The mode for setting the internal temperature is reached when we are in the initial mode in the main menu by pressing the OK button twice. This device is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the device by a person responsible for their safety. You can find the serial number in the lower right corner of the front cover and in the information menu (menu 3.1).
The heat pump can be connected to an optional low temperature heat distribution system. Clear information about the status, operating time and all temperatures in the heat pump is shown on the large and easy-to-read display. ႑ Scheduling indoor comfort and hot water (accessory) Heating and hot water, as well as cooling and ventilation can be scheduled for every day of the week or for longer periods (holidays) in some cases.
The heat pump has a large display with easy-to-understand menus that make it easier to set a comfortable climate. In the event of an error, the heat pump's display shows what has happened and what needs to be done.

Menu system
This symbol appears next to the information sign if there is information in menu 3.1 that you should be aware of. This symbol indicates the actual speed of the fan if the speed has been changed from the normal setting. To advance in the menu system, select a main menu by highlighting it and then pressing the OK button.
Select one of the submenus by highlighting it and then pressing the OK button. The background of the value turns green, indicating that you have entered setup mode. Turn the control knob to the right to increase the value and to the left to decrease the value.
Turn the control knob until one of the arrows in the upper left corner (by the page number) is highlighted. The help text often consists of several windows that you can move between with the control button.

You can find the safety valve on the incoming pipe (cold water) to the water heater.
Saving tips
Example: A family with 2 children lives in a house with 1 flat screen TV, 1 digital box, 1 DVD player, 1 TV game console, 2 computers, 3 stereos, 2 light bulbs in the toilet, 2 light bulbs in the bathroom, 4 lamps in the kitchen, 3 lamps outside, a washing machine, tumble dryer, refrigerator, freezer, oven, vacuum cleaner, engine block heater = 6240 kWh household electricity/year. Newly built houses usually have double energy meters, use the difference to calculate your electricity consumption at home.
Set the indoor climate
Overview
The number of steps in which the value must be changed to achieve a one degree change in internal temperature depends on the heating unit. The new value is shown to the right of the symbol on the screen. The rise in room temperature can be slowed down with thermostats for radiators or underfloor heating.
Therefore, open the thermostatic valves all the way, except in those rooms where a lower temperature is required, e.g. If it is cold outside and the room temperature is too low, increase the slope of the curve in menu 1.9.1 by one step. If it is cold outside and the room temperature is too high, lower the curve slope menu 1.9.1 by one step.
If it is warm outside and the room temperature is too low, increase the value in menu 1.1 by one increment. If it is warm outside and the room temperature is too high, reduce the value in menu 1.1 by one increment.
Day: Select which day or days of the week the schedule applies to. To remove the schedule for a particular day, the time for that day must be reset by setting the start time equal to the stop time. Time period: Here the start and stop time for the selected day are selected for planning.
Adjustment: Here you set how much the heating curve must be shifted in relation to menu 1.1 during scheduling. If you want to set similar schedules for each day of the week, start by filling in "all" and then change the desired days. If the stop time is before the start time, this means that the period extends past midnight.
Short periods in combination with underfloor heating, for example, will not give a noticeable difference in room temperature.
Here, increases or decreases in the ventilation of the accommodation can be planned for up to two periods per day. If two settings conflict, a red exclamation mark appears at the end of the line.
The slope of the heating curve indicates by how many degrees the supply temperature must increase/decrease when the outside temperature drops/increases. The heating curve is set when the heating installation is installed, but may need to be adjusted later. In case fine adjustments are made to the internal temperature, the heat curve should instead be moved up or down, this is done in the temperature menu 1.1.
A displacement of the heating curve means that the supply temperature changes equally for all the outside temperatures, e.g. Supply temperature - maximum and minimum values Because the supply temperature cannot be calculated higher than the set maximum value or lower than the set minimum value, the heating curve flattens out at these temperatures. If you only have one heating system, the basket number is already marked when the menu window is opened.
Select the system (if more than one) for which the heat curve should be changed. The heat curves are numbered from 0 to 15, the higher the number, the steeper the slope and the higher the supply temperature. Turn the control knob so that the ring on the shaft is marked with the outside temperature.
Follow the gray line up to the heating curve and outwards to the left to read the supply temperature value at the selected outdoor temperature. You can now select a reading for different outside temperatures by turning the control knob to the right or left to read the corresponding supply temperature. If it is cold outside and the room temperature is too low, increase the slope of the curve by one step.
If it is cold outside and the room temperature is too high, decrease the slope of the curve by one increment. If it is warm outside and the room temperature is too low, increase the offset curve by one increment. If it is warm outside and the room temperature is too high, lower the offset curve by one increment.
Set the minimum temperature to the supply temperature of the climate system during cooling operation. Set the desired temperature to the flow temperature in the climate system during cooling operation when the outside temperature is +20 °C. Set the desired temperature to the flow temperature in the climate system during cooling operation when the outside temperature is +40 °C.
Here you can set how long the F1145 must wait before returning to heating mode when the cooling demand has ended or vice versa. This setting option only appears if a room temperature sensor is connected to F1145 and has been activated. Here you can set how far the room temperature must fall below the desired temperature before F1145 switches to heating mode.
Here you can set how high the room temperature can rise above the desired temperature before the F1145 switches to cooling.

Adjust the heat pump
When the pool temperature falls below the set start temperature and there is no hot water or heating requirement, F1145 starts the pool heating. The start temperature cannot be set to a value higher than the stop temperature.
In this operating mode, you cannot choose which functions should be allowed because they are automatically managed by the heat pump. In this operating mode, the compressor is not active and only additional heating is used. If "compressor" is cancelled, the symbol appears on the heat pump symbol in the main menu.
34;addition" is what helps the compressor to heat the accommodation and/or the hot water when it cannot handle the entire need on its own. You can deselect the function when you do not want the cooling to run. This alternative requires an accessory for cooling or if the heat pump has a built-in function for cooling.
If you deselect "addition", this may mean that adequate heating in the accommodation is not achieved.
Holiday scheduling starts at 00:00 on the start date and stops at 23:59 on the stop date. Complete vacation setting about a day before your return so that room temperature and hot water have time to regain normal levels. Preset the vacation setting and activate just before departure to maintain the comfort.
If you choose to turn off hot water production during the holidays, "period surges" (prevention of bacterial growth) are blocked during this time.
Degree minutes are a measure of the actual heating demand in the home and determine when the compressor or additional heat will start/stop. A higher value in "compressor start" gives more compressor starts, which increases wear on the compressor.
