The F mode is changed to the C mode, the corresponding indicator light is on, and the power off function is saved. .\r\n\r\nQuick Setup\r\n1.Determine the mode\r\nPress and hold SET for about 5 seconds to display P0, press SET again to display the mode.\r\nPress +- switch mode, H is heating mode, C is cooling mode\r\n2. Set the return difference:\r\nThe hysteresis is also how much the fall back after the set temperature stops. The default is 2\r\nIf you need to modify, please press and hold SET and let go for about 5 seconds to display P0, press +- to switch P1, press ST again to display the difference, press +- to set the difference back.\r\n3. Set the temperature: \r\nAfter setting the mode and hysteresis, press ENT to confirm the return. At this for time, the screen displays the real-time temperature. Press SET screen once and press +- to set the desired temperature.\r\n\r\nCode table\r\nP0: working mode (range: H/C) (default: C)\r\nP1: Hysteresis setting (range: 0.1-30) (default: 2.0)\r\nP2: Setting limit is high (range: +120) (default: 120)\r\nP3: Low setting limit (range: -55) (default: -55)\r\nP4: Temperature correction (range: +10~-10) (default: 0)\r\nP5: Delayed start (range 0-10 minutes) (default: 0)\r\nP6: High temperature alarm (-55~120) (default: off)\r\nP7: Data lock (on~off) (default: off)\r\nP8: Restore factory settings (on~off) (default: off)\r\n\r\nIn the off state, press and hold the up and down keys to quickly restore the factory settings."]
