OperatingmodeMeaningADD. HEATER The control system only permits the auxiliary heater to bein operation.HOT WATER In this mode the heat pump only produces hot water, noheat goes to the heating system.Caution! If the operating mode OFF or HOT WATER is to beused for long periods during the winter, the water in theheating system in the heating system must be drained,otherwise there is a risk of frost damage.5.2 Adjusting the indoor temperatureThe indoor temperature is adjusted by changing the heat pump’s heatcurve, which is the control system’s tool for calculating what the supplytemperature should be for water that is sent out in the heating system.The heat curve is a graph that compares the outdoor temperature withthe supply temperature. The colder the outdoor temperature the moreheat is supplied to the heating system. The heat curve will be adjustedin connection with installation. It must be adapted later on, however, toobtain a pleasant indoor temperature in any weather conditions. A cor-rectly set heat curve reduces maintenance and saves energy.There are two ways of adjusting the heat curve, partly in the HEATCURVE sub-menu, partly with the ROOM value.Adjusting the HEAT CURVEA typical heat curve is shown below. At an outdoor temperature of 0°Cthe supply temperature should be 40°C. At outdoor temperatures colderthan 0°C, supply water hotter than 40°C is sent out to the radiators andat outdoor temperatures greater than 0°C, supply water cooler than40°C is sent out. When you increase the CURVE value, the heat curve willbecome steeper and when you reduce it, it will become flatter.16 – User manual VUBMA902 |
