Menu 1.9.2 - external adjustment
Menu 1.9.3 - min. flow line temp.
Menu 1.9.4 - room sensor settings
Connecting an external contact, for example, a room
thermostat or a timer allows you to temporarily or pe-
riodically raise or lower the room temperature while
heating. When the contact is on, the heating curve off-
set is changed by the number of steps selected in the
menu. If a room sensor is installed and activated the
desired room temperature (°C) is set. If there is more
than one climate system the setting can be made sep-
arately for each system. More information after se-
lecting "?".
Here you can turn on room sensors that regulate the
room temperature.
Here you can set a factor (a numerical value) that deter-
mines how much an over or sub normal temperature
(the difference between the desired and actual room
temperature) in the room is to affect the supply tem-
perature to the climate system. A higher value gives
a greater and faster change of the heating curve's set
offset. More information after selecting "?".
In menu 1.9.3 you select heating or cooling (if active),
in the next menu (min. supply temp.heating/cooling)
set the minimum temperature on the supply tem-
perature to the climate system. This means that HM
6Split / HM 12Split never calculates a temperature
lower than that set here.
If there is more than one climate system the setting
can be made separately for each system.
ADVICE
Wait 24 hours before making a new setting, so that
the room temperature has time to stabilise.
If it is cold outdoors and the room temperature is too
low, increase the curve slope by one increment.
If it is cold outdoors and the room temperature is too
high, lower the curve slope by one increment.
If it is warm outdoors and the room temperature is too
low, increase the curve offset by one increment.
If it is warm outdoors and the room temperature is too
high, lower the curve offset by one increment.
ADVICE
The value can be increased if you have, for example, a
cellar that you always want to heat, even in summer.
You may also need to increase the value in "stop heat-
ing" menu 4.9.2 "auto mode setting".
Factory setting:
heating
climate system 1: 0
cooling (if activated)
climate system 1: 0
Factory setting:
heating
climate system 1: 20
cooling (if activated)
climate system 1: 18
Factory setting:
inactive
IMPORTANT
Too high a set value for "factor system" can (depending
on your climate system) produce an unstable room tem-
perature.
CAUTION
A slow heat-releasing heating system, such as for
example, underfloor heating, may not be suitable for
control using the heat pump's room sensor.
IMPORTANT
With active cooling, the minimum temperature should
be set based on the temperature of the heating system.
