Commissioning 7 Tuning the system 7.1 Tuning the heating system To obtain a heating system balance and obtain an even and comfortable indoor temperature, the heating system may need adjustment according to the example below. The indoor temperature is adjusted by changing the heat curve. The heat curve calculates the supply temperature depending on the outdoor temperature. The lower the outdoor temperature, the higher the supply temperature.

Commissioning 8 Installation protocol and customer info Fill in the Installation protocol in the User Guide. After installation and test operation, the customer must be informed about their new heat pump installation. In the User guide there is a checklist regarding the information that the installer must give the customer. ! 26 The serial number must always be given for warranty matters. The serial number is on the type plate, which is attached to the heat pump and control unit.
Commissioning 9 Important information/Safety regulation 9.1 General safety precautions Warning Risk of personal injury! Children are not permitted to play with the product. Warning As the water temperature in DHP-H Opti Pro and DHP-L Opti Pro becomes extremely hot, a mixer valve must be installed between the cold water and hot water pipes to ensure a lower domestic hot water temperature. Alternatively the maximum hot water temperature must be reduced in the Service menu.
Commissioning 9.1 Caution The hot water tank must be equipped with an approved safety valve. Caution Heating systems with closed expansion tanks must also be supplied with approved pressure gauges and safety valves. Caution Cold and hot water pipes and overflow pipes from safety valves must be made of heat resistant and corrosion-resistant material, for example copper. The safety valve overflow pipes must have an open connection to the drain and visibly flow into this in a frost-free environment.
Commissioning Warning 9.4 Risk of personal injury! Refrigerant exposed to a naked flame creates a poisonous irritating gas. This gas can be detected by its odour even at concentrations below its permitted levels. Evacuate the area until it has been sufficiently ventilated. Work on the refrigerant circuit Caution When repairing the refrigerant circuit, the refrigerant must not be released from the heat pump, it must treated in the appropriate way.
Commissioning 9.3 9.4 30 Water quality Caution A normal heating system always contains a certain amount of corrosion particulates (rust) and sludge products from calcium oxide. This comes from acid that is naturally occurring in the fresh water that the system is filled with. It is not good practice to have to fill the heating system regularly which is why any leakage in the heating system should be repaired immediately. Normal filling should occur only once or twice a year.
