Problem with Honeywell RTH230B thermostat
Hi,
I have hooked up the thermostat (replaced an old analog Honeywell unit) and had the same wiring as the one on this post
https://www.askmehelpdesk.com/...ead.php?t=14531
(ie on the old unit, the blue wire to the Y terminal and a yellow jumper wire from the Y terminal the back of the unit - current wiring on the RTH230B is White to W, Red to Rc/RH, Green to G, Blue to Y).
Anyway, everything seems to work fine. The fan control works, the AC comes on when switched to cool and the furnace comes on when switched to heat. My problem is no matter what I set the temperature to, the unit comes on and does not shut off. Even when the desired temperature has been overshot by 10 degrees (ie unit set to heat, desired temp 70, actual temp is 80 and the unit is still on). I have brand new batteries in the unit.
Is it possible I have wired something wired wrong, or do I just have a defective unit?
Any help would be greatly appreciated.
Thanks,
Dave
