Boiler Programmer

[homebrewer55]

I have a wall mounted thermostat which is connected to a 26 volt supply from my Glowworm 24ci boiler.
I would like to replace this thermostat with a programmer so i can time when the heating comes on and off.
Currently the heating is turned on/off using the thermostat.
Can the thermostat be replaced with a programmer that works off this 26 volt supply or is a mains supply required.
Any suggestions which programmer i should use.
Thank you

You can uses any thermostat that is 24v rated.
All the thermostat is, is a switch.

So search for any 24v programmable thermostat
