Two Stage Setpoint Control

OverviewThe Two Stage Setpoint Control 152 is a microprocessor-based control that operates as either a two stage setpoint control or as two independent setpoint controls. As a two stage setpoint control, the 152 can provide two stage heating, two stage cooling or a combined heating / cooling interlock function. When operating as two independent setpoint controls, the 152 can control any combination of heating or cooling device.
