Action external blocking
Setting range: Level monitor/Blocked/Off
Lowest extract air temp. : Set the lowest extract air
temperature to prevent the build-up of ice on the heat
exchanger.
Action external blocking : ERS S10 has no built-in level
monitor, although it is possible to connect an external
one via AUX; the fans stop when the AUX input is
closed. When "level monitor" is selected, the product
issues an alert when the input closes; when "blocking"
is selected, text is displayed instead in operating info.
MENU 1.2.1 - FAN SPEED
Alternatives: normal and speed 1 – speed 4
The ventilation in the accommodation can be temporarily
increased or reduced here.
When you have selected a new speed a clock starts a
count down. When the time has counted down the
ventilation speed returns to the normal setting.
If necessary, the different return times can be changed
in menu 1.2.5.
The fan speed is shown in brackets (in percent) after
each speed alternative.

Night cooling during heating
Setting range: on/off
Here, you can activate night cooling. When the temper-
ature in the building is high, and the outdoor temperature
is low, a cooling effect can be obtained by forcing the
ventilation. When night cooling is activated, the fans run
at speed 4. For activated night cooling, the bypass
damper (QN37) is open.
Start temp exhaust air: Here, you set the exhaust air
temperature at which night cooling will start.
Min. diff. ind. temp. - outd. temp.: If the temperature
difference is greater than the set value for "Min. diff.
ind. temp. - outd. temp.", and the exhaust air temperat-
ure is higher than the set value for "Start temp exhaust
air", the ventilation operates at speed 4 until one of these
conditions is no longer valid.
