Heat pump acquirer
State / alarm acquisition and control for heat pumps
Control unit for cumulative alarm acquisition, also on/off and mode change (heating/cooling) commands to heat pumps.
It also allows the acquisition of delivery and return temperatures to the users.
Up to 2 heat pumps can be managed for each control unit.
Available in stand-alone version or on electrical box equipped with electrical protections and decoupling relays.
Temperature acquisition FROM and TO UTILITIES generated by heat pumps, using NTC type transducers
