Set back thermostat, why?

[ericmark]

Very expensive at £208.64, but why? Found some instructions but clearly not the one I found in the caravan used for our holiday. The problem was 23°C too hot, and 18°C too cold, and waking up at night at a very low temperature not I would hope down to 5°C was not funny.

It was not helped when one could see daylight through the door jamb, and the wall were so thin, sure thinner than my old touring caravan.

I would guess the 5C, was the temperature minimum, when the place was unoccupied, to prevent freezing. The 18C was the normal-occupied setback temperature, though it suggests even that, will time out, after 10 hours. I wonder if it might have an occupation sensor/PIR, to retrigger the 18C?

That is the MI for the one in the pic?

The stat seems to work in dumb mode, in other words it has three positions - 5deg setback frost setting, 18deg normal setpoint and 23deg boost.

The 10Hr run won't be controlled by that device I don't think. I think that may be the sites heating/power system timing that dictated that, was it electric?

 

[ericmark]

was it electric?

No LPG, there was only a 16 amp supply for whole caravan.

 

[Madrab]

OK - So It may have been that the actual heat source would only have been active via it's own timer for those 10 hrs, though that does seem a bit strange given the fact that if it was very cold the caravan would obviously drop to a very low temp outside those 10hrs.

That would probably have been a conversation that would have been had with the site managers at the time methinks.

So you get to be uncomfortable.

at £208 how long is the pay back ? 1 or 2 decades ?

what a totally crap idea, they are 3 temperatures we never use!

23 would be too warm and 18 too cold - the wife would undoubtedly choose the 23 (even though she would normally set it at 20) so it would use more gas, create more CO2 and cost more money

what total plonker designed this ?

On a rental, I guess they were fed up with guests leaving it on and draining the lpg?

I agree on the 23 too warm, but the 18C is what we have the CH set at for most of the day. We find even that, too warm during the night, so the night setback is 14C. The heating never fires during the night setback, at 14C. In the living room, we use a gas fire, normally set on minimum, to add a bit of heat in the evening.

Yes, you don't want to spend more money on gas than you need to, but worrying about more CO2 being emitted is pointless. Britain as a whole contributes less than 1% of global CO2 emissions, so the emissions from ALL gas boilers in Britain are trivial and will have NO effect at all on the world's climate.

Yes, I set living room heating at home to which does not seem to cost us much, but my house a bit better insulated to the caravan.

That was my thought also, would have been better to just make the door fit the door frame we could see daylight between the two.

But I got my trip on the North Yorkshire Moors railway, so not complaining.
