Set point value calculation
The set point value for the heating circuit is the current curve value
adjusted with active curve influence, if any such exists.
Priority order for curve influence is:
•
External control
•
Active program
•
Holiday
Only one of these can be active. How big the influence should be and
when to exercise it is set in the respective function.
Fixed set point value
A fixed set point value (not curve-based) applies in the event of:
• External set point value. The set point value is determined according
to input signal 0-10V where 1V is 10 °C and 10V is 80 °C (0V triggers
an alarm).
Set point value limitation
The calculated set point value is always checked against the permitted
temperature limits.
The applicable set point value T1 for
Circuit 1
and the measured actual
value for T1 are used to activate and deactivate the heat demand.
The following applies to
Circuit 2, 3...
: When the actual value for the
mixed circuit's T1 is low in relation to the set point value, more heating
water is shunted into the circuit so as to maintain the set point value.
If the flow temperature has been below the set point value for a certain
period of time, there is heat demand and the compressor produces heat
before there is a too significant temperature reduction indoors. This
happens until the flow temperature is a couple of degrees higher than
the set point value. (Or because
Maximum operating time for heating
at hot water demand
has passed.)
Heating demand is not active during summer operation.
1.10 General
1.10.1 Summer/winter time
1.10.1.1 Winter operation
If
On
is selected, the heat pump is constantly in winter operation and
heat and hot water are always produced.
Off
signifies constant summer
operation; only hot water is produced.
Automatic
signifies change-over
at the set outdoor temperature.

Hot water program
2.2 Hot water mode
▶ Select hot water mode.
Economy
means that the hot water is permitted to cool slightly
before hot water production starts compared to
Comfort
. Heating
stops at a slightly lower temperature.
▶ Change to
Comfort
If more or hotter hot water is desired.
This setting must be used if electric additional heat is missing or if the
hot water circulation is used, when the temperature in the hot water
circulation is otherwise too low.
The factory settings for on and off temperature are approx. 8 K ( °C)
lower in Economy mode compared to Comfort mode. These values can
be adjusted by the installer.
2.3 Extra hot water
Additional amount of hot water is produced by temporarily increasing
the temperature of the hot water during the set number of hours to the
indicated stop temperature.
2.3.1 Extra hot water duration
▶ Set the duration of extra hot water production.
2.3.2 Extra hot water stop temperature
▶ Set the stop temperature for extra hot water.
The heat pump starts the function directly and uses the compressor first
and then the additional heat source to increase the temperature. When
the desired number of hours have passed, the heat pump returns to
normal hot water mode.
2.4 Hot water peak
Hot water peak
means a temporary increase in the hot water
temperature to approx. 65 °C for thermal elimination of bacteria
(pasteurisation).
For the hot water temperature increase, the compressor is used first;
the additional heat source then continues alone.
2.4.1 Day of the week
▶ Set the day when hot water peak should happen.
None
means that
the function is deactivated.
All
means that a hot water peak takes
place every day.
If hot water peak is deactivated comfort mode must be selected in the
menu
2.2 Hot water mode
.
2.4.2 Interval in weeks
▶ Set how often a hot water peak should take place.
– 1 means a hot water peak every week.
– 2 means that a hot water peak takes place in all even weeks of the
year, i.e., in week 2, 4, 6, etc.
– 3 means week 3, 6, 9, etc.
– 4 means week 4, 8, 12, etc.
2.4.3 Start time
▶ Set time for the hot water peak.
2.5 Hot water program
Program 1
and
Program 2
enables you to block hot water production
during the set time.
2.5.1 Active program

Programs are changed in the same way as for

Room
temperature program
.
In the event of alternation between winter and summer
operation and vice versa, there is a certain delay aimed
at preventing constant starting and stopping of the
compressor when the outdoor temperature oscillates
around the temperature limit.
DANGER:
Risk of burn injuries.
▶ Use a mixing valve when the hot water temperature
exceeds 60 °C.
WARNING:
Risk of scalding.
At hot water temperatures greater than 60 °C, there is a
risk of scalding.
▶ Exercise caution when using hot water immediately
after a hot water peak.
