INSTALLATION
SAFETY REQUIREMENTS
- The installation and assembly of electrical equipment must be performed by expert personnel.
- Before connecting the thermostat make sure that the load (pumps, valves, boiler, etc …) are not powered-up and are within the rating of the contact.
POSITIONING
Install the thermostat away from heat sources (radiators, direct sunlight, kitchens) and doors/windows. Mount about 1.5 meters above floor level.
FIXING
Use screws 0 3.5 mm. Maximum head thickness 3 mm. When fastening, take care not to over tighten the screws to avoid distorting the base.
NOTE
Use only a damp cloth for cleaning.
- Insert the batteries into the battery compartment, respecting the indicated polarities.
CAUTION Incorrect positioning of the batteries (polarity inversion) can damage the thermostat. - The thermostat is provided with 2 battery thresholds: the first threshold indicates that the batteries are low and must be replaced. In this condition, the display in the off state and a flashing battery icon will show every 5 sec.
- After touching the Finder button and turning on the display, the battery icon will continue to flash.
- At the second threshold, the thermostat turns off, the output relay will be set to OFF and it will no longer be possible to make any further adjustments.
In this condition, the flashing battery icon can be seen every 5 seconds (until the batteries completely run out). - Touching the word “Finder” to turn on the thermostat results in BAT and OFF alternating on the display.
