.
The dehumidifier has 2 modes of operation, the choice of which is carried out by the operator
using
3 position switch
(Rocker Switch) on the control panel
:
When installing a temperature sensor temperature and humidity (sensing element),
its mounting position must comply with the following requirements:
•
Temperature and humidity sensors should be installed at a distance of 1-1.5 m from
the ground so that the sensor measures the humidity level in the area being dried
;
•
Sensors should be installed away from dry/moist air flow or air flow from the environment
;
•
Temperature and humidity sensors should be installed away from refrigeration equipment
;
•
Do not install the sensors in a place exposed to direct sunlight, as temperature changes
may affect the measurement process
.
The scheme for connecting an external temperature and humidity sensor to the controller
is shown in the general wiring diagram of the installation. Characteristics of sensors and terminals
for connection are also specified in the section with description of controller terminals
.
