Hi wizard, first thanks for the intrest
The diagram im working from is attached. The system is on the other side of scotland from me so im trying to understand the detail before i go and look at it. The problem with the system is a limited supply of hot water, could be heaters or thermostats but could also be the control system relays (top middle of diagram). I am trying to get the owner (relatives) to identify the relays and timer details at the moment. The system is described in the churchillsystems web site,sort of
Relays are somthing im not familiar with
