The regulation of the CO
2
control is carried out in the CO
2
controller, this being a percentage value of the reading range of the sensor in
relation to the desired carbon dioxide concentration (ppm).
For proper regulation you must follow the following steps:
Limit the operating range of the fan (JP1, SW2, R28, R29)
Regular SW1 (desired setpoint according to image). Being in this place imposed the value of the intended regulation.

ACCESSORIES - WATER COIL
The heating water coil module uses the hot water flow for heating the airflow. For proper operation and to avoid damaging the coil, the
following warnings must be observed:
• The coil should only be used for heating.
• Check the limits of the water temperatures and the pressure of the water.
• All hydraulic connections must be made in accordance with good practice in the art.
• A trap must be placed in the upper part of the hydraulic circuit.
• There must be a filter in the hydraulic system.
ACCESSORIES - ELECTRICAL COIL
The electric coil module uses electrical heating resistors. They are of three-phase power supply and are shown below the respective con-
nection schemes.
For proper operation and to avoid damaging the coil, the following warnings must be observed:
• Make sure that the safety thermostat is properly installed.
• All connections must be made in accordance with good art practice.
ACCESSORIES - WATER COIL FOR HEATING / COOLING
The coil modules can be used heating and / or cooling. These coil use the flow of hot and / or cold water for heating and/ or cooling.
For proper operation and to avoid damaging the coil, the following warnings must be observed:
• Check the limits of the water temperatures and the pressure of the water.
• All hydraulic connections must be made in accordance with good practice in the art.
• A trap must be placed in the upper part of the hydraulic circuit.
• There must be a filter in the hydraulic system.
