ecoer EG910L Inverter Ducted Split System

Product Information

The Ecoer Smart Inverter (ESI) Ducted Split System is an innovative and efficient heat pump system with ratings up to 20 SEER and 10 HSPF per AHRI standard 210/240-2017. The ESI heat pump automatically adjusts itself while maintaining constant and consistent speeds to avoid temperature swings. Compared with fixed-speed systems, Ecoer inverters have a much wider capacity range which helps to achieve faster heating and cooling. With more than 30 variable stage settings, Ecoer inverters provide more accurate and efficient temperature control while using less energy. Additionally, the IoT device allows dealers to help their customers complete registration via Ecoer Smart Service Pro App in just minutes. The dealer can also monitor the units’ live data and perform remote field settings for the condensing unit.

  • The standard line set is recommended, N/A: Not allowed

The refrigerant charge is suggested to be done by the following methods:

Charge by Weigh-In

Can be used for the initial installation, or anytime a system charge needs to be replaced. This method can be used when power is not available on the job site or the ambient temperature is improper to use refrigerant coefficient and subcooling. A refrigerant adjustment may be necessary if the line set length is over or under the pre-charged 25ft (adding or removing 0.6 oz/ft on 3/8 liquid line respectively). An additional amount of refrigerant adjustment may be required for a large indoor coil.

Charge by Refrigerant Coefficient

Ambient temperature must be between 50ºF and 120ºF and indoor temperature must be kept between 70ºF and 80ºF. After starting the system in cooling mode, Press and hold BS4 button for five seconds until SEG1 displays blinking 7, and operate the system for a minimum of 20 minutes. Check the refrigerant coefficient number (here short for “X”, 0<X<1) on the display. If X>0.6, remove refrigerant; or X<0.4, add more refrigerant. Then wait for 5 minutes to allow pressure to balance. Check the new coefficient number to make sure you get 0.5. Basically, 0.4 to 0.6 is acceptable if SH≤20゜F. When the LED displays “–” for more than 20 minutes, adjust the TXV opening to ensure the required compressor suction superheat (SH>7 ゜F).

Exit Charge Mode: Press BS4 once or After 2 hours running or Turn off the system at the thermostat

Control Board Settings

In most scenarios, it is recommended to keep all outdoor unit board dip switch positions in their manufacturer default positions. There are some specific scenarios when it makes sense to change dip switch settings.

ecoer-EG910L-Inverter-Ducted-Split-System-FIG-8

Dip Switch SW1

  • SW1-1 sets the Snow Sensor Control mode.
  • SW1-2 selects the Tonnage of the condensing unit.
  • SW1-3 sets Air Conditioner or Heat Pump

SW1-4 is suggested to remain in the factory default position (OFF). IoT command responses such as remote field setting, troubleshooting, software programming etc. only work when this switch remains in the OFF position.

Must power off the unit for at least two (2) minutes to activate your dial of switches.
