i connected up a heating system the other day with a wireless room stat supplied by the plumber not that that matters. 2 zone valves.

i have connected it up the same as a normal system, from the heating on core from the programmer, through the stat to the valve.

What that means is that whilst the heating timer is off there is no power to the receiver. so if whilst the clock is off the stat decides to call for heat the receiver is off so misses the signal. then when the clock comes on at a later time the heating won't come on because the signal has already been sent if you get my drift. What am i missing or will it call again when the receiver comes on.

We use the altec wireless stat, depending on what make you have got you might need to marry the stat with the receiver each time the heating comes on.

You would be much better using the volt free connections that switch upon receiving of signal.


Looks like a return visit for you

Gary,

The receiver needs a constant supply, then the programmer feed goes through the contacts to the valve


Been there, done that

Permanent live to receiver for supply and H/W live from programmer to switch contact on receiver for control.

Normally, after fitting wireless thermostat the original programmer has to be set to CH permanently on (just used for DHW now) because there is now another programmer in the thermostat.

Or rewire to bypass/ignore the original programmer CH control.

True - but if this one is not then there is not a problem.
