SERVICETIME
NOTE! Only used for test operation. Simulates time 60 times as fast, which
means that the waiting times are eliminated during test operation.
0 = deactivates SERVICETIME
1 = activates SERVICETIME which speeds up the control computer’s integral cal-
culation and start delay by 60 times.
-
FACTORY SET
0 = starting point, the value returns to zero after a change
R = reset factory settings for radiator system
G = rest factory settings for under floor heating
-
RESET OPERAT. TIME
0 = no reset of operation times
1 = reset operation times to zero
-
CALIBRATION SENSOR
Following sensors are in the installation:
OUTDOOR

0 (interval: -5°C / 5°C)
-5°C (interval: -5°C / 5°C)
EXTERNAL INFLUENCE (these parameters affect all sensors except the outdoor
sensor. The parameter compensates for the external influence on the sensor that
is mounted in the heat pump.
0 (At AIR 5)
(interval: 0 / 20)
VERSION
Shows the software version which is stored on the display card respectively the
I/O-card.

LOGTIME
Time interval between collection points of temperature history in minutes. The
history graphs always show the 60 last collection points, which means that the
graphs can display history from 1 hour up to 60 hours ago.
(The function is not active if there is an active alarm).
1M (interval: 1M / 60M)
BRINE TIME ON
Switch on delay for compressor, in seconds.
30S (at internal passive
cooling 90S)
(interval: 10S / 90S)
BRINE TIME OFF
Switch off delay for brine pump, in seconds.
30S (interval: 10S / 60S)
TOPH. TIME
= Deactivates time period for peak heating charging (does not apply to system D).
ON = Activates time period for peak heating charging (does not apply to system D).
TOPH.TIME D
Time period to maintain peak heating charging temperature in hours (applies to
system D).
1H (interval: 1H / 10H)
Sub menu SERVICE -> DEFROST (
DHP-A, -AL
)
The menu applies to
DHP-A, -AL
with defroster card and only appears if OUTDOOR AIR in the SERVICE -> INSTALLATION -> SYSTEM -> HEAT

DEFR CURVE 0
The temperature of the heat pump’s brine return at which defrosting should
start, at 0°C outdoor temperature is set here, using + or -.
The graph can be changed up or down at 0°C outdoor temperature in the dis-
play. See section 12.9 for further information.
-10°C
(interval: -15°C / -5°C)
DEFR CURVE [value for
OUTDOOR STOP]
The temperature of the heat pump’s brine return line at which defrosting should
start, at the set outdoor temperature for OUTDOOR STOP is set using + or -.
The setting is made by reducing the OUTDOOR STOP value by this value.
The number of degrees shown after DEFR CURVE in the display is the set value
for OUTDOOR STOP. The combined temperature is shown in the top right corner
of the display.
The graph can be changed up or down at the outdoor temperature OUTDOOR
STOP in the display. See section 12.9 for more information.
EXTERIOR STOP reduced
by 4°C
(interval: -8°C / -1°C)
DEFR TEMPERATURE
The temperature shunted to the outdoor unit during a defrost.
15°C
(interval: 14°C / 20°C)
STOP DEFR
The temperature that must be reached in the Brine In sensor to complete a
defrost.
11°C (interval: 7°C / 12°C)
