KMC Controls HFO-0027 Strip Ensure proper 24V transformer sizingThe KMC Controls HFO 0027 is a precision engineered thermostat setpoint stop strip designed specifically for limiting the adjustment range of pneumatic thermostats. As a critical HVAC control accessory, this strip allows technicians to establish physical high and low mechanical limits within the slider track of the controller. By installing the HFO 0027 setpoint limit, you effectively prevent unauthorized tampering and ensure that temperature setpoint
