wiring 's' plan into eco hometec boiler.

1oldspindle · 18 Jan 2010

Hello all,
has any plumb or spark ever wired a 's' plan with a Horstman 3 channel programer into a 'eco hometec' condensing combi boiler, and if so how did you go about duffing out the inbuilt programer? I need to know as i have not got an internal wiring diagram for the boiler circuitry.
Many thanks for any help.

Whats an eco hometec and cant the built in timer just be unplugged from the pcb

Usually the boilers inbuilt timeclock can be set for 24/7 and the external system wired to take the place of the external thermostat.

Then the switches in the motor valves are wired in series with that circuit.

I agree with my mate Telly Tony Agile & all the MV's orange wires will be connected to the boiler Sw/live.
