Hello,

I am in the process of replacing the danfoss with the towerstat thermostat.

The towerstat instructions refer to 2 wires to connect but my danfoss has 3 wires coming into it. - grey with blue sheath (neutral?), brown (live?) & black with brown sheath (live?).

My boiler is a Glowworm Ultimate (1 year old) if this sheds any light.

Could someone advise which wires go where please?

Many thanks,

Chris
