Description

The TP972A Thermostat is single temperature, Direct/Reverse Acting, Heating/Cooling, Summer/Winter for pneumatic heating and air conditioning systems.

The standard TP972A is RA for cooling and DA for heating. A rise in temperature at the TP972A with main air pressure at 13 psi causes the TP972A to lower BLP, opening the valve to control the temperature with chilled water. A fall in temperature at the TP972A with main air pressure at 18 psi causes the TP972A to lower BLP, opening the valve to control the temperature with hot water. Models are available that limit the cooling setpoint and heating setpoint. They work with 13/18, 16/21, 19/14, or 20/25 psi changeover. Some models are DA for both cooling and heating.

The TP972A2143 is designed to replace Johnson Summer Winter thermostats. New and recycled covers are available.
