Page 7 1.3.2 Features Wide Operation Range ◆ Heating: -25~35°C; Cooling: -15~48°C; Water Heating: -25~45°C Unique Low Ambient Dual-stage Compressor ◆ (1) Under low-temperature conditions, compared with the conventional compressor, the dual-stage low ambient dual-stage compressor will generate less loss of heat capacity and get higher energy efficiency. (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.
Page 8 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.

Page 43: Quantity And Location Of The Water Manifolds
Square-shaped Coil (Recommended) U-shaped Coil Length of coils is calculated as below: Square-shaped coil: =L*W/tube spacing=area/tube spacing U-shaped coil: =L-1+L*W/tube spacing=L-1+area/tube spacing The reason why the square-shaped coils are recommended is because they can keep even temperature distribution. Special demand can be met by adjusting the tube spacing. Distance from the room to the water manifold should be estimated according to the actual conditions of the project and generally should not exceed 30m.
Page 44: Requirements On Installation Of The Water Manifold
Example for how to calculate the floor heating area per single loop: when the tube length is 120m, and tube spacing is 200mm, then the floor heating area per single loop is 120×0.2=24m (4) One trap (collector) cannot be used for different floors, or it would cause uneven water distribution. (5) Distance between the unit and the water manifold should be within 15m.
Page 45: Section Of Fcu
(3) The water supply valve should be installed upstream of the water manifold and the return valve should be installed downstream of the water manifold. (4) A filter is required upstream of the water manifold. 4 Section of FCU 4.1 FCU Type Selection The air-water fan coil unit is optional for Vezuri units.

Page 51 (11) The tempeaure sensor for the vapor line is used to detect the temperature of the vapor refrigerant line. Under the Cooling mode, it and that for the liquid line together are used to control the opening of the electronic expansion valve 1.

2.1.2 Freeze Protection When it is detected that the leaving water temperature of the plate heat exchanger is lower than the freeze protection temperature, the compressor will drop its operating frequency until it reaches the minimum operating frequency. Then if it is still detected that the leaving water temperature is lower than the freeze protection temperature, the main unit will stop as per the shutdown frequency but the water pump keeps normal operation.
Page 54: Shutdown
(4) Over-temperature Protection for Water Heating When the compressor is running, if it is detected that the leaving water temperature of the auxiliary electric heater of the main unit is higher than the over-temperature protection temperature, the compressor will lower its operating frequency until it reaches the minimal operating frequency.
Page 55: Control To The Water Pump
2.8 Control to the Water Pump The water pump firstly will run at the initialized speed and then adjust the speed according to the entering/ leaving water temperature difference. When the temperature difference is large, the fan runs at the high speed. When the temperature difference is small, the fan runs at the low speed.
