System Set Up
2-zone temperature control
Control option A
This option features the main remote controller, the Mitsubishi Electric
wireless remote controller and a locally supplied thermostat.
The wireless remote controller is used to monitor the Zone1 room tempera-
ture and the thermostat is used to monitor the Zone2 room temperature.
The thermostat can be also allocated to Zone1 and the wireless remote
controller to Zone2.
The wireless remote controller can be also used to make changes to the
space heating settings, boost DHW and switch to holiday mode without
having to use the main remote controller.
If more than one wireless remote controller is used, the last temperature
setting adjustment/demand will be applied to ALL rooms in same zone.
Wire the wireless receiver to FTC referring to the wireless remote controller
en
instruction manual. Turn DIP SW1-8 to ON. Before operation configure the
wireless remote controller to transmit and receive data referring to the
wireless remote controller installation manual.
The thermostat is used to set the maximum temperature for heating Zone2
room.
The thermostat is wired to IN6 on FTC. (If the thermostat is allocated to
Zone1, it is wired to IN1 on TBI.1.) (Refer to 5.1.2.)
Control option B
This option features the main remote controller, the Mitsubishi Electric
thermistor and a locally supplied thermostat that are wired to FTC.
The thermistor is used to monitor the Zone1 room temperature and the
thermostat is used to control the Zone2 room temperature.
The thermostat can be also allocated to Zone1 and the thermistor to Zone2.
The thermistor can not make any changes in control operation. Any changes
to DHW must be made using the main remote controller mounted on the
heat pump 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.
The thermostat is used to set the maximum temperature for heating Zone2
room.
The thermostat is wired to IN6 on FTC. (If the thermostat is allocated to
Zone1, wire it to IN1 on TBI.1.) (Refer to 5.1.2.)
Control option C
This option features the main remote controller (with in-built thermistor) that
is removed from the heat pump unit to monitor the Zone1 room temperature
and a locally supplied thermostat to monitor the Zone2 room temperature.
The thermostat can be also allocated to Zone1 and the thermistor to Zone2.
A thermistor built into the main remote controller can be used for monitoring
the room temperature for Auto Adaptation function whilst keeping all its fea-
tures of the main remote controller available.
The main remote controller and FTC are connected by a 2-core, 0.3 mm²,
non-polar cable (local supply) with a maximum length of 500 m.
To use the sensor in the main remote controller the main remote controller
should be detached from the heat pump unit. Otherwise it will detect the
temperature of the heat pump unit instead of room temperature. This will af-
fect the output of the space heating.
The thermostat is used to set the maximum temperature for heating Zone2
room.
The thermostat is wired to IN6 on FTC. (If the thermostat is allocated to
Zone1, wire it to external input IN1 on TBI.1.) (Refer to 5.1.2.)
Note:
Wiring for main remote controller cable shall be (5 cm or more) apart from
power source wiring so that it is not influenced by electrical noise from pow-
er source wiring. (Do NOT insert main remote controller cable and power
source wiring in the same conduit.)
