  • Page 9 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. Curve Inclination Primary Flow Temperature The inclination value which is set is the primary flow temperature when the outside temperature is –15 °C.
  • Page 10 Heating Summer season Primary Flow Temperature switched off ºC All properties have internal heat gains (lamps, oven, Heating up body heat, etc.), which means that the heating can be switched off when the outdoor temperature is lower than the desired room temperature. The better insulated the house is, the earlier the heating from the heat pump can be switched off.

  • Page 43: First Start

    12. First start When the heat pump is delivered, the compressor is blocked to avoid it being unintentionally started. The heat pump can be installed and started before the brine circuit is put into operation. The heat pump can also be started without a fitted room sensor. The set curve will then regulate the heating.

  • Page 44: Operation And Maintenance

    14. Troubleshooting/Appropriate measures The CTC EcoPart i600M is designed to provide reliable operation and high levels of comfort, as well as a long service life. If a fault occurs, you should always contact the installer who installed your unit. If the installer believes the malfunction is due to a materials or design fault, then they will contact Enertech AB to check and rectify the issue.

  • Page 45: System

    15. System 15.1 Heating circuit The CTC EcoPart i600M can control up to four heating circuits* using room sensors – for example, two radiator circuits and two underfloor heating circuits. The required curve inclination and adjustment are set when operating outdoor sensors (B15) only.
  • Page 46 15.1.1.1 More than two heat pumps The CTC EcoPart i600M and a CTC heat pump of another model can be HP 1 connected via 3-way valves to alternate the charge between the hot water tank and the heating circuit.
  • Page 47 15.1.1.2 Prioritisation of heat pump operation When the CTC EcoPart i600M is connected to the heating circuit along with heat 8 kW 12 kW pumps of different sizes, the heat pumps are divided into two categories: small or large heat pumps. Dividing the available heat pumps into two different size categories means it is possible to change the output in small steps and in this way achieve modulating operation.

  • Page 49: Solar Panels

    15.4 Solar panels* Solar panels can be connected to the buffer tank, DHW system and the bedrock/ground source heating circuit via 3-way valves. When the temperature rises and the temperature difference exceeds 7°C (factory setting) between the solar panels and the DHW tank, the charge pump starts and transfers the solar heat to the DHW system.

  • Page 50: Recharging Bedrock/Ground

    15.5 Recharging bedrock/ground* A 3-way valve can be installed in the solar circuit and connected to the brine circuit (the loop in the borehole or the ground heat loop) to recharge the bedrock/ground when the DHW tank/buffer tank are fully charged (factory set at 85 °C), or when the temperature in the solar panels is not sufficiently high to charge the tank but is able to provide an addition to the brine circuit.

  • Page 51: Cooling

    15.6 Cooling* Cooling – also called “natural cooling” or “passive cooling” – exploits the free cooling found in bedrock. A bedrock/ground source heat installation is easily supplemented with a fan convector, a circulation pump, pipe and pipe parts, e.g. CTC EcoComfort. Operating costs are very low as the cold itself does not need to be produced, instead being simply transferred from the bedrock to the house.

  • Page 177 22.2.7 Solar pumps (G30, G32)* The solar PWM pumps (G30 and G32) of model WILO Stratos PARA differ from the other PWM pumps. If the PWM control signal is interrupted, the solar pumps stop, whereas the other PWM pumps work at 100% power if the signal is interrupted.
  • Page 178 1. Briefly press the circulation pump arrow to show the operating mode to which the pump is set. After 2 seconds, the operational information screen will be displayed again. 2. Pressing the circulation pump arrow for 2 seconds will cause the LEDs to flash and the mode setting can then be changed.

  • Page 181 (B14) Room sensor 4, expansion card X4* block no. alarm output block no. input block no. Room sensors should be installed at head height in open areas of the property with good air flow and where a representative temperature can be expected (not close to sources of heat or cold).
  • Page 182 22.3.3 Primary flow sensor (B1, B2, B3*, B4*) The sensors sense the outgoing temperature to the radiators. Secure the primary flow sensor to the pipe using straps or similar. Most important is the position of the tip of the sensor as this is the part that detects the temperature. The sensor must be insulated to prevent the ambient temperature from affecting the measurement.
