Hi,
i just bought a new Horstmann c17 programmer, which I tried to install but doesn't seem to be working correctly. My original set up was a combi boiler with a room thermostat connected by a Live/neutral flex (earth wasn't connected).
the terminals on the c17 programmer are N L 1 2 3 4.
When i installed the c17, I split the wire to the thermostat and fed the wire from the boiler to the programmer, Live wire to L terminal and Neutral wire to N terminal. With the wire from the thermostat I connected Live to terminal 4 and Neutral to terminal N on the programmer. I also wired L to terminal 2 on the programmer. I didn't touch anything on the boiler.
The programmer is working although only once I connected L and terminal 2, but I can set it and the system light is on. However the thermostat isn't kicking in when I set the temperature to high and the boiler is off. Not sure what the problem is.
Any help would be gratefully apppreciated.
many thanks,
Nick Maskell
