We have fitted, a Heatline Monza 24KW condensing combi boiler. It has 24v and 240v connectors, although I'm lead to believe the 24v is just for the boilers built in controls.
The programmable thermostat is a Homexpert(Honeywell) THR870CUK, 7 day program, two wire, 'VOLT FREE' jobbie, that requires two AA batteries. It can be wired to 24v or 240v.
On the boiler there is a loop connector on the 24v 'RT' side which I have removed. On the 240v side there is a 'L' 'N' & 'E' for the mains, and on the same block 'RT' room thermostat and 'FP' frost protection.
The 'VOLT FREE' stat has two sets of terminals. First block has 'A' 'B' & 'C', the second block has '1' '2' '3' & '4'.
My question is this; where do I wire the 'VOLT FREE' stat? I'm begining to wonder wether I can only wire a mains volt stat to this boiler??
I'm guessing if it's possible I would wire it up as per 'BASIC BOILER' on the Homexpert manual, and wire 'A' from the stat to the 'RT' terminal on the boiler, and 'B' on the stat to the 'LIVE' on the boiler?
I can't post the links to the manuals, but they are easily found on google.
Many thanks in advance for your help, as I'm at a loss.
