Hi,
We currently have a Switchmaster Sm400 timer (the kind that has water or heating AND water, but not just heating) and a Satchwell (now Sunvic) TLX2203 thermostat (analogue). The thermostat has three wires (plus earth): Red, blue and yellow. I'd like to replace this with a new seimans RDD10 (the mains version, not the 10.1 battery one).
My question is this: as the thermostat would be mains powered, would it only get power when the timer is on (i.e. the two hour period when we have the timer set to heat water)? Can this be changed by rewiring the timer? If not, would the battery version solve the problem?
Thanks for any advice you can offer.
Steve
