2.6.3.g Eco mode
If this function is activated, the motor outputs are
de-energised 3 minutes after receipt of the last
ventilation command.
2.6.3.h Time until next thermostat query
If a connected thermostat is overridden by a
manual command (e.g. by desired intermittent
ventilation through a connected ventilation but-
ton), it must be determined how long the control system must
wait before sending a new query to the thermostats. This
waiting time can be set from 10 seconds to 12 hours in
1 second steps.
To be able to use this function, at least one button under the
ventilation sources must be assigned “T” for thermostat.
2.6.3.i Ventilation ONLY with analog input (optional) —
Dependency logic
With this function, the analog input is used with
the aid of an external analog circuit as an addi-
tional condition for the execution of a ventilation
function (dependency logic). For this purpose, the analog
input (terminal "+") is permanently checked for a continuous
signal (min. 0.8 mA). As long as the signal is present, a ven-
tilation function can be performed. If this is not the case, none
of the connected actuators is electrically controlled
2.6.4 Analog input (optional)
This input allows a gap or partial ventilation to be
controlled. For example, this control signal can
come from a building control system.
For this purpose, the total opening and closing times must be
measured and then entered on site. The connected actuators
then move to the required position, proportional to the applied
supply voltage or current. To ensure that this opening
mechanism works properly, the actuators
must be closed
completely at least once daily.

ATTENTION
The continuous signal is only detected from 0.8 mA. The
maximum current at the input must not be exceeded! This
input is deactivated by default.
ATTENTION
Before connecting, the type of the input signal (current /
voltage) must be determined via SIMON LINK. The analog
input is deactivated by default.
