[Hai-users] HAI RC-2000 Thermostat

[Doug Burton]

I have experienced before that if the incorrect contacts touch when placing
the cover back on, you can blow the fuse on the power supply at the Furnace
itself.  The thermostat may still be intact and functional, but the furnace
blown fuse will not feed any power to the thermostat.


If you hook up the cheap home depot one and not go, do check the low voltage
fuse(s) internal on your furnace,  not the fuse or breaker for the 120v.

 

For what its worth.

I have learned the hard way to never pull a thermostat or put it back on
with it powered up.

My RC-2000 thermostat died when an A/C technician pulled it to test one of
my units during a tune-up, he said all he did was put it back on.  I looked
over the wiring and could not find anything.  I also tested the data cables,
no opens no shorts.
 
Received a replacement from HAI yesterday and it will not power up.  I have
checked the power and the 24volt from the A/C is where its suppose to be.
Any suggestions?  I am about to go to Home Depo and pick up a cheap manual
thermostat just to check the A/C unit.
