hi everyone, i'm got to chance my arm tomorrow doing some electrical work around the house... I know someone would say dont touch it if you dont know what your doing, but well the powers off and i can follow instructions, ive changed ligt switches, put new double sockets in etc.idea


as i say ive got some toys.... room thermostat, boiler programmer and underfloor heating wall stat





Basically I'm going to change my own room thermostat



with this one...


First question is from what i can understand is polarity means the wires from the old stat can go into either of the new stat, ive got three wires on the old stat, red, yellow and the blue, is the yellow earth aswell as the yellow and green wire?


Also i've got to replace the boiler programmer with the salus one i bought i havent see the back of the old timer but its like for like form what i can see, are these standard when it comes to wiring them?






Lastly i have a warm up underfloor heating i have a XSTAT wall unit which i believe to be faulty, so i'm going to replace it, the shop i bought it from said its littery like for like.



Would you switch the whole consumer unit off when playing around with the wiring or just the spur switches that feed them, although i think to change the thermostat i will need to switch the whole consumer unit off to be safe.

Red wire to L(com) and yellow wire to SL(NO). Green and yellow to earth and make the blue (neutral) safe.

But it really matter which way around you put the red and yellow.

That Salus Programmer is horrible. We have it in the rental place we're in and if it's too far from the boiler then it doesn't switch it. Check before you screw it on to the wall. It also doesn't seem to be very accurate on temperature. We'll be sweating buckets in the living room but the programmer says it's 19degC and keeps the heating running full pelt. We have to manually override it to turn the boiler off.
