How to Connect Honeywell T6360 room thermostat to combi boiler Worcester R 40, more? Sorry to say you can not. The T6360 is a single voltage network on / off thermostat, terminal 1 live, work and live more neutral terminals. The Worcester boiler must be controlled by an electronic sensor operating temperature range, additional TR2 low voltage trend with terminals 3.4 and F correspond to the reference terminal of the boiler. That is why you can not find a wiring diagram for a standard room thermostat on the instructions of Worcester. The TR2 unit has several advantages over a thermostat providing protection against frost, optimization and temperature displayed on the display panel of the boiler. This is worth the extra cost for the optimization feature alone. The sensor is very easy to wire if it is done in strict accordance with the instructions Worcester.
Hope the above is useful.
I would contact a local electrician who has experience with boilers.
