SOURCE: changing a room thermostat a potterton to honeywell t6360

I think I've done it - but don't take this as absolute truth.
For the Honeywell T6360B the original Potterton wiring should be rewired as follows:
Brown [Live] goes to terminal 1; Blue [neutral] goes to Terminal 2 and the yellow/green [which is not an earth but a switched live - i.e. gives live to the heating system when the thermostat clicks in] goes to terminal 3.
Obviously all done with the power isolated and when it was switched back on we had heating again :o)
It's been on over two hours now and all seems fine.

SOURCE: honeywell thermostat

I had the same problem and decided to take a chance and call honeywell customer support. I am shocked, they solved my problem! At least in my situation we found that the blue wire ran the compressor. Instead of hooking up to "blue" on the thermostat, we hooked it up to "white." It works wonderfully now.

SOURCE: Installing thermostat - extra wire?

you have to go down to your furnace and follow the thermostat wire ...it connects to a terminal strip or fan centre...the color doesn;t really matter...installers mix and match all the time....look at the furnace wiring and mark it down...Red on "R"...Green on "Y" whatever it is...and connect it accordingly upstairs...if you only have 4 thermostat wires downstairs you will need a jumper wire between RH and RC...if you have 5 wires you will see 2 wires on "R" at the furnace.,...and connect either to RH and RC at the thermostat

My thermostat is set on 68 degrees and it shows room temperature is 68, but the furnace still kickson, Honeywell said it has a 1 degree difference. so what's the problem then?


Yes there is a one degree tolerance, in fact my heater just kicked on and it is set to 67 and the inside temperature reads 67. It is also a Honeywell.

My termost set to a/c, the fan auto, blow very well, but when I switch to heat and the fan auto, doesn't work, but if I put fan on work why?


the thermostat says to call for heat buildup in the work if its not cold enough the thermostat won't call for heat and I won't go on but when it gets cold and the thermostat set to the temperature you want or hire someone that doesn't cycle

Conair Lysol hand held steamer


Does it tell you to add salt to the water?(I have a cheapo little steamer that requires salt to increase the conductivity of the water-it just creates steam by running AC voltage through the water in the tank)

Flashing re co


Re Co stands for Recovery Mode. That means if you have programed your thermostat to be at say 72° at 5:00 then it should kick on in Recovery Mode several minutes before 5 in order to reach that temperature. This is normal and doesn't indicate that something is wrong, just that your thermostat is trying to reach or recover the programed temperature.
