Hi
I’ve inherited this old boiler with our new house. It’s a Thermocompact 620e System Boiler with separate hot water tank.
I’m confused about the wiring as there’s only 1 wire to the boilers control connections as shown below.
Upstairs is the cylinder with 2 motorised valves, connection box and Honeywell timer. Thermostat is in the hall downstairs.
Any ideas how I get this connected up? Anyone know how the boiler controls both heating and hot water from one control wire?
Thanks
Andy
