I was thinking of bridging the current thermostat wiring and transferring the current built in timer wiring to the Hive due to this using 240v. I figured there would be a way if the built in timer currently sends a 240v signal to the boiler for both the heating and hot water. I believe the Hive also does this.
I have had a look at the wiring diagram for the single channel Hive. Does this also use 240v for the heating on? Just trying to understand why the single channel would work and not the dual channel.
Oh OK, so the single channel Hive is low voltage for heating, but the dual channel Hive is 240v for both heating and hot water?
So a single channel Hive could take the existing thermostat wiring from the 'PT plus' and just add the 240v power supply to it? I guess this is better than the current control over heating.
Is it out of the question to use the 240v signals from the boilers built in timer with a dual channel hive. If the existing thermostat wiring is bridged on the main circuit board it would be always on but the Hive would control it instead using the wiring from the built in timer. This would obviously be the preferred option as I would have control of the water too (and I already have the dual channel Hive).
I may still be able to swap the Hive but I want to be absolutely sure I can't get the dual channel working.
