Regulation Of Air Quality (Recirculation) (Mcde Module) - Evco C-PRO CLIMA SYSTEMA Installer Manual

9.3.5 Management of the dehumidifiers on/off digital inputs
The zone c-pro micro MCZN has two dehumidifiers on/off digital inputs (one for every zone)
Whenever the digital input finds the logic level "disabled", the corresponding additional
dehumidifier will be considered in OFF stare and all of the relative regulations will be disabled.
In order to make this control active the inputs must be enabled via the relevant maintenance
technician parameters.

9.4 Regulation of air quality (recirculation)
9.4.1 Regulation principle
Whenever at least one regulator for c-pro micro MCDE additional dehumidifiers is present in the
system and whenever the function is enabled, when the level of CO2 detected by the room CO2
transducer is over the CO2 set-point value plus the differential value, the MCDE regulator will
control opening of the room air recirculation damper.
It is possible to control an air circulation damper for every MCDE regulator present in the system.
Every regulation is independent and strictly linked to the reading of the CO2 transducer connected
to the MCDE regulator same.
9.4.2 Management the air circulation damper (MCDE module)
The zone air recirculation damper can be managed in three different ways, depending on the value
set via the relative Damper mode parameter available at the maintenance technician level:
-
Open: the damper is kept open independently from the active CO2 regulation.
Total renewal.
-
Closed: the damper is kept closed independently from the active CO2 regulation.
Total recirculation.
-
Modulating: the damper is opened/closed according to the specific requirements of fresh air
given by the measurements of CO2 in the room.
