Units without knobs are used as indicators, optionally with remote controlled inputs /
outputs. Process control algorithms (activating of the outputs by increased / decreased
temperature, humidity etc.) must be implemented in a master controller.
Installation
Units are intended for operating in ordinary and chemically non-aggressive environment.
They do not need any servicing or maintenance. Install them in a vertical position at
places where they can be operated easily and measure correct values of temperature and
humidity, i.e. in the height of about 150 cm, with no direct sunlight or other source heat
or cold (AHU outlets, refrigerator, electrical appliances). The device consists of two parts:
bottom with screw terminal block and top cover containing PCB, display, and the knob.
The bottom part is fixed by 2 or 4 screws to any flat surface or a flush-
mounting box Ø 50
mm. There is an aperture for cabling in the back of the bottom part. The bottom should
be installed and cabling connected first, and the upper part inserted after the
construction works have been finished to prevent damage to the unit.
Seal the conduits to avoid influencing the sensor by draught. Use insulating pad when
installing the sensor on cold walls. Avoid sensor exposition to sunlight or other sources
of heat.
Opening the
cover
When removing the display part, proceed as follows:
-
press gently the side parts of the unit and pull the right of the display part by
several milimeters
-
pull the left of the display part
-
pull the display part and remove it from the bottom.
Do not bend the display part too much, the connector pins could be damaged. The locks
are only at the sides of the display part, not at the top nor bottom.
