HEATING operating mode for the duration of the holiday based on the presetting ("Direct circuit" or "Mixed heating circuit 1" / "Mixed heating circuit 2" menu, parameter 25 = holiday operating mode). Setting Press button. The menu-selection level Switching time programs / Holiday programs appears in the display. The day on which the holiday is to begin flashes in the display. Set the day the holiday will begin with the input button . Set the day you will return from holiday with the input button . You can now enter additional holiday timeframes (up to 15 holiday blocks). Application Longer absence while heating operation is active. 24 EN2H-0220GE51 R0308 SDC / DHC Operation Control during holidays At outside temperatures below the frost-protection limit (see 4. 2. 3 "System Parameters" menu, pg. 51) the heating circuits are controlled as follows: Without wall devices: Based on a lowered room temperature specification of 3 C. With wall devices: Based on the room frost-protection limit of the respective heating circuit of 10 C (see "Direct Heating Circuit" or "Mixed Heating Circuit 1", "Mixed heating circuit 2" menu, parameter 08 = room frost-protection limit). Cancellation An active holiday program can be cancelled in case of early return. Press button. Turn input button and switch to automatic mode. The active holiday program has been cancelled. Factory setting Setting range Display Current date Current date. . . (current date + 250 days) An active holiday program appears in the basic display with information on the return date.

The information on the outside temperature appears first after the button is pressed. Turning the input button causes the system temperatures and the counter and consumption states and operating states of the connected system components to appear. Pressing the input button causes the respective setpoint values to appear. Exceptions Collector flow temperature: Solar tank temperature: Outside temperature: NOTE No setpoint No setpoint Averaged value The displayed information (see the following example) is independent of the installed or enabled system components and control circuits. 26 EN2H-0220GE51 R0308 SDC / DHC Operation Operating overview Press Turn input button to the left button Turn input button to the right Average/current outside temperature value Program/operating mode direct heating circuit/pump status Outside temperature min.

With this parameter, the time it takes for automatic return to the basic display can be specified. Setting range OFF No return. The last selected information display continuously remains in the basic display until the next change. Automatic return from the information level after the specified time (in 0. 5 minute increments). 1 . . . [. . . ] The maximum heat generator temperature is not functional. The heating circuit pump is switched off after a delay to avoid safety deactivation by reheating the heat generator (pump follow-up). If the outside temperature is or becomes lower than the specified outside temperature frost-protection limit, the controller switches from deactivated (deactivation mode) to lowered lowering operation and controls the heating circuit temperature based on the set lowering curve taking the set minimum heat generator specification into account. Application NOTE Building with high insulation values (full heating protection). [. . . ]
