▪ Water expands when it is heated, which means that a small amount of water is released from the system via the overflow pipe. ▪ The water that exits the overflow pipe can be hot! Therefore, allow it to flow to a floor drain to prevent any risk of burning yourself. Danfoss Heating Solutions VUMIB102... -
Page 8: About Your Heat Pump
About your heat pump Product description The DHP-M heat pump is a heating system for heating and, if an external water heater is installed (accessory), for hot water production. It has a compressor which is customised for heat pumps. The DHP-M heat pump is equipped with control equipment which is presented in a graphic display. The control equipment is also prepared for monitoring via the internet. -

Page 11: Settings And Adjustments
A correctly set heat curve reduces the need for maintenance, as well as making operation more energy-effi- cient. The indoor temperature is adjusted by changing the heat curve of the heat pump. This curve is the control system's tool for calculating the correct supply temperature of water for the heating system. Danfoss Heating Solutions VUMIB102... -

Page 20: Checking The Brine Circuit Pressure
The brine circuit must be filled with the correct amount of fluid; otherwise the installation may become dam- aged. Ensure that the system has the necessary pressure, but not above the maximum pressure of 6 bar. For filling brine, see the commissioning guide. VUMIB102 Danfoss Heating Solutions... -
Page 21: Check The Water Level In The Heating Circuit
In case of doubt, contact your installer. NOTE: Do not use any additives for treatment of the water in the heating system, unless you have a written consent from Danfoss! Checking safety valves The safety valves for the installation must be checked at least four times a year to prevent lime deposits clog- ging the mechanism. -

Page 26: Calculating Heat Production
To ensure that the supply line temperature is not too warm (or cold) for the heating system, max and min sup- ply line temperature boundaries should be set. See chapter Heating Settings (Supply line min and max) in this appendix. The simplified working principle for the heat curve is as follows: VUMIB102 Danfoss Heating Solutions... - Page 27 If the curve is moved upwards, the heat curve will become steeper and if the curve is moved downwards, it will become flatter. The most energy efficient and cost effective setting is achieved by changing the curve settings which leads to fewer starts and longer operating times. Danfoss Heating Solutions VUMIB102...
