Display Overview:
- The LCD screen displays indoor temperature (from the main unit's built-in sensor) and two remote sensor temperatures (Sensor 1 and Sensor 2).
- Each temperature reading shows the current temperature, along with recorded maximum (MAX) and minimum (MIN) temperatures.
- An arrow indicator next to the current temperature shows the trend (rising, falling, or stable).
Switching Temperature Units (°C/°F):
- Press the "+/°C/°F" button on the main unit to toggle between Celsius and Fahrenheit temperature displays.
Clearing MAX/MIN Records:
- Press the "CLEAR" button to reset the recorded maximum and minimum temperatures for all sensors.
Setting Temperature Alarms:
- Press and hold the "ALARM INDOOR", "ALARM SENSOR1", or "ALARM SENSOR2" button for 3 seconds to enter the alarm setup mode for the respective sensor.
- While in alarm setup mode, the MAX or MIN alarm value will flash. Use the "+/°C/°F" and "-" buttons to adjust the desired maximum or minimum temperature alarm threshold.
- Press the alarm button again to confirm the setting and move to the next alarm value (e.g., from MAX to MIN).
- Once all alarm values are set for a sensor, press the alarm button one more time to exit the alarm setup mode.
- An alarm icon will appear on the display next to the sensor's temperature when an alarm is active.
