10.3.3 Cooling mode without winter-shut-off
The diagram in the figure below, labelled Cooling mode
without winter shut-off, illustrates an operation example
with the following setup:
• Operating mode is set to cooling, see section 8.9.1 Operating
mode (select), page 31
• Winter shut-off is not defined
Period P1: During this period, which covers the full year, the
circulation pump is running continuously.
10.3.4 Cooling mode with winter-shut-off
The diagram in the figure below, labelled Cooling mode
with winter shut-off, illustrates an operation example
with the following setup:
• Operating mode is set to cooling, see section 8.9.1 Operating
mode (select), page 31
• Winter shut-off is set up for the colder period of the year. See
section Winter shut-off, page 29 for instructions on how to
define the shut-off period.
Period P1: During this period, which in this example covers the
months April to August, the circulation pump is running
continuously.
Period P2, winter shut-off: During this period, which in this
example covers the months September to March, the following
scheme applies:
1. When the period P2 starts, the circulation pump is running
continuously.
2. When all conditions for winter shut-off are met, the mixing
valve closes and the circulation pump stops.
Shut-off conditions:
• The winter shut-off date is passed, for example
1 September.
• The outdoor temperature has fallen below the cooling
deactivation limit, for example 22°C
• The delay period for the deactivation temperature has
expired, for example 24 hours
3. In case there is a brief period with warmer weather during the
winter shut-off period, the system automatically turns on
again with cooling supplied and circulation pump running.
Turn-on conditions:
• The outdoor temperature has risen above the cooling
activation limit, in this example 23°C
Note that the system uses a temperature hysteresis of
1°C between activation (for example 23°C) and
deactivation (for example 22°C)
• The delay period for the activation temperature has
expired, in this example 24 hours
4. The system will shut off again when conditions are met as
described in step 2. above.
5. When the end date of the winter shut-off period is passed,
the system turns on again when the turn-on conditions are
met, see step 3. above.
