POWER UP
1. Double check wiring, be sure that there are no stray wires or wire
strands at the connections.
2. It is not necessary to connect the remote system (COMM) cable
at this time.
3. Connect power to the control transformer and system. The
display will show all segments for about 5 seconds.
4. Press the Fan key. The fan should come on. Press the Fan key
again. The fan should go off.
5. Set the Mode to "HEAT". Use the up arrow key to raise the
desired temperature setting above the current temperature.
Ensure that the heat pump comes on, in heating mode. After a
few minutes, set the mode to "EM HEAT". The heat pump
should stop and the auxiliary heating should come on. Set the
mode to OFF. Ensure that both the heat pump and auxiliary heat
go off.
6. Set the Mode to "COOL". Use the down arrow key to lower the
desired temperature 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.
Note: As a convenience to the installer, the compressor start up
protection delay can be canceled. To cancel the delay, press the Prog
key 3 times, then press the Fan key 2 times.
If the thermostat or system do not perform as stated above, recheck
all wiring - See Troubleshooting Tips.
