Review on π Efficiently Control Zones with the SR501-4 Switching Relay by Dwight Tim
Used to add an extra zone
I already had a Taco 6 zone relay that was being used to full capacity so I bought this unit to add an extra heating zone. The element is easy to connect and works well. My only complaint is that it makes a slight hum that can be heard in the room above my boiler.
Pros
- Weight
Cons
- Reliability
