What to do if the Dettson Air Conditioner interface has stopped operation?
If the Dettson Air Conditioner interface has stopped, there could be several reasons. First, the supply voltage might be too low; ensure that 24VAC are reaching the R-C connections. Second, a high voltage or EMI event might have occurred; verify the connections. As a general step, try cycling the power to the unit.
Why is my Dettson Air Conditioner interface not communicating with the modulating furnace?
If your Dettson Air Conditioner interface isn't communicating with the modulating furnace, and the LED is mostly ON but turns OFF briefly, the “1” and “2” wires are likely reversed. Turn off the power to both the furnace and the outdoor unit, invert the “1” and “2” wires, and then turn both units back on.
What to do if the Dettson Air Conditioner interface does not receive communication signals from the outdoor unit?
If the Dettson Air Conditioner interface isn't receiving communication signals from the outdoor unit, it could be due to improper connections. Ensure the connections are made as per Figure 13, Figure 14 and Figure 15. Also, try cycling the power of both units.
