Doctor D - I am trying to replace a Drayton RTS1 with a Horstmann DRT2. The Drayton has 4 cables going to it, a neutral, a live, an earth & a call for heat - which I presume is the thermostat switch. The Horstmann only shows 2 connections to be used, the NO & the COM with the neutral going straight to the heater - help please. Where do I put the neutral & does the live just go to the COM with the 'call for heat' cable going to the NO??
