setting the central heating for winter

[Soir]

Had new Central Heating (worcester combi) installed with a remote thermo/programmer

I want to have a min temp of say 18-19 degrees to come at certain times in the day (such as early morning couple hours then late afternoon for the rest of the evening)

Then in the night, rather than totally off - want to set a min temp of say 12 degrees (so house isn't freezing)

is there any way to have two seperate temperatures set? (without doing it manually. Because if you set manually before bed at 15, then it will remain at 15 when it comes on again early morning..when you want it to be 18-19)

Does this make sense? Bored me just typing it (apologies as I just cannot get my head around it)

[Kermit power]

Would something like this do the job? Seems to drop the temperature by 4 degrees rather than completely switching off?

Do you have a separate room thermostat? I replaced the basic temperature control one in my hallway with a Danfoss TP5 programmable one. The CH is on 24/7 but the Danfoss regulates the temp in the house. You can set diferent temps for different times of the day. I've not checked, but I think you can have 6 or it may be 8 different temperatures over the course of 24 hours.

yep, you want a programmable control unit - Can't tell you if they work or not as my wifes idea of central heating is leaving it on 24/7/365...

[Soir]

I think its this one we have

it is a wireless programmer, but I don't think you can have different temps at different times?

We've had a new Worcester Combi installed and I got one of these - does exactly what you want it to do.

Ive just had a Worcester combi fitted and it came with a remote thermostat with 2 setting comfort and economy. You set comfort for the times your about the house and economy for the rest we have 18c for comfort and 10c for economy which is between 10pm and 6am. It is a Worcester thermostat.

[RonJohnson]

As per Living the Dream said - we've just had the same thermostat fitted and it works brilliantly - 6 different time zones - complicated enough for anyone.

I have one of these.

Frost protection could be turned up to your required night time setting. Top peice of kit for not a lot of money

Was going to recommend this. Very simple to use.

If you want something with a few more features, the Honeywell CM927 is probably the best programmable thermostat available.

The CM927 would be (and was) my choice, excellent piece of kit. 6 temp changes per day (effectively on\off depending what you set them to)

Party mode setting worthwhile alone
Copy day function useful for bulk changes

Moved house now but looking to fit to the new place if I can find a cheap seller again

I got a CM927 after seeing it recommended on practically every forum, it does everything I want. One nice feature is holiday mode, where you can set it to stay at a low temperature for a certain number of days, then resume back to normal.

The only thing it doesn't do is hot water, however that obviously just needs on/off at certain times so I just left the old timer in place with just the hot water circuit connected.

Another vote for Honeywell CM927 - I have the wireless one. Set it up and forget about it!

I have it set to 20 in the morning and again in the evening, 18 through the day, and 16 at night to keep the chill off.

6 a day, for both heating and hot water. You set the times you want the temp in the house, it has internal and external sensors, so the actual turn on and off times vary to keep the house at the temp required.

Which one has external sensors?


Does the CM927 directly replace your average wall-mounted thermostat ? Will the relay box mount directly onto a single pattress and use the same wiring for a modern combi? I'm in a rented property, so major changes are out.

Won't fit on a standard single pattress, but is about the same time. Screw it to the wall, swap over the 2 or 3 wires, and bob's your uncle.

Wireless one has a sender that screws to the wall, and you can put the sender anywhere.

Brilliant.

So do these replace the thermostats that have the 10-30oC twist dial?

We have a Baxi combi at our new place, which has a 'Summer' and 'Winter' setting, and then a wheel with 24 hours of the day on and pins you push in and out to say whether it should be on at that time or not...

Never paid much attention to how central heating works so we usually keep the twist dial at 10oC and then turn it up when we want the heating on, and twist it back to 10 to shut it down... I take it this will Not Be Good when it comes to getting really cold overnight?

Effectively it will replace the timer and the twisty dial stat. The beauty of them is that you can set the temperature for different times of the day. The CM927 is also a frost stat, has a holiday mode, party mode and during the summer I used it as a clock and thermometer as it has a nice big clear display!

I try to maximise effeciency in my house by shutting all the doors, turning the TRVs on the rads down low on the rooms not in use and having the thermostat in the room I'm using.

Just remember to turn the TRV all the way up in the room where the stat is located, otherwise the TRV could turn the rad off before the stat can reach temperature, meaning the boiler will continue to fire and waste fuel!

I'm pretty sure the reciever unit will screw onto a single gang electrical box as does the backplate for the thermostat unit.

What's party mode? Sounds rude
