5.5 Remote Controller Options
The cylinder unit comes factory fi tted with a main controller. This incorporates a
thermistor for temperature monitoring and a graphical user interface to enable
set-up, view current status and input scheduling functions. The main controller is
also used for servicing purposes.
This facility is accessed via password protected service menus.
To provide the best effi ciency Mitsubishi Electric recommends using automatic
adaptation function based on room temperature. To use this function a room
thermistor needs to be present in a main living area. This can be done in a number
of ways the most convenient are detailed below.
Refer to heating section of this manual for instructions on how to set
compensation curve, Flow temp. or Room temp. (Auto adaptation).
For instructions on how to set the thermistor input for the FTC please refer
to Initial settings section.
The factory setting for space heating mode is set to Room temp. (auto
adaptation). If there is no room sensor present in the system, this setting MUST
be changed to either Compensation curve mode or Flow temp. mode.
1-zone temperature control
Control option A
This option features the main controller and the Mitsubishi Electric
wireless remote controller. The wireless remote controller is used
to monitor room temperature and can be used to make changes to
the space heating settings, boost DHW and switch to holiday mode
without having to directly use the main controller.
If more than one wireless remote controller is used, the most recently
requested temperature setting will commonly be applied to all rooms
by the central control system regardless of which wireless remote
controller was used. No hierarchy exists across these remote
controllers.
Wire the wireless receiver to FTC by referring to the wireless remote
controller instruction manual. Turn DIP SW1-8 to ON. Before
operation confi gure the wireless remote controller to transmit and
receive data by referring to the wireless remote controller installation
manual.
Control option B
This option features the main controller and the Mitsubishi Electric
thermistor wired to FTC. The thermistor is used to monitor room
temperature but can not make any changes in control operation. Any
changes to DHW MUST be made using the main controller mounted
on the cylinder unit.
Wire the thermistor to the TH1 connector on FTC.
The number of room temperature thermistors that can be connected
to FTC is always one.
Control option C (Flow temp. or compensation curve only)
This option features the main controller and a locally supplied
thermostat wired to FTC.The thermostat is used to set the maximum
temperature for heating room. Any changes to DHW MUST be made
using main controller mounted on the cylinder unit.
The thermostat is wired to IN1 in TBI.1 on FTC. The number of
thermostats that can be connected to FTC is always one.
★ A single wireless remote controller may also be used as a
thermostat (rather than a room thermostat).
In such a case, the system would also necessitate wireless receiver on
cylinder unit to receive the remote controller's signal / feedback.
Note:
2-zone temperature control is not available.
2-zone valve on/off control is available.

5.6 Using SD memory card
The cylinder unit is equipped with an SD memory card interface in FTC.
Using an SD memory card can simplify main controller settings and can store operating logs. *1
Note: Before inserting or ejecting an SD memory card, confi rm that the power supply
earth cable is securely connected and prevent the FTC from being applied with
static electricity (e.g. touch a case body etc.). Otherwise, it may cause a failure of
the FTC due to the static electricity.
<Handling precautions>
(1) Use an SD memory card that complies with the SD standards. Check that the SD memory card has a logo on it as those
shown on lower right fi gure.
(2) SD memory cards to the SD standards include SD, SDHC, miniSD, micro SD, and microSDHC memory cards. The capacities
are available up to 32 GB. Choose that with a maximum allowable temperature of 55ºC.
(3) When the SD memory card is a miniSD, miniSDHC, microSD, or micro
SDHC memory card, use an SD memory card converter adapter.
(4) Before writing to the SD memory card, release the write-protect switch.
(5) Before inserting or ejecting an SD memory card, make sure to power OFF the system. If an SD memory card is inserted
or ejected with the system powered ON, the stored data could be corrupted or the SD memory card be damaged. *An SD
memory card is live for a short duration after the system is powered off. Before insertion or ejection wait until the LED lamps
on the FTC control board are all off.
(6) The read and write operations have been verifi ed using the following SD memory cards, however, these operations are not
always guaranteed as the specifi cations of these SD memory cards could change.

Before using a new SD memory card (including the card that comes with the unit), always check that the SD memory card can be
safely read and written to by the FTC controller.
<How to check read and write operations>
a) Check for correct wiring of power supply to the system. For more details, refer to section 4.5. (Do NOT power on the system at this point.)
b) Insert an SD memory card.
c) Power on the system.
d) The LED4 lamp lights up if the read and write operations are successfully completed.
If the LED4 lamp continues blinking or does not light up, the SD memory card cannot be read or written to by the FTC controller.
(7) Make sure to follow the instruction and the requirement of the SD memory card's manufacturer.
(8) Format the SD memory card if determined unreadable in step (6). This could make it readable. Download an SD card
formatter from the following site. SD Association homepage: https://www.sdcard.org/home/
(9) FTC supports FAT fi le system but not NTFS fi le system.
(10) Mitsubishi Electric is not liable for any damages, in whole or in part, including failure of writing to an SD memory card, and
corruption and loss of the saved data, or the like. Back up saved data as necessary.
(11) Do not touch any electronic parts on the FTC control board when inserting or ejecting an SD memory card, or else the control
board could fail.
(a) For insertion, push on the SD memory card until it clicks into place.
(b) For ejection, push on the SD memory card until it clicks.
