1. Display Type and Functions

  • Type: LCD (segment), TN type, negative mode (light icons on dark background)

  • Backlight: White LED, turns off after 10 seconds if no button is pressed

  • Viewing angle: 12:00 – perfect for wall mounting at eye level

The screen shows important information like current temperature, mode, and program.

In normal mode, the screen shows:

  • Current room temperature or set temperature

  • Clock and day of the week

  • Selected mode (Auto, Party, Manual, etc.)

  • Icons: schedule, heating/cooling mode, battery level, key lock, RF connection, motion detection


3. Icons – What Do They Mean?

The 091Pro-RF uses many icons to show its status:

  • Temperature – current or target

  • Day of the week – Monday = 1, Sunday = 7

  • Clock – blinking colon (:), 1 time per second

  • Program bar – shows the daily schedule (Type 1)

  • Comfort mode – higher temperature (when at home)

  • Holiday mode – fixed temperature for trips

  • Party mode – temporary change, countdown with "P"

  • Manual mode – fixed temperature override

  • Key lock – prevents unwanted changes

  • Low battery – icon blinks if battery < 2.1V

  • RF – wireless communication signal

  • Motion – motion detection activ


4. Heating and Cooling Icons

The thermostat shows demand for heat or cold with animated icons:

  • Heating – flame icon blinks when heating is ON

  • Cooling – snowflake icon blinks when cooling is ON


5. Using the Display

  • When you press any button, the screen lights up.

  • While the screen is lit, pressing buttons performs their functions.

  • If motion detection is on, the screen lights up when movement is detected.

Note: This reduces battery life.


6. Start-Up and Reset

After turning on or doing a factory reset:

  • All display segments show for 2 seconds (screen test)

  • Firmware version appears (e.g. v1.2)

  • Then, the thermostat enters normal mode with default or saved settings


7. LED Icons on Receiver (RX)

The 091Pro-RF receiver (RX) has two LEDs:

  • Red LED:

    • Shows pairing, manual mode, or errors

    • Flashes or stays on depending on the status

  • Green LED:

    • Shows relay output and RF signal quality

    • ON = Good signal

    • Flashing = Weak signal

    • OFF = No signal


Summary

The icons on the 091Pro-RF display are clear and simple. They show the status, mode, and alerts quickly. Combined with a good button layout and motion detection, the thermostat is easy and comfortable to use – for everyone.
