The figures show a schematic diagram of a control cabinet configuration with all devices required for full climate control of a SIMATIC HMI device.
The correct position of the components in the control cabinet and circulating air flow are essential for proper operation of the entire system.

Sample
Air circulation fan is mandatory

5. TEK – Temperature Extension Kit Functions
Controlling of internal temperature by measuring of temperatures
At panel (2a and 2b)
On surface of cabinet front (2c)
Three-step control with dynamic feedback (adaptive control)
Humidity control by measuring of rel. humidity (integrated sensor) (5)
Switch on panel (4) as fast as possible in ‘automatic’ mode
Climate controller working range from >= -20oC to <= 80oC
Cc switches on HMI panel >= 0oC
Control by user in ‘manual’ mode (8, 9)
Controlling of heating, cooling (3+10)
Controlling of fan (7)
Out of range
Cc just signalizes ‚OOR‘ from > +65oC
