Air conditioner
control Air conditioners continue to work in cool mode
though the room temperature is lower than the
lower limit set up by the Temperature Limit function. Check whether the subject indoor
units have Changeover Option. The subject indoor units are
controlled by an upper unit with
Changeover Option. Check the Temperature Limit settings.
Air conditioners continue to work in heat mode
though the room temperature is higher than the
upper limit set up by the Temperature Limit function. Check whether the indoor units have
Changeover Option. The subject indoor units are
controlled by an upper unit with
Changeover Option. Check the Temperature Limit settings.
Indoor units working in automatic
mode switches to heat (cool) mode
spontaneously. Check in the history whether the
Temperature Limit function is running. The subject indoor units are controlled
by the Temperature Limit function. Check the Temperature Limit settings.
Check in the history whether the Auto
Changeover function is running. The subject indoor units are controlled
by the Auto Changeover function. Check the Auto Changeover settings.

switching between cool and heat
modes is according to the Schedule
function. Switching between cool and heat modes
is controlled by a schedule program. Check the schedule program.
Check the history whether switching
between cool and heat modes is according
to the Interlocking Control function. Switching between cool and heat modes
is controlled by an interlocking program. Check the interlocking program.
Check the history whether switching between
cool and heat modes is carried out manually. Switching between cool and heat
modes is carried out manually.
PPD Cannot connect iTM to PPD
engineering tool. When iTM and PC are connected via
hub, check whether they are correctly
connected. PC is not connected with iTM. Connect the iTM and PC via hub
using LAN cables.
Cross cables are used as the LAN cables
connecting the iTM and hub, and PC and hub. Use straight cables as LAN cable for
connecting the iTM and PC via hub.
The hub is turned off. Turn on the hub.
Check that iTM is turned on. The iTM is turned off. Turn on the iTM.
Check whether the network settings
on the PC are in conformity with the
settings described in this manual. The network settings on the PC are
incorrect. Modify the network settings on the
PC so that they are in conformity with
the settings described in this manual.
When iTM and PC are connected
directly, check whether they are
connected using the correct cable. The LAN cable connecting the iTM
and PC is a straight cable. Connect the iTM and PC using a
cross cable.
A Firewall is installed on the PC. Disable or delete the Firewall on the PC. (Be

The pulse port is not displayed on the
PPD setup tool. Check whether the Pi management
point is registered in iTM. Pi management point is not registered. Register the Pi management point.
When trying to run a trial for the set
up model on the PPD engineering
tool, some of the indoor units are not
automatically recognized. Check whether the management
points registered in iTM are
experiencing communication error. Indoor units are experiencing
communication error. Find and solve the cause of the
communication error in the indoor
units.
Check whether the subject indoor
units are included in the model
database. The subject indoor units are not
included in the model database. Check whether the engineering tool
is the latest.
Check with System Support if they
are supported models.
If they are supported models, ask their capacity
and actual state. If they are models that must
be set up manually, set them up manually.

The pulse value does not increase
for the displayed management point. Check the port number to which the
pulse signal wire is connected. The pulse signal wire is not
connected to the correct Pi port. Connect the pulse signal wire to the
correct Pi port.
Check whether the detected kWh is
increasing. The detected kWh is not increasing. Check whether the kWh meter is
correctly connected.
The total pulse value at the iTM does
not match the detected PPD value. Check the history whether a power failure signal
has been input while iTM was being reset. The pulse value has been partially
lost while iTM was being reset. Give explanation to users.
Check the PPD engineering tool
settings. PPD was set to not distribute the
consumed power while the air

problem, after consulting with the users,
modify settings to distribute the consumed
power while the air conditions are stopped.
Consumed power has been
distributed though operation time for
the subject indoor unit is “0”. Check the PPD engineering tool
settings. PPD was set to distribute the
consumed power also while the air
conditioners are stopped. Check the PPD settings. If there is any
problem, after consulting with the users,
modify settings to not distribute the consumed
power while the air conditions are stopped.
Consumed power is “0” though the
subject indoor unit is operating. Check the operation mode of the
indoor unit. The operation mode was fan mode. Check the PPD settings.
The thermostat was always OFF
though the air conditioner was
operating in cool or heat mode. Check the PPD settings.
