FAQ
Why manual reset instead of automatic reset?
Safety standards for commercial heating equipment generally require that an over-temperature event cannot clear itself. Manual reset guarantees a service check happens before restart.
Can the trip temperature be set to my requirement?
Yes — trip points are factory-calibrated to your specification. Tell us the equipment's normal operating range and the required cut-out temperature.
Do safety limiters replace the control thermostat?
No. A control thermostat regulates day-to-day temperature; a safety limiter is independent backup protection. Equipment should have both.
