Meaning
Factory setting
START
Start temperature for hot water production. Shows the actual weigh-
ted hot water temperature and the value within brackets indicates
the start temperature. (
= no sensor alarm)
(range:
, 30°C / 55°C)
HOT WATER TIME
Time for hot water production during combined hot water and heat-
ing demand, in minutes.
20M
(range: 5M / 40M)
TOPH. TIME
Time in hours that the legionella demand is to be fulfilled for legion-
ella operation to be considered complete.
0M
(range: 1M / 10M
HEATING TIME
Time for hot water production during combined heating and hot
water demand, in minutes.
20M
(range: 5M / 40M)
TOPH. INTERVAL
Time interval between peak heating chargings (anti-legionella func-
tion) in days. Operating mode that permits auxiliary heater must be
selected.
7D
(range:
, 1D / 90D)
TOPH. STOP
Stop temperature for peak heat charging. Operating mode that per-
mits auxiliary heater must be selected.
60°C
(range: 50°C / 65°C)
INFL. H.W SENSOR.
Water heater sensor’s influence compared with the peak sensor’s at
start of water heating.
65%
(range: 0% / 100%)
WEIGHT HOT WATER
The calculated value of the hot water sensor directed towards the
peak sensor.

Meaning
Factory setting
INTEGRAL A1
The integral’s value for starting the heat pump. See Important
parameters for more information.
-60°min
(range: -250°in / -5°in)
HYSTERESIS
If the difference between the actual supply temperature and the
calculated supply temperature is too great either the integral
value is set to start value A1 (the heat pump starts) or the value is
set to 0 (stops the heat pump).
12°C
(range: 1°C / 15°C)
MAX RETURN
Stop temperature at high return from the heating system.
55°C
(range: 30°C / 70°C)
START INTERVAL
Minimum time interval between two heat pump starts in minutes. 20M
(range: 10M / 30M)
ALARM BRINE
Gives an alarm when the outgoing brine temperature falls below
the set value.
(range:
, -14°C / 10°C)
PRESS. PIPE
Sensor on the compressor’s hot gas line. Value within brackets
indicates maximum permitted temperature. If this value is excee-
ded, the compressor will stop and start again as soon as the tem-
perature has dropped. No alarm shown in the display, however, a
square is shown in the left, lower corner of the display.
140°C
SHUNT TIME
Time in seconds. Indicates how often the shunt is to adjust its
opening.
60S
(range: 10S / 99S
SHUNT COOLING
The cooling shunt works towards the set temperature.
18°C
(range: 0°C / 30°C)
