an area that is accessible for setting and adjusting the temperature and settings. Install the remote-mounted sensor(s) about 5 ft (1.5m) above the floor in an area with good air circulation at average temperature. See Fig. 1. Do not mount the sensor(s) where it can be affected by: — drafts, or dead spots behind doors and in corners. — hot or cold air from ducts. — radiant heat from sun or appliances. — concealed pipes and chimneys. — unheated (uncooled) areas such as an outside wall behind the thermostat. If more than one remote sensor is required, they must be arranged in a temperature averaging network consisting of two, three, four, five or nine sensors. See Fig. 2 through 6.

Remove the subbase from the wall and drill two 3/16 inch holes in the wall (if drywall) as marked. For firmer material such as plaster or wood, drill two 7/32 inch holes. Gently tap anchors (provided) into the drilled holes until flush with the wall. 4. Position the subbase over the holes, pulling wires through the wiring opening. 5. Loosely insert the mounting screws into the holes. 6. Tighten mounting screws.

T7047C T T CAUTION T Disconnect power before wiring to prevent electrical shock or equipment damage. 1. Loosen the terminal screws on the back of the thermostat and connect the system wires. See Fig. 8. M4842 Fig. 6. Nine T7047C Sensors providing a temperature averaging network for a T7100/Q7100 Thermostat/Subbase. IMPORTANT Use 18 gauge, color-coded thermostat cable for proper wiring. Subbase Installation 2. Securely tighten each terminal screw. 3. Push excess wire back into the hole. 4. Plug the hole with nonflammable insulation to prevent drafts from affecting the thermostat. The subbase can be mounted horizontally on the wall or a 2 in. x 4 in. wiring box. Position the subbase horizontally on the wall or on a 2 in. x 4 in. wiring box. 1. Position and level the subbase (for appearance only). The thermostat will function properly even when not level. 2. Use a pencil to mark the mounting holes. See Fig. 7.
