Engineering Data
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
effcieicy 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-
efficiency plate heat exchaner will improve the unit‘s performance largely.

All-in-one Design
1. The unit can integrate with terminal units, like the radiator, floor heating device, FCU, water heating
device, solar kit, gas furnace etc. Versatile functions can meet various kinds of demands from different 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 will facilitate 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 running mode can be switched freely. Furthermore, based on different demands, the holiday
mode, weather-dependent mode, quite timer, temperature timer and floor commissioning can activated.
2. Multiple protections can make this product much safer. The added electric heater will prevent the
plate heat exchanger from being frostbitten 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 wh
en it frosts lightly‖, can
bring more comfortability, avoid inadequacy of heat supply and ensure sustainable heat supply for the
users.
