If the compressor or fan icons are blinking, it typically indicates a delay (e.g., minimum off-time) is active before the device will start. 4. Programming Parameters
Monitors and controls temperatures from -50 °C to +150 °C . Front panel protection is rated up to IP55
Supports standard Carel NTC (10 kΩ at 25 °C) and PTC (985 Ω at 25 °C) probes.
Avoid installing probe cables near contactors or circuit breakers. If extension is needed, use cables with a minimum cross-section of 0.5 mm² . After modifying values with the arrows, you must
By default, the display shows the temperature from the primary probe (B1). Changing the Set Point: Press the SET button briefly. Use the UP and DOWN arrows to adjust the desired value. Press SET again to confirm and save.
Correct installation is critical to prevent electromagnetic interference and hardware failure.
Store and operate the device within the specified temperature and humidity limits to prevent internal condensation or damage to plastic components. 3. User Interface & Basic Operation
