A bypass line (field supply) needs to be installed which guarantees that at all times the minimum water flow of

the unit is supplied (refer to the “Operating limit” chapter for indication on minimum water flow). The bypass

valve will be an ON/OFF normally closed valve controlled by the unit. In case the minimum water flow allowed is

not reached, the unit will open the bypass line restoring the water flow above the minimum value.

strategy. In case of multiple units installations in a primary only plant, to control the pump speed iCM is required.

Master/Slave function does not support primary only chilled water systems with variable flow operation.

The inverter kit can be used for the following purposes:

- Adjusting the water flow rate during unit commissioning.

- Control the pump speed via external input from Building Management System (BMS)

For this application a 0-10V signal for the pump speed must be provided from the plant manager according to

the specific control strategy of the plant. The water must be within the minimum and maximum value allowed
