2. SYSTEM START-UP
!
Operation of the AHU is strictly arrested by the fire-protection alarm, activation of the
thermal protection of fans' motors, threefold activation of the protection of electric heater
and threefold activation of the anti-frost thermostat. Each of these events requires removing
the cause of the alarm and then canceling it ((see more details in Advanced Manual).

Switching on power supply of the control gear with the mains switch (Q1M). Correct power supply and
good BIOS operation is indicated by yellow and green LED lamps on the controller's PCB.
The system is ready for operation after about half minute from switching on.
