BATTERY

Insert the batteries into the battery compartment, observing the correct polarity.

Exterior view of a black rectangular electronic device with a cylindrical battery and labeled ports (no readable text or symbols beyond branding)

ATTENTION

• Incorrect placement of the batteries (reverse polarity) may damage the thermostat
• If the battery charge falls below the minimum level, the thermostat is placed in the OFF state and the output relay releases
• If the thermostat remains unused for long periods it is advisable to remove the batteries
  The thermostat provides 3 different reports of battery condition:

BAT

• With the battery ON (STEADY), operation of the thermostat will soon be compromised
• With the battery FLASHING imminent replacement of batteries is necessary
• With the bRt/OFF FLASHING the thermostat is in the OFF state and the output relay releases

NOTE

Replacing the batteries at the initial warning ON (STEADY) and taking no more than 40 seconds, the date and time will not be erased.

START UP

Insert the batteries and for a few seconds the display will show all the symbols, keys and the software version - before entering the time and date routine. Set the latter by using the keys △ ▽ to modify the values and OK to confirm (see pages 10/11).

After that, the thermostat will revert to the main screen:
