Adding room thermostat to combi boiler
I have a glowworm swiftflow 75 combi boiler, which currently has no room thermostat, just an electromechanical timer built into the front panel of the
boiler.
I want to add a room stat to the system, prob a wireless one to make things a tad easier. Presumably I just wire the "boiler end" of the
wireless stat setup so that its switching output is in series with the existing timer unit on the boiler, or remove the timer, replace with the new
unit and use the timer built into it?
I kinda know the answer to my own question but wanted to know from somebody that's done it!
cheers

There will be a wired link across the roomstat wires in the boiler, which basically bypasses it. You need to remove the link and wire the stat across
the terminals. Eg the live terminal to feed the stat and the return from the stat to the other teminal. If the stat needs a neutral there will also be
one in the boiler

ah ok, well that would be easy! Its a pretty basic boiler so I wasn't sure if it would have been designed for a stat!
will order one and have a look once I have it
cheers

Yup. Exacta mundi. If there's a timer switch you'll need to wire it in series to the timer.

Most new thermostats with have options for older and newer boilers, usually high or low voltage switching. Either way it should be just a case of re
wiring for the existing timer.
I bought one of these and works great. Has a 5 + 2 day timer and 5 different programs for each day. Also has a freeze protection button so if you go
away on holiday it turns off the heating but makes sure it doesnt drop below 5c. Also as it has a timer it means you can get rid of the one on the
boiler and it will set the temperature depending on the time of day.
