- Set the speed on the heating medium pump 2 gp6 using the switch gp6 sf4 on the pump select speed i ii or iii you see the speed selected on the left above the switch the display to the right above the switch must not be illuminated at all 34
- Setting the pump speed 34
- Setting the ventilation 34
- The factory setting for ventilation on the heat pump is high 75 ventilation must be set according to applic able norms the setting is made in menu 5 34
- The heat pump can be run without recovery as only an electric boiler to produce heat and hot water for ex ample before the ventilation installation is complete 34
- Then enter menu 5 fan sp exhaust air and reduce the fan speed to 0 34
- To set the correct flow in the climate system the correct speed must be set for the heating medium pump in the different operating conditions 34
- Air is initially released from the hot water and venting may be necessary if gurgling sounds can be heard from the heat pump or climate system the entire system will require additional venting vent the heat pump through venting valve qm20 qm22 qm23 qm24 when venting f750 must be off 35
