Description
The Honeywell TP971B2019 Pneumatic Thermostat Reverse Acting Heating Day/Night Setpoint 60-90°F is used to regulate the temperature in HVAC systems by converting the measured air temperature into electrical signal. It changes day and night setpoint and generates 16 PSI in the day and 21 PSI at night to operate heating valves or dampers. The thermostat is installed in mechanical rooms or control panels and is connected to the actuators of the pneumatic air supply and system. It is used to provide accurate zoned heating control and monitors the operation of a mechanical system.
