If the dehumidifier temperature sensor is not working, check the sensor. For resistance reading, see Table 13.
What to do if my IBC Air Handlers outdoor temperature sensor is not working?
If the outdoor temperature sensor is not working, check the sensor. For resistance reading, see Table 13.
Why is the IBC Air Handlers pump not energized?
The pump might not be energized for several reasons. First, in the IBCconnect app, under Advanced Settings, ensure that Pump Enabled is set to "on". Also, in Basic Settings, confirm that Heat Mode is not set to "Heat Pump", as the AHU pump is not energized during Stage 1 heat pump heating to prevent interference with circulation. It will be energized at Stage 2 call for heat. Finally, check the AHU board for a blown 10A pump fuse.
