I would like to install a Nest thermostat (just for the design, possible savings and control via the Internet is nice).
I went on the Nest website and did some reading here and there and apparently the Nest thermostat is a simple on/off switch to the boiler. Therefore, the Nest thermostat itself only uses 2 wires (crusted = on I assume).
However, I opened up my current thermostat and there I see 4 wires (see picture). Is also normal that it is a bit more complicated because I can select night and day and separately set temperature for day and night ed.
The boiler is controlled by an Elco Klockner Logon M (see photo). I assume that this is in direct connection with the thermostat. The Elco controls 2 circuits (underfloor heating and radiators).
So at first sight I don't see how I can connect a Nest, so I wonder if there is anyone with experience with similar installations and Nest?
It has to work somehow I think, I could set the Elco to always be in 'day' mode (no more day/night) and then use the Nest to tell me when heating is required.
I know there is another box in between, the Heat Link, that should probably go to the Elco and then of the 4 wires to the current thermostat I only use 2 to go from the Heat Link to the Nest thermostat.
Any help or advice is welcome!
Thanks in advance!
