10. CONTROL SYSTEM
Control equipment customized according to every special customer need. All AmberAir units ordered with control system are factory configured
and tested together with all the necessary field components.
Control system types:
• Built in control system. All components are in control section.
• Built in outside control system. Control cabinet mounted on the unit’s doors or mounted on particular distance from the unit.
• Not built in control system.
NOTE: For built in outside control systems all cables (between control box and air handling unit) must be protected from direct UV, rain and me-
chanical influence.
Control system comes with:
• Electric part project;
• Main switch (for on/off main power supply);
• Control box ventilation fan (if needed);
• Control box heater (if needed);
• Protection components (circuit breakers, fuses);
• Control components (frequency inverters (if needed), contactors and relays(if needed));
• Additional components (modular socket);
• Controller;
• Terminals for cable connection;
• Cable glands;
• Sensors for air temperature and air quality control (if needed);
Safety notes:
Control system maintenance, control and troubleshooting must be carried out by trained personnel. Any legal regulations or regulations issued by
authorities must be observed during assembly and operation.

Connecting main power supply cable to the control system:
Make sure main power supply is the same as the control system power supply (voltage, frequency).
Connecting different type of power supply can damage control system or AHU components.
Control system power supply is indicated in the electric part project or on the sticker inside control system.
Connect main power supply cable to the terminals or main power switch.
