Hi Guys
I'm not seeking to install this, just get an understanding of why i'm being told what I am. I'm going to pay a professional to install it but still want to understand how it works...
I recently thought it'd be a good idea to get a Nest Thermostat 3rd gen, our thermostat in our house is woefully situated and we figured we'd save a small fortune on having it learn when we are out of the house.. after a bit of research we figured it'd work with our boiler and bought it.
I was quoted £20 by our regular gas tech to fit it on top of the normal price for a service.. bargain... I thought. We'd understood that it should be a simple switch to replace the existing programmer for the nest.
But he arrived and had a bit of an issue with the whole thing, mentioned the motorized valves, thermostats, decided I needed to buy two heat links and pretty much left the building.
Our Setup:
Icos HE24 boiler
Room Thermostat
Programmer that does heating + water...
Motorized valve ground floor for entire radiator system
Motorized vavle beside hot water tank for hot water
S-Plan Wiring System
My admittedly laymans understand of the whole thing was that the Heatlink would just be a fancier version of my existing programmer. Ideally we would just leave the room thermostat in place but either a) disconnected or b) turned up to max to make it not an issue. The thought then was that the Heatlink would control both the hot water and radiators from the thermostat in our living room.
I'm told that I will need to either have two heat links or run a wire between both motorized valves to my heat link.
Having then decided to phone a nest pro he's suggested a wire between the systems may be required. Admittedly he has not seen my system.
But the house is less than 10 years old, built by a reasonably reputable builder so i'd doubt the install is too whacky.
Is anyone able to explain why this is the case? I would have thought the heat link would command both motorized valves just as the programmer does currently.
Bit Baffled by it all. Any light that can be shed on this would be gratefully appreciated.
