2. If the issue is still occurring, disconnect external controller from the heat pump. Then check operation at heat
pump.
If display panel responds, the problem lies with the external controller or its installation. Contact the
l
manufacturer of the external control device.
Heat Pump Not Running
1. Confirm equipment is receiving power. Is the heat pump display illuminated?
If not, confirm the main breaker (located at the power supply panel) and the disconnect switch (located near

the heat pump) are both turned on.
If the display still does not illuminate, it is recommended that the heat pump installer or electrician confirms
l
heat pump is receiving power.
2. Confirm correct mode is selected.
