Parameters / Function description
Parameter description The specialist parameters listed in the table in the last section
are described in detail below.
The column on the left shows the designation of each
parameter and its number.
Not all parameters listed in the table will be present in every
system conguration.
Hysteresis OFF
LM013
Factory setting: 1 K
Range: 0 - 3 K
The heating control by temperature stops if the currently
actual room temperature or extract air temperature exceeds
the set temperature by the Hysteresis OFF value.
Minimum fan speed
LM015
Factory setting: 30 %
Range: 5 - 60 %
Min. speed "n-min" (minimum output voltage)
Setting (if required) of a minimum output voltage, i.e. a base
speed (minimum air change) for the connected fans which
must be maintained during temperature control and CO2
control.
Never set below 30 %!
Maximum fan speed
LM016
Factory setting: 70 %
Range: 25 - 100 %
Max. speed "n-max" (maximum output voltage)
Setting (if required) of a maximum output voltage, i.e. a speed
limit (to prevent excessive air noise) for the connected fans
which must not be exceeded during temperature control and
CO
2
control.
P component
for speed control
LM017
Factory setting: 10
Range: 1 - 20
The P component for speed control determines how sharply
the output signal of the Analogue output is modied in
proportion to a control deviation. (0-100 %)
If the P component is set low, the control unit responds more
quickly.
If the P component is set high, the control unit responds more
slowly.
Ratio of extract air/
supply air fan speed
LM018
Factory setting: 93
Range: 50 - 150
In order to run air handling systems so that positive or
negative pressure is created in the room, the speeds of the
supply air and extract air fans must be set differently.
Setting LM018 at 100 → parallel operation
LM018 at > 100 → negative pressure
LM018 at < 100 → positive pressure
Weather-compensated
summer shutdown
LM020
Factory setting: OFF
Range: ON/OFF
By enabling this parameter, the system can be switched on
and off according to the outside temperature.
The system must be connected to an outside temperature
sensor for this function to be available (see "Additional
functions"). In the control panel, disconnect the internal wires
across terminals X2 21/22 and connect the external outside
temperature sensor.
Enable this parameter only if you are replacing an
internal temperature sensor with an outside temperature
sensor one.
Page 29
3063527_201308

Differential for heating
LM021
Factory setting: 1
Range: 1 - 10 K
This parameter denes the outside temperature, relative to
the set room temperature, at which the ventilation unit stops.
Example:
Set room temperature 20 °C, parameter LM021 set to 5.
If the outside temperature is > 25 °C the ventilation unit
will be switched off. At 1 kelvin below that, the unit will be
enabled again.
Room frost protection
LM023
Factory setting: ON
Range: ON/OFF
Activating this parameter allows the system to be switched
on when the room temperature falls below the room frost
protection limit.
Room frost protection
temperature
LM024
Factory setting: 5
Range: 0 - 30 °C
If the room temperature falls below the set value, the reheater
and the fan are activated. Once the temperature rises 2 K
above the set temperature, the system stops again.
The fan speed can be preselected manually.
Fan speed for
Econ.operation
LM060
Factory setting: 70 %
Range: 40 - 100 %
When Economy operation is active, the fan is operated at the
speed preselected here. The set speed applies to backup
mode, night ventilation, summer mode and peak ventilation.
P component for
heating circuit mixer
LM080
Factory setting: 12
Range: 5 - 20
The P component for the heating circuit mixer (HR)
determines how sharply the output signal of the heating
circuit mixer is modied in proportion to a control deviation.
If the P component is set low, the control unit responds more
quickly.
If the P component is set high, the control unit responds more
slowly.
Integral action time for
heating circuit mixer
LM081
Factory setting: 2 min.
Range: 0 - 25 min.
The integral action time for the heating circuit mixer (HR)
determines how great the time effect is on the output signal of
the heating circuit mixer due to a control deviation.
If the integral action time is set low (high time effect), short
correction times result. However, so do greater uctuations
around the set value. If the integral action time is set high,
longer correction times result. This also means lesser
uctuations around the set value.
Cascade effect
LM100
Factory setting: 2
Range: 0 - 20
The cascade effect determines how sharply the set
temperature for supply air is modied in proportion to a
control deviation in the room temperature.
If the P component is set low (low gain), longer correction
times result, whilst uctuations around the set value will be
minor. If the P component is set high, shorter correction times
result. However, so do greater uctuations around the set
value.
Parameters / Function description
Page 30
3063527_20130830
Integral action time for
cascade
LM101
Factory setting: 2 min.
Range: 0 - 25 min.
The cascade integral action time determines how great the
time effect is on the set temperature for supply air due to a
control deviation in the room temperature.
If the integral action time is set low (high time effect), shorter
correction times result. However, this also means greater
uctuations around the set value. If the integral action time
is set high, longer correction times result. This also means
lesser uctuations around the set value.
Supply air maximum limit
LM102
Factory setting: 50 °C
Range: 20 - 60 °C
The supply air maximum limit determines the maximum
temperature at which supply air can be blown into the room.
If the differential in temperature between the set temperature
and the actual temperature is high, control based on room
temperature could lead to very warm air being conveyed into
the room. This high supply air temperature would cause the
air quality in the room to worsen. To prevent that, the supply
air temperature is limited to a maximum value in the case of
heating.
Temperature - control
type
LM103
Factory setting:
Supply air temperature control
This parameter sets the type of temperature control.
- Auto
- Supply air temperature control
- Extract air:supply air cascade
For a detailed description of the control functions, see BML.
Damper lead time
LM114
Factory setting: 0 s
Range: 0 - 150 s
To prevent whistling noises occurring on the dampers when
the fan is switched on, the outside air dampers are opened
rst, with the fans being switched on after this time (60 s) has
elapsed.
Night ventilation limit
LM130
Factory setting: 22 °C
Range: 10 - 30 °C
If night ventilation is activated (DEFAULT SETTING), this
parameter is used to determine the room temperature or
extract air temperature at which night ventilation starts or
stops (±1 K).
Night ventilation starts if the room or extract air temperature is
higher than the set value ± 1 K.
Night ventilation stops if the room or extract air temperature is
lower than the set value.
Night ventilation
start condition
LM131
Factory setting: 5 K
Range: 2 - 20 K
If night ventilation is activated (DEFAULT SETTING), this
parameter sets the outside temperature, relative to room
temperature, at which night ventilation starts.
Night ventilation starts when the outside temperature is lower
than the room temperature minus the "Night ventilation start
condition" parameter.
Parameters / Function description
Page 31
3063527_201308
31
Night ventilation,
minimum outside
temperature
LM132
Factory setting: 12 °C
Range: 5 - 20 °C
The "Night ventilation minimum outside temperature"
parameter sets the minimum outside temperature below
which night ventilation is disabled.
P component for HR
LM150
Factory setting: 12
Range: 5 - 20
The P component for HR determines how sharply the output
signal of the HR damper is modied in proportion to a control
deviation.
If the P component is set low, the control unit responds more
quickly.
If the P component is set high, the control unit responds more
slowly.
Integral action time for
HR
LM151
Factory setting: 2 min
Range: 0 - 25 min
The integral action time for HR determines how great the
time effect is on the output signal of the HR damper due to a
control deviation.
If the integral action time is set low (high time effect), shorter
correction times result. However, this also means greater
uctuations around the set value. If the integral action time
is set high, longer correction times result This also means
lesser uctuations around the set value.
Air quality control / CO2
LM160
Factory setting: ON
Options: OFF - ON
If the system is equipped with an air quality sensor / CO2
sensor, this parameter must be set to ON in order to make
this function available.
Air quality / CO2

LM201
Factory setting: 1 week
Range:1 -10 weeks
Subject to setting, the process is as follows:
After the motor starts, lters are checked after the test interval
has elapsed. Fan runs at 100 % speed, and after a delay of 60 s
a fault message is issued on the BML programming module if
lters are dirty. The system resumes its control mode and the
fan speed is reset again. If the system continues running day
and night, a lter check will be carried out after the test interval
has elapsed plus 24 hours.
Filter service message
LM202
Factory setting: OFF

Standard functions The standard functions of the controller are described below.
Motor protection The motor winding temperature is monitored with the aid of
thermistors set into the motor windings or PTC thermistor
pellets.
If the winding temperature rises above the dened value, the
motor and all outputs are switched off. A fault message is
displayed on the programming module. The motor will only
restart once the fault is removed (motor cooled down) and the
fault message is reset.
The fault is reset by acknowledging the fault on the BML
programming module.
Relevant parameters: none
Room frost protection

rises 1 K above the backup temperature, everything stops
again.
Relevant parameters:
Program selector, time program, in OFF mode, backup
temperature, night mode
Supply air minimum limit
for heating
If the supply air temperature (temperature of air blown in)
falls below the set minimum limit value, the heating mixer is
activated (100 %) (HR and reheater coil).
The heating modules are not switched off again until the
temperature has risen above the set value.
In addition, if the supply air temperature falls below the
minimum limit, the current fan speed is set to the minimum
speed (parameter LM 015) after 900 s have elapsed. If the
supply air minimum limit then ceases to be active, the fan
speed is returned to its nominal speed.
If the supply air minimum limit is still active after 5 minutes
despite the speed reduction, a fault message is issued (and
the system shuts down).
This will be reset automatically once 5 hours have elapsed or
when the fault is acknowledged on the BML.
Filter contamination
fault trigger
Parameters LM202 and LM203 can be used to activate a lter
fault by means of the number of hours of fan operation.
Active lter monitor A differential pressure cell can be used to trigger a fault
message when the lter is dirty; see parameter LM200.
Fan run-on time To prevent re-heating by the electric heater coil, the fan stops
only after a run-on time of 45 seconds after system shutdown.
External ON/OFF An on-site contact can be used to switch the system on and
off within the time program.
Contact closed:
System runs according to the time program
Contact open:
System switched off by time program
If the system is always going to be operated via the external
switch, the time program must be enabled 24 hours a day
The additional functions of the controller are described below.

Additional functions
Room/supply air
cascade control
With room/supply air cascade control, the set supply air
temperature is corrected according to the control deviation of the
room temperature.
Relevant parameters:
Cascade effect LM100, integral action time for cascade LM101,
supply air minimum limit (default setting), supply air minimum limit
LM102
Pre-requisites:
Room sensor (extract air sensor) and supply air sensor
The set supply air temperature is dependent on the load
conditions in the room. The actuating variable from the room
temperature control is transferred as set value to the supply air
temperature control. This results in the set supply air temperature
being varied according to the deviation in room temperature.
Night ventilation In summer, night ventilation pre-cools the room for the
following day with cool outdoor air.
Relevant parameters:
Night ventilation limit LM130; start condition Tr > Ta LM131;
permissible outside temperature LM132
Pre-requisites:
- Room sensor (extract air sensor) and outside temperature
sensor are installed
- Time program set to "OFF"
- Outside temperature > minimum outside temperature
(LM132)
- Outside temperature < room temperature + delta (LM131)
- Room temperature > set room temperature (LM130)
- Works only when backup mode is selected
- Enabled from 1 March to 31 October
- Enabled from 20:00 to 07:00 h
Effects:
- Fans are switched on
- Speed according to parameter LM060
- HR heater coil is switched off
- Outside air dampers are opened
- Set temperatures for switching night ventilation on and off
are dened by parameter LM130.
When night ventilation is activated, sensor values are
checked for the rst 7 minutes.
(Fan speed according to parameter LM 060; checking
outdoor air, extract air/room air temperatures.)
If the conditions dened by parameters LM 130 - LM 132 are
met, night ventilation continues. If the conditions are not met,
night ventilation stops again.
If, during the time in which night ventilation is enabled, a
shutdown occurs (temperature below threshold in parameter
LM 130), another sensor check is activated after 125 minutes
and runs for 7 minutes.
In order to use night ventilation efciently, the outside
temperature sensor in the appliance should be disabled and
shifted outside.

3063527_20130836
Additional functions
Preheater coil for HR
Ice guard,
Filter drying
When the outside temperature is below 0 °C, the preheater
coil is activated.
Once the temperature rises to the set temperature +
hysteresis, the preheater coil is switched off again.
Condensate overow When a condensate pump is connected, the amount of
condensate is monitored. If the limit is exceeded, the
ventilation unit stops and a fault message is issued on the
BML (active only with cooling congurations).
Summer shutdown With parameters LM020 / LM021, ventilation can be
switched off automatically in the event of very high outside
temperatures to prevent the interior getting too hot.
When summer shutdown is activated, the outside
temperature sensor in the appliance must be disabled and an
external outside temperature sensor used.
Heat recovery In many industrial plants, waste heat from cooling circuits/
lighting is available. Heat recovery allows the utilisation of
this free heat source for heating purposes. With a crossow
heat exchanger, energy costs can be drastically reduced in
this way.
Heat recovery is actuated by an Analogue control signal
(0-10 V). Heat recovery is applied for heating and cooling
purposes by capturing and comparing the room (extract air)
temperature, the outside temperature and the supply air
temperature.
HR actuation takes priority over the actuating signal for
heating. The reheater coil is not activated unless and until
the HR control signal is at 10 V and the set temperature has
still not been reached.
Relevant parameters:
P band for HR LM150, integral action time for HR LM151
The parameters are switched to active only in accordance
with the conguration
Function is only supported in conjunction with an outside
temperature sensor/room sensor or extract air sensor.
HR ice guard To prevent frost forming on the extract air side of the HR
system, the extract air temperature is captured by an ice
guard sensor and if the temperature falls below +6 °C, the HR
system is steadily closed. At 1 °C the HR system is closed
completely. The heating valve continues to be controlled
towards its set value independently. If the temperature stays
below the icing-up temperature for more than 2 minutes, a
fault message is issued. The fault message automatically
extinguishes when the temperature rises above the limit
temperature. Ice guard function does not become active until
the fan has been running for at least 5 minutes.

Fault messages are issued to the programming unit with plain
text, info no. and a symbol
The display shows:
(e.g. "Fault zone, 207 - motor protection")
Troubleshooting:
1. Check whether the motor protection on the supply/extract
air fan has responded. Do so by measuring across the NC/
COM terminals whether the contact has closed (using an
ohmmeter or continuity tester).
If the contact is closed, the motor protection has responded.
After remedying the fault, press "Acknowledge faults"
on the BML. The system will resume operation.
