1.1 Function of LEDS

2. MAIN FUNCTIONS

2.1 HOW TO VIEW THE SET POINT

1. Push and immediately release the SET key: the display will show the set point value.

2. Push and immediately release the SET key or wait for 5 seconds to display the sensor value again.

2.2 HOW TO CHANGE THE SET POINT

1. Push the SET key for more than 2 seconds to change the set point value.

2. The value of the set point will be displayed and the LED starts blinking.

3. To change the set value, push the or key within 10s.

4. To set new point value, push the SET key again or wait 10s.

2.3 HOW TO START A MANUAL DEFROST

Push the key for more than 2 seconds and a manual defrost will start

2.4 HOW TO LOCK THE KEYBOARD

1. Hold the and keys for more than 3s.

2. The “POF” message will be displayed and the keyboard will be locked. At this point, it will be possible only to see the set point or the MAX or Min temperature stored.

3. If a key is pressed more than 3s the ”POF” message will be displayed.

2.5 HOW TO UNLOCK THE KEYBOARD

Hold the and keys together for more than 3s, till the “POF” message is displayed.

3. ALARM SIGNALS

HOW TO VIEW THE ALARM AND RESET THE RECORDED ALARM

1. Hold the or key to display the alarm signals.

2. When the signal is displayed, hold the SET key until the “rst” message is displayed. Push the SET key again. The “rst” message will start blinking and the normal temperature will be displayed again.
