I am updating my one zone water heating system to 3 zones. A SR504-exp-4 Switching Relay will be added to control these zones.
I found a sample wiring diagram from the Alpine installation guide. My switching relay is not the same as the one on that diagram. AND there is NO DHW in my case. We use a separated electrical hot water tank instead. So I made a diagram for myself with my switching relay. The red lines are added by me. The blue lines are corrections suggested by other people. Are these red lines and blue lines correct?
Please help me to make it right.
