6. Room/humidity/CO
sensor
6.1

General

The wireless sensor measures temperature, relative humidity (rH) and CO
level.
The sensor is connected to the wireless network via the main product display.
This is described in menu chapter Touchscreen .
The table in the chapter Technical data shows factory settings for threshold
start/stop values for carbon dioxide level and relative humidity in ventilation
modes Forced and Customised. For instance, ventilation mode Forced starts
when the carbon dioxide concentration is 1,000 ppm during a sampling
interval and it stops when the level falls to 800 ppm. If multiple sensors are
installed, the highest measurements (rH, CO
and compared with the threshold values.
During installation, threshold values should be adjusted for conditions in the
home. For more information, please see Installation and Maintenance Manual
for the ventilation unit.
6.2

Installation

For accurate measurements, the sensor should be placed in a location which
is representative of conditions in the home.
• Remove the base plate by pushing in the latch on the bottom of the
sensor with a screwdriver. Gently remove the cover by twisting.
• Connect the wires from the power supply to the terminal block on the
base plate (see photo) and mount the base plate on the wall using
screws. It is possible to create a lead-through for the wires in the base
plate by cutting off some of the plastic.
• Push the cover onto the base plate.
• Connect the power supply cable to the wall socket.
