Hello, hoping someone can help. First time wiring a thermostat.
I currently have 2 zone heating (downstairs & upstairs). My setup is as follows:
System boiler (valliant)
Megaflo hot water tank
Honeywell valves for each zone
Programmer for heating and hot water where the heating is set to constantly 'on'
2 Heatmiser touch thermostats to control each zone - upstairs and downstairs
I am looking to replace the upstairs thermostat with a Nest E but I am not sure which of the wires need to be connected to Common and NO ports on the nest e thermostat.
I have attached an image of the current wiring to the heatmiser thermostat and a screenshot from the heatmiser manual with wiring guide.
Based on this should A1 be connected common and A2 connected to NO with L and N being terminated?
Apreciate any help. Thanks!
