Trane MOD1301 Actuator Freon The Johnson Controls T-4752-205 is

The Johnson Controls T-4752-205 is a high-performance pneumatic heating-cooling thermostat engineered for precise proportional control in commercial HVAC systems

you can safely upgrade to a higher FLA rating (40A) as long as the coil voltage (208/240V) and the number of poles (3-pole) match the original specifications

Technicians should verify that the probe voltage and current specifications align with existing level sensor electrodes to maintain optimal electrolytic balance and prevent electrode fouling during long-term operation

Key Benefits Steam-Specific Seals: Utilizes EPT (ethylene propylene) internals to maintain seal integrity in temperatures up to 300°F

Trane MOD1301 Actuator Freon The Johnson Controls T-4752-205 isThe Trane MOD1301 Actuator is a direct OEM foot mount actuator designed for high precision HVAC damper control. This 2 10VDC modulated unit operates as an electrical to mechanical transducer, translating low voltage signals into accurate positioning for dampers or valves in residential and commercial air handlers. A key field feature is the spring return mechanism (S R), which ensures a fail safe position during a total power loss, protecting the coil
