heating comes on with water when both on at timer. put heating only on at timer heating does not come on and dose not respond to thermostat which is a new one. boiler stat is at two. if I turn the frost stat to max which is 20c the heating will come on up to that temp but will still ignore the room thermostat. checked all wiring seems fine
anyone got any ideas or had this problem.

thanks for that but power ok that's what is baffling me I am now looking at the connection box and redoing all the wiring could be a iffy connection what do you think.

I have put a new controller on it is danfoss but this one is EP175 IS probably updated the one I took of which seemed to be working, was just EP175 but all connections are the same.
