Hi. I'm Joe and I will be glad to help you out.
What does the jumper wire connect on the old thermostat?
It connected to RH & RC on the White Rodgers
There should be one on the new tstat between R and Rc
There is an R and a separate RC next to each other. I connected the RC wire to RC but did not feel comfortable connecting the jumper to RC with the existing wire. On the old thermostate the wires were on opposite sides of the screw.
Did you have separate wires going to Rh and Rc on the old one, or 1 wire to Rc then a jumper to Rh?
There was one wire to RC and the jumper to RH & RC
There was also a C connection which the honeywell states should not be used.
ok. Put the jumper between R and Rc on the new one and we can test it.
Right. I would just tape the C wire up
Ok..I have to turn off the power again...can you hold?
Sure. I'll stand by
Just to confirm, I should place one end of the jumper in the RC with the existing wire?
Ok, think I have it connected.
Ready to test it?
Going to turn power back on now
I have turned thermostat up and waiting to see if heater comes on
Yes, it has just started!!
Thank you Mr. Spivco...I was hesitant to pay for this service, but considering I paid $89 for an HVAC company to tell me the thermostat was bad I will not complain. So, the two wires begin together will not cause a problem?
Not at all. They have them separated because some systems need 2 wires hooked up, but most do require the jumper.
Wonderful and I can feel the heat coming through..I appreciate your expertise in this matter.
You're welcome. Have a great weekend!
The same to you
