OT : Heating Programmer Experts Wanted
SeaBass - 4/11/09 at 04:18 PM

I'm fed up with looking into a dark cupboard to see a tiny LCD programmer that I can't read so I was thinking about changing it.

I thought it might be good to change it to wireless and mount the transmitter on the kitchen wall about five meters away as a room stat.

I was looking at Honeywell and Siemens units but have a problem: I can't find a 7 day wireless programmer/stat which will control both my boiler and the (one) motorised valve for the hot water ie a 2 channel unit.

Anyone had this issue?

dont think you can get a 2 channel wireless stat

I replaced my thermostat with a programmable one which has time and temperature settings for each day, I just leave my controller permenantly on now and let the programable thermostat do the job simple to fit and its now located on the wall in the hall.

This will achieve the same thing see screw fix

Big Vee, sounds great but I need mine to control the hot water too the one in your link is only for the heating and it's not wireless.

Out of interest though how did you manage to install a wired unit in the hall away from the boiler?

what you would normally do is to leave exisisting programmer to control DHW alone. Then purchase a RF programable room stat for your heating,

How do you wire it so that both units are able to switch on the boiler then?

Not sure my OCD would cope with that solution either.

I'm using nice Salus units with fancy blue backlights. They do a HW/CH unit and it's 7 day programmable.

I'm using two of their single channel programmable thermostats for the underfloor heating and main heating in my new house.

It's not RF but hey....


adam1985 - 4/11/09 at 07:09 PM

salus do rf stats and progs but none are 2 channel

Hi Again, you leave the Heating side of the controller permanently switched on-you leave the Hot water side as it was -switching on and off.

You replace your existing wall mounted thermostat with the one I linked to, connecting the existing thermostat wires to it.

You program the thermostat Sunday through to Saturday with 6 time programs and temperatures through the day.

Your heating controller is then on a wall where your thermostat used to be takes about 30 mins to do.

The programmable thermostat turns the boiler heating mode on off through the day.

Quite a bit as the Winter draws in to cut my energy bills.

I also wanted to add the thermostat functionality which we don't have. It just churns out heat at a specified boiler temperature for a set amount of time. This costs extra money!
