I purchased a Honeywell DT92 wireless thermostat. replacing a standard analogue theremostat. I have only 2 wires.
Relay box shows NLL ABC
where do my 2 wires go.
Do you have another 2 wires for the L N? If so then depending on your boiler some boilers have a live out switch live in. As live out would go to A and switched live back to your boiler from B. another way is a loop so aslong as its in A/B. and some just have a live in.
