Hi everyone, I’be never posted on here before but I’m looking for some advice.
I currently have a Siemens RDJ10RF wireless thermostat which communicates with a Siemens RCR10/433-GB. The latter is wired to the boiler with a red and black wire to L and N respectively and brown wire to L1 and Blue wire to LX and a yellow/green wire. (See pic)
I’m looking to replace this with a Nest E so will have to replace the box connected to the boiler with the heat link e. I know the heat link e is battery operated so I know I won’t need the L and N feed but I’m a little confused with the other 3 wires. The options for the heat link e are labelled C, NO, FP, OT1 and OT2.
Any help would be greatly appreciated.
