I have a Potterton boiler controlled by a ST6400C that i was considering upgrading to a smart heating system. I'm struggling to understand due to the way my system is wired what i could replace it with?
I have 2 CM707 thermostats, one for ground floor and the other for 1st and 2nd floors. The DHW seems to be a simple swap for a dual channel smart controller. The Heating though I don't understand. Even though i have a 2 zone system it's controlled by 1 channel on the controller, this then heats either zone depending on the individual thermostat.
With for example a hive system, I'd need a dual channel receiver for DHW and one thermostat and another single channel receiver for the second thermostat. So I could wire the 2 channel as a direct replacement for the ST6400C but then when i look at the second receiver there's not a separate switch wire for that circuit. Could a link be put in from the single channel to the 2 channel receivers so either or both would fire up the heating circuit. Or does the wiring need to be changed to give two independant wiring circuits for the two zones
Considered swapping out downstairs zone and DHW with a 2 channel receiver and leaving the CM707 to control second zone, but then if zone 1 isn't calling for heating the 2nd zone wouldn't be kicking in on that thermostat?
I have three valves in the airing cupboard, for the 2 heating zones and DHW. I was also thinking an alternative could be to link out the second thermostat and turn it into a single zone heating system. All radiators have TRVs except one on each zone.
Any suggestions or advice welcome, many thanks
