Electrical Wiring:
3-Way Diverting Application
When the CRA122 is assembled on a 3-way
valve installed in a diverting application, the
controller can monitor return water temperature
and adjust the valve appropriately.
4-Way Mixing Application
The installation of the CRA122 on a 4-way valve
will rotate the valve to provide the appropriate
temperature of supply water into the system
side.
Supply Voltage 24 ± 10% VAC, 50/60 Hz
Power Consumption 3VA
Rotation 90° (factory), adjustable from 30° to 180°
Torque 135 in. lbs (15Nm)
Mountable ESBE Valve Styles Sizes MG & G series, F series, VRG w/ mounting kit
Enclosure rating (Actuator & Control) NEMA 13, IP54
Ambient Temperature Range 23° to 131°F (-5° to 55°C)
Adjustable setpoint temperature range 41° to 203°F (5° to 95°C)
Weight 1.9lb (0.9kg)
Run Time
120sec (default), Selectable:
@60Hz: 12/25/50/100/200/398 seconds
@50 Hz: 15/30/60/120/240/480 seconds
The actuator should be mounted with the valve stem in either a horizontal position or pointing
upwards. The actuator should not be installed in a downward orientation.

ing hardware
7) Mounting Base
10) Mounting Stud
When installing the handle, it should be installed opposite to the indicator on the drive sleeve and
the end of the handle should be facing away from the valve. Failure to properly install the handle
will result in damage to the 90 series motor actuator due to the interference of the mounting stud
with the rotation of the handle
Installation:
External Relay, T2:
Incorrect handle
orientation
Correct handle
orientation
An external relay connected to the T2 terminals on the CRA signals the control to maintain a dierent
setpoint temperature. When the relay is closed the control looks to the T2 temperature setting and
overrides the current setting. This external relay can be utilized as a setback or boosting of the set-
point temperature based upon the application requirements.
