Typical Actuators: MP-361, MP-371, MP-381, MP-382, and MP-2113-500.
Typical Barber-Colman Microtherm Controllers: PP-22x Series, TP-2xx
Series, TP-3xx Series, TP-4xx Series, and TP-101x Series.
C =Common of Switch to R and B.
1 =Feedback from actuator (24 Vac with actuator full Counterclockwise rotation (CCW) to
12 Vac at Clockwise rotation (CW) end).
R =Closes on temperature (pressure) drop and drives the actuator CCW (opens valve).
B =Closes on temperature (pressure) rise and drives the actuator CW (closes valve).
Typical Cooling Barber-Colman Microtherm: TP-1031.
