Hi Everyone, I'm new here and dealing with a very bespoke system so please be gentle.
Basically there are two zones in the house. Upstairs (with hot water) and downstairs.
Originally the zones were controlled by two Horstmann H17 XL with separate thermostats in each zone.
So far I have done the following:
Installed one single channel hive on the downstairs zone (just heating).
Installed one dual channel hive on the upstairs zone with hot water.
At the moment I have just bridged the old thermostats as the connections in the wiring box are just too complicated for me to bridge in the box and I needed a quick solution as the heating has not been working.
The issue am I am facing is that the boiler simply doesn't turn on, it is a pellet system, however I have managed to get it working but it switches off and says "stopped by external contact". The pumps all work and the system appears to be working, just without the boiler.
I've attached images of the wiring in the main panel and have followed the normal installation for the Hives.
If someone could look and give me a steer as to where this is all going wrong I would appreciate it.
If I have missed anything just shout and I'll post more images.
Thanks in advance!!
