3.3.6 System – time and date
In the menu "timers/timer service", the system clock of the HPM controller can be
set. To set the clock, press "OK" starting from the default menu. Press "OK" again to
enter the menu "timers". Use "DOWN" to select "timer service" and enter this
menu by pressing "OK". This menu contains the menu items "time" and "date".
In these menus the parameters "curTime" (current time) and "curDate" (current
date) are available for selection and modification. The values can be adjusted using
"+" ,"-" and a new value entered with "OK".
To ensure that the occupation times for domestic hot water and the heating circuits
will function correctly, entering the correct values for the system clock is essential. If
the system clock uses an incorrect value, wrong temperature reductions may occur
during the night or during holidays.
3.3.7 Occupation times
Each consumer circuit (domestic hot water, heating circuit 1, heating circuit 2) and
the "whisper (i.e. quiet) mode" of the heat pump (only usable when communicating
via bus) has an assigned timer. After the system diagram has been loaded, all timers
are set to the occupation time "mon-sun: 00:00 – 24:00 o'clock". Using this setting,
no temperature reduction will take place for the domestic hot water and heating
circuits during the night. The heat pump will also not automatically switch to
"whisper mode".
If temperature reductions are to be used during the night, these settings can be
changed in the menus "DHM", "heatc.1", "heatc.2", "quiet", after selecting the timer
channel in the menu "timers / timer chan.select". Up to 4 occupation times can be set
per day, with an option to use occupation times for a group of days in the same week.
In the weekly timer programs, the beginning and end time of the occupation times are
not permitted to overlap. Occupation times that exceed the end of a day must be
programmed using 2 occupation times (numOT=2; 1:18-24 o'clock; 2:0-6 o'clock)
The annual programs for the timers permit setting special non-occupation times (max.
15) and special occupation times (max. 10). Depending on the date, it is possible to
set operating times that differ from the normal non-occupation times (e.g. holiday in a
private house) and normal occupation times (e.g. a normal weekday in a school). For
annually recurring special days, the year may be set to "--" (e.g. 01.01.--).
The timer menu is opened by pressing "OK" twice before the display shows the
default display. Use "DOWN" to select the channel selection "timer chan.selec." and
press "OK". Select the desired timer using "DOWN" and press "OK" to enter. From
here, the menu items "weekly program", "special non-occupation time" or "special
occupation time", can be selected as desired, containing the aforementioned
parameters.
