Information:

valves in the recommended sizes ranging
from 2-1/2” to 6”. The CRA122 setpoint control
can also be used with smaller sized VRG valve
bodies with the use of the VRG to Series 90
mounting kit code no. 193B1616.

Benets:

•Complete control package; actuator,
sensor* and controller included *Included

sensor is 4.9 ft/1.5m, but optional 16 ft/5 m
cable can be purchased (17053100)

•Simple ‘keypad’ menu and settings

•LCD backlit digital display

The ESBE CRA122 is a combined actuator and
constant ow temperature control with an
adjustable temperature setting. This control is
a direct replacement for the 92K2 control. The
CRA122 monitors and maintains the setpoint of
water or air temperature on mixing or diverting
applications by modulating ESBE 3-way or 4-way

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

Electrical Wiring:

External Relay, T2:

Temperature

Sensor

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 set­point temperature based upon the application requirements.

Installation:

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.

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

Adjustment of
Rotation:

Within the 90 Series actuators, the factory set
90°of rotation can be adjustable between 30°
and 180°. The adjustment of the angle of rota­tion is set via internal cams within the actuator.
Care should be taken to ensure the cams are
engaging the switches properly.

Manual Operation:

When placing the actuator in manual operation
power should be turned o to the actuator. In
the event the actuator is powered and is left in
a manual position, the result could lead to the
internal damage of the actuator.

When placing the 90 Series motor in manual
operation, the gray button must be pushed
in. Then the handle can be rotated either
clockwise or counter clockwise. To return back to
automatic operation, rotate the handle until the
button pops out.
