Review on πŸ”€ Efficiently Control Zones with the SR501-4 Switching Relay by Dwight Tim

Revainrating 4 out of 5

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
