Programmable modulating room thermostat "OpenTherm" (wired) iSense S103293

The iSense S103293 thermostat is a programmable controller that precisely adjusts the operation of the heating and domestic hot water system to actual needs. Thanks to OpenTherm communication, it provides boiler power modulation, which translates into energy savings and thermal comfort. The device is designed for wired installations and offers a wide range of configuration options for both professional installers and end-users.

Comfort and savings in one device

The iSense S103293 controller not only maintains the set temperature but also optimizes fuel consumption. Boiler power modulation avoids unnecessary overheating or underheating of rooms, which directly affects lower heating bills. Additionally, the ability to program a weekly schedule allows you to adjust the temperature to the individual lifestyle of household members.

• Automatic mode: Allows programming different temperatures for individual time slots during the week – ideal for people with a fixed daily routine.
• Constant mode: Allows maintaining a constant temperature during the day, at night, or setting an anti-freeze temperature – useful in situations where a constant temperature is required.
• Vacation mode: Allows setting the start and end date of the vacation and the maintenance temperature – ideal during a longer absence from home.

Flexibility and extended possibilities

The iSense S103293 thermostat offers a wide range of setting parameters for different types of boilers, such as heating characteristics, maximum boiler temperature, or fan speed. In versions 288 and 289, there is also a function of energy counting (number of hours of pump operation, DHW, total), which allows for a detailed analysis of energy consumption. The ability to connect an external temperature sensor (AD 225 or FM 46 package) allows for even more precise adjustment of the heating system operation to weather conditions.
