temperature by either mixing or diverting.
The compact CRA112 control mounts directly
to an ESBE VRG valve body ( ½” to 2” only)

- both 3-way and 4-way congurations.
The CRA112 can also be mounted to ESBE’s
discontinued MG and G series valves up to 2”
size.

Benets:

• Complete control package; actuator
The ESBE CRA112 is a combined actuator and
constant ow temperature control with an
adjustable setting operation range. This constant
regulation of ow temperature is an ideal
controller for applications that require constant
monitoring or regulation of temperature. Several
application examples could involve domestic
hot water, slab radiant heating, or return water
temperature protection. Depending on the
placement of the sensor and the piping of the
CRA112 assembly, it will either be regulating the

Applications:

3-Way Mixing/Diverting Application

System

The CRA112 can be utilized to maintain a set water temperature for a mixing or diverting
application. Via the remote sensor the controller maintains the temperature by regulating the
appropriate supply water temperature to the system.

4-Way Mixing Application

System

The installation of the CRA112 on a 4-way valve
will adjust the valve to provide the appropriate
temperature of supply water to the system.

Indirect Hot Water Heater

The utilization of the CRA112 on an indirect hot
water will help in maintaining appropriate tank
temperature at both a minimum and maximum
setting thus providing a consistent temperature
within the indirect.

Radiant Heating Application

In radiant heating applications, the CRA112 is
ideal in maintaining a consistent temperature
requirement. The sensor can either maintain
the required supply water temperature to
the system or potentially maintain a surface
temperature based upon the sensor’s location.

Air Sensing Fan Coil Application

If there is a necessity to maintain a particular
consistent air temperature across a fan coil, the
CRA112 can assist in maintaining the necessary
temperature.

Electrical Wiring:

External Relay, T2:

Included with the CRA 112 is a wire lead with a plug. The plug side is
inserted directly into the control actuator while the other end of the
lead is connected to a 24VAC power source.

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 gives priority to the T2 temperature set­ting and overrides the primary setting. This external relay can be utilized as a setback or boosting of
the setpoint temperature based upon the application requirements.

Mounting &
Installation:

The actuator should be mounted with the ESBE rotary valve stem in either a horizontal position or
pointing upwards. The actuator should not be installed in a downward orientation to reduce the
possible contact with water. Included with the actuator is the mounting hardware necessary to
mount the actuator to an ESBE rotary valve, i.e. VRG or the discontinued MG & G series.

Mounting &
Installation Contd.:

Manual Operation:

The orientation of the drive sleeve determines the version of valve the actuator will mount to.

Orientation Mounting Drive Sleeve

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 to the actuator.

To manually operate the CRA actuator, partially pull out the large indicator knob (1). With it partially
out, rotate the knob to the left or right to manually operate the valve (2). To return the actuator to
automatic operation, rotate the knob to the position prior to manual operation and push the knob
back into the original position.
