GENERAL INFORMATION
1.1
USES
The Pro2 circulating pumps are used for the transfer of liquid medium within systems for hot-water heating,
air-conditioning and ventilation. They are designed as single or twin variable-speed pumping aggregates where
the speed is regulated by electronic device. The pump constantly measures pressure and flow and adjusts the
speed according to the set pump mode.
The pumps have the option of remote control and monitoring using Ethernet, Modbus, analog inputs and
outputs, and relay control. See communication installation for more information.
The main purpose of the twin pump is uninterrupted operation if one of the pumps fails. Common hydraulic
housing is equipped with a change-over flap and two pump heads, separately connected to the electrical grid.
