TIME MODE PROG FAN The following time and temperature settings are pre-programmed into the thermostat:
Program Number 1 2 3 4 Time 6:00 am 8:00 am 4:00 pm 10:00 pm Temperature in F (C) Heat 68F(20C) 60F(16C) 68F(20C) 60F(16C) Cool 78F(26C) 85F(29C) 78F(26C) 82F(28C) COMPRESSOR PROTECTION 2. The thermostat provides a 4 minutes delay after shutting of the heating or cooling system before it can be restarted. This feature will prevent damage to your compressor caused by rapid cycling. Note that this delay also applies to the heating system control. It does not provide a delay when there are power outages. You can select the function on or off at the configuration. TEMPERATURE RANGE 3. This thermostat can be programmed between 45F and 95F (7C and 35C). However, it will display room temperatures from 30F to 99F (0C and 37C). This thermostat will automatically cutoff in Heat mode if the temperature rises above 95F (35C), and automatically cutoff in Cool mode if the temperature drops below 45F (7C). POWER SUPPLY 4. The thermostat is supplied with a Li-battery. You can charge the Lithium battery through a USB cable
(included) connected to a PC. During the charge process the battery icon will flash on and off. Note: The Lithium battery should be charged over 12 hours for the first 3 times to properly condition the battery. Low Battery Warning 5. Your thermostat has a battery warning system. When the batteries are first detected to be weak, the first stage low battery warning is indicated by battery symbol flashing on the LCD display. At your earliest convenience, you need to charge the batteries through USB. During the charging process the battery icon will flash one by one.

In SS1 and STD2 configuration, EMER mode is useless. 3This thermostat is configured from the factory to operate an electric heat or heat-pump system that requires the thermostat to turn on the fan on a call for heat. If you system is a heat/cool, fossil fuel
(gas, oil, etc.), forced air system, SELECT the HG. The HE/HG must be set to match the type of Auxiliary heat your system uses for proper operation in the EMERGENCY mode. 4) Select Energy Management Recovery OFF or ON Your thermostat is set OF from the factory. You can select ON to gradually recover the room temperature from an energy saving program to your comfort program. Therefore, the thermostat may turn your system on several minutes prior to your programmed start time. 5) Fast or Slow Cycle Selection (one stage) 6) Select Backlight function OFF or ON 7) Fast or Slow Cycle Selection (two stage) 8) Select F or C Readout. Changes the display readou t to Centigrade or Fahrenheit as required. When you change this parameter the thermostat will reset the temperature settings to it's default settings and you will have to re-program the temperature setting as your need. You can familiar with the detail step through the following section Manual Programming. 9) Selects time format display 12hours or 24hours 10) Select Compressor Lockout COMP OFF or ON Selecting COMP ON will cause the thermostat to wait 4 minutes before turning on the compressor if the heating and cooling system loses power. It will also wait 4 minutes minimum between cooling and heating cycles. This is intended to help protect the compressor from short cycling. Some newer compressors already have a time delay built in and do not require this feature. When the thermostat compressor time delay occurs, it will display Wait for about 4 minutes. 11) This mode is used to set the communication channels. There maybe Interference signal which affect the communication between thermostat and Controller. You can change the channel to avoid this.

Manual Programming Your thermostat can be programmed for weekdays and weekends, or have unique programs for each of the 7 days of the week. Use Weekday / Weekend Programs or 7-day Programming to enter or revise programs to match your Personal Program Schedule. The same steps are used when entering programs for the first time or revising programs entered during Auto Programming. Familiarize yourself with Manual Programming, so that you can easily modify your programs as your comfort needs change. The example below demonstrates the Manual Programming method. NOTE:
1. The program time can be set in 10-minute increments, and remains the same for both Heat and Cool programs. 2. The program temperature can be set in increments of 1F (1C). 3. The Heat setpoint can not be set higher than the Cool set point, and the Cool setpoint can not be set lower than the Heat set point. 4. When setting the program time, note the AM/PM indicator. 5. With the Auto Recovery feature enabled, you do not need to set your comfort program times early. Auto Recovery will determine how early to turn your system on, so that the room is comfortable at the program time.

Auto Season Changeover When the System Mode is in AUTO position, the thermostat will automatically change between Heating and Cooling systems, press UP/DOWN key to adjust the setpoint under the mode showed on the display (Heating/Cooling). Set temperature will be confirmed 3 seconds after finish your setting, and then thermostat will switch the opposite mode (Cooling/Heating) to set up the setpoint by same process, and then press "HOLD" key to exit and save temperature setting. We recommend keeping your programmed heating and cooling temperature at least 2F (2C) apart to allow the Auto Season Changeover to occur when the appropriate temperature span has been reached. There is a Designated Day Override or Permanent Override. However, these overrides are also energy saving settings. For example, you may have the following temperatures programmed at a given time: Heat Set Temp=68F, Cool Set Temp=79F. If the room temperature rises above 79F, then the thermostat will automatically change to cool mode and turn on the air conditioner. Likewise, the thermostat will automatically change to heat mode and turn on heat when the room temperature falls below 68F. Filter Monitor Your thermostat also keeps a record of the number of days that your filter has been in use. This is the actual running time. To maximize your systems performance and energy efficiency, change or clean your filter regularly. When the total fan run time reaches over 16-17 days (about 400 hours), you need clean or change your systems filter, FILTER will continue to display until the counter is reset to zero. Press to review total filter usage. FILTER displays with the total number usage in days. To reset the Filter Monitor counter, press and hold the round button for 3 seconds when the filter monitor day shows. The display will blink, and the counter will be reset to zero. Auto Recovery Auto Recovery calculates how early to turn your system back on, so that the room temperature is already comfortable by the start of the comfort temperature program period. Auto Recovery works in both Heat and Cool modes. When the thermostat is in Auto Recovery mode, the display will alternate RECO with time, and the program indicator will flash. Auto Recovery can be disabled by menu setting. Auto Recovery will not operate if Permanent hold or Temporary hold is in operation. Auto Recovery can be canceled manually if HOLD is pressed during the recovery process. Auto Recovery will be canceled and change to the next period. Keyboard lock The keyboard can be locked to prevent unauthorized changes to the thermostat. To lock or unlock the keyboard, press and hold the Run key for 3 seconds. The keyboard is locked when LOCK appears on the display. All keys are locked. Anytime a key is pressed, LOCK will appear on the screen for 1 second. To exit Lock mode press and hold the RUN key for 3 seconds. Error Mode If the thermostat is unable to control your system due to an unexpected problem, the thermostat may enter Error Mode. In this condition, the thermostat flashes E1 on the LCD display, and shuts off your system. when the display show E4 to warn, it must re-register again, E4 will disappear after registeration successed. You can set your thermostat back to the original channel to avoid re-registeration.
