Customer benefits
Designed for light commercial applications.
Being extremely versatile, they can provide hot water for winter heating, sanitary hot water and chilled water for summer cooling.
The system works seamlessly with radiant and fan coil systems using network or renewable sourced power supply
Can provide hot water for winter heating, sanitary hot water at 58°C (up to 65°C with auxiliary electric heater) and chilled water for summer cooling.
The DC inverter compressors allow saving up to 25% in power consumption. The inverter compressors optimized for heat pump operation under heavy conditions with a steam injection system to provide a high level of comfort with low energy consumption even in the winter season (down to -25°C ambient air temperature).
Options
Models 6 to 16 kW
3D Reversible heat pump with integrated defrosting kit
All units can work in three mode: heating, cooling and energy recovery mode
Control handles mixing valves, diverter and circulatory secondary system
Control can also manage external solar and thermal systems
Remote control also available as an option
Controller manages also the following functions: regulation of the water temperature, antifreeze protection, time setting and compressors startup sequence, reset and management of alarms, fans modulation and pump modulation.
Upon request, it is possible to connect the microprocessor to a BMS remote control system by mean of Modbus protocol.
The control system together with the INVERTER technology and the on board sensors continuously monitors and adapts the performance of the inverter compressor, circulating pump and of the fan.
Hi-T option
The Hi-T is a touch screen remote control for centralized management of a network of chiller/heat pump system.
It manages also partial functions (i.e. as a remote control panel of a single chiller/heat pump or thermostat of the zones management).
It integrates humidity and temperature sensors for the thermo hygrometric analysis of the environment and for the management of the double set point for radiant floor heating systems that use a dehumidification system.
The intuitive interface simplifiers the use of the control
The remote control supervises periodically the network, there is a cycle time that elapses between the signaling or command request and the activation of the function, the cycle time depends on the largeness of the fan coil units and-or heat pumps network.
