"Airflow" is displayed: (EF = Extract
SF = Supply)
Note! Airflow is given in l/s. On "Norm", within the area -20 to +20 %, you
can choose different airflows for supply and extract. Standard
setting is 0%,. Positive difference means higher extract airflow. On
"Max" and "Min" it is only possible to choose airflow for extract fan.
Chosen difference on "Norm" will automatically be maintained on
"Max" and "Min".

Analog inputs
The unit is fitted with various temperature sensors. Choose "Analog input"
to read the actual temperatures.
NO
Turn
to "Analog input". Confirm
NO
SS = Supply air temperature for constant supply air temperature.
Measured after the heater battery inside the unit.
If water coil is installed, the sensor must physically be moved into
NB!
the duct and be installed after the water coil.
ETS = Temperature sensor in extract air. Used to de-activate the need
for cooling recovery, which is a part of the rotor guard function.
EHS = Temperature sensor in the exhaust air. Used together with ETS to
give notice of unforeseen rotor stop.
OH =
Overheat sensor. Will dis-connect the heater at measured
temperature exceeding 55
temperature.
If water coil is installed, the sensor must physically be moved to
