816F fan coil temperature controller
The 829F series digital constant temperature controller is suitable for fan coil units, electric valves, electric air valves, electric air outlets, and temperature control. Using a large screen LCD display and an NTC (Negative Temperature Coefficient) temperature sensor inside the thermostat, the indoor temperature is detected and compared in real time with the temperature set by the user. The air intake of the heating and cooling system and the opening or closing of the pipeline electric valve are automatically adjusted to maintain a constant indoor temperature.
Technical parameters:
Power supply voltage: AC100~AC230V,50/60Hz
Fan load: ≤ 5A, valve load: ≤ 3A
Temperature control accuracy: ± 1 ºC
Temperature control range: 5 ºC~35 ºC
Self power consumption:< 1.5W
Dimensions: 86 * 86 * 13mm
Button Description:
Press the power button to select the system's startup or shutdown status.
M: Mode key, short press the "M" key to switch between cooling mode and heating mode.
Wind speed key, short press the "" key to switch wind speed in sequence: high speed, medium speed, low speed, automatic wind speed,
Press and hold the "" key for 5 seconds to adjust the clock.
: Use the up button to increase the set temperature or other parameter values.
: Down key to decrease the set temperature or other parameter values.
Operating instructions:
Power on/off: Press the "" button once to turn on the device, then press it again to turn off the fan coil unit and electric valve.
Temperature setting: Press the "" key to increase the set temperature, and press the "" key to decrease the set temperature.
Wind speed setting: Press the "" key to switch between high, medium, low, and automatic wind speeds in sequence.
In automatic wind speed mode, automatically switch the wind speed mode based on the room temperature and set temperature difference:
When the room temperature differs from the set temperature by 1 ºC, automatically select low speed;
When the room temperature differs from the set temperature by 2 ºC, automatically select medium speed;
When the room temperature differs from the set temperature by 3 ºC, the high-speed mode is automatically selected.
Mode setting: Press the "M" key to switch between cooling and heating modes.
Key lock: Press the "" and "" keys simultaneously for 5 seconds to lock all keys, display "", and then
Press the "" and "" keys simultaneously for 5 seconds to unlock.
Sleep function: In the power on state, long press the "M" key for 3 seconds to switch to sleep mode and display "",
Press the "" key to confirm entering sleep mode, and press the "" key to cancel.
After the sleep function is turned on, if it is in cooling mode, the set temperature will automatically increase by 1 ºC after running for 1 hour. After running for another hour, it will increase by another 1 ºC. When the total running time reaches 8 hours, it will exit sleep mode and increase by a total of 2 ºC within 8 hours; If in heating mode, the set temperature will automatically decrease by 2 ºC after 1 hour of operation, and then decrease by another 3 ºC after another hour of operation. After running for a total of 8 hours, exit sleep mode and reduce the temperature by 5 ºC within 8 hours.
Timed power on/off:
Timed startup: In the startup state, long press the "M" key for 3 seconds to display "", then short press "M"
Press the key until it switches to timed power on and displays "". The timed power on flashes for minutes, then press "M" briefly
Press the "" or "" key to switch between timed startup and hour flashing. When flashing, press the "" or "" key to set the timed startup
After setting the time, wait for the backlight to turn off and automatically confirm and save.
After the timed startup function is turned on, immediately turn off the fan and valve in the startup state to reach the setting
After setting the time, immediately turn on the fan and valve.
Timed shutdown: In the power on state, long press the "M" key for 3 seconds to display "", then short press "M"
Press the key until it switches to timed shutdown and displays "". The timed shutdown will flash for minutes, then press "M" briefly
Press the "" or "" key to switch between timed shutdown and hourly flashing. When flashing, press the "" or "" key to set the timed shutdown
After setting the time, wait for the backlight to turn off and automatically confirm and save.
After the timed shutdown function is turned on, it will automatically shut down when the set time is reached while in the power on state
Turn off the fan and valve.
After activating the timer function, press the "M" and "" keys simultaneously to check the remaining timer time.
