  • Page 27: Installing Instructions

    Installing instructions Installing the sensor(s) Correct arrangement and installation of the sensors is extremely important for correct func- tioning of the system. It should be ascertained that the sensors are completely inserted in the immersion sleeves. The threaded cable connections can serve as strain relief. Fundamentally sensors should not be exposed to moisture (such as condensation) since this can diffuse through the cast resin and damage the sensor.

  • Page 28: Installing The Unit

    Installing the unit CAUTION! ALWAYS PULL THE MAINS PLUG BEFORE OPENING THE CASE! Unscrew the 4 screws at the edges of the case. The controlling electronic is situated in the cover plate and is connected by a ribbon cable to the mains module, which is set in the basin of the case.

  • Page 36: Basic Principle Of Heat Curve

    Basic principle of heat curve This principle allows automatic temperature control of the heating circuit flow temperature depending on outdoor and room temperature. Description: By setting the values T+20 and T-20 it is possible to set the flow temperature of heating circuit, measured at T4 (flow temperature sensor).

  • Page 37: Setting The Time Switch Function

    Setting the time switch function As soon a time program is allocated to the heating circuit output A1 this function allows normal heating mode only within the switch- on and switch-off times. I.e. the function switch- es over between normal heating and lowered mode. This function mode acts only on heat circuit with output A1.

  • Page 47: After-Running Time Pnl

    After-running time PnL During the start phase, the pumps may repeatedly switch on and off for a long time, espe- cially with solar and heating systems with long hydraulic system lines. This response can be reduced by using a speed control or increasing the pump after-run time. Depending on the selected program each output can be allocated an after-running time, except mixer outputs.

  • Page 48: Switching Hystereses Hst

    Switching hystereses HSt Switching hysteresis is the difference between switch-on and switch-off temperature. I.e. a thermostat set to 70°C with 10K hysteresis switches off at 70°C and on at 60°C. Hystereses are not constant, but change with measured temperature. Setting range is be- tween1 to 9K per 64°C.
