Indoor air quality sensors
Indoor air quality sensors (IAQ) are CO
2
, relative humidity and temperature
transmitters that must be installed either in extract air duct or the room de-
pending on the type of transmitter.
• IAQ — indoor air quality sensor (CO
2
, RH and
temperature)
• CO2 — CO
2
duct sensor
• 1 — Outdoor air
• 2 — Supply air
• 3 — Extract air
• 4 — Exhaust air
Component/product — Article number:
• Systemair-1 CO2 duct sensor — 14906
• Systemair-E CO2 sensor — 14904
• Room sensor 0-50C (temperature) — 211525
• Systemair-E CO2 RH Temperature — 211522
Fig. 10 IAQ connections
Installation and connection
1. Install IAQ sensor in the duct or the room depending on
the transmitter type.
2. Connect CO
2
sensor to any free universal analog input
(UI) on the connection board.
3. If IAQ sensor contains relative humidity transmitter:
Connect it to any free universal analog input (UI) on the
connection board.
4. If IAQ sensor contains room temperature transmitter:
Connect it to any free analog input (AI) on the connec-
tion board (only AI6 and AI7 are available on the con-
nection board).
Configuration
1. Go to
Service
menu.
2. Enter password (default 1111).
3. Configure of CO
2
and/or relative humidity sensor: Go to
Input
menu. Select
UNIVERSAL
tab. Select the universal in-
put to which the sensor is connected. Example if it is connected to UI4 on the connection board, then select
UNIVER-
SAL INPUT 4
. Select signal type as
Analog input
and select sensor type from the input type list:
RH sensor (RH)
and/or
