Thermostat help
« on: October 20, 2013, 01:55:17 PM »
I need help hooking up two thermostats.
First one is round honeywell  type I want that to control my propane forced air
next one is a digital LUX 1500e I want it to control blower only when using outdoor furnace and to controll my ac

The wire ports I have in the lux are G,   (RH RC they are jumped) Y W C
In the round Hineywell I have R W

I have six wires green, white, black, red, yellow and blue

Which wire colors go to what points on your forced air system, or are both ends not connected?

You will also still want to turn on the fan with the Honeywell, it has no G ?

Can you take a look in the furnace and verify that all the wires are to the correct terminals?
red should be on RH, green should be on G, yellow should be on Y, white should be on W. The blue or the black may be the common, should be checked to make sure as it isn't the normal color for that.

Anyway, assuming all the wires I mentioned are on the correct terminals, on the Lux thermostat, connect the red to RH, the green to W, yellow to Y. Then run a jumper wire from the RH in the Lux to the RH in the round honeywell. Also connect the white wire to the W in the round thermostat.

After checking in the furnace if there is a wire on the C terminal, connect that to the C in the new thermostat also. If nothing is on it and those two wires aren't used, you could connect one of them at both ends. Otherwise you will need batteries to power the thermostat. If it doesn't have that option then it just won't work.
