Overview:
The Mixing Setpoint Control 153 is a microprocessor-based control with a floating action output intended to operate an actuating motor for a valve or damper. The 153 can be used for heating applications to maintain a set supply water or air temperature. An optional return sensor can be used to ensure a minimum boiler return temperature. An adjustable throttling range and setpoint temperature allows this control to be used in a wide variety of applications.
