Hi there,

We have recently replaced our central heating programmer with a Honeywell ST9400C. We now want to replace our old wireless room thermostat with a compatible one. We've purchased Honeywell DT92E (with receiver and controller). Next to the boiler, underneath the programmer, is an existing wireless receiver (Danfloss). This is what we will replace.

The backplate for the old receiver is below.


Here's the wiring diagram on the back of the old receiver:


The new Honeywell DT92E receiver has a different backplate that needs to be wired in. It has a different setup - N, L, L, A, B, C.


Does anyone know if our existing wiring is compatible, and if so, which of the existing wires go in which slots?

Many thanks!
