Hello lovely people
I have Valiant 428 heat-only boiler on S-plan Plus pipework.
3 heating zones are controlled by 3 Nest thermostats via Switched Live Terminal 4.
System water temperature is set at constant 45C.
Lovely config.
Now can I add Vaillant eBus Weather Compensation product (VRC series?)
to this Switched Live controlled boiler?
I want to have the flow temperature of system water
to be dependent on outside temperature.
Ideally, a product that sits in the boiler fascia,
takes outside temperature from Internet via Wi-Fi,
and sets the system water temperature automatically via eBus.
Any Vaillant gurus here?
