System Set Up
5.4 Remote Controller Options
The hydrobox comes factory fitted with a main remote controller. This incorporates a ther-
mistor for temperature monitoring and a graphical user interface to enable set-up, view
current status and input scheduling functions. The main remote controller is also used for
servicing purposes. This facility is accessed via password protected service menus.
To provide the best efficiency 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
en
This option features the main remote 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.
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 B
This option features the main remote controller being removed from the hydrobox and situated
in a different room. A thermistor built in the main remote controller can be used for monitoring
the room temperature for Auto Adaptation function whilst keeping all its features of the main
remote controller available.
The main remote controller and FTC can be 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 come off
from the hydrobox. Otherwise it will detect the temperature of the hydrobox instead of room
temperature. This will affect the output of the space heating. When come off the main remote
controller from the hydrobox, install the remote controller cover.
Refer to the following [remote control cover mounting method].
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 power source wiring. (Do NOT
insert main remote controller cable and power source wiring in the same conduit.)
