1. DESCRIPTION.
Temperature regulator SMT-05 v. 3 is a microprocessor-based, programmable temperature
controller, intended for use in comprehensive servicing of milk coolers, beer wort tanks, all types
of dryers, chambers and sterilizing and pasteurizing devices, devices for producing juices, heating
of swimming pools, or for foil tunnels.
The regulator casing is hermetic (IP 65 protection class) and therefore resistant to humidity, dirt and
low temperature; electronics of the regulator is able to work in temperatures up to -10
O
C. The casing
is adapted for wall mounting.
In the set with the regulator there is a temperature sensor in the rubber cover (protection class
IP68), ended with a stainless steel sleeve. The regulator signals the failure of the temperature sensor.
A number of functions that the regulator is equipped with, as well as the ability for the user to create
his own regulator work program, make it a universal controller to manage the operation of the
refrigeration unit and the stirrer, or e.g. the heater and fan.

  • Page 3 3. CONSTRUCTION. 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.
  • Page 4 The regulator is equipped with: ✓ button for switching the regulator on and off [1], ✓ button disabling automatic stirrer / ventilator operation [2], ✓ button enabling manual operation of the stirrer / ventilator [3], ✓ digital temperature meter allowing for current temperature control, independently from switching on or off the regulator [6], ✓...

    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 section and section 9.).
  • Page 7 delaying the recording of temperature data to the regulator's memory since its activation – parameter AA. 10. The function of alarm signaling (visual and audible) of exceeding the set temperature range – parameters HA and HE. This function is connected with the possibility of delaying the time of switching on the alarm system of the regulator from the moment of its activation.
  • Page 8 6. PROGRAMMING. In order to ensure the correct working cycle of the regulator, it is necessary to program its operating parameters accordingly. By default, the controller is programmed for standard operating conditions for the purpose of controlling the milk cooler. In order to change the factory setting, enter the setting mode.
  • Page 9 7. THE REGULATOR’S WORK CYCLE. When the regulator is connected to the mains and its operation is switched on with the button [1], the regulator goes – after the delay set in parameter dE – to the control phase. The regulator controls two control circuits: control circuit for the refrigeration / heating unit;...
  • Page 10 ATTENTION If the regulator is set in heating mode, the hysteresis operation has the opposite character, i.e. the heating system is switched off after the temperature has dropped below the set value, taking into account the value of the programmed hysteresis. 7.2.

    8.2. The function of registering the minimum and maximum temperatures. The SMT-05 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.
  • Page 12 ATTENTION 1. In the absence of entries of maximum and minimum temperatures in the regulator's memory, the symbol --- is displayed. 2. Power supply loss causes the regulator's memory to be cleared. At any time, you can manually delete the current maximum and minimum values. The following figure illustrates manual memory erasing: 8.3.
  • Page 13 ATTENTION The parameter AA is identical to the delay specified in the maximum and minimum temperature recording function. In other words, the delay value set in the parameter AA will be the same for recording maximum and minimum temperature and for parameters A1 and A2. The audible alarm can be turned off by setting the HE parameter to 1 (see section 9.).
