Standby mode In standby mode, the entire system is switched off and protected from frost (all frost-protection functions active).
C
Hot-water production is disabled and protected from frost. Application Total deactivation of heating and hot water with full building protection. The heat generator and hot-water production remain in operation in case of external demand or demand by other heating circuits on the bus network. The heating circuit pumps are switched on briefly every day (pump anti-blocking protection). The standby mode remains active until another operating mode is activated. Display Activated continuous standby mode appears in the basic display with the information STANDBY.

Holiday mode In holiday mode, the heating circuits can be switched off and protected from frost or operated based on the settings for the RED. 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. You can now enter additional holiday timeframes (up to 15 holiday blocks).

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. (current date + 250 days) An active holiday program appears in the basic display with information on the return date.

"System information" button Calls up system information, such as temperatures and counter data. 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.
