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 congurations.
The CRA112 can also be mounted to ESBE’s
discontinued MG and G series valves up to 2”
size.
Benets:
• 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.
