Well, I have your answer - by mistake trial and error. I have a new Hunter 44260 digital. What the following setup is doing is causing the A/C fan (not the compressor) to come on when the heater is activated. Not what I wanted, but it is what I got! I do not know if this is good or bad for my system?? With this setup, it seems like everything is working OK, both heat and cool, but is it OK?
I Upgraded from a Duo-Therm, tstat using a Duo-therm AC with a suburban gas heater
old Duo-Therm Terminal wiring was -
7.5 volt and had a red wire connected
Cool – had a Yellow wire connected
Fur – Had a White Wire connected
Hi-Fan – had a Blue wire connected
Fan - had a Tan (or Brownish) wire connected
Gnd – had a Green wire connected
The Hunter Model 44260 (From Amazon)
is Connected as follows:
Red wire NOT Used
Yellow wire connected to “Y”
White wire connected to “W”
Green wire connected to “RC” (Rc has Jumper to Rh)
Blue wire connected to “G”
Tan wire connected to “G”
Y-1 connector left blank
I know this is WRONG! But, it is what I did get. I am still trying to figure out my correct connections, which is how I found this link.
NOW, if ANYONE can help me - I am very frustrated. I can not get my wiring to work as designed on any of the MANY diagrams I have found on line.
Can anyone tell me what I am doing wrong on the above noted wiring?
I think my white - furnace wire is OK, my Yellow Cool wire is OK.
I know my blue wire is HI-Fan, MY Tan(brownish) wire is Lo-fan and my Green wire is also Fan.
1st, let me clarify that my new Hunter 44260 stat uses batteries and not supposed to need power from the TT. (refers to Red wire usage or not, I think)
2nd, I am going to work on this a little later today but I have a ?? If when using a spst switch in the blue Hi-fan wire, it would be connected between the blue wire and "G" terminal, along with the "Tan-low fan wire" already connected to "G". So, when the fan is called, and the spst switch is in the hi-fan position, are not BOTH the blue wire and the tan wire both connected to the "G" terminal at the same time?
In your comment you suggest only one (blue or tan) would be connected, EITHER but not both?
I think I did try your wiring suggestion (with the exception of the "either of the blue or tan" and did not get a correct operation, but will try it again today, with much better hopes!!
3rd, I spoke to the Hunter customer Support on Friday and his final suggestion was to call an a/c-heating electrical engineer or RV A/C professional out to resolve my issue. He also told me that for the Suburban Gas, Direct Spark Ignition, the t'stat HG/HE switch should be set to HE, as it is Electric Ignition and the HG setting will cause problems down the road. (any thought there?) seems contrary to the simple gas vs electric concept?
Something so simple should not be so dang confusing!! 1,000s of pages of help on this very subject, different models but still same subject, just more confusing. Every expert very confident in their wiring plan but - none have worked correctly so far on this one.
