Accessories
Rubber vibration
dampers
Allow to reduce the transmission to the unit support plane of the mechanical vibrations generated by the compressor and
by the fans in their normal operating mode, the degree of isolation is about 85%
Spring vibration
dampers
Allow to reduce the transmission to the unit support plane of the mechanical vibrations generated by the compressor and
by the fans in their normal operating mode, the degree of isolation is about 90%
Water paddle flow
switch
Allows to detect the water flow lack through the plate heat exchanger and operates as an integration of the protecion
offered by the differential pressure switch (standard).
Tank antifreeze
electrical heater
Activated together with the antifreeze electrical heater of the plate heat exchanger, it has the task to keep the still water
in the buffer tank at a temperature high enough to avoid ice generation during winter.
Remote control
It is suitable for wall mounting and reports all the control and visualization functions available on the user interface
placed on the unit. It therefore allows the complete remote control of the unit.
Programmer clock
It allows the unit to be turned on and off according to a set program, through the digital input available on the unit wiring
board (remote stand by).
Modbus serial
interface
on RS485
It allows to communicate with the unit controller and to view the operating conditions of the unit through Modbus com-
munication protocol. The RS485 serial line ensures the signal quality up to distances of about 1200 meters (that can be
extended by means of proper repeaters).
Phase sequence and
voltage controller
It checks not only the presence and correct order of the power supply phases but also the voltage level on each phase
and avoid the unit to operate with voltage levels outside the permitted limits.
Supplied accessories
Victaulic connections
This accessory consists of steel pipes that allows the water inlet/outlet to be connected straight inside the unit.
Coil protection grilles
Protects the external surface of the finned coil.
High and low pressu-
re gauges
2 pressure gauges allow visualization of high and low refrigerant gas pressure.
Coil shut off valves
It consists of two ball valves installed before and after the coil that allow for the pump-down maintenance.
Outdoor air sensor
External air probe mounted near coil allows smart defrosting, climatic variation of setpoint and enables heat pump stop
reducing the external air temperature below a setpoint.
High temperature
thermostat
Two thermostats in series on compressors outlet pipes preserve operation not allowing temperature to rise up than a
specified non adjustable value.
Low temperature kit
(di serie per unità IP e BP, optional per unità IR e BR) sono costituite da resistenze carter di riscaldamento olio compressori.
Tank antifreeze
electrical heater
Activated together with the antifreeze electrical heater of the plate heat exchanger, it has the task to keep the still water
in the buffer tank at a temperature high enough to avoid ice generation during winter.
Modbus serial
interface
on RS485
It allows to communicate with the unit controller and to view the operating conditions of the unit through Modbus com-
munication protocol. The RS485 serial line ensures the signal quality up to distances of about 1200 meters (that can be
extended by means of proper repeaters).
Phase sequence and
voltage controller
It checks not only the presence and correct order of the power supply phases but also the voltage level on each phase
and avoid the unit to operate with voltage levels outside the permitted limits.
ATC Advanced
temperature control
It consists of a properly calibrated pressure switch that partializes the unit preventing the high pressure alarm.
Pressure transducer
It consists of a transducer, which allows operation of the control condensation, evaporation and defrost by reading the
pressure.
