1.1 Equipment description 1.2.2 With the control flap open and with all indicator elements on display The FEK control module only works in conjunction with the weather-compensated WPMi control unit. It enables the convenient entry and display of system parameters, e.g.
Closing Application: In low energy houses without the control flap with illuminated indicator setback mode. returns the FEK into its original position. The modified value will then not be saved. Constant setback mode The heating circuit is held at constant setback temperature.

After you press this key, the first display is 1.5.2 Away key the outside temperature. Continuing to press displays, in sequence, the actual DHW This key activates the eco mode (away). temperature, the actual return temperature, Press twice: The heating circuit switches to the maximum and minimum room setback mode for one hour.

1.5.5 Overview of system parameter (control level 2) Select the required parameter with the rotary selector. For adjustments to parameters, turn to page 6. With the Room temp. parameter you can adjust the set ROOM T room temperature of the heating circuit for the day and setback mode.

SET HIGHT The heating curve, room temperature and heating program parameters are not shown at the WPMi heat pump manager, if the FEK is pre-selected for a specific heating circuit. SET HIGHT Room temperature With the Room temp. parameters you can adjust the set room temperature for the day and setback mode.

Open the control flap At all other times, the heat pump operates in setback mode. You will already have selected the corresponding set values for day TEMPERATURES and setback mode under the Room temp. parameter. Example: Your heating system should operate daily from Monday to Friday at two different times, i.e.

Heating curve The Heating curve parameter allows you to select a heating curve for heating circuit 1 or 2. Selecting the correct heating curve is vitally important. Note: Your contractor will have set up a building and system-specific optimum heating curve for the heating circuit.

Open the control flap HTG CURVE BACK Heating curve diagram One heating curve respectively can be adjusted for heating circuit 1 and heating circuit 2. At the factory, heating curve 0.6 is set up for heating circuit 1 and heating curve 0.2 for heating circuit 2.

Adjustment of programmed changeover between day/setback mode The figure shows a standard heating curve with a slope of 0.8, relative to a set room temperature for day mode of 20 °C. The lower curve represents the setback curve. For this, a set room temperature for setback mode of 15 °C is used, in other words the heating curve is subjected to a parallel offset.
22 01 93 Dimensions: 147 x 97 x 33 (mm) 2.2 General information The FEK is vitally important for area cooling, e.g. underfloor heating systems, area heating etc. Apart from the room temperature, it also determines the relative humidity to prevent condensation.
Checking settings does not require the code to be determined as part of commissioning the be entered. FEK. These parameters are adjusted at control level 3, access to which is protected by code. Language To reach this point, press , until you reach the “Contractor”...

Incorrectly set heating curves are corrected the FEK control module by ±5 K. This set value by the room temperature sensor influence adjustment applies for the then current heating K, whilst the smaller factor K provides more time, not for the setback time.
