CONFIGURATION

The “System Type” for this thermostat must be set to “Heat Pump” under “System Options”.

1. Double check wiring, be sure that there are no stray wires or wire strands at the connections.
2. Connect power to the transformer and system. The display will show all of the thermostat settings.
3. Press [FAN] and select “On”. The fan should come on.
4. Press [FAN] and select “Auto”. The fan should go off.
5. Press [HOLD] and select “On” to override Energy Efficient Control.
6. Set the Mode to "Heat". Raise the desired heat setting 1 degree above the current temperature. Ensure
that the heat pump comes on, in heating mode. After a few minutes, raise the desired heat setting 3
degrees above the current temperature. Auxiliary heat should come on. After a few minutes, set the
mode to "EM Heat". The heat pump should stop but the auxiliary heat should remain on. Set the mode to
“Off”. Ensure that both the heat pump and auxiliary heat go off.
7. Set the Mode to "Cool". Lower the desired cool setting below the current temperature. Ensure that the
heat pump comes on, in cooling mode. Set the mode to "Off". Ensure that the cooling unit goes off.
8. Press [HOLD] and select “Off” to enable Energy Efficient Control.
