providing a dedicated power source for the actuator without straining existing furnace or air handler control boards

Extended Temperature Range: Reliable performance from -40°F to 122°F for diverse mechanical and outdoor environments

Replacing a failed furnace heat exchanger restores system pressure and prevents the rollout or inducer limit trips common in older 90% plus AFUE models

Its 3P configuration provides full break control for three-phase compressors and motors

Can I use this switch for both heating and cooling fan applications

Belimo EFB24-SR Actuator R-407C providing a dedicated power sourceThe Belimo EFB24 SR is a high torque, spring return damper actuator engineered for modulating control in demanding commercial HVAC systems. Delivering a minimum of 270 in lb torque, this proportional actuator is designed to operate large air dampers or actuated valves with precision. It operates on a 24VAC DC power supply and accepts a 2 10VDC control signal, which can be adapted for 4 20mA applications using an external 500 resistor. Featuring a
