Johnson Controls T-4003-203 Thermostat Refrigerant UDAS units utilize a separated

UDAS units utilize a separated combustion design that requires different pressure switch settings and orifice configurations

Mechanical Protection: Brass friction washers minimize friction during assembly

ensuring the system operates within its designed subcooling and superheat parameters

The 47-20545-91 utilizes a sensitive bimetallic probe to monitor localized air temperature

this assembly ensures the motor remains perfectly centered

Johnson Controls T-4003-203 Thermostat Refrigerant UDAS units utilize a separatedThe Johnson Controls T 4003 203 is a high volume output submaster pneumatic thermostat engineered for precise proportional control in complex HVAC systems. Designed for reverse acting operation, this unit utilizes horizontal mounting and is specifically calibrated for applications where a remote master controller resets the setpoint based on external variables like outdoor air temperature. With a massive 400 SCIM flow capacity and a low 20 SCIM air
