1. AC208EM2 (24VAC) control panel (digital thermostat).
The AAC208EM2 (24VAC) control panel (digital thermostat) provides:
• Switching the air handling unit ON/OFF.
• Selecting one of 3 speed modes.
• Display of room temperature.
• Scheduled
operation.
2. P3-1-300 speed switch.
The P3-1-300 rotary speed switch is used for switching one of three speeds and for switching
the unit on/off .
3. CO
2
sensor.
The CO
2
sensor with a no-contact is used in utility and public spaces and ensures high-speed
ventilation when the level of carbon dioxide is higher than the set maximum value.
Any CO
2
sensor commutating voltage of 24 V (0.1 A) can be used for connection to the unit.
WARNING: The CO
2
sensor must close a contact if the CO
2
level exceeds the set point and
open it when the CO
2
level falls below the set point.
4. Mechanical humidity sensor.
The mechanical humidity sensor with a no-contact is used for humidity level control in the room. If humidity exceeds the set point, the unit
switches from the regular operation mode to the high speed mode. The unit will operate in the high-speed ventilation mode until the relative
humidity falls below the set point. Adjust the level of humidity if necessary.
Any mechanical humidity sensor that can commutate 24 V (0,1 A)voltage is suitable for connection to the unit.
WARNING: The humidity sensor must close a contact if the humidity level exceeds the set point and open it when the humidity level
falls below the set point.
5. Mechanical timer
The remote mechanical timer must be installed in areas of air pollution. The timer is used for switching from regular operation mode to the high
speed ventilation mode. Up to 5 timers can be installed in a building within a distance to the unit of maximum 150 m.
Any mechanical timer commutating voltage of 24 V (0.1 A) can be used for connection to the unit.
6. ON/OFF switch.
The ON/OFF switch must be installed in areas of air pollution. When the contacts of the ON/OFF switch are closed the unit switches to a high
speed ventilation mode. Open the contacts of the ON/OFF switch to return to a continuous low-speed ventilation mode.
Any switch commutating voltage of 24 V (0.1 A) can be used for connection to the unit.
