  How it works
  
  Button control system
Press the UP or the DN button and the set temperature display will be shown in blinking mode. Once the buttons are released, the blinking set temperature display stops and the current room temperature is displayed.
  Potentiometer control system

Initially the display will show the current room temperature. When the pot is turned, the display will start to blink and show the set point temperature. Rotate the knob until the desired set point is reached and release. The display will stop blinking after a few seconds and show the current temperature.

The temperature sensor used here is a NTC [Thermistor] and is mounted on the housing. The same may be mounted externally also.

  Application
This system was designed to complement the three phase AC controllers with single phasing preventors. The unit may be mounted on the single phase preventor control panel. The unti may also be mounted close to the user for personal zone comfort setting - the controller would sense the temperature close to the user and control the AC.

Two versions allow the user choice of technology. Cost saving is acheived with the potentiometer version.

Additional requirements : Plastic housing for controller and Thermistor sensor.
