Operation 4 4.7 Editing screens (examples) 4.7.1 Entering time programmes (example for heating) Using the time programmes you can allocate up to three time windows per weekday, or block of days (e.g. Mo - Fr). In these time windows, the heating system maintains the room temperature that you have selected, the so-called comfort temperature. Outside the time windows, the room temperature is set back. The set-back temperature can also be changed.
4 Operation Enter the room temperature as follows: h Note The same procedure as shown in the example for heating circuit applies when inputting the time programme for hot water generation or for a circulation pump. A comfort temperature does not need to be entered for hot water generation and the circulation pump. 4.7.2 Programming holiday periods For a longer period of time when you are not at home, you can define a lower room temperature. This will save heating energy.
Operation 4 4.7.4 Entering the parameters for hot water generation If the hot water for your home is generated by the appliance the target temperature can be entered via the VRT 392f. Click the right-hand dial. The character is inversely displayed. Turn the right-hand dial to select the correct letter or number. Click the right-hand dial. Turn the left-hand dial until you reach Screen "Hot water parameters". 10 The cursor is positioned in front of the value for the target temperature.
5 Status and error messages 5 Status and error messages Status and error messages are displayed in the second row of the field for basic data. This is how to do it: Pull the controller (1) off the wall socket (2). This can be done by pushing a screwdriver into the two retaining straps (see Fig. 5.1 arrows). Status messages 1 Holiday Within a set holiday time period the heating is controlled to the room set target temperature for this period.
