Manual Calibration Procedures; Before You Begin Manual Calibration - Delta enteliZONE eZNT-Wi Series Application Manual

Manual Calibration Procedures

There are two methods of applying the manual calibration:
From the eZNT-Wi unit itself
l
Through enteliWEB/ORCAview via database objects
l
The thermostat should be mounted and operating in normal stable operating
conditions and powered up for at least two minutes before applying manual
calibration.
If a calibrated reference sensor is used, it should be as close to the thermostat as
possible. Avoid breathing near the sensors while measuring.
If calibration gas is used, it should be within the 400-2000 ppm range. A calibration
gas has a nominal value (e.g. 1000 ppm) but the actual certified value used in the
calibration procedure differs. The following figure shows the SC backplate that is
used for both CO2 and non-CO2 eZNT-Wi models plus the new eZNS CO2 models
with a hardware revision greater than 3.2. This SC backplate allows flush mounting
on a wall.

Before you Begin Manual Calibration:

This preparatory procedure applies to manual calibration methods I and II.
