6.5 Probes
6.5.1
Duct temperature/humidity probe in return line
For a more accurate measurement of the temperature and humidity conditions, some specific options require that a
duct probe for sensing the air temperature/humidity is fitted in the return duct.
The probe must be connected by the installer.
The duct probe is set up for installation outdoors using a mounting flange.
It must be installed in the duct at a distance of approx. one metre from the unit. The cable for the electrical connection
of the probe is mounted in the unit return compartment.
The probe must not be installed in a position that exposes it to direct sunlight or heat radiation.
Refer to the instructions provided together with the probe and to the wiring diagram of the unit for
installation and commissioning.
The duct probe is supplied with the options below:
- temperature/humidity probe (to manage dehumidification);
- modulating submerged electrode humidifier (standard/oversized);
- hot gas post-heating coil with ON/OFF control;
