SMT-05 regulator is placed in a compact, hermetic casing, intended for wall mounting, including all
control and executive elements:
ATTENTION
The blue LED indicates the activation of the cooling / heating mode. If the LED is off, and the
regulator is connected to the mains, it means the cooling / heating operation of the regulator is
switched off. However, you can switch on the stirrer’s manual operation by pressing the button
[3].
If the regulator’s control operation is switched off, a dot is displayed on the regulator's display
(factory settings). By changing the parameter d1 (see section 6.) from the value 0 to 1, when the
regulator is switched off, the display will show the current measured temperature.
