Honeywell ST699 thermostat upgrade.. Discussion Thread
I have a fairly old Honeywell ST699 thermostat that controls the central heating and hot water on a Worcester boiler. It is in an old farmhouse which has an airing cupboard with a hot water tank. There is also a separate thermostat located near the top of the stairwell.
I'd like to upgrade it to a wireless thermostat if possible and was wondering if anyone has replaced this model. I have fitted a Nest unit before, however this was on a combi boiler and I'm not sure how straight forward replacing this unit is going to be.
Any advice greatly appreciated.
