PRESENTATION

Dear Customer, thank you for choosing our product.
The thermostat, suitable for all heating and/or cooling system, is fitted with a large and clear backlit display to keep all its functions under control in real time. The fundamental feature is its easy to use menu navigation, which makes it extremely user-friendly despite its comprehensive range of functions. The thermostat is factory-set to adjust temperature in a modulating Proportional operation may be selected with settable duration cycles (from 7 to 20 minutes): this system ensures the desired temperature is maintained more stable, increasing user comfort and is particularly suitable for installations with high thermal inertia such as, for instance, for underfloor radiant panels; alternatively it is possible to select temperature regulation in Differential ON/OFF mode with the hysteresis settable from 0.2°C to 1.2°C to adapt to the thermal inertia of your specific system. The set temperature scale is in degrees Centigrade with the option to calibrate room temperature measurement setting a correction value (from -6 to +6 °C). Special attention was devoted to energy saving: optional Set temperature (MAX/MIN) lock, adjustable antifreeze/thermal protection temperature value, control through an remote external contact, are conducive to avoiding wasting energy with consequent savings.
WARNINGS!
Read this manual carefully before using the product as it provides important guidelines regarding safety, installation and use.
& The manual must be preserved with care for future reference. The manufacturer reserves the right to make all the technical and construction changes it deems necessary without prior notice.
The installation and electrical connection of the programmable thermostat must be implemented only by a qualified electrician and in conformity with current laws and regulations.
Before starting any operations on the device, disconnect the 230V~ mains power supply
The thermostat is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or by those with a lack of experience and knowledge of the instructions, unless they are supervised or have received the necessary instructions concerning use of the device by a person responsible for their safety. Children should be supervised to ensure that they do not play with the device. If 0.0 °C or 45.0 °C room temperature flashes on the display, the measured temperature is beyond the scale, the device is still operational. In the event of a temperature probe failure, code E1 will be shown on the display (see par. 11). IMPORTANT: in case of a power black-out (230V~), the thermostat guarantees retention in memory of all the data entered. When mains power is restored, the display turns on and the device returns to the active operating mode before the power failure. If necessary, gently clean the thermostat and the display with a soft, dry cloth.
