Rev O Valve Light

[funat120mph]

Hi,

I have a UZC 4 hooked up to a 1 Stage Heat 2 Stage Cool Electric Conventional Air Conditioner.

Currently I have one zone stat wired up and the HVAC equipment wired. Everything works as expected. My question is that I have the REV O Valve light lit up on the panel. I don't have a heat pump so I'm a little confused as to why this is lit up.

Any help would be appreciated.

Thanks

Sound like the board is still set for heat pump, check dip switch #1 Bank #1 (system) should be on Gas. Later board that light would automatic come on as a function of the board, but with nothing wired to the out put "O" nothing will happen.

Bank 1 dip switch 1 is set to gas.

I will toggle the switch. Do I need to turn power off to the board for all dip switch changes and timer/temp changes such as the staging timer/oas?

Thanks.

Sound like the board is still situated for hotness pump, check dip switch ought to be on Gas. Later board that light would programmed go ahead as a capacity of the board, yet with nothing wired to the yield nothing will happen.
