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 following regulators: −...
2. TECHNICAL DATA. temperature measuring range from -40 C to +120 from -40 C to +120 control temperature range (decreased by a set hysteresis) • 1 measuring resolution of the temperature C – for the range below -9,9 C and over measurer (resolution of control +100 •...

3. CONSTRUCTION. Regulator SMT is placed in a compact casing, including all control and executive elements: The regulator is equipped with: ✓ button for switching the regulator on and off [1], ✓ button disabling automatic stirrer / ventilator operation [2], ✓...

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].

4. SCHEME OF CONNECTION OF THE REGULATOR. In order to connect the regulator to the device with which it is to be controlled, the following should be done: ✓ prepare the hole in the refrigeration device to install the regulator ✓...
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 6.

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. 11.

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.

7. THE REGULATOR’S WORK CYCLE. When the regulator is connected to the mains and its operation is switched on with the button [1], it 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;...

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. ADDITIONAL FUNCTIONS. Below, some specific functions of the regulator will be described, enabling the regulator to be used for various applications. 8.1. Limit switch of the flap. The regulator is equipped with the possibility of connecting the external limit switch of the tank flap. The principle of operation of this input consists in immediately switching off the stirrer's operation at the moment of shorting or opening of this input (depending on the UU parameter setting), made by the connected limit switch of the flap.

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.

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.).
