If the control panel in “Intensive windshield heating” mode
receives a signal to switch on a conditioner, then the conditioner
will be switched on and the system will perform the drying of the
climate control unit.
“AUTO” mode turns on by switch 3 (Fig. 3.21 c) in position
“ ”.
In this mode the unit controls the air damper, so that the tem-
perature set by rotary switch 1 (Fig. 3.21 c) is maintained auto-
matically. It is possible to manually set the required air current
distribution (by mode buttons 8, 9, 10).
“AUTO” mode turns off after switch 3 is shifted from position
“ ” to any other position, or after “Intensive windshield heating”
mode is ON.
In cold weather (AUTO mode, ambient temperature is: lower
than 15 °С), the system first automatically selects constant low
speed and the flap position of the windshield air cooling, until the
heater starts supplying warm air to avoid discomfort caused by
cold air.
In hot weather (AUTO mode, ambient temperature is: higher
than 30 °С), the system first automatically selects constant low
speed and the flap position of the windshield air cooling within
5 s, and then it returns to the normal control to avoid discomfort
caused by hot air.
“Interior preh mode.
The control panel goes to “Interior preheating” mode if the
source of power is the liquid heater.
When this mode is turned on (the ignition is turned off), the
control board indicates this mode with orange blinking illumina-
tion on rotary switch 2 with a 4.5 s blinking period (1.5 s turned
on/3 s turned off).
If the position of rotary switch 3 exceeds position 4 of the
switch, then the control panel limits the maximum rotation speed
of the fan and rotary switch 3 goes to the 4th position in order to
prevent forced accumulator battery discharge.
