Series CRB100 is an indoor based controller with integrated actuator for use on mixing valves like VRG130 and VRB140. The controller is designed to provide a high level of comfort and at the same time provide energy savings for the house owner. The regulation is based on indoor sensor feedback and is changed by altering the target temperature in the room display unit. The actuator unit can be connected to the room display unit either by wireless radio connection (CRB120) for easy installation or by cable (CRB110). With the inbuilt timer, with day and week program, there are possibilities to have day and night settings with an alternative temperature for even further energy savings.
