Communicating Zone Control System
Addendum sheet for UT3000
Code versions 1.17, 1.18, 1.19
APPLIES TO DAIKIN INVERTER SYSTEMS
STOP & read this bulletin before you start the
system or perform repairs on the sealed system!
EWC Controls is proud to announce that the Ultra-Zone® UT3000 Zone Control has been approved to
operate with the Daikin® Inverter A/C and the Daikin® Inverter Heat Pump ComfortNet™ systems!
The Daikin Inverter A/C or HP will provide variable BTU capacity based on a proportional demand from
the ComfortNet CTK04 thermostat or the Ultra-Zone UT3000 zone controller.
If you are installing a Daikin inverter ComfortNet system and a ComfortNet CTK04 thermostat, along
with the Ultra-Zone UT3000, the detailed start-up instructions on page 2 apply to you.
Upon power-up, the CTK04 communicating thermostat must perform a “System Test” on the Inverter
system. This test is required to calibrate the Inverter system settings and parameters. Normal cooling
and heating operation is not allowed until this test is complete.
The “System Test” may last 5 to 15 minutes (or longer) and must not be interrupted. In order to ensure
the “System Test” is not interrupted, the test must be performed independent of the UT3000 zone
control.
Follow these steps to perform a “System Test” verify “Refrigerant Charge” or “System Pump-Down”:
1. Connect a CTK04 directly to the Inverter A/C, HP and Air Handler or Furnace as shown on page 2.
2. Do not power up the UT3000 zone panel until the following task(s) are completed successfully.
3. See the Daikin Inverter Condensing Unit Installation and Service Reference for instructions on
performing the “System Test” verifying the “Refrigerant Charge” or “System Pump-Down” for repairs.
4. After the system test is complete and the refrigerant charge has been verified, you may decide to
access the Advanced Menu and modify other settings (Cool or Heat Trim Settings, Cooling Profile,
Temperature Rise, Clear Diagnostic Faults, etc). Otherwise, proceed to Step 5.
5. After these tasks have been performed, connect the CTK04 thermostat to Zone #1, 2 or 3 of the
UT3000 zone panel.
6. Power-up the UT3000 and complete the zoning installation.
New UT3000 menu items are listed on page 3 of this bulletin. Updated twinning instructions are
detailed on pages 4 & 5, and an updated troubleshooting guide is provided on page 6.

UT3000 PANEL TWINNING PROCEDURE
3000
PATENT PENDING
Refer to the Graphic on Page 5
1. Mount Panel “A” and Panel “B” in close proximity to the HVAC system and each other.
2. Install a dedicated 24v 60va listed transformer and run 24v power to both UT3000’s. DO NOT use
separate transformers! * Do not power up yet.
3. Connect the communicating HVAC system to the Panel “A” communicating SYSTEM block.
4. Connect communicating and/or legacy 24v thermostats to Panel “A” as desired.
5. Connect legacy 24v thermostats to Panel “B”. Communicating thermostats will work on Panel “B” but
they cannot digitally access the communicating HVAC system. If these functions are not important, then
you may use communicating thermostats on Panel “B”.
6. Connect the twinning wire connections between the Dry SYSTEM output block of Panel “B” to the
legacy 24v Zone 1 T-stat input of Panel “A”. Cross-wire to match the Heat/Cool application or the Heat
Pump application. See graphics on Page 5.
7. Install one Supply Air Sensor and connect the wires to the SAS terminals of Panel “A”.
8. Install the other Supply Air Sensor and connect the wires to the SAS terminals of Panel “B”.
9. Now, Power Up the communicating HVAC system and power up the UT3000’s.
10. Panel “A” will automatically configure and talk to the communicating HVAC system.
11. Communicating thermostats connected to Panel “A” will also configure automatically.
12. If using 24v legacy T-stats, program Panel “A” for the type of 24v thermostats being used.
* The UT3000 defaults to Heat/Cool type 24v T-stats. Change to Heat Pump type if necessary.
13. Program Panel “B” to match the HVAC system type shown in the Menu screen on Panel “A”.
14. Program the Panel “B” feature “DMP DFLT” to the CLOSE position.
15. Program Panel “B” to match the same 24v legacy T-stat type programmed into Panel “A”.
16. Program the Panel “B” feature “OAS SP” and select the OFF position.
17. Program the Panel “A” feature “Legacy DMD” to 100% to ensure Panel “B” demands carry the
maximum demand weight.
18. Set all thermostats to operational mode and operate the HVAC system in both Heating and Cooling
modes, to confirm proper operation. Call EWC Controls Engineering Dept. if you have questions.

create a five zone system. The Dry System Output of Panel “B” is crosswired to Panel “A” at the 24v legacy thermostat input of Zone 1.
The cross-wiring shown above is for a gas/electric application. Use the
cross-wiring diagram to the left (Figure 6) if your application is a Heat
Pump.

Panel “A” is directly connected to the Communicating HVAC system.
Thus, Panel “B” must be manually programmed to match the type of
HVAC system being controlled by Panel “A”.
Communicating or 24v legacy Thermostats may be used on panel “A”.
Panel “B” should have 24v legacy thermostats only, and you must specify
which type of 24v legacy thermostat (Heat/Cool or Heat Pump) you want
to use on Panel “B”.
The Legacy Demand feature (Legacy DMD) on Panel “A” should be set to
100%, so the Zone 1 legacy input from Panel “B” carries the maximum
demand weight. Refer to the detailed twinning instructions on page 4.

malfunctioning. Communicating
T-stat displays fault messages.
Check HVAC system field wiring for proper connections, continuity & shorts.
Some HVAC systems require a “System Test” prior to normal operation.
Connect communicating T-stat directly to HVAC system & perform System Test.
Check DATA voltages: C to Data 1 =2.8, C to Data 2 =2.2 or C to Data 1 =1.9vdc. C to Data 2 =1.3vdc.
Check two BIAS switch settings on the UT3000 panel. Try turning them off.
Data voltages are incorrect. LCD &
LED’s are responding properly and/or 24v Commons must be phased when using separate transformers on outdoor and indoor units.
Check Zone thermostats for proper connections. Test wires for Continuity/Shorts.

CHECK YOUR WIRING
DETECTING 24vac SHORTS
SYMPTOM: Entire Panel or a Single Zone appears to be dead!
HVAC system not responding and
UT3000 LED’s are off.
Dampers not responding and The
UT3000 LED’s are off.
If 24vac short has occurred, 24vac will be present at the UT3000 24v Input
terminals R & C; but 24vac will not be present at any Thermostat R&C.
ISOLATING 24vac SHORTS
Disconnect the wire(s) from the ‘R’ terminals on the UT3000 thermostat
terminal blocks , and the “C/PO/PC’’ terminals on the UT3000 damper motor
terminal blocks. Restore power. If the short is no longer present, Ohm out the
thermostat and damper field wiring for continuity, shorts to common and/or
shorts to earth ground. Replace or repair wires as necessary. Restore power.
140mA & 500mA circuit breakers
protect the UT3000 and react to a
short in the Thermostat/Damper
component field wiring.
SOLUTIONS: Remove 24vac power from UT3000 and allow F1 circuit breaker to cool!
Find and repair short(s) in damper and/or thermostat field wiring. Restore 24 vac power.
Detecting 24v shorts to common or shorts to earth ground
When the 2.5A breaker is tripped it will get hot to the touch and none of the panel LED’s will illuminate. The
LCD will also cease to function. To reset the breaker, locate the short by removing each hot wire connected to the
panel, one at a time. When the shorted wire is removed, the panel will resume normal functions. Now you must
repair or replace the shorted wire. If one or more 140mA or 500mA breakers trip, only the device(s) connected to
that block will be affected. Remove each hot wire connected to that block until the voltage is restored. Find and
repair the short before re-connecting the wires. If there is a short between the Data 1 & 2 wires or if the Data wires
are shorted to 24v or earth ground, the Communicating thermostat on that zone will alert you by displaying “Call
for Service”. If no communicating thermostat is connected and a short occurs on the 24v wires, that zone will not
function. Find and repair the short using the methods described above.
