I am trying to delay my indoor fan start by a few seconds to prevent cold blow; application is residential add on heat pump.
I have wired a TD69 in series between the G terminal from an Aube TH146NU base module and the fan relay RC485.
I have tried two different timers and can't get any time delay; the fan relay energizes immediately on G call. I have checked all the obvious.
Have you ever seen a DOM or DOB relay not time for some "mysterious" reason?
Stumped by the elemetary!
