ranties and guarantees.
DisposalWhen decommissioning the unit, always comply with applicable laws, directives and standards for the recovery, recycling and disposal of materials and components.
“Dismantling”.
Heat meteringIn addition to proof of the unit’s efficiency, the EEWaermeG also requires heat metering (hereafter referred to as HQR). Heat metering is mandatory for air/water heat pumps. Heat metering for brine/water and water/water heat pumps only have to be installed for a flow temperature ≥ 35 °C. The heat metering must record the total thermal energy released (heating and domestic hot water) in the building. In heat pumps with heat metering, the analysis is carried out by the regulator. The regulator displays the thermal energy discharged in the heating system in kWh.
OperationYour decision to purchase a heat pump or a heat pump system is a long-term contribution to protecting the environment through low emissions and reduced primary energy use.
You can operate and control the heat pump system with the control element of the heating and heat pump regulator.
NOTE Make sure that the control settings are cor-
rect.
Operating manual of the heating and heat pump regulator.
To ensure that your heat pump or heat pump system operates efficiently and ecologically, the following are especially important:
€ ENERGY SAVING TIP Avoid unnecessarily high flow temperatures. A lower flow temperature on the hot water
side increases the efficiency of the system.
€ ENERGY SAVING TIP Preferably use rapid ventilation. To save en-
ergy and reduce your heating costs, do not leave windows open for long periods.
Care of the unitThe outer surfaces of the unit can be cleaned with a damp cloth and household cleaning products.
Do not use cleaning or care products that contain abrasives, acids and/or chlorine. Such products would destroy the surfaces and could also damage the technical components of the unit.
