Question about Honeywell Programmable Thermostat Heater
I switched out my old digital thermostat (Blue Dot factory one) for the Honeywell RTH230B programmable one. My old one has W,Y,O(Not in use),R,C,G and the new one has W,Y,G,Rh,Rc. I put the wires as follows W-W,Y-Y,R-Rh,C-Rc,G-G but my AC will not come on. The heat works fine as I tested it out but the AC symbol blinks as stated in the instructions for compressor safety, but when it goes solid the AC should kick on and it doesn't. I put my old one back up and it works fine. I've done the porcess twice trying to trouble shoot and make sure everything is secure and correct w/ no luck. What could be going wrong?
Make sure you jumper R to rh. Russ

Page 26 27 of the users guild states that thermostat has a fail safe preventing one system to turn on immediately after the other system has been on say you turn on heater to test then try to turn on cooling to test well cooling wont turn on immediately to prevent damage to system..
