Digital Room Thermostat ILH115

General Information

This type switched-mode room thermostat is suitable to regulate the overwhelming majority of
boilers available in Europe. It can easily be connected to any gas boiler or air conditioning device
that has a double wire connector for a room thermostat, regardless of whether it has a 24 V or 230
V control circuit.

Temperature can be measured more precisely as compared to simple, conventional thermostats.
In accordance with the selected switching sensitivity, the thermostat will switch the boiler or any
other appliances on and off below and above the adjusted temperature, respectively, and
contributes to reduce energy costs while maintaining comfort.

The switching sensitivity of the thermostat is ± 0.2°C (± 0.3°C). This means the difference between
the adjusted temperature and the actual temperature measured during the switching process. For
example,if the factory default setting is 20°C on the thermostat,then the device switches the boiler
on at 19.8°C or below, and switches it off at 20.2°C or above.

The information shown on the liquid crystal display of the thermostat includes the following:
