1.3 Unit description
B
HYDRONIC UNIT B
it is a range of heat pumps for the pro-
duction of hot water for space heating, domestic hot water for do-
mestic use (in combination with suitable boilers or exchangers) and
cold water for cooling.
Designed to be placed outdoors, it is suitable for use in residential
and commercial applications.
The compressor, of the Rotary (HYDRONIC UNIT 5) or Twin-
Rotary (HYDRONIC UNIT 7-11-15) type, is regulated by the DC
Inverter control with continuous power modulation. The compres-
sor, working in combination with the electronic expansion valve, is
therefore able to guarantee maximum environmental comfort while
maintaining high energy standards.
The fans are driven by a permanent magnet synchronous motor
and are continuously modulated to obtain maximum performance
in all conditions of use, maximizing the silence of the installation.
The hydronic module is always present and is supplied with a vari-
able speed circulation pump, flow switch, safety valve and inlet and
outlet water temperature probes.
The unit can be set and controlled by the remote control REC10CH,
the interface WUI, the free potential contacts or, if available, by an
existing modbus BMS.
1.4 Safety and adjustment devices
The safety and regulation of the appliance are obtained:
•
on the cooling circuit with
— refrigerant temperature sensor on the compressor discharge
— refrigerant temperature sensor on the compressor suction
•
on the hydraulic circuit with
— water temperature sensors the detection of the water inlet
and outlet temperature
—
flow switch to ensure unit operation with correct water flow
— safety valve with intervention pressure 300 kPa
•
The installer must necessarily provide in the system:
— a suitably sized expansion vessel
— a suitably sized technical water storage tank
— a by-pass valve between the delivery and return of the ap-
pliance to allow the circulation of water in the unit even if the
same is isolated from the system. This serves to make the
antifreeze protection logics effective.
—
a water filter entering the unit
— air vent valves in the highest points of the system
