Introduction of SK-AC2000 display screen
The brightness of both indicators means auto-mode- A flash of illustration indicator means its operation status
Remark: SK-AC2000I Electric Room Thermostat (integral)has no auto mode; it can be only controlled with one single valve.
SK-AC2000 Remote explanation
Note:When the touch screen is pressed, the corresponding indicator will be lighted.
The touch screen and LCD screen will automatically enter dim backlight mode if no operation in 1 5 seconds. The system control and setting can be achieved completely via the remote controller. Some special functions have to be achieved only by the remote control.
PARAMETER SETTING
- Time setting: the system must be set up with remote controller. Press the SET button on the remote at first, then press the HOUR button and set up the hour,and then press the MIN button and set up minute.
- Date setting: the date setting must be set up with a remote controller. Press the SET button on the remote at first, and then press the YEAR button and set up the year; then press the MONTH button and set up the month. Press the DAY button and set up the day ( customize) .
Note: Some advanced system can be set up with the year, month and day setting with remote controller. - Minimum relay closing time setting: This feature can prevent the relay to start in the setting time, the default setting is zero ( the relay only changes as the temperature changes) . Adjust minimum relay closing time with the remote controller, press SET button twice, and use the & button on the panel to set the minimum relay closing time from 0-15 minutes when the Minute indicator flashes on touch screen.
- Room temperature drift correction: When the room temperature drifts, correct the deviation of ± 2 º C with the remote controller, press the SET button three times , use the & button and correct the deviation( increase 2 or decrease 2 ) when the temperature display flashes on touch panel.

- Unlock: the unlock function can also be achieved only with the remote controller. Press on the remote controller and unlock the system.
Note: if the power is off, this setting will be canceled. - Timing Setting :This function can be achieved air conditioning timing switch. Press SET button twice, the minute digits flash; then press the HOUR button, the hour digits will display 88: flash; set up the time with & button. If the device is shut down within 15 seconds afer setting it will restart on the setting time. If the device continues the operation after setting time, it will shut down on the end of setting time ( customized.)
- Close-fitting service : Professional user can edit timing setting, and then the air conditioning system will run in accordance with the temperature setting and time setting, this shall save time and energy, but this is paid service. Please contact local agent or our company for detail.
