This thermostat is designed for modern fan coil units with EC fans in both 2-pipe and 4-pipe systems. It provides specific control for heating valves, cooling valves, and the EC fan motor.
The device is available in black or white versions. All models measure temperature and humidity, while some variants also include optional CO2 measurement.
The device measures temperature from 0 to +50 °C with an accuracy of ±1 K. Relative humidity is measured from 0 to 100% rH (non-condensing), with an accuracy of ±2% within the range of 10% to 90% rH. For variants equipped with the optional CO2 sensor, the measurement range is 0 to 2,000 ppm with an accuracy of ±5% of the measured value plus 50 ppm.
The thermostat features one 0..10 V output (max. 5 mA) for controlling EC fans and two normally open switch contacts for heating and cooling valves, supporting a maximum load of 3 A at 24 V.
The device is designed for flush mounting in standard EU boxes (60 mm diameter) and requires a 24 V AC or DC (±10%) power supply. It has an IP30 protection rating and a power consumption of approximately 3 W.
Configuration can be managed through the uConfig software for Windows via a microSD card or remotely via LoRaWAN Downlink commands. Data transmission behavior can be set based on heartbeat intervals, value changes, or hysteresis.
