Hi
Recently had a new central heating system installed - something is not quite right with it though. I've had a heating engineer out to look at it twice but still not resolved.
I have a Drayton MiTime T740R programmer with two MiStat N1 10R thermostats - one for upstairs and one for downstairs heating.
When I turn the downstairs heating on, the valve opens but the pump and boiler doesn't activate. It's only when I then turn on the upstairs heating or the hot water, does the pump and boiler activate and heat flows to my downstairs heating as the valve is already open.
On the programmer, the upstairs heating zone states the current temperature and the thermostat temperature, as it should. But this information is not displayed for the downstairs heating zone. Instead, this information is stated for the hot water zone on the programmer.
This obviously isn't right. I'm wondering if the downstairs thermostat needs to be re-bound to the downstairs heating zone on the programmer? Or is it the wiring that is wrong - could there be two wires from the downstairs heating valve and the hot water valve that need to be switched over?
Any advice gratefully received.
Thanks
Chris
