  • Page 5 Congratulations on your new product You have just purchased a CTC GSi 600, with which we the floor circuits. Using the integrated night reduction hope you will be very pleased. Read about how you can function, you can set and change the temperature in the house throughout the day, from one day to the next.

  • Page 6: Important! Information On Air Bleeding

    Important! Information on air bleeding For the product to work as intended, the system must be fully bled. It is extremely important that a basic bleeding of the product is carried out systematically and carefully. Bleeding devices must be fi tted to the system’s natural high points. A basic bleeding of the hot water tank can be carried out upon installation by releasing the safety valve, which must be fi tted to the top of the product.

  • Page 7: Safety Instructions

    Safety instructions Turn off the power with an omnipolar switch before doing any work on the product. The product must be connected to protective earth. The product is classified as IPX1. The product must not be rinsed with water. When handling the product with a hoist ring or similar device, make sure that the lifting equipment, eyebolts and other parts are not damaged.

  • Page 8: Your Home's Heating Settings

    Your home’s heating settings 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 Appropriate Default Values During installation you can seldom achieve a precise setting for the heating curve instantly. In this case, the values given below may provide a good starting point. Radiators with small heat-emission surfaces require a higher primary flow temperature. You can adjust the gradient (heating curve gradient) for your heating system under the "Installer / Settings / Radiator system"...
  • Page 10 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.
  • Page 11 Summer-time operation Primary Flow Temperature Heating All properties have internal heat gains (lamps, oven, ºC switched body heat, etc.), which means that the heating can be Heating up Heating up 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.
