Adjust the static pressure settings for RYB Ceiling Concealed systemsUpdated a day ago

Introduction

This article explains how to adjust the static pressure setting for RYB Ceiling Concealed systems using the Pioneer® non-programmable 5-core wired controller.

The wired non-programmable controller, which is intended for light-commercial AC equipment, can serve as a replacement for the KJR-12B controller. The controller is also compatible for old FYB012 floor-mounted mini splits. 

Steps

Follow these steps to adjust the static pressure for your RYB Ceiling Concealed system:

We recommend refraining from changing any other settings while adjust the static pressure.

Note: The AC unit must be off.

1. Press and hold the power and fan buttons until “0” displays on the thermostat screen.
2. Press the Up button until “8” displays on the thermostat screen.
3. Press and hold the power button until “CH” displays on the thermostat screen.
4. Press the Up or Down button to select your preferred static pressure. The static pressure setting goes from 1 (lowest) to 4 (highest).   
5. Press the Confirm button to set your desired setting. The display module of the indoor evaporator unit will reflect the changes.
6. Press and hold the power and fan buttons to apply the changes and exit the configuration mode.
