15 Water system piping (Only 300D(S) ) In case of installing the unit at a place where outside temperature below freezing point, insulation must be provided for all hydraulic components. Water inlet or outlet pipes: The specification of the water inlet or outlet thread is RC3/4", which is external thread. Pipes should be heat-insulated well. Installation of the pipe for PT valve: The specification of the valve connecting thread is RC3/4", which is external thread. After installation, it must be confirmed that the drainpipe outlet is exposed in the air. Installation of the one way valve: The specification of the valve thread in accessories is RC3/4". It is used to prevent water from flowing backwards. The drainage pipe should be insulated to prevent water inside pipe from freezing in cold weather. After water system piping connection, turn on the inlet and outlet valve to effuse the tank. When water flow smoothly out from outlet pipe, the tank is full, turn off all valves to check the pipeline leakage. If the inlet water pressure is less than 0.15MPa (1,5atm), a pump should be installed at the water inlet. If the water supply hydraulic is higher than 0.65MPa (6,5atm), a reducing valve should be installed at the water inlet pipe. Condensate may be leaked from unit if drainage pipe is blocked, so a drainage pan should be installed as instruction below. 15

16 ATTENTION! Do not dismantle the PT Valve or block off the Drainage pipe, It will cause explosion and injury. To smoothly drain condensate, the unit should be installed at a horizontal floor. Otherwise, the drain vent is ensured at the lowest place, and recommending the inclination angle of unit to the ground should be no more than 2.

20 Solar energy coil electrical control instruction - CN26 is the terminal for solar input signal This terminal is used for receiving 230V feedback signal. If CN26 gets 230V feedback signal, CN2 will output control signal, to control solar pump; if CN26 have not gotten feedback signal, the solar pump will never turn on. And CN26 is connecting with VH-3 terminal. CN2 is the terminal for solar pump control This terminal utilizes the 230V control signal, to control solar pump. And this terminal is connecting with VH-3 terminal. Note: solar pump must be controlled through AC contactor. The CN2 is not allowed to drive the pump directly. CN17 is the ON/OFF terminal This terminal is used to receiving ON/OFF signal. When the signal close, the heat pump will never turn on. When the signal open, the heat pump will run well. And CN17 is connecting with VH-2 terminal. Heat pump installation guide for solar pipe For Calor Top 300D(S) model there are two routine guides for solar pipe installation. But the relevant parts should be provided by users. Guide 1:. When the pump station check the solar water temperature is OK, it will output 230V signal, when the CN26 get this signal, the heat pump CN2 will output 230V signal to drive the solar pump. 20

21 . When the heat pump check the temperature on the water box T5U 65, no matter whether CN26 get the signal or not, CN2 will never output 230V signal, solar pump can t work. Until water temperature turn down to T5U 60, the CN2 will make the solar pump work. Note: Usando If we use guide 1, when the solar pump work, the heat pump can also operate normally. Guide 2:. When the pump station check the temperature is OK in solar pipe, it will output 230V signal, and the CN26 will get this signal, then the CN2 will output 230V signal to control the contactor, the contactor will close, the solar pump will turn on. And the CN11 will check the ON/OFF signal; the heat pump will stop operating.. When the pump station check the temperature is not OK, it will stop output 230V signal, CN2 will also stop output 230V signal, the contactor open, solar pump will turn off. And the CN11 check the ON/OFF signal, the heat pump will operate.. When the heat pump check the water temperature on the water box T5U 65, no matter whether CN26 get the signal or not, the CN2 will not output 230V signal, solar pump can t work. Until the water temperature on the water box T5U 60, the CN2 will make the solar pump work. Note: If we use guide 2, when the solar pump work, the heat pump cannot operate. 23

22 2.9 Water affusion and effusion Water affusion: If the unit is used for the first time or used again after emptying the tank, please make sure that the tank is full of water before turning on the power. Caution: The Ball valve at water inlet should be open when the unit is in operation. Operation without water in water tank may result in damage of auxiliary e-heater. Due to such damage, the supplier is not responsible for the quality issue. Water effusion: If the unit needs cleaning, moving etc., the tank should be emptied. Note: The outlet water temperature maybe very high when emptying, beware of your body for burns. 22

23 2.10 Trial run Checking list before trial- running: Correct installation of the system. Correct connection of water/air piping and wiring. Condensate draining smoothly well insulation work for all hydraulic part. No obstacle outside the air inlet and outlet. Correct power supply. No air in the water pipeline and all valves opened. Effective electric leakage protector installation. Sufficient inlet water pressure, between 0.15MPa and 0.65MPa (1,5 atm ~ 6,4 atm). Water temperature display The temperature shown of the display depends on the upper sensor. It is normal that the display temperature has reached to target temperature but compressor still running, because the lower water temperature does not get to target temperature. Heat source shift The default heating source is heat pump. If the ambient is range out of heat pump, heat pump will stop running, and the unit will shift automatically to activate E-heater and show the icon LA on the display, then if the ambient temperature goes into the running range of heat pump again, it will stop E-heater and shift automatically to heat pump again, and the icon LA will be extinguished If the target setting water temperature is higher than the maximum temperature (Heat pump), the unit will activate heat pump firstly to the maximum temperature, then stop heat pump, activate E-heater to continually heat water to the target temperature. If manually activate the E-heater running mode when heat pump running, E-heater and heat pump will work together until the water temperature gets to target temperature. So if want to heat quickly, E-heater should be activated manually. E-heater will be activated once for the current heating progress, if want to apply E-heater again, the button of E-HEATER should be pressed once. Note: In the E-heat mode, only half tank of water, i.e. 150L, could be heat every time. How is the unit running? If unit is OFF, press and the unit will be waken, then press to set target water temperature(38~60 ),press and the unit will automatically select mode and start to heat water to target temperature. Note: If system occurs some malfunctions, error code E7 and will be shown on the display, then heat pump will stop running and the unit will activate automatically E-heater as the backup heat source, but the code E7 and will be shown until power off. 23

30 2.14 Non-error tips Q: Why compressor can t start immediately after setting? A: Until will wait for 3 min. to balance the pressure of system before start compressor again; it s a self protection on unit. D: Why sometimes the temperature shown on the display panel decrease while unit is running? R: When the upper tank temperature is much higher than the bottom part, upper part of hot water will be mixed by the bottom cold water wich is continually flow from inlet tap water so that will decrease the upper part temperature. D: Why sometimes the temperature shown the display panel decrease but unit still keep closed? R: To avoid unit ON/OFF frequently, unit will activate heate source only when bottom tank temperature is lower than setting temperature for at least 5 C. D: Why sometimes the temperature shown the display panel decrease dramatically? R: Because tank is pressure-bearable type, if there is massive hot demand, hot water will quikly tapped out from upper part of tank as well as cold water will quikly tapped into bottom part of tank. If the cold water surface emerge the upper temperature sensor, temperature shown on the display will decreased dramatically. D: Why sometimes the temperature shown the display panel decrease a lot but there is still a mount of hot water that can be tapped? R: Because the upper water sensor is located on the upper ¼ of tank; when tapping hot water out, it means there is at least ¼ tank of hot water available. D: Why sometimes unit shows LA on display? R: The heat pump available running ambient range is -7 C ~ 43 C; if ambient temperature is out of range, system will show above mentioned signal to let user notice it. D: Why sometimes there is nothing shown on the display? R: To mantain display screen lifespan within along term, when there is no button operation for 30 sec. it will extinguish the display except LED indicator. D: Why sometimes the buttons are unavailable? R: If there is no operation on panel for 1 min. unit will lock the panel and shows ; to unlock the panel, please press ENTER button for 3 sec. D: Why sometimes there is some water flowed from drainage pipe of PT valve? R: Because the tank is pressure-bearable one; when water is heated inside the tank, water will expand, so the pressure inside of tank will increase. If pressure goes up more than 1 MPa, PT valve will activate to relief the pressure and hot water drop will be discharged correspondingly. If water drop is continually discharged from PT valve drainage pipe, it is abnormal; please contact qualified stuff to repair. Something about self-protection of unit When the self protection happens, the system will be stopped and start self-check and restart when the protection is resolved When the self protection happens, the buzzer will buzz in every other minute, the icon will flash and error code will be shown at water temperature indicator. Press CANCEL button for 1 sec. to stop buzz, but the icon and error code does not disappear until protection resolved. In the following circumstance, self-protection may happen: Air inlet or outlet is blocked, Evaporator is covered with too much dust or Incorret power supply (exceeding the range of V). 30

31 Defrosting function In the Economy Mode, if the evaporation frosts in a cold circumstance, the system will defrost automatically to keep effective performance (3~10 min). During defrosting, fan stops working, four-way valve reverses the flow direction, and compressor keeps working. _ Conditions to activate defrosting cycle: When T3 0, Compressor is continually running for 40 minutes. (If compressor restarts frequently, which can only run within 10 minutes. For each start cycle, system will count accumulated running time, when accumulated running time reaches 40 minutes defrosting cycle will activate 2 minutes after compressor s next start). _ Conditions to inactivate defrosting cycle: 1. Defrosting time reaches 10 minutes 2. T3 15 C _ Main components movement when defrosting Self-protection detection When the self-protection happens, the system will be stopped and start self-check, and restarts when the protection resolved; When the self-protection happens, the buzzer will buzz in every other minute, the Warning indicator glitter and the display indicate the error code and water temperature alternatively.

41 2.18 Typical applications in cooling and purification of air With duct connection or without it Without duct connection In case of a closed room with internal heat sources, the unit can work optimally without the need to ducting, sucking hot air and putting cooled and dehumidified air in the room. Suitable premises for installation without ducting: - laundry / drying room; - unheated rooms; - unheated rooms; - technical rooms; - rooms without internal loads but with openings for air circulation; With internal heat sources Cold air outlet Hot air inlet Without internal heat sources Cold air outlet Hot air inlet 41

42 In a room without internal heat sources, for a correct operation of the machine is necessary to ensure some ventilation to prevent the excessive decreases of internal temperature. With duct connection In case of a closed room, without air exchange and without internal heat loads, use of ducts is necessary to avoid excessive cooling of the room, and then a malfunction of the unit. - Hot air extraction With air duct is possible to extract hot air from a room with thermal loads and put it externally. In this way the unit works with high performance and extracts heat from a with thermal loads. - Dehumidification and air exchange With air ducts the unit can suck hot air from the outside and carry it cooled and dehumidified in a certain room, ensuring the exchange of air. 42

43 - Dehumidification and cooling With air ducts it is possible to suck hot air from a room with thermal loads and re-insert it cooled and dehumidified. - Without any environmental impact With air ducts it is possible to install the unit inside a closed room without alterate the internal temperature, sucking air from outward and carry it out. 43

44 2.19 Running Logic Parameters: T4 ambient temperature Tstop Max. water temperature which heat pump can reach in accordingly T4 Ts setting (desired) water temperature T5U UP water tank temp T5L LOW water tank temp HEAT PUMP 1) When in below conditions, the heat pump start (only compressor): a) T5L < min(ts-10 C ; Tstop-10 C) or b) T5L < 35 C or c) T5U < min(ts-5 C ; Tstop-5 C) Example : case a i) Ts = 50 C and T4 = 3 C then Tstop = 55 C T5L < min (40 ; 45) T5L < 40 C Water is heated only by Heat Pump, until T5L reaches the desired temperature (50 C) ii) Ts = 50 C and T4 = - 3 C then Tstop = 42 C T5L < min (40 ; 32) T5L < 32 C 44 N.B. Heat pump start at 35 C however (case b). Water is heated only by Heat Pump, until T5L reaches the stop- temperature (42 C). Now heat pump stops and the unit automatically activates the resistance E-heater to reach the desired temperature (50 C)

45 case c i) Ts = 50 C and T4 = 3 C than Tstop = 55 C T5U < min (45 ; 50) T5U < 45 C Water is heated only by Heat Pump, until T5L reaches the desired temperature (50 C) ii) : Ts = 50 C and T4 = -3 C than Tstop = 42 C T5U < min (45 ; 37) T5U < 37 C Water is heated only by Heat Pump, until T5L reaches the stop-temperature (42 C). Now heat pump stops and the unit automatically activates the resistance E-heater to reach the desired temperature (50 C). 2) When in below condition, the the heat pump stop: Example : T5L min (Ts ; Tstop) i) : Ts = 50 C and T4 = 3 C then Tstop = 55 C T5L min (50 ; 55) T5L 50 C 45

46 RESISTANCE E-HEATER 3) E-heater mode (only electrical resistance) is automatically activated in following conditions: a) When -7 C < T4 < 45 C: If Ts > Tstop (when T5L=Tstop, heat pump stops, and if T5U < (Ts-1 C), heat pump turn into E-heater mode) Example: i) Ts = 50 C and T4 = 3 C then Tstop = 55 C Ts > Tstop? NO Water is heated only by Heat Pump, until T5L reaches the desired temperature (50 C). Electrical resistance is not necessary! ii) Ts = 50 C e T4 = -3 C quindi Tstop = 42 C Ts > Tstop? YES When T5L = 42 C Heat Pump stop running, and if T5U < 49 C resistance automatically start, until T5L reaches the desired temperature (50 C) If T4 < 5 C (After Heat Pump has worked for 6 hours, and T5U < 35 C, then the unit switch on E-heater mode (working together with Heat Pump) b) When T4 > 45 C or T4 < -7 C When the water temperature sensor T5U < Max (Ts-10 C ; 35 C) E-heater mode start working. Example: Ts = 50 C T5U < Max (40 ; 35) T5U < 40 C 4) E-heater mode automatically stop working in following condition: When T5U Ts-1 C Example: Ts = 50 C T5U 49 C 46
