F1245 is connected to the brine and heating medium circuits. In the heat pump evaporator, the brine (water mixed with anti-freeze, glycol or ethanol) releases its energy to the refrigerant, which is vaporised in order to be compressed in the compressor. The refrigerant, of which the temperature has now been raised, is passed to the condenser where it gives off its energy to the heating medium circuit and, if necessary, to the water heater. If there is a greater need for heating/hot water than the compressor can provide there is an integrated immersion heater. ;/ Tundish ;/ ;/ ;/ ;/ ;/ Temperature sensor Level vessel Expansion vessel P Pressure gauge Circulation pump Particle filter Auxiliary relay Compressor Heat exchanger XL 1 XL 2 XL 3 XL 4 XL 6 XL 7 NIBE™ F1245 Connection, heating medium flow Connection, heating medium return Connection, cold water Connection, hot water Connection, brine in Connection, brine out Chapter 4 | Pipe connections 13 Brine side Collector Type Surface soil heat, recommended collector length (m) Rock heat, recommended active drilling depth (m) 10 kW 400-2x300 150-180 75 70 Dimensions and pipe connections 25-50 560 440 In those cases where it is necessary to have several collectors, these should be connected in parallel with the possibility for adjusting the flow of the relevant coil. 50 For surface soil heat, the hose should be buried at a depth determined by local conditions and the distance between the hoses should be at least 1 metre. 25 620 430 ;/ The length of the collector hose varies depending on the rock/soil conditions, climate zone and on the climate system (radiators or underfloor heating).

The slope of the heating curve indicates how many degrees the supply temperature is to be increased/reduced when the outdoor temperature drops/increases. A steeper slope means a higher supply temperature at a certain outdoor temperature. The optimum slope depends on the climate conditions in your location, if the house has radiators or under floor heating and how well insulated the house is. The heating curve is set when the heating installation is installed, but may need adjusting later. Thereafter the heating curve should not need further adjustment. Caution In the event of making fine adjustments for the indoor temperature, the heat curve must be offset up or down instead, this is done in menu 1.1 temperature . RXWGRRU WHPS r& heating curve Setting range: 0 - 15 Default value: 9 In the menu heating curve the so-called heating curve for your house can be viewed. The task of the heating curve is to give an even indoor temperature, regardless of the outdoor temperature, and thereby energy efficient operation. It is from this heating curve that the heat pump’s control computer determines the temperature of the water to the heating system, flow line temperature, and therefore the indoor temperature. You can select heating curve and read off how the flow line temperature changes at different outdoor temperatures here.

If it is cold outdoors and the room temperature is too high, lower the curve slope by one increment. If it is warm outdoors and the room temperature is too low, increase the curve offset by one increment. If it is warm outdoors and the room temperature is too high, lower the curve offset by one increment. Basic values for the automatic heating control The values stated on the map apply for the "heating curve“ in menu 1.9.1. ႑ The first value applies for low temperature* radiator systems. "temperature" (heating curve offset) in menu 1.1 must be set to -2. ႑ The value in brackets refers to under floor heating systems** installed in concrete floor structures. ႑ When the system is installed in a timber floor structure you can use the number before the brackets, but this value must be reduced by two units. "temperature" (heating curve offset) in menu 1.1, set in these cases to -1. Caution The map values are usually a good starting point and concern an approximate room temperature of 20 °C.

NIBE™ F1245 Chapter 9 | Service 63 10 Disturbances in comfort In most cases, the heat pump notes operational interference (operational interference can lead to disturbance in comfort) and indicates this with alarms and shows action instructions in the display. Troubleshooting Info-menu Basic actions All the heat pump measurement values are gathered under menu 3.1 in the heat pump menu system. Looking through the values in this menu can often simplify finding the fault source. See page 44 for more information about menu 3.1. Start by checking the following possible fault sources: ႑ The switch's (SF1) position. ႑ Group and main fuses of the accommodation. ႑ The property's earth circuit breaker. ႑ The heat pump's miniature circuit breaker (FA1). ႑ The heat pump's temperature limiter (FD1). Manage alarm /RZ SUHVVXUH DODUP DODUP LQIR DFWLRQ If the operational interference is not shown in the display the following tips can be used: Low hot water temperature or a lack of hot water ႑ Closed or choked filling valve for the hot water ႑ UHVHW DODUP DLG PRGH In the event of an alarm, some kind of malfunction has occurred, which is indicated by the status lamp changing from green continuously to red continuously. In addition, an alarm bell appears in the information window. ႑ ႑ ႑ Alarm In the event of an alarm with a red status lamp a malfunction has occurred that the heat pump cannot remedy itself. In the display, by turning the control knob and pressing the OK button, you can see the type of alarm it is and reset it. You can also choose to set the heat pump to aid mode. info / action Here you can read what the alarm means and receive tips on what you can do to correct the problem that caused the alarm. reset alarm In most cases it is enough to select "reset alarm" to correct the problem that caused the alarm. If a green light illuminates after selecting "reset alarm" the alarm has been remedied. If a red light is still visible and a menu called ”alarm” is visible in the display, the problem that caused the alarm remains. If the alarm disappears and then returns, see the troubleshooting section (page 64). aid mode ”aid mode” is a type of emergency mode. This means that the heat pump produces heat and/or hot water despite there being some kind of problem. This can mean that the heat pump's compressor is not running. In this case the immersion heater produces heat and/or hot water. Caution Selecting "aid mode” is not the same as correcting the problem that caused the alarm. The status lamp will therefore continue to be red. Low room temperature ႑ Closed thermostats in several rooms. ႑ ႑ ႑ ႑ ႑ ႑ ႑ 64 Chapter 10 | Disturbances in comfort heater. ႑ Open the valve.
