Selecting Remote Controller Functions from an ME Remote
Controller
In the remote controller function selection mode, the settings for three types of functions can be made or changed as necessary.
1) Operation mode display selection mode (Display or non-display of COOL/HEAT during automatic operation mode)
When the automatic operation mode is selected, the indoor unit will automatically perform a cooling or heating operation based on the room
temperature. In this case, AUTO COOL or AUTO HEAT will appear on the remote controller display.
This setting can be changed so that only AUTO will appear on the display.
2) Room temperature display selection mode (Display or non-display of room temperature)
Although the suction temperature is normally displayed on the remote controller, the setting can be changed so that it will not appear on the
remote controller.
3) Narrowed preset temperature range mode
The default temperature ranges are 67°F to 87°F in the cooling/dry mode and 63°F to 83°F in the heating mode.
By changing these ranges (raising the lower limit for the cooling/dry mode and lowering the upper limit for the heating mode), energy can be
saved.
*The settable range varies depending on the unit to be connected.
NOTE
On the PAR-F27MEA-US model, automatic operation mode cannot be selected while the unit is in the narrowed preset temperature range mode.
Only the lower limit can be set for cooling/dry mode, and upper limit for heating mode.

Why can control my indoor unit with centralize control

You may not be able to control your Mitsubishi Electric PURY-HP72 indoor unit with centralized control for the following reasons:

1. The power jumper connector on the outdoor unit may not be correctly set. It should be connected to CN40 on only one outdoor unit.

2. The central control switch (SW5-1) on the control board of all outdoor units must be set to "ON."

3. Address settings may not be correctly configured. The main indoor unit should be assigned the smallest address (e.g., IC00), and correct port number settings are required.

4. If using a remote controller alone, an interlock setting from the remote controller is needed.

5. Both ME and MA remote controllers cannot be connected to the same indoor unit group.

6. System controller power issues may occur if the outdoor unit fan rotates due to external forces, causing the system controller to detect an error.

7. Improper wiring or incorrect voltage at TB7 may also prevent operation.

Check each of these conditions to ensure proper centralized control.

Why can’t control indoor unit with centralize control and stay the MA control set up can’t. Control the mode

The Mitsubishi Electric PURY-HP72 indoor unit cannot be controlled with centralized control and the mode control setup does not function due to the following reasons:

1. Central control is not possible if the indoor/outdoor transmission line is used, even if TB7 terminals are daisy-chained.
2. Shielded cables must be used, and the connection must only be made after confirming the voltage is below 20 VDC.
3. Improper connection of the transmission line for centralized control, such as not correctly daisy-chaining terminals M1 and M2 or not short-circuiting the earth and S terminals on TB7.
4. If a power supply unit is not connected to the centralized control line, the power jumper connector must be moved from CN41 to CN40 on one outdoor unit—if this is not done, mode control will not function.
5. Overlapped indoor unit addresses or noise interference on the remote controller lines can also prevent proper control.
6. Failure to set one MA remote controller to MAIN or exceeding its capacity can result in control failure.

All these factors must be correctly configured for centralized and mode control to function properly.
