User manual BOSCH TR 200

[. . . ] English Correct function of this appliance can only be guaranteed if these instructions are observed. The regulator is to be used only in connection with the listed gas heating units. Before installing the regulator, the voltage supply (230 V, 50 Hz) to the heating unit must be interrupted. Sor is of advantage when the mounting location of the regulator is not suited for measurement of temperature (see chapter 4). [. . . ] Briefly depressing the button alters the starting time by 10 minutes, when the button is depressed for a longer period the time runs faster forward or backward. Now the respective first starting time for economic operation must be set. The display (e) shows: When the required starting times are programmed depress the button (q). Briefly depressing the button alters the starting time for economic operation by 10 minutes, when the button is depressed for a longer period the time runs faster forward or backward. As soon as the required starting time for economic operation is selected depress the button (q). If the programme for one single day was altered after having programmed all days of the week, the display shows --:-- at all starting times when the programme "All days" is recalled. If one starting time is now altered for all days of the week, the original programme for the various days is deleted and must be re-programmed as described above. --:-- means that this starting time was Only one starting time for heating operation and one for economic operation is programmed at initial operation (factory pre-setting) or after a longer power failure. If required, the second starting time for heating operation can now be set as described above, in the chapter "setting the first starting time". For the second starting time for economic operation, as well as for the third starting times for heating and economic operation (if required), please proceed as before. In case that certain starting times are not required, depress the button (q) without making any alterations. If a displayed starting time is to be cancelled, briefly depress the cancel button C (r) with the tip of a pen. Tip The various starting times for one day do not have to be entered in chronological sequence. In the mode Select day +/- the regulator arranges the starting times independently. You can check the programmed starting times by proceeding as described above, but without depressing "­" (o) or "+" (p). if the heating operation is to exceed midnight , the last economic operation is ignored. Enter this starting time as first starting time for economic operation on the following day. The regulator recognises the correct sequence of the starting times although the first starting time for heating operation is set to a later hour than the first starting time for economic operation. Should there be a day on which no heating operation is required (permanently, e. Office which is not busy on Sundays), please enter the required starting time for economic operation (if necessary, the day before) and cancel all further starting times up to the time you wish normal heating operation to commence. If on one day of the week continuous heating operation is required, please enter the required starting time for heating operation (if necessary, the day before) and cancel all further starting times up to the time you wish economic operation to commence. If you wish to carry out extensive alterations to the programme, it might be better to start off with the programme pre-set by the factory. [. . . ] If all settings, even the time and the day (and the display language) are to be deleted together with the starting times, the cancel button C (r) must be depressed for longer than 10 seconds. It is not recommended to let the temperature of daily heated rooms drop below +15°C. When the room is heated up again the comfortableness is diminished by the walls which are cooled down. So if one wants a real comfortable room temperature the regulator must be turned up and so a lot more energy is used up than is in case of an even heat supply. [. . . ]
