Settings Menu
Start heat
Sets how SUNREG starts. If the unit is installed indoors, use a specific time. If the time is set to 00:00, SUNREG switches to fully automatic mode using the LDR (photoresistor). The light level setting can be found in the main menu of the automatic mode.
LDR
Heat end
Sets the time when heating will stop. This parameter depends on your local conditions. Set the time when sunlight no longer reaches the panels.
17:00
Pool circ
Determines how long it takes water to travel from the pool to the sensor. SUNREG can automatically set this value during the first startup based on current local conditions. If the pipe or hose passes through areas with different temperatures, manual adjustment is usually faster and more accurate.
Procedure: In manual mode, switch the heating valve to OFF, start the pump and a stopwatch, and monitor the temperature. When the temperature remains stable for at least 5 seconds, stop the timer and set the measured value.

15sec
Heat circ
Sets the time required for heated water from the solar panels to reach the temperature sensor. This value is determined automatically, but it can be adjusted if necessary.
Procedura: To measure the pipe length, temporarily use the sensor from the pool temperature circuit. In manual mode, switch the heating valve to ON (

Heating ON), start the pump and a stopwatch, and monitor the temperature. Wait until the temperature rises and briefly stabilizes. Very hot water may flow from the panels for a short time; record the elapsed time at that moment. Do not forget to return the sensor to its original pool water temperature sensor well.
30sec
Filtr setting
Sets when and for how long filtration runs in AUTO mode. Default is start at 18:00 for 6 hours. Adjust according to pool size and your experience. Filtration requires
Filtration on in the AUTO menu. If filtration overlaps with heating conditions, filtration stops and heating begins.
20:00, 6h
RCHK time
If the water coming from the panels is colder than the pool water, the pump will stop and another check will be performed after the set time.
30min
NTC calibration
If you use an extension cable or sensors with longer leads, you can manually calibrate the sensors. Place both sensors in an environment with the same temperature, measure the actual temperature with a thermometer, and use the UP/DOWN buttons to adjust the displayed value to match the measured temperature. Save the values. Both sensors will be calibrated. This procedure can also be used for standard manual calibration.

Wi-Fi
Configures the Wi-Fi connection for device setup and viewing data through the app. Here you can enable or disable Wi-Fi, reset Wi-Fi settings, and view network diagnostic information.
Signal strength information:
-30 to -50 dBm = Excellent,
-50 to -60 dBm = Very good,
-60 to -70 dBm = Good,
-70 to -80 dBm = Weak,
below -80 dBm = Poor

Date/Time
Sets the current system date and time of the device. If the device is connected to the internet, the date and time are automatically synchronized at every restart. The device does not automatically switch between daylight saving time and standard time.
date/time
Disp sleep
To prevent SUNREG from unnecessarily lighting up at night, you can set a period after which the display will automatically go to sleep. To wake it up, briefly press any button. The display will also turn on automatically during important operating events. Three display modes are available: always on, on from the start of heating until heating ends (
night), or automatic sleep after the set period has elapsed since the last user interaction. If the display is woken up in night mode, it will turn off again after 5 minutes.
off
Firmwr upgr
Sets whether SUNREG firmware updates should be performed automatically or whether this option is disabled. When enabled, the firmware is checked between 1:00 AM and 6:00 AM, outside the main scheduled operations (filtration, circulation). If a newer firmware version is available, an upgrade (OTA) is performed. The firmware can also be updated immediately from the app.

System overview
Displays current operating and communication parameters. Wi‑Fi status and value publication status.
Factory reset
Resets all adjustable system values back to their factory defaults.

Restart
Performs a device restart identical to pressing the Reset button on the main board or disconnecting and reconnecting the controller.
Exit MENU
Closes the menu and returns to the main screen. If left open, the system will exit automatically after a timeout.
