max solar pool temperature: Here, you can set the maximum
temperature at which the solar panel stops pool heating (if
the installation is structured in this way). Pool heating can
only occur if there is a heat surplus once the heating and/or
hot water demand is met.
If the unit has an anti-freeze function and/or solar panel
cooling you can activate them here. When the function has
been activated, you can make settings for them.
freeze protection
anti-freeze temperature: Here, you can set the temperature
in the solar panel at which the circulation pump is to start
to prevent freezing.
solar panel cooling
start solar collector cooling: If the temperature in the solar
panel is higher than this setting, at the same time as the
temperature in the solar tank is higher than the set maximum
temperature, the external function for cooling is activated.
See the accessory installation instructions for function de-
scription.
MENU 5.3.7 - EXTERNAL ADDITION
Make settings for external addition here. External addition
is for example external oil, gas or electric boiler.
If the external addition is not step controlled, in addition to
selecting when this should start also set the run time for
the addition.
If the external addition is step controlled you can select
when the addition is to start, set the maximum number of
permitted steps and whether binary stepping is to be used.
If you select "prioritised additional heat" the heat is used
from the external addition instead of the heat pump.
See the accessory installation instructions for function de-
scription.
MENU 5.3.11 - MODBUS
address
Factory setting: address 1
word swap
Factory setting: not activated
As from Modbus 40 version 10, the address can be set
between 1 - 247. Earlier versions have a fixed address (ad-
dress 1).
Here, you can select if you want to have "word swap" instead
of the preset standard "big endian".
See the accessory installation instructions for function de-
scription.

Setting range: ERS S10, ERS 20/ERS 30
Factory setting: ERS 20 / ERS 30
action level monitor
Setting range: off, blocked, level monitor
Default value: level monitor
months btwn filter alarms: Set how often the filter alarm is
to be displayed.
lowest extract air temp.: Set the minimum extract air tem-
perature to prevent the build-up of ice on the heat ex-
changer. The supply air fan speed reduces, if the extract air
temperature (BT21) is lower than the set value.
bypass at excess temperature: If a room sensor is installed,
you set the over-temperature at which the bypass damper
(QN37) will open here.
bypass during heating: Activate whether the bypass damper
(QN37) will also be allowed to open during heat production.
cut-out val. exh. air temp.: If no room sensor is installed, you
set the exhaust air temperature at which the bypass damper
(QN37) will open here.
product: Here, you set which ERS model is installed.
action level monitor: If "level monitor" is selected, the
product issues an alert and the fans stop when the input
closes. If "blocked" is selected, text in operating info shows
that the input is closed. The fans stop until the input is open.
