Energy saving periods
In order to save electric power when the machine is not in use, this
function is used to lower the water temperature in the boiler and to
switch off the door light.
The energy saving function is enabled / disabled in ‘Set state’.
7 energy saving periods can be programmed on a weekly basis.
For each period a start day and time, and an end day and time must
be defined. The start and end days are identified by progressive
numbers: (Monday=0, Tuesday=1, etc.) and all weekdays (ALL=7).
This means:
• An energy saving period that crosses midnight requires two
period settings, see Example, periods 1 and 2.
• If the periods are set overlapping, the machine will be shut
down as long as it is covered by one of these periods, see.
Example: Period 3.
• The same time period cannot include days from different weeks,
i.e. a period cannot be set from Monday to Monday.
• A period cannot have a ‘start time’ later than the ‘end time’, see
Non Example 2.
• Non Examples 1 and 2 illustrate settings which will give
unintended results.
The temperature during the energy saving period is set in ‘set
temperature’
Example
The vending machine is to run Monday to Friday from 07:00 till
22:00. The remaining time of the week and during the weekend the
machine is set to energy saving. Three periods have to be set as
follows:
Non Example 1:
Non Example 2:
Period 1
Set start day ALL=7 Set start time 22:00
Set end day ALL=7 set end time 23:59
Result: The machine is ‘shut down’ every day from 22:00 till midnight the same
day.
Period 2
Set start day ALL=7 Set start time 00:00
Set end day ALL=7 set end time 07:00
Result: The machine is ‘shut down’ from midnight 00:00 till 07:00 in the morning
the same day.
Period 3
Set start day Fr=4 Set start time 22:00
Set end day Su=6 set end time 23:59
Result: The machine is shut down from Friday evening at 22:00 till Sunday
evening at 23:59.
Period 1
Set start day Mo=0 Set start time 22:00
Set end day Fr=4 set end time 07:00
Result: The machine is ‘shut down’ Monday at 22:00 till Friday at 07:00 which
was not the intention.
Period 1
Set start day All=7 Set start time 22:00
Set end day All=7 set end time 07:00
Result: The machine is not ‘shut down’ as the end time must not be earlier than
the start time for the same day or the setting ‘ALL’.
