Themostat Control

What are you trying to achieve? Most programable stats have a "holiday" function wich suspends the programmed 5+2 or 7 day sequence for n days.

Also remember that the 5+2 or 7 day programming is a pattern that repeats, it's not just for 5+2 or 7 days into the future. Once set it's forget. B-)

I am way alot and need to program it to heat the house on my return i.e. every 4 weeks.

Thats what the "holiday" feature does. It suspends the normal 5+2 or 7 day cycle for n days. You can set the value of n normally up to 99 days and the temperature below which you don't want the house to fall for frost protection. After the n days are up the normal cycle restarts.

OK you'd have to set it each time you left for the duration of your absence but I don't know of an off the shelf solution that will do repetitive cycle of 4 weeks frost protection 1 week normal etc. I guess part of an home automation system would do it or you could use a PLC.

Good points. Every time I go to set the holiday time on my own system, though, the thought strikes me: I am actually advertising to any potential and clueful burglars just how long the house is likely to be unoccupied ?

What with that and the massive thermal inertia in my house, I often just leave it on, especially if it's just a long weekend.

Personally I think pressing the holiday button 21 times is the easiest but... Say really want to go the whole hog and have a fully programmable heating system you could change your current heating controls to the Honeywell smartfit system, then connect these via this interface

My house heats up in 1 hour when I get back from holiday, so I don't really see this as a problem.

You want a telephone operated one then

Ok, that would make sense and provide me with a way to achieve this. I've had a look at a few models, but can't seem to find one with a "holiday" setting, can anyone recommend a model.

Thanks

Seven day 2 channel models such as: Horstmann Channelplus XL H27 Drayton (Invensys) Tempus 7

If your existing programmer is on a backk plate it should be a simple case of removing a grub screw and latching the new one in place.

Ours takes 3+ days to stabilise if we let it get cold, lots of thick stone walls just suck the warmth out of the air.

I have a Danfoss TP75(*) which has a "holiday" setting. Fairly sure that the other popular one, the Honeywell CM67 has it as well. The smaller programable stats seem to only have a frost protection which is manual on/off rather than reverting to the programed mode after n days.

(*) To be replaced by the TP7000 according to

In which case, why do you need something to switch the heating on in advance of your return at all ? Come in, fire it up, pop out for a Chinese, and by the time you get back the house will be warm...

I don't. The OP wanted a solution. These things all look good on paper, but at the end of the day the simple solution (keep coat on, get neighbour to switch it on for you etc.) win for me every time

If you go to the Maplin web site and then search for product code N34BF you'll get a remote control board which will work with a mobile phone - cost is £14.99.

Something like this any good ?

Or even this : (just a bit of fun on this one)

Oops, sorry. Misread Toby as Tony.

That's excellent, thanks

How does it work (i.e. put it together), there doesn't seem to be any information on the site. How do you access it through your mobile. I definitly want one of these if someone can explain how I can make it work.

Thanks
