1. DESCRIPTION.
Temperature regulators of SMT series are a microprocessor-based, programmable
temperature controllers, intended for use i.a. in milk coolers and all types of dryers.
The series includes the following regulators:
−
SMT-01,
−
SMT-02,
−
SMT-02H,
−
SMT-03.
Individual types differ from each other in the way of output of control inputs and
outputs. The casing of regulators in this series are adapted for panel mounting.

PROGRAMMING) from the value 0 for value 1, when the regulator is switched off, the display will show the current measured temperature.

5. REGULATOR FUNCTIONS. The regulator is equipped with a number of functions that, together with the possibility of creating your own program, enable adjusting the regulator's work to the individual needs of the user. Some of the functions listed below are activated after the appropriate programming of the regulator (see 6. - Page 6 − switched off stirrer (fan) operation, b. operation triggered manually: − switching on continuous stirrer (fan) operation, regardless of whether the control operation of the regulator is switched on; in order to end the stirrer (fan) operation, press the button [3], −...

- Page 8 The unit control in the cooling phase takes place depending on the temperature present in the refrigeration chamber. The regulator can control the cooling temperature in the range of -40 C up to +120 C. In order to limit the scope of the control so as to prevent the user of the cooling device from setting the temperature outside this range, set the proper parameters: b1 (limitation of the lower control temperature range) and b2 (limitation of the upper control temperature range).

The stirrer's operation can be switched off at any time by means of the [2] button (see 3. CONSTRUCTION), except when the F0 parameter is set to 2 or 3. Switching off the regulator by pressing the [1] button also turns off the stirrer operation. 7.2.2. - Page 10 8.2. The function of registering the minimum and maximum temperatures. The SMT regulator has the function of recording in its internal memory the values of maximum and minimum temperatures that occur throughout the regulator's operating cycle. This function makes it possible to check whether the milk is stored under the correct temperature conditions.
