Wide Operating Range
1. All main components are DC frequency conversion technologies, with electronic expansion valve for precise adjustment, can ensure the stable operation of - 25℃~35 ℃ ambient temperature heating, - 25 ℃~43 ℃ ambient temperature for hot water, - 5 ℃~52 ℃ ambient temperature operation for cooling
2. Only with compressor, the maximum outlet temperature of heating wate

Energy Efficiency
The energy efficiency grade for whole series of Low Average working conditions meets A+++, and the energy efficiency grade of Medium Average meets A++

Flexibility
According to the actual installation conditions and using habits, users can choose one of the four control methods: outlet temperature control, indoor temperature sensor control, indoor temperature controller control, and buffer tank control to make the room comfortable and meet the users requirements

Dual-temperature Control
Association control mixing pumps and three-way valves can be supported to ensure that high temperature water (for heating radiator) and medium and low temperature water (for underfloor heating) can be provided at the same time to meet user's requirement

ECO mode
The double temperature zone can control the inlet water temperature independently and automatically according to the change of ambient temperature
