ESBE CRK210 Controller User Guide

ESBE CRK210 Controller

ESBE Series CRK210 are combined actuators with controllers. The CRK210 range offers constant flow temperature control for devices with combined heating & cooling function. The Series CRK210 is intended to be used with valves Series VRx.

Operation

• The CRK210 is a constant temperature controller intended for applications where a constant flow temperature is desired. The controller is integrated with an actuator and is designed to be used with rotating mixing valves series VRx.
• The Series CRK210 consists of two main components: an actuator and a flow temperature sensor. The primary function of the controller is to maintain a constant set temperature at the sensor location. The series includes a T/T2 (main temperature to alternative temperature) setting, which also controls the opening direction of the actuator. This feature is intended for devices with combined heating and cooling functions set by relay. Additional equipment, such as a clock, may be needed to release the relay if the heating/cooling unit lacks an available control signal. Releasing the relay changes the actuator’s working direction to match the source unit’s mode (heating or cooling). Settings are adjusted via a joystick and displayed on a screen.

Introduction of ESBE Self-Adaptive System

The ESBE Self-Adaptive System manages PI factors (Proportional gain and Integral response) by learning system behaviors and addressing issues previously managed by installers. This system ensures smooth controller operation, eliminates issues related to delays or response times, and delivers high control standards and comfort. This makes the CRK210 Series suitable for any system setup or environment.

INSTALLATION

• Power supply by 230 V AC adapter (complete with transformer, cable and wall socket plug).
• Flow temperature sensor comes with 1,5m cable included (longer cable available as accessory). The sensor must be carefully insulated from ambient temperature.
• Thanks to the special interface between the controller series CRK210 and the ESBE series VRG and VRH, the unit as a whole has a unique stability and precision when regulating.

INSTALLATION EXAMPLE

Constant flow temperature going to the heating circuit
The CRK210 controls and secures the set flow temperature. The controller is connected to the device with combined heating and cooling function. The connection is done via relay, which when released will change the opening direction of the CRK210. This feature allows the CRK210 to adjust the work principle between heating or cooling working mode of the heating/cooling device.
