If the temperature at collector sensor S1 exceeds the adjusted starting temperature
(factory setting 10 °C), the inlet air fan (V1) switches on.The disk valve opens.The
basement is vented, dehumidified and heated.The outlet air fan (V2) removes the air
to the outside and ensures a constant air flow.
The internal combined sensor limits the room temperature to a maximum of 25 °C
(inlet air fan V1 switches off) and monitors the relative humidity in the basement.
A time-dependent ventilation (interval operation) at night takes place by means of
the timer function.
The dew point lock enables the operation of the fans, if the dew point outside (K2)
is lower than the dew point inside (K3/ internal combined sensor).This prevents the
condensation of warm outside air on cool basement walls (example: thunderstorm
tendency during midsummer).

the adjusted value (ΔTon), the inlet air fan (V1) switches on.
The garage is vented, dehumidified and heated.The used outlet air escapes via leaks
in the garage or via special ventilation devices such as ventilation grids in the garage
walls.The internal combined sensor (K3) limits the room temperature in the garage
to a maximum of 30 °C (inlet air fanV1 switches off).
If the humidity in the garage increases significantly (e.g. by a wet parked car), the
humidity control (combined sensor 3) enforces a ventilation in order to dehumidify
the garage. The timer is used for the time-dependent ventilation of the garage, if
required.
Note
A humidity measurement with the external combined sensor 1 improves
the accuracy.The allocation of the combined sensor is then at K1 instead
of K3.

6 Functions
The controller has functions with different priorities.The functions are described in
detail in the following and have the following priorities:
Maximum collector temperature/antifreeze = priority 1
Dew point lock = priority 2
Relative humidity = priority 3
Cooling = priority 4
Timer = priority 5
Temperature = priority 6
1 = highest priority , 6 = lowest priority
6.1 Operating mode
Auto:Automatic operation according to the activated functions and priorities.
Off:Only emergency functions are active (maximum collector temperature,antifreeze).
Humidity: Operation according to the adjustments in the Humidity menu (see
page 22).
Cooling: Operation according to the adjustments in the Cooling menu (see page 22).
Timer: Operation according to the adjustments in the Timer menu (see page 20).
Temperature: Operation according to the adjustments in the Temperature menu
(see page 19).
If an operating mode has been selected, a security enquiry appears.
ÎIn order to save the selected operating mode, confirm the security enquiry
with Ye s .
The selected operating mode is displayed in the headline of the status menu.
Note:
Only the Auto mode has access to all adjusted functions of the controller.
Only change the operating mode, if the controller functions are to be
limited to the selected operating mode.
6.2 Temperature
In the Temperature menu, different temperature functions can be activated and
adjusted.
Starting temperature
The Starting temperature is used for defining a minimum collector temperature
which has to be exceeded for the fan to switch on. Sensor S1 is used as the refer-
ence sensor.The hysteresis is adjustable.
Temperature difference
The controller calculates the temperature difference between the collector sensor S1
and a selectable room sensor. If the temperature difference reaches or exceeds the
switch-on temperature difference, the fan switches on. If the temperature difference
reaches or falls below the adjusted switch-off temperature difference, the fan switches
off.
Note:
A room sensor is required for this function.
Room temperature
If the room temperature reaches or exceeds the adjusted maximum value, the fan
switches off.The hysteresis is adjustable.The Relay option can be used for activat-
ing the potential-free relay. If the room temperature reaches the adjusted maximum
value, the relay switches on.
Lock time
The lock time is used for adjusting a time frame in which the temperature functions
are locked.
Room sensor
The parameter Sen.Room is used for selecting a reference relay for the Tdifference
and Room temperature functions.
Note:
Only if at least one of the two functions is activated, will the parameter
be shown.

6.3 Timer
In the Timer menu, a day selection can be activated and adjusted or intervals for
the ventilation can be defined.
The parameter Output can be used for allocating an output to the timer. The
parameter Fan can be used for adjusting the fan speed for the timer operation.
The Day selection option can be used for selecting
and adjusting the timer with time frames.
In the Day selection channel, the days of the week
are available.
If several days are selected, they will be merged into
one combination for the following steps.
The last menu item after the list of days is Continue.
If Continue is selected, the Edit timer menu opens, in
which the time frames can be adjusted.
Fan
The parameter Fan is used for adjusting the fan speed for the temperature functions.
Maximum temperature
The parameter TMax is used for adjusting a maximum collector temperature. If
the collector temperature reaches or exceeds the adjusted maximum value, the fan
is locked.This function is always active, even if no temperature function is activated.
Antifreeze
The antifreeze function prevents too cold air from getting into the room. If the
collector temperature falls below the adjusted antifreeze temperature, the fan is
locked.This function is always active, even if no temperature function is activated.
