I have a Camray Quartet Boiler, not fully pumped. Its used with a HoneyWell ST699 programmer.
I tried to replace the room thermostat, found that i could not get it to work, so i replaced the old unit.
Now the boiler comes on when HEATING is selected, but it is taking no notice of the room themostat. However the pump is taking notice and cuts in and out with the room stat.
Ive wired the thermostat exacly as before.
Any ideas??
Thanks
