1.3 Product Features
1.3.1 General
It’s a kind of integrated DC inverter unit that comprises cooling, heating and water heating functions, and up to 5.0
energy e󰀩ciency. It adopts R32 refrigerant and two-stage compressor. For heating, ambient temperature range is
-25~35°C while the leaving water temperature range is 20~60°C.
The S therm unit is designed specially for the European market where there is a demand for high-temperature
water. Thanks to the dual-stage compression and enthalpy gain through gas injection, the heating energy
e󰀩ciency at low temperature will rise up greatly with the leaving water temperature up to 60°C. The whole series
of products strictly comply with EN14511,EUROVENT energy efficiency Class A and SCOP class A+++(35°C),
SCOP class A++(55°C) with EN14825. Their COP can reach up to 5.0. This unit can realize space heating and
sanitary hot water supply through terminal units, like the fan coil unit, oor coil and radiator. Environment-friendly
refrigerant R32 is adopted for the unit, with ODP of 0 and quite low GWP (=675). Besides, the adopted heat pump
technologies will reduce consumption of coal and other energy source and lower greatly CO2emission. Ranged
from 4.0kW~9.5kW, it is widely applicable to small and medium-sized apartment, large-sized villa etc.
1.3.2 Features
◆Wide Operation Range
Heating: -25~35°C; Cooling: 10~48°C; Water Heating: -25~45°C
◆Unique Low-Temp Hi-heat Dual-stage Compressor
(1) Under low-temperature conditions, compared with the conventional compressor, the dual-stage low-temp
hi-heat compressor will generate less loss of heat capacity and get higher energy e󰀩ciency.
(2) Floodback, high discharge temperature and other problems can be completely avoided under low-temp
conditions and the compressor’s reliability will be enhanced greatly.
(3) Dual-stage compression, dual-stage throttling and intermediate enthalpy adding through gas injection will
raise the leaving water temperature and improve the control accuracy.
(4) Values of resistance to compressor status:
4/6kW——UV/VW/UW:1.67±7%Ω
8/10kW——UV/VW/UW:0.99±7%Ω
◆High-e󰀩ciency Component(Inverter pump, Inverter fan, Plate heat exchanger)
(1) The A-class high-efficiency inverter water pump which complies with the European ErP directive, can
control the running frequency based on the actual load. Therefore, it can enhance the operation e󰀩ciency
and control the water temperature more accurately.
(2) The DC inverter fan can control the air volume accuratately and make the system run more stably and save
more energy.
(3) The high-e󰀩ciency plate heat exchaner will improve the unit’s performance largely.

3
(4) The high-e󰀩ciency water pump will also improve the unit’s performance largely.
◆All-in-one Design
(1) The unit can integrate with terminal units, like the radiator, oor heating device, FCU, water heating device,
solar kit, gas furnace etc. Versatile functions can meet various kinds of demands from di󰀨erent users and
enhance applicability of this product.
(2) The all-in-one structure design can save more installation cost, reduce risks of refrigerant leak, and improve
safety and reliability of the system.
◆Brand-new Controller
(1) White appearance, exquisite design, and the wall-mounted design that facilitates installation.
(2) Liquid crystal display and touch-screen operation.
(3) The 12V JACK interface can supply power to the control separately and lengthen the communication
distance.
(4) The remote monitoring interface can monitor the unit through the Mobus interface and be integrated into the
BMS system.

◆Smart Control, Powerful Function
(1) The operating mode can be switched freely. Furthermore, based on di󰀨erent demands, the holiday mode,
weather-dependent mode, quite timer, temperature timer and oor commissioning can activated.
(2) Multiple protections can make this product much safer. The added electric heater will prevent the plate heat
exchanger from being frosted owing to too low water temperature and resultantly extend the service life of
the product and enhance its safety and reliability.
(3) The newly developed smart defrosting control program, “do defrost when necessary; do not defrost when
unnecessary; defrost more when it frosts heavily; defrost less when it frosts lightly”, can bring more
comfortability, avoid inadequacy of heat supply and ensure sustainable heat supply for the users.

Notes
(a) Leakage Switch is necessary for additional installation. If circuit breakers with leakage protection are in use,
action response time must be less than 0.1 second, leakage circuit must be 30mA.
(b) The above selected power cable diameters are determined based on assumption of distance from the
distribution cabinet to the unit less than 75m. If cables are laid out in a distance of 75m to 150m, diameter of
power cable must be increased to a further grade.
(c) The power supply must be of rated voltage of the unit and special electrical line for air-conditioning.
(d) All electrical installation shall be carried out by professional technicians in accordance with the local laws
and regulations.
(e) Ensure safe grounding and the grounding wire shall be connected with the special grounding equipment of
the building and must be installed by professional technicians.
(f) The specications of the breaker and power cable listed in the table above are determined based on the
maximum power (maximum amps) of the unit.
(g) The specications of the power cable listed in the table above are applied to the conduit-guarded multi-wire
copper cable (like, YJV XLPE insulated power cable) used at 40°C and resistible to 90°C (see IEC 60364-5-
52). If the working condition changes, they should be modied according to the related national standard.
(h) The specifications of the breaker listed in the table above are applied to the breaker with the working
temperature at 40°C. If the working condition changes, they should be modified according to the related
national standard.
(i) A circuit breaker must be added to the fixed line. The circuit breaker is all-pole disconnected and the
breaking distance of the contact is at least 3mm.
