V-08 Enables (yes)
This parameter enables/disables fan start-up after power supply failure. Disable function (no) disables the fan
start-up after the power supply failure and enable function (yes) enables the fan start-up after the power supply
failure;

Correct time
(Correct time)
0
Controller timer correction factor per month. If the controller timer is too fast or too low, adjust the timer
respectively by means of adjusting the miscoordination time per month. Set the coeffi
cient in seconds with
minus mark if the controller timer is too fast or plus mark if the controller timer is too slow.

2222
Use this function to edit the engineering password. To change the engineering password shown as **** select
the fi rst number with buttons and and press Enter, then enter the second number with buttons and ,
then press Enter and so on. To return to the previous digit entry press Esc. After the last number the controller is
entered the new password is saved. From now on access to the engineering menu required entering of the new
password. Note: In case of the controller adjustments reset (refer Eng. Adjust., reset) the engineering password
is set as 2222.

(Light)
Auto (Auto)
Controller light mode. In automation (Automat) mode the display light is off in set time period provided that no
buttons are pressed; in On mode the display light is permanently on.
Engineering Adjustment
(Eng. Adjust.)
Engineering menu contains engineering adjustments protected by the engineer password (factory setting
2222).
Electric heater adjustment
(Adjust-heater)
Electric heater adjustment menu.
E-01 1 Time required for heat removing from the electric heating element after the unit is off [min].
Е-02 600
Time required to determine too low supply air temperature [sec]. If during the fan operation the supply air
temperature remains below the E-03 parameter after completion of the E-02 period, both fans are stopped and
the alarm signal U6 is generated (refer Alarms, U6 Alarm).
Е-03 10
Critical temperature point for supply air temperature [°C]. If the actual supply air temperature after the air heater
remains below this parameter within the time period E-02, the fans are stopped and the alarm signal U6 is generated.
Е-04 6 Electric heater power control time [s].
Е-05 1 Minimum time required to turn the electric heater on/off [s].
Е-08 2
Parameter adjustment for the supply air temperature regulation by the electric heater - PI-regulation factor of
proportionality.
Е-09 60
Parameter adjustment for the supply air temperature regulation by the electric heater - PI-regulation integrating
factor [s].
Е-10 0,5
Parameter adjustment for the supply air temperature regulation by the electric heater - dead zone [°C]. If the
discrepancy is below E-10, it shall be disregarded.
Heat exchanger adjustment
(Adjust-Recuper.)
Confi guration menu for the heat exchanger protection.
R-03 30 Heat exchanger start-up time [s].
R-04 2 Parameter adjustment for the heat exchanger control - PI-regulation proportion factor.
R-05 60 Parameter adjustment for the heat exchanger control parameter - PI-regulation factor of proportionality [s].
R-06 0,5
Parameter adjustment for the heat exchanger control - dead zone [°C]. If the discrepancy is below R-06, it shall
be disregarded.
Start-up control Confi guration menu for the fan start-up.
Restart Disable
This parameter enables/disables fan start-up after power supply failure.
Disable function (no) disables the fan start-up after the power supply failure and enable function (yes) enables
the fan start-up after the power supply failure.
