Program settings
Program setting of ACS 45 can be performed via the
start guide or directly in the menu system.
START GUIDE
The start guide appears at first start-up after heat pump
installation, but can also be found in menu 7.7.
MENU SYSTEM
If you do not make all settings via the start guide, or if
you need to change any of the settings, this can be done
in the menu system.
MENU 7.2.1 - ADD/REMOVE ACCESSORIES
Add or remove accessories here.
Select: "Passive/active cooling 4-pipe".
MENU 1.1 - TEMPERATURE
Menu 1.1 Temperature
You make temperature settings for your installation here.
MENU 1.1.2 - COOLING
Set the temperature (with room sensor installed
and activated):
Setting range: 5 – 35°C
The value in the display appears as a temperature in °C
if the climate system is controlled by a room sensor.
Caution
A slow climate system, such as underfloor
heating, may be unsuitable for controlling with
room sensors.
Setting the temperature (without room sensors
activated):
Setting range: -10 to +10
The display shows the set value for heating/cooling
(curve offset). To increase or reduce the indoor temper-
ature, increase or reduce the value in the display.
The number of steps the value has to be changed in
order to achieve a one degree change to the indoor
temperature depends on the climate system. One step
is usually enough, but in some cases several steps may
be required.
Setting the desired value. The new value is shown on
the right-hand side of the symbol on home screen
cooling.
TIP
Wait 24 hours before making a new setting,
so that the room temperature has time to sta-
bilise.
If it is cold outdoors and the room temperature
is too low, increase the curve slope in menu
1.30.1 by one increment.
If it is cold outdoors and the room temperature
is too high, reduce the curve slope in menu
1.30.1 by one increment.
If it is warm outdoors and the room temperat-
ure is too low, increase the value in menu 1.1.1
by one increment.
If it is warm outdoors and the room temperat-
ure is too high, reduce the value in menu 1.1.1
by one increment.
MENU 1.3 - ROOM SENSOR SETTINGS
Factor system cooling
Setting range: 0,0 - 6,0
Activate room sensors to control the room temperature
here.
You can connect up to four room sensors to each cli-
mate system, and you can give each sensor a unique
name.
The sensor in each climate system that is furthest from
the set temperature takes control; the compatible
product tries to keep the temperature down in the room
whose sensor is furthest from the set value.
Caution
A slow heating system such as underfloor
heating may be inappropriate for controlling
with room sensors.
Factor system
You can also set a factor that determines by how much
the difference between the desired and current room
temperature will affect the supply temperature to the
climate system. A higher value gives a greater and faster
change in the cooling curve’s set offset.
Caution
Too high a set value for "factor system" can
result in an uneven room temperature.
