Technical Specifications
CRA112 Setpoint Control
The ESBE CRA112 is a combined motorized actuator and constant flow temperature control with an adjustable setting operation range. Ideal for applications that require constant monitoring or regulation of temperature such as 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 be regulating the temperature by either mixing or diverting. The compact CRA112 control mounts directly to an ESBE VRG valve body (½” to 2” only). The CRA112 can also be mounted to ESBE’s discontinued MG and G series valves up to 2” size.

CRA122 Setpoint Control
The ESBE CRA122 is a combined motorized actuator and constant flow 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 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 90 Series mounting kit code no. 193B1616.

- Power Consumption: 3VA
- Rotation: 90° (factory), adjustable from 30° to 180°
- Torque: 135 in. lbs (15Nm)
- Mountable ESBE Valve Styles Sizes: MG & G Series (discontinued), F Series, VRG Series (requires mounting kit: 193B1616)
- Enclosure Rating (actuator & control): NEMA 13, IP54
- Ambient Temperature Range: 23° to 131°F (-5° to 55°C)
- Run Time: 120sec (default) Selectable: @60Hz: 12/25/50/100/200/398 seconds, @50 Hz: 15/30/60/120/240/480 seconds
