MCE-C is an variable frequency drive with display to be installed in residential building service and commercial building service for the recirculation of water in heating or conditioning systems or on pumps for the circulation of domestic hot water. MCE-C can be set to: constant differential pressure, constant curve, constant curve with external analogue signal and proportional differential pressure. Multiple MCE-Cs can be communicated with each other using a connection cable (supplied separately) in order to be able to create twin groups. The variable frequency drive makes it possible to adapt the performance to the actual requirements of the system and protects the pump from water hammering. It must always be mounted on the fan cover of the motor as it does not have an integrated cooling system. Mounting kit included. Compatible with the DConnect service (DConnect Box supplied separately).
