Any stat that has BOTH O & B which is getting hard to find. The old W-R 1F80-361 did if you can still find. Or maybe it is time to put the TAT out to pasture!
Have a customer with an old 2 zone Honeywell Trol-A-Temp mini-zone 2 control. She wants to change Tstats to digital. My problem is with the zone 1 tstat. The O and B terminals used by the control to change over from heat to cool on zone 1 tstat base. What digital tstat will work with this control?

So will any heat pump tstat work?
