I'd be grateful for any help with this ...
I'm looking to replace my Honeywell ST9400C CH/HW controller (with existing Honeywell wireless thermostat) with dual channel Hive.
Do I just leave the existing wireless thermostat receiver as it is or do I have to do anything to decommission it?
The wiring inside the Honeywell pretty much corresponds with the Hive, assuming it's OK that the "off" terminals and the earth terminal are all empty.
