Sensor Mounting; Co2 Or Advanced Control Pack Sensor - Lennox eNeRGy Series Installation, Operating And Maintenance

SENSOR MOUNTING

CO2 or Advanced control pack 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.
