✓ LEDs signaling the current operating status of the cooling (heating) unit and the
stirrer (fan) [7] [8] [9] [10]
✓ input for connecting the limit switch,
✓ control outputs, that is:
− unit control output (heating system),
− stirrer (fan) control output.
In the figure above, the types of outputs and inputs are shown, depending on the type
of regulator.
The regulator SMT-02H v. 3, apart from cable entry through glands, has a sealing
connection of the front part of the casing with its back, which ensures splash-proofness.
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].
