There will be an uncertainty of -+3%
when using manually setting of days.
21 days = +- 0.6 days
50 days= +- 1.5 days
99 days= +- 3.0 days
Do not use an external timer to cut the
power supply, use instead the externally
controlled DHW production, by wiring the
external potential free contact to termi-
nal block CN5 connector 5 and 6. “See
page 18 - Electrical installation, for wiring
diagram”.
The external contact or timer must have
gold-plated contacts due to low current
operation. When the contact is “closed”
the DHW production is locked, while the
frost protection is activated. When the
contact is open, the DHW HP operates in
the selected operating mode.
USE OF HOLIDAY FUNCTION
With the use of the holiday function you are able to lower
the power consumption during your holiday and absence
from home. When activated, the hot water production will be
locked unless the DHW temperature is equal to “
T2min
”. At
the “
T2min
” temperature level the HP will resume working, in
order to protect the device and the installation against frost.
Should the temperature fall below “
T2min
” -1°C, the
supplementary heating will be released. If the temperature falls
further below “
T2min
” -3°C the heat pump will also start. When
the temperature reaches “
T2min
” +1°C the DHW production
will be locked again.
The “
holiday
” parameter menu has 5 possible choices:
•
1 week
•
2 weeks
•
3 weeks
•
3 days, for an extra-long weekend
•
Manually setting of days (1 – 99)*
USE OF BOOST FUNCTION
The “
Boost
” mode gives you the possibility to generate DHW
faster and in excess quantity in the case of urgent or
occasional need for DHW (family visit, the sports team of your
children comes for a shower, etc.) To activate the “
Boost
”
cycle, select the menu parameter “
Boost
” and the value “
on
”.
During the “
Boost
” cycle the HP and the supplementary
heating will operate simultaneously for 1 hour maximum or
until “
Tmax
” is reached. If you still need more DHW you have
to activate the “
boost
” function again.
USE OF EXTERNALLY CONTROLLED DHW
PRODUCTION
You can control the DHW production externally by means of
a potential free contact (energy counter, external timer, etc.).
This function gives you the possibility to generate DHW in a
specific period (e.g. off-peak tariff production, acoustic comfort
preference, etc.).
This configuration is needed if you have
software version 1.58 - 1.61 only.
Do not use for software version 1.62 - 1.65
At the “
T2min
” temperature level the HP will resume working,
in order to protect the device and the installation against frost.
Should the temperature fall below “
T2 min
” -1°C, the
supplementary heating will be released. If the temperature falls
further below “
T2 min
” -3°C the heat pump will also start.
When the temperature reaches “
T2 min
” +1°C the DHW
production will be locked again.
