ESi Decades Extreme Ducted Split System and IoT Device

The ESi Decades Extreme heat pump is one of the industry’s most innovative and efficient systems, with ratings up to 20 SEER2 and 9.2 HSPF2 per AHRI standard 210/240-2023. With Ecoer’s patented technology, 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.

With the IoT device, Ecoer provides an easy way for dealers to help their customers complete registration via Ecoer Smart Service Pro App in just minutes. Then dealers can monitor the units’ live data and perform remote field settings for the condensing unit. Working alongside the Ecoer Service Team, the dealer can guarantee installation and servicing quality.

Line Sets and Charging

The Ecoer EODA condensing unit is factory pre-charged for 25ft of standard size line set and for the smallest rated indoor coil combinations. Up to 100ft of line set is allowed with a maximum of 50ft lift (see below).

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

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 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 balanced.
Check the new coefficient number to make sure you get 0.5. Basically, 0.4 to 0.6 is acceptable if SSH≤20℉.

When the LED displays “–” for more than 20 minutes, adjust the TXV opening to ensure required compressor suction   superheat (SSH>7 ℉).

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

Dip Switch SW1

SW1-1 is used to enable or disable snow sensor control.

SW1-2 selects 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.

Use minor straight screwdriver to dip switch. Must power off the unit for at least two minutes to activate the change.

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