It monitors the discharge air temperature in a duct and sends a signal to the modulation control to adjust the gas flow to the burner

Versatile Power Compatibility: Operates seamlessly on both 24Vac and 24Vdc

Using it with ammonia will degrade the pressure element and internal seals

Common Questions Can this valve be used in 120V systems

Warrick 26MB1A0F Control Refrigerant It monitors the discharge airThe Warrick 26MB1A0F Control is a professional grade liquid level control engineered for low water cutoff (LWCO) protection in industrial boiler and HVACR systems. Operating on a 120V AC supply voltage, this unit features a 10K ohm sensitivity range, making it ideal for standard water based applications where precise conductivity sensing is required. The solid state liquid level control is designed as an open circuit board for plug in installation via
