Page 3: General Information Before Starting Installation
Nilan dealer, by visiting The product is controlled by an CTS 700 control system, which provides a wide range of functions. Compact P is a heat recovery ventilation system with a capacity of up to 330m /h at 100Pa exter- nal counter pressure. -
Page 4: Safety
Safety Always disconnect the electrical supply to the heat pump if any malfunction occurs that cannot be remedied via the control unit. If any malfunction arises on the electrical part of the heat pump, always contact a licensed electrician to repair the fault. Avoid direct contact with the heating system pipes in the heat pump, as they can be very hot. -
Page 5: Compact P
Compact P The function The installation of the plant must be performed by an authorized service technician or a field engineer who knows about heat pumps. Electrical installation/power supply (incl. Safety switch) must be installed by a certified electrician. The plant is connected according to the circuit diagram. -
Page 6: Installing Compact P
Installing Compact P When installing the unit, it is important to take future service and maintenance into ac- count. There should be a minimum clearance of 60 cm in front of the unit, measured from the Compact P front panel. ... - Page 7 Figur 3: Sketch of Compact P The unit must be installed and leveled on a firm, vibration-free surface. There should be at least 10mm clearance to walls or other permanent installations. Although the unit itself is practically noise and vibration free, care must be taken to prevent any vibration from being propagated to ad- joining parts of the building.

Supplementary heating element DHW The hot water tank has a supplementary heating element of 1,5kW. The heating element can be activated and de-activated via the CTS 700 control, see the “Settings → Compac → DHW settings” menu. The temperature, at which the heating element should be active (T11), can be set in the “Settings →... -
Page 15: Fault Finding
If problems arise during operation, please check the following before calling the service centre. Check that the alarm mark on the CTS 700 panel is displayed. If so, investigate the cause of the alarm and remedy the fault. If necessary, contact your local service centre. For details of alarms and how to reset them, please refer to the operating instructions for the CTS 700 controls. -
Page 16: Operation And Maintenance
The filters should be cleaned and renewed when needed. Usually the filters need to be renewed once every 3 month. The filter guard in the CTS 700 control can be used in order to make sure that the filters are checked. The filters can be cleaned by vacuuming or shaking them. - Page 17 Tilbehør Zubehör Accessories Accessoires Figur 10: Safety Switch Page 17 of 40 reserve the right to make changes...

Page 22: Pressure In Ground Source Loop (Ground Pipe)
Pressure in ground source loop (ground pipe) The pressure must be inspected as often as several times a day in the initial days. If necessary, the system must be topped up with brine. See Figure 13, point 17 Brine pressure will stabilise after a few days and inspection can then be reduced to once a month. It is important that brine pressure is correct. -

Page 24: Function Description
Function Description Heat pump compressor The system is protected with high and low-pressure switches that can stop the compressor and trigger an alarm. By heating demand the heat pump compressor starts when the temperature has dropped to set- point minus the neutral zone. When the compressor is operating the central heating temperature is raised up to the respective set point before it goes out. -
Page 25: Permitted Area Of Action For The Heat Pump
Make sure that the central heating system (e.g. the central floor heating system) is applied on a potential free input on CTS 700 to start/stop the heat pump. If input is not applied CTS 700 solely has to operate the heat pump. The central floor heating control must not start/stop the central heating pump directly! Mentioned below are examples using pump graphs for a Grundfos Alpha pump with different instal- lations of the pump control. - Page 26 Fixed pace: Run step 3 or a constant RPM control in the step that secures a circulation at a mini- mum of 20% of the design flow when there is not a heating need from the central heating system. Auto. Can be used if there is a fixed circulation. Do not work for a pressure controlled circulation valve.

Page 27: Frost Protection
Frost protection A number of functions are built into the system to prevent frost damage. These functions are al- ways active regardless of the operating modes and settings selected (including OFF). Any missing or defective temperature sensors or system components can of course render this protection inef- fective: When the outside temperature falls below 2 °C, the central heating circulation pump will start. -
