Function
Explanation
Exh. air red. vol.
corr.
You can use this function to set the
exhaust air volume flow for the reduced
ventilation in the case of deviations
between the target and actual value.
Sup. air red. vol.
corr.
You can use this function to set the
supply air volume flow for the reduced
ventilation in the case of deviations
between the target and actual value.
Diff.temp. bypass
You can use this function to set the tem-
perature amplitude between outside air
and exhaust air from which the bypass
switches from "open" to "half-open".
This means that, at a high sensitivity to
draughts, the value should be reduced.
When using a complete, passive cooling
capacity, the value should be increased.
Min. CO2 content
You can use this function to set the
CO
2
value (measured by the air-qual-
ity sensors) from which the product in-
creases the air volume flow in automatic
mode.
Max. CO2 content
You can use this function to set the
CO
2
value (measured by the air-qual-
ity sensors) from which the product
achieves the set nominal flow in auto-
matic mode.
Min. air humidity
You can use this function to set the re-
lative air humidity (measured by the
moisture sensor) from which the product
increases the air volume flow in auto-
matic mode.
Max. air humidity
You can use this function to set the re-
lative air humidity (measured by the
moisture sensor) from which the product
achieves the set nominal flow in auto-
matic mode.
System efficiency
You can use this function to monitor the
system efficiency after
P.03
has previ-
ously been run once. If there is an exten-
ded period of inefficiency, maintenance
message
M.802
is shown in the display.
Appliance type
You can use this function to set whether
you are installing/have installed a wall
unit or a ceiling unit.
Adjustment options:
–
1 = Small wall unit (air volume flow
260 m
³
/h)
–
2 = Large wall unit (air volume flow
360 m
³
/h)
–
3 = Ceiling unit (air volume flow
150 m
³
/h, L variant)
–
4 = Ceiling unit (air volume flow
150 m
³
/h, R variant)

the degree of system efficiency is shown in the
display.
1 / 2
Test result:
Efficiency: High
Test result:
Efficiency: Medium
Test result:
Efficiency: Low
If the
Efficiency: Low
test result is shown in the display,
first try to increase the system efficiency. (

▶
Inform the operator about how to handle the system. An-
swer any questions the operator may have. In particular,
draw attention to the safety information which the oper-
ator must follow.
