Page 9: Principle Of Operation Of The Heat Pump
RINCIPLE OF OPERATION OF THE HEAT PUMP THE BASIC PRINCIPLE OF OPERATION OF A HEAT PUMP A heat pump operates similarly as a refrigerator. In a refrigerator, liquids evaporate due to received thermal energy from the surrounding air and this energy is emitted at a desired spot during condensation (Carnot’s cycle). -
Page 10: In Time Of Absence
2.3.4 In time of absence Complete shutdown of a heat pump can lead to higher heating costs. We recommend using the vacation mode, which lowers the temperature of heating and domestic water during your absence, but does not allow the system to get completely cold, which would cause higher heating costs upon system restart. - Page 11 – Incorrect ventilation of premises (when ventilating rooms, make sure the radiators are closed); – The charged quantity of used heat for central heating of premises depends mainly on the average outside temperature, so the consumption increases in the start of the heating season, usually achieves the highest value in January, and decreases at the end of the heating season;...

Page 12: Emergency Operation
4 EMERGENCY OPERATION Emergency operation is the operation of a heat pump with auxiliary heating sources such as electric heaters, gas furnace, oil furnace or other heating source controlled by the heat pump. Emergency operation is divided into Automatic and Manual operation. Automatic Emergency Mode: If the control detects that it cannot run the heat pumps as sources of heating due to possible errors, additional heating sources for heating system and heating sanitary water will be... - Page 13 Emergancy switch in OFF position – Heat pump works according to teh settings on the main controller (tuch-screen controll panel) Emergancy switch in ON position – Setting of teh main controller (tuch-screen controll panel) will be disabled. All Circulating pumps (P0, P1, P2 an P3) start to work (always ON). Temperature controll is only with Digital thermostat (controlling the set temperature of electrical heaters).

6 RISING / LOWERING THE ROOM TEMPERATURE There are two posibilitis, to contrll the room temperature: Exclusively accordint to Ambient temperature (Outdoor temperature) 2. Combination of Ambient temperature and Room temperature XCLUSIVELY ACCORDING TO AMBIENT TEPPERATURE By pressing in the middle of the house an additional window appears. First window is for setting the Paralel move of the Heating curve for the First Heating Circuit. -
Page 21: Quick Settings
7 QUICK SETTINGS What is a parallel move of the heating curve? At start-up, the heating curve is adjusted according to the heating system (Floor heating system, Radiators, Fan coils) and desired room temperature. The setting can be changed from the Main screen, but only the complete move of the heating curve and not each reference point separately. -

By pressing on the room temperature display, an additional window appears. System 1 Heating Curve Parallel Move 2: 0°C Cancel First the window for parallel move of the first heating circuit appears. -
Page 23: Setting The Fixed Temperature Of Heating Circuit
In a heat pump system, a larger quantity of hot water is mixed with cold water, as the volume is larger and the temperature is lower (contributing to lower costs) than in the traditional system, where the water volume is 2-3 times smaller. SETTING THE FIXED TEMPERATURE OF HEATING CIRCUIT This quick setting is available only when one or both heating circuits are used without heating curves. -

Page 26: Heating/Cooling Stops Based On Water ∆T
9.1.1 Heating/Cooling Stops Based on Water ∆T Temperature setting that allows overheating of the heating system for the set value. The recommended setting is 2 °C! This enables efficient operation of the Inverter technology and brings the highest savings. Please note, that we allow the Heat Pump to overheat the system, to maintain a low working speed and to avoid a frequent stopping and starting of the compressor. -

9.1.6 Room temp. effect on Heating Curve When the temperature sensor ˝TR˝ is mounted in the living area, this function can make small corrections of the heating curve, depending on the set “Ideal Room Temp. in Heating”. Note: This feature does not mean temperature control by room temperature, but only a correction of the heating curve! If this feature is on and the temperature in the room (where the TR room temperature sensor is located) still exceeds the set ideal value, the heating curve settings should be reset! -

Page 30: Heating Curve
9.2.5 Heating Curve The heating curve mode is based on the condition that the lower the ambient temperature is, the higher the water temperature for the heating of facility is. This heating curve mode can help the heat pump to achieve a higher COP (efficiency rate) and increase the feeling of comfort in the house. -

9.2.5.1 SETTING THE HEATING CURVE FOR THE SECOND HEATING CIRCUIT Heating curve is set on page 2 of the “Heating/Cooling Circuit 2” menu! EXAMPLE Example: The customer wants the room temperature to be 21 °C, but the heat pump heats the rooms to 22 °C. In this case the heating curve must be lowered. -

Example: Desired temperature of domestic water is 47 °C, and the domestic hot water restart ∆T setting is 5 °C. (47–5=42) This means that the heat pump will restart the heating of domestic water when the temperature drops below 42 °C! Recommended domestic hot water restart ∆T setting is 5 °C! -

found in pipelines with low flow rates or where water was stagnant in pipes for a longer period of time (inactive parts of buildings, basement etc.). Domestic hot water storage tanks with layered temperature distribution are also possible sources of contamination. Legionella can also be found in cool water, but its growth is hindered, which makes it almost non- existent or at least very rare in subterranean waters and cold potable waters. -

Note: First heating season, it is recommended to clean the Filter first time after 1 month working of the heat pump and until the end of the firs heating season every 2 months. If there is still much dirt collecting in the filter, repeat this procedure until the system is free of excessive dirt. -
Page 52: Water Pressure In The System
12 WATER PRESSURE IN THE SYSTEM Water pressure must always stay above 1 bar of pressure. If the pressure falls below 1 bar, the Heat Pump will go in to protection S02 or S10, which can stop the Unit from working. Recommended water pressure when the unit is working is 1,5 bar and when it stays still approx. - Page 53 │ hvac@gorenje.com www.gorenje.com Thank you for reading the Instruction manual for the Gorenje heat pump.
