RE: Automating a thermostat

["Ian B" <Ian@xxxxxxx>]

I have done exactly this with a TX15B replacing a normal mains voltage
mechanical thermostat. I mounted the black box of the thermostat under the
stairs and out of sight. This is connected to the replacement thermostat
which is mounted where the original was. This now just left actually
switching the mains voltage to the heating system. I made a little
veroboard
unit which has a mains rated relay being switched by 12 volts which in turn
is switched by the relays on the TX15B.

I actually have my central heating on all the time day and night, summer
and
winter. Heat is now controlled entirely by HV and the TX15B. Wifey loves it
as she can now turn on the heating from bed with a remote control.

I am happy to provide photos and whatever help I can if you go down this
route. It was not a bad job and all I needed was a mains test screwdriver,
multimeter for 12 volt detection and drill etc. for mounting.

Thanks for the link - does not look like an easy job at all.  Has anyone
installed on of these in their house in a retrofit application?

Also, the warning says:"Note: The thermostat contains 3 low voltage
relays
that are NOT suitable for switching 240V mains power. If your boiler
requires a thermostat capable of switching high voltages you will need to
add external relays. This is NOT an easy DIY job !"

Is there an easy way to tell if my boiler requires a thermostat that can
switch mains power?
