ACCESSORIES:
Model SAS – Supply Air Sensor (Included)

Model CPLS – Coil Protection Lockout Switch (Optional/Recommended)
MOUNT:
Choose a suitable location to mount the UT3000 housing. Likely locations are the
Return Duct, a Nearby Wall or Convenient Studs where plywood can be installed
to support the housing. Avoid mounting the UT3000 on the Supply duct. Do not
mount the UT3000 directly to any Air-Handler, Furnace, Hot Water Coil or
Evaporator Cabinet to avoid damage to these devices.
Follow National and/or Local Mechanical Code.
POWER:
EWC always recommends to install a separate transformer to power the UT3000.
Follow NEC and/or Local Electrical Code.
WIRE:
Connect your thermostats and your dampers. Use the provided knock-outs as the
wire entry-way. Strip the jacket back to where the cable enters the housing. That
makes for less bulk and allows easy routing of the wires for a clean install.
4 Wire Comm Network:
Adhere to the Climate Talk™ Color Code. RED, GREEN, YELLOW, WHITE. Doing
so reduces the possibility of mis-wiring between devices on the Network.
PROGRAM:
When connected to a Fully Communicating HVAC system, programming is
not required. The UT3000 will automatically configure the entire system and start
running as soon as thermostat demands are detected. Allow at least 1-2 minutes
for all Thermostats and the HVAC system to fully configure on the network.
The Default Supply air temperature Targets and off-set Limits will be used. Other
unique features can be selected and/or you can adjust the default settings
yourself.
When connected to a Conventional 24v HVAC system, you simply scroll thru the
LCD menu and select the type of HVAC system you have and the type of
thermostats you want to use. The Default Supply air temperature Targets and off-
set Limits will be used, or you can adjust your own settings.
FINISH:
When the Installation is complete, run the system thru it’s paces and observe the
operation of the HVAC system in all possible modes of operation. Check the Zone
Dampers and the Bypass Damper for proper operation. Balance the System and
make adjustments as necessary.
If you need help, call the Technical Support Hotline for assistance 800-446-3110.
