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

Remote not workin


what's happened here is the cm61 ng and the reciver box have lost there connection you will have to "rebind" them then it will be fine -




THE BINDING OPERATION DESCRIBED BELOW IS REQUIRED IF:

· Any of the system components (room unit or relay box) are replaced

· HC60NG has incorrect or no binding data stored (e.g. when pre-bound system pack components have been mismatched)

· Interference with the RF signal has caused a communication failure

During the binding procedure keep approximately 1m distance between the room unit and the HC60NG

1 Turn off mains supply to HC60NG for 10 seconds. Re-connect supply.

2 Press and hold the HC60NG push button for 15 seconds to reset previously stored data. The red LED will start to flash at 0.1 s on/0.9 s off. Release the push button.

3 Press and hold the HC60NG push button for 5 seconds to enter the binding mode. Red LED flashing at 0.5 s on/0.5 off confirms the binding mode has been entered.

4 Move the CM67NG slider to the OFF position (CM61 push the OFF button) and press the TEMP , TEMP and PROG 1 buttons together. The CM61/67NG will display InSt.

5 Press the i button to send the binding signal. The red LED is switched off on the receiver box to confirm the successful binding operation. If the red light still flashes push the repeat steps 1-3 and press the the i button until binding is successful.


hope this is helpful

Thermostat


That thermostat must be used with a THM5421C1008 Equipment Interface Module. The thermostat communicates with the module and the module is connected to the HVAC components.
