The CC25 and CTC20 servomotors integrate the regulation logic and the devices necessary to manage the mixed circuit without needing additional components.
CTC20 makes fixed point regulation possible (in heating and cooling) and has an outlet for the secondary circulation pump.
CC25 is an actual climatic regulator for heating/cooling complete with external probe, secondary pump outlet and touch-screen display for programming. It can also connect several servomotors via bus which share external temperature information during regulation.
Both devices can be applied to traditional sector valves (3-way or 4-way) and to the mixing units of the VARIMIX system.
