17.4. Connection of the Enhanced c.pCOe expansion module to the control board (optional)
The management of the cooling circuit for the recovery of the
extracted air energy (optional) is done with this module.
It can also be used instead of modules with addresses 8 and 9 with
the following optional:
 Low outdoor temperature (GREAT COLD).
 Remote COOLING / HEATING.
 Proportional humidifi er or overpressure control with exhaust
damper.
 Active dehumidifi cation with condensation coil.
 Second air quality probe (CO
2
) for installation in the environment
or outdoor.
 Constant supply pressure control.
Analog inputs
U5: second air quality probe for installation in the environment or
outdoor (4-20mA / 0…5000 ppm) or air quality probe for the
zone 2 (4-20mA)
U6: di󰀨 erential pressure sensor for constant supply pressure
control
U8: suction temperature probe of the recovery circuit
U9: low pressure transducer of the recovery circuit
U10: high pressure transducer of the recovery circuit
Digital inputs
U1: remote o󰀨 of the recovery circuit
