CCESSORIES DESCRIPTION
Rubber vibration dampers (KAVG)
To be installed beneath the unit base and the ground to avoid the transmission of vibrations (and the noise) to the building.
Pressure gauges (MAML)
These enable the standing charge and the operating pressures to be monitored.
Electronic soft starter (DSSE)
It is used to reduce the peak current of the unit; the average reduction is 40% of the nominal peak current.
Remote control panel (PCRL)
It allows the remote control of all parameters of the unit.
RS485 serial interface card MODBUS protocol (INSE)
It is used to connect the unit to BMS systems using MODBUS protocol.
Source water 2 way modulating valve (4-20 mA; 0-10 V) (V2MO)
2-way modulating valve is factory installed in the hydraulic circuit at the source side, to optimize the consumption of well water as a
function of the temperature of the available water. The valve is controlled by the microprocessor control unit by modulating
signal 0-10V.
In the event of lack of power supply, the valve is normally closed.
Liquid line solenoid valve (VSLI)
When the unit is in stand-by mode, it avoids the translation of the liquid freon toward the compressor.
Electronic expansion valve (VTEE)
The electronic expansion valve enables the maximum possible efficiency to be achieved by maximising the evaporator heat
exchange, minimising the reaction time to load variations and optimising the superheat. It is strongly recommended for use in
systems that will experience large load variations.
