Fan Mode N/A
If you selected a Heat Pump system in Step 1 and
Heat Pump Thermostats in Step 3, then select the
type of Reversing Valve Operation.
Select how you want the Indoor Fan to operate
during Heating Operations. Select HYDRO if you
have an Air-Handler with Hot Water Coil or an
Electric Furnace. Select GAS if your system is a
Gas/Oil Furnace with A/C. If you selected a Heat
Pump system in Step 1, the Fan Mode is set for
you, in which case you’ll see Fan Type N/A.
If you are using an Outside Air Sensor to Lock-Out
the Heat Pump when the outside temperature drops
low enough, choose the Set-Point Temperature.
If the Supply Air Temperature exceeds any Target
Set-Point, (Plus or Minus the Off-Set), the resulting
value becomes the Temperature Limit. Choose an
Off-Set value that will provide a safe operating limit
for your HVAC equipment. The UT3000 will cycle
the system off for 3 minutes, allowing the discharge
air temperature to moderate.
LCD Screen Programming
Select either Heat Pump or regular Heat/Cool
system. If you have a Heat Pump and a Gas/Oil
Furnace, you should still select Heat Pump.
If you selected a Heat Pump system in Step 1,
select whether your Heat Pump has a Furnace
back-up system or Electric Heat back-up.
You can still operate most any Heat Pump in a
restricted mode by using an Outdoor Sensor.
Select the type of 24v (Non-Communicating)
Thermostat you want to use. You may have a
Communicating thermostat in Zone 1 and
Regular 24v thermostats in the other zones.
So you must select which type are in the other zones.
You cannot mix 24v HP and HC type T-stats. All
24v T-stats must be Wired and/or Programmed
for HC or HP Mode of Operation and the correct
Reversing Valve Operation.
Conflicting Zone Demands due to mis-wiring or
incorrect programming will not be honored!
4 Button LCD
Programming
Remember if you are installing a Communicating HVAC system, the programming is done
for you. There is no need to perform these Programming steps. You can still program certain
detail functions ie. (24v T-stat Type). Select only the functions you want or need. Your program
changes take effect in real time and the UT3000 will remember your settings even after a power
failure. When the power is restored, the UT3000 will re-configure the network automatically.
