SENSOR MOUNTING

SENSOR MOUNTING
CO2 OR ADVANCED ENTHALPIC CONTROL PACK SENSOR
The probe is delivered unassembled on the machine. The installer is responsible for mounting and connecting this sensor.
The device can be installed in dry surroundings (IP20) by screws on the wall surface or on
the standard flush mounting box. The recommended installation height is 150...180 cm.
The device position should be selected carefully. All the error factors that can affect to the
measurements should be eliminated as well as possible. The following list defines the
typical measurement error factors
• direct sun light
• occupant proximity
• air flow coming from windows or doors
• air flow coming from ventilation nozzles
• air flow coming from the flush mounting box
• differential temperature caused by external wall
NOTE: CO2 measurement causes a current peak to the supply voltage. This can produce an error to
the analogue outputs when using long and thin cables. It is recommended to increase the wire cross
section area in long cable situations (e.g. by using four-wire connection) to ensure reliable
measurement signal.
WIRING
WARNING:
Device wiring and commissioning can only be carried out by qualified professionals. Always make the wirings while the
power is switched off
For wiring of external sensors (CO2, temperature, humidity), refer to the unit-specific electrical diagram (supplied in the unit
cabinet).
AMBIENT TEMPERATURE PROBE (MATS) (C, D, E, E+ BOX)
For the wiring of the external sensors (CO2, temperature, humidity), refer
to the unit-specific wiring diagram (supplied in the unit cabinet).
