Hi there.
I have very little experience wiring boilers and will be required to wire a Valliant 837 soon with an external thermostat (not sure on model)
I understand the thermostat controller can be wired as 24v or 230v.
On the wiring diagram, there is a connecton called RT (for 230v) which says it's for the thermostat. So does the thermostat controller require a permanent live and neutral from the load side of the FCU and a connection from terminal RT?
For 24v, does the thermostat just require a 2 core from the connections labelled as 24 RT?
Much appreciated
