Flomasta thermostat upgrade

1999JM · 31 Oct 2023

Good evening all!

I'm about to upgrade my existing thermostat in my home and was wondering if I could have some advice..

.

this is the current wiring with the diagram. I believe I will need to add a link from the red wire to the common and then move the yellow wire to the no 1 wire in the terminals below. Just need a bit of reassurance as I don't want to damage my boiler.

Cheers !
