Description
The Johnson Controls T-4506-217 is a pneumatic thermostat that is used for accurate control of temperature in commercial and industrial premises. Unlike electronic thermostats, it employs compressed air pressure to indicate a damper or valve to modulate the heating or cooling. This has two set points, which means that it can have different temperatures during the occupied and unoccupied time. This can also assist in conserving energy and ensuring that the appropriate temperatures are maintained throughout the day. It is powered by a 24VAC signal and can be used in on/off applications and in proportional control.
