Only the TROX Technical Service can change the fol-
lowing parameters:
Cascade
influence
- This parameter influences the calcula-
tion of the supply air setpoint tempera-
ture. The higher the cascade influ-
ence, the smaller the deviation of the
supply air temperature from the cas-
cade basic value; factory setting: 40 %
Allowed con-
trol deviation
- Range for which the supply air temper-
ature is not corrected; factory setting:
0.5 K
Gain - Follow-
up control
- The higher the 'Gain - Follow-up con-
trol' value, the larger the valve stroke
change; factory setting: 4.0
Time constant
- Follow-up
control
- The higher the 'Time constant -
Follow-up control' value, the more
often the valve stroke is adapted;
valve setting: 5.0
Fan stage (Fig. 19/5)
Temperature
deviation at max-
imum fan stage
- When the set T
set
to T
actual
devia-
tion is reached, the fan is automat-
ically set to the highest stage; fac-
tory setting: 3.0 K
Minimum resting
time at current
fan stage
- Period of time for which the current
fan stage remains set; factory set-
ting: 180 s.
3.2.2.1.2 Heating
Room temperature limits (Fig. 19/7)
In heating mode the room temperature is heated to the
comfort range lower limit for the operating mode. If the
room temperature is below the comfort range, the unit
starts to heat the room air. If the room temperature is
within the comfort range, the supply air is provided to
the room with the set cascade basic value for heating.
You can set the lower limit of the comfort range for
each operating mode independently.
Recommended:
–
Occupied: 21 °C
–
Standby: 21 °C
–
Unoccupied: 19 °C
Supply air temperature limits (Fig. 19/8)
For a comfortable room climate the supply air tempera-
ture should not exceed 45 °C.
You can set the upper limit of the comfort range for
each operating mode independently.
Recommended:
–
Occupied: 45 °C
–
Standby: 45 °C
–
Unoccupied: 45 °C
Control parameters (Fig. 19/9)
Cascade basic value
- Cascade control setpoint
value; factory setting:
22 °C
Cascade influence
- Factory setting: 40 %
Allowed control deviation
- Same as cooling
Gain - Follow-up control
- Same as cooling
Time constant - Follow-up
control
- Same as cooling
Only the TROX Technical Service can change grey
parameters.
Fan stage (Fig. 19/10)
Temperature
deviation at max-
imum fan stage
- When the set T
set
to T
actual

tion is reached, the fan is automat-
ically set to the highest stage; fac-
tory setting: 3.0 K
Minimum resting
time at current
fan stage
- Period of time for which the current
fan stage remains set; factory set-
ting: 180 s.
