A flow switch relay helps interpret or manage the signal from the flow-monitoring side of the heater system, and this Coates Q-12DS relay is designed for compatible 240 volt applications where the original relay has failed or become unreliable. When the relay tied to flow protection begins to fail, heater operation can lose an important part of its control logic.
The Q-12DS format and 240 volt relationship give this part practical value because control relays work best when they match the original heater circuit requirements closely. A properly selected replacement helps restore intended signal-handling support for the flow switch system and contributes to cleaner heater operation.
This type of replacement is especially useful when the main flow switch and surrounding circuitry remain serviceable and the weakness is centered on the relay itself. That keeps the repair focused and efficient.
Installed in the proper setup, this relay helps restore dependable flow-related control support and contributes to a safer heater repair overall.
- Flow switch relay for compatible Coates heater applications
