The digital thermostat is ideal to control the temperature of any room(bedroom, kitchen, etc.) and is very easy to use. Allows for the operation of heating / cooling equipment, when the temperature of the environment to be monitored is lower/higher than a user-preset reference temperature. Very easy installation according to the step by step manual instruction. Mounting and connection can be made either by a technician or any other person.


IMPORTANT: carefully read the manual of use before the installation and follow the precautions when using the product.


Precautions on battery use

  • Use only batteries of indicated size and voltage.
  • Make sure you plug the batteries observing the correct polarity as indicated in the battery compartment. Battery connection with incorrect polarity may damage the thermostat.
  • Do not mix different types of batteries such as an alkaline and a zinc carbon, or old batteries with new batteries.
  • If you expect not to use the thermostat for a long period, disconnect it from the equipment and remove the batteries to prevent damage resulting from possible battery leakage.


Precautions on installation and use of the thermostat

  • The digital thermostat is exclusively for indoor use (closed rooms, garages, porches etc.). Do not install outdoor or in locations directly exposed to rain.
  • Do not install in places with high humidity.
  • The thermostat can operate one device only. The connection of several equipment in cascade or in series (for example, a heater and a fan) does not guarantee the correct functioning of the device.
  • Cut off mains power before connecting any device.
  • Use the utmost caution when making wirings for connection with equipment and electricity mains: a wrong connection or unreliable shielding of electrical cables may cause damage to the device and jeopardize your safety.


Note: the manufacturer waives any responsibility for damage caused by improper installation or use of the device other than described in this manual.
