1. GENERAL WARNINGS
1.1 PLEASE READ BEFORE USING THIS MANUAL
• This manual is part of the product and should be kept close to the instrument for easy and quick
reference.
• The instrument shall not be used for purposes diff erent from those des cribed her eunder. It cannot be
used as a safety device.
• Check the application limits before proceeding.
1.2
• Check if the supply voltage is correct before connecting the instrument.
• Do not expos e to water or m oistur e: use the contro ller onl y with in the operati ng li m its avoiding sudd en
Temperature changes with high atmospheric humidity to prevent the formation of condensation.
• Warning: disconnect all electrical connections before performing any maintenance operation.
• Fit the probe where it is not damaged by the end-user. The instrument must not be opened.
• In case of failure or faulty operatio n send the instrument back to the distributor (see address) with a
detailed description of the fault.
• Consider the maximum current that can be applied to each relay (see Technical Data).
• Ensure that the wires for probes, loads and the po wer suppl y are separat ed an d far enough f rom eac h

5. PROGRAMMING
5.1 HOW TO CHANGE A PARAMETER VALUE MAIN MENU
1. Enter the Programming Mode by pressing the SET and DOWN key for 3s ( and
start blinking).
2. Select the required parameter.
3. Press the “SET” key to display its value (now only the
LED is blinking).
4. Use “UP” or “DOWN” to change its value.

NOTE: the set value is stored even when the procedure is exited, by waiting the time-out to expire.
5.2 THE HIDDEN MENU (PR2)
The hidden menu includes all the parameters of the instrument.
5.2.1 HOW TO ENTER THE HIDDEN MENU (PR2)
1. Enter the Programming Mode by pressing the Set + down key for 3s (
and
starts blinking).
2. When a parameter is displayed, release and re-press the SET + down for more than 7s.
3. The Pr2 label will be displayed immediately followed from the HY parameter. NOW YOU ARE IN
THE HIDDEN MENU.
4. Select the required parameter.
5. Press the “SET” key to display its value (Now only the
LED is blinking).
6. Use “UP” or “down” to change its value.
7. Press “SET” to store the new value and move to the following parameter.

5.3 HOW TO LOCK THE KEYBOARD
1. Keep pressed for more than 3s the UP and DOWN keys.
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 o MIN Temp stored
3. If a key is pressed more than 3s the “POF” message will be displayed.
5.4 TO UNLOCK THE KEYBOARD
Keep pressed together for more than 3s the UP and DOWN keys.
6. LIGHT MANAGEMENT
6.1 TIMED REGULATION: I1L = Y
With i1L = y the light remains on at least for the LHt parameter.
The LHt timer is re-initialized every time the light button is pushed.
With LHt=0 the light remains on until the light button is pushed again.
The light is switched on every time one of the following conditions happens:
• the door is open (i1F = dor)
• the presence sensor is activated (i2F = LHt)
• the light button is pushed
The light is switched off when all the following conditions happen:
• the LHt timer is exhausted
• the door is closed (i1F = dor)
• the presence sensor is de-activated (i2F = LHt)
