The One Stage Setpoint Control 150 is designed to operate a single
component of a heating or cooling system in order to maintain a set
temperature. It can be used in applications ranging from heating a
swimming pool to maintaining a constant slab temperature in a commercial
car wash bay. This control regulates a constant setpoint water
temperature for heating or cooling. The 150 is designed to operate a
single relay (rated at 240 V, 8 A) to control a single device such as a
boiler, pump, or valve.
