POWER SUPPLY. PROVIDE DISCONNECT MEANS AND OVERLOAD 
PROTECTION AS REQUIRED.

ACTUATOR SPRING-RETURNS CLOSED WHEN FAN IS NOT RUNNING.

ENSURE THAT TRANSFORMER IS SIZED TO HANDLE THE EXTRA 
LOAD OF THE ECONOMIZER AND ACTUATOR.

1S IS AN ELECTRONIC SWITCH THAT CLOSES WHEN POWERED 
BY A 24 VAC INPUT.

FOR THE ML7295A,C, USE THE 4-20 mA MODEL ACTUATOR. THESE 
MODELS HAVE 500 OHM INPUT IMPEDENCE THAT ALLOWS THE 
ACTUATOR TO ACCEPT A 2-10 VDC SIGNAL.

FACTORY INSTALLED 620 OHM, 1 WATT, 5% RESISTOR SHOULD BE REMOVED 
ONLY WHEN A C7400 ENTHALPY SENSOR IS ADDED TO SR AND + FOR 

DIFFERENTIAL ENTHALPY.

FOR T7300 ONLY.

FOR T7300, USE CONTACTS A1 AND A2 INSTEAD OF THE TIMER.
