Page 8: Your Home's Heating Installation
General Information Your home's heating installation The House Heating Curve The heating curve is the central part of the product’s control system. It is the heating curve which determines the compensated flow temperature requirements for your property dependent upon the outdoor temperatures. It is important that the heating curve is correctly adjusted, so that you achieve the best operation and economy possible. - Page 9 General Information Adjusting the heating curve The method described below can be used to adjust the heating curve correctly. Adjustment if it is too cold indoors • If the outdoor temperature is lower than 0 degrees: Increase the Inclination value by a couple of degrees. Wait 24 hours to see if any further adjustment is required.
- Page 10 General Information Examples of Heating Curves You can see in the diagram below how the heating curve changes with different Inclination settings. The gradient of the curve shows the temperatures that the radiators require at different outdoor temperatures. Primary Flow Temperature Curve Inclination The inclination value which is set is the primary flow temperature when the outside temperature is –15 °C.

Installation Circulation pump for radiator system (36) (37) The circulation pump is fitted on the heat pump's primary flow and must be connected electrically from the boiler, see chapter on Electrical installation. Mixing valve DHW (65) Install a mixing valve for the hot tap water in order to avoid the risk of scalding. Safety valve DHW (93) Fit the enclosed valve to the incoming cold water connection. -
Page 45: Product
Installation Operation without a brine system EcoHeat can be used without the brine system's cold side being connected. The heat pump then operates like a normal electric boiler with its control system providing full functionality. However, the DHW capacity is slightly lower as only the upper part of the tank is heated. -
Page 46: Pressure Drop
Installation Pressure drop Pressure drop in mixing valve The diagram below shows a drop in pressure in the mixing valve. Start with the heat requirement in kW (e.g. 15 kW), then move vertically to the selected ∆t (e.g. 10 °C). Then move horizontally to the line for the EcoHeat mixing valve = line 6.3 DN20. -
Page 47: Connecting The Brine System
Installation 10. Connecting the brine system The brine system, i.e. the ground collector loop, must be assembled and connected by a qualified tradesman in accordance with current regulations and design guidelines. We recommend that you follow Extreme care must be taken to ensure that no dirt gets on the collector hoses, the installation which must be washed clean before being connected. - Page 48 Installation Valves You fit the valves as shown in the schematic diagram on the next page. To facilitate servicing of the cooling unit, shut-off valves should be fitted to both the incoming and outgoing connections. Fit bifurcated valves so that you can fill and bleed the collector circuit later on.
