hi,
I am trying to replace my old Thermostat acl Drayton with a Horstmann DRT" but there are 4 wires in the old thermostat and I am not sure which to use.
Inside the Drayton it says T45, and there are 3 wires connected - Blue to N, Red to L and Yellow to 3 (call), now the drt2 has 3 connections com, nc and no, any idea which wire goes in which connection?
many thanks
