Check that the pressure differential across the valve meets the 1 PSI threshold and ensure the solenoid coil voltage matches the power supply

The valve features a manual adjustment spindle

a crankcase heater is highly recommended to prevent liquid migration during the off-cycle

Can I substitute an auto-reset switch for this manual reset model

Carrier HH18SA100 Temp Act 320788-704 Check that the pressure differentialThe Carrier HH18SA100 Temperature Actuator is a critical OEM replacement component engineered for integrated climate control within commercial and industrial HVAC systems. Designed for precision temperature regulation, this switch style actuator functions as a dedicated thermal gatekeeper, cycling heating or cooling stages based on real time feedback from high sensitivity thermal sensors to maintain tight setpoint tolerances.
