D700e Standard regulation for electrically
heated units
• This regulator controls the various
ventilation and heating stages of the
connected air curtain directly.
• If the unit is switched off, fan stage 1
is switched on by pushing button “FAN
SELECT”. By pushing this button again the
next higher fan stage is switched on.
• After reaching fan stage 3 the fan stages are
switched back down by pushing this button
again. When fan stage 1 is reached and the
button is pushed again the unit is switched
off. The set fan stage is indicated by an LED.
When the unit is switched off the LED "OFF"
is lit.
• After setting a ventilation stage, it is possible
to set a heating stage by pushing button
“HEATING SELECT”. Here, to the next higher
heating stage is set by pushing this button
again. It is not possible to set a heating stage
which is higher than the set ventilation stage.
• If, for example, when heating stage 3 and
ventilation stage 3 are set, the ventilation
stage is switched back from 3 to 2, the heating
stage is automatically also switched from
stage 3 to stage 2. The set heating stage is
indicated by an LED. The LED "OFF" is lit
when no heating stage is set.
• Should there be a signal from the follow-
up thermostat after switching off the unit,
the fans are switched on again until the unit
is cooled down. This follow-up function is
indicated by blinking of LED fan stage 3.

Manual control
The controller has 2 buttons for up and down
respectively, for setting the steps 0-1-2-3-4-5,
controlling the air volume. The set step is
shown with LED-lights.
If a solenoid valve or thermo-electrical
actuator is connected to the internal PC-
board of the air curtain the third button can
control the summer/winter (off/on) switching
of the heating medium supply. If the fans are
shut off by selecting step 0 / OFF the heating
medium supply is automatically closed. It is
opened again when the unit is started again.
The same buttons can be found on the IR-
remote controller IR01 (accessory on some
markets).
Automatic control
The controller is equipped with a terminal for
a potential free contact through which the air
curtain can be automatically controlled, i.e.
with a door contact, a room thermostat or a
BMS system.
When the unit is to run, when the door is
open or when either a room thermostat or
BMS is giving a start signal, the potential free
contact should be open and the required fan
step can be set on the controller.
The controller can be adjusted through a DIP-
switch inside the controller whether to shut
off completely or to run on lowest speed when
the potential free contact closes.
Switch in position On: Air curtain switches
on/off.
Switch in position Off: Air curtains switches
between low/high speed.
To avoid frequent switching of the fan speed
an overrun time between 15 and 75 s can be
set on the controller.
