Press [temperature +] to increase low pressure protection recovery value and
[temperature-] to reduce low pressure protection recovery value
④, operating mode :
1. Wind supply mode: the wind speed is adjustable from 1 to 5, the temperature is not
adjustable, the green line voltage =0V.
2. Strong mode: press the panel strong icon , wind speed fixed 5
voltage
=19V,
Display and control the indoor temperature.
3. ECO mode: wind speed 1-5 adjustable, temperature 62 ℉ - -22 ℉ adjustable, green line
voltage <17V, display and control the indoor temperature.
4. Sleep
5 adjustable, temperature set 75 ℉ , green line voltage <17V, display and control the indoor
temperature.
⑤, fault protection:
1. Under voltage protection: power voltage is below the set value (default: 21.5V), speed
regulating line stops output, power low , red light on.
2. Over voltage protection: power voltage is higher than 30V, the speed regulating line stops
output, power high,red light on.
3. Temperature protection: the temperature probe is short circuit or open circuit, the speed
regulating r line stops output, display EC.
4. Fan protection: the internal fan short circuit
output, display EF.
5. The panel receives a fault from the controller, the red fault light flashes and displays the
following fault code:
wind speed 1-5 adjustable from , temperature 62℉-86℉ adjustable,
mode:
12: Controller overcurrent protection.
13: Controller blocking protection.
14: controller Under voltage protection
15: controller damage or wiring short circuit
16: Controller over voltage protection.
17: controller is continuously blocked and stopped.
18: Outdoor fan failure.
19: The pressure switch is disconnected.
20: Compressor temperature protection.
EE: Controller failure
