If your Emergency Light is coming on in the Heat Pump mode that is more than likely because you have the boards Auxiliary End Switch set to the Reverse Acting mode not the Direct Acting mode. This is not a problem if you are using the panel for dehumidification purposes. If you are not, take a look at Dip Switch number 5 on bank 2. Is it set to the left or to the right? It should be to the right toward DA. Please let me know if you have any further issues.
