What to Do
The MagIQtouch
controller displays
a black screen.
Unplugging/
Re-plugging the
comm’s cable
does not help.
MagIQtouch controller is
stuck in a mode where
its capacitor prevents a
proper reset.
It can happen if the
comm’s cable is
unplugged from the
controller while it was
in its early initialization
phase.
When the comm’s cable is
connected to the controller,
the screen flashes quickly
and then stays on a black
screen.
Disconnect controller and
wait for 10 minutes before
re-connection to discharge
the capacitor.
The MagIQtouch
controller display
is switching On/
Off every 0.5 sec-
ond (sometimes
faster).
The power provided to the
MagIQtouch controller is
too low.
Cable length between
the controller and the first
power source (Cooler,
Heater, Zone Control
Board) too long.
Check cable lengths:
- If direct connection be-
tween controller and appli-
ance, cable length should
not be above 40m.
- In any other cases, cable
length between controller
and the first power source
should not be above 25m.
Rectify by using cable
lengths specified in System
Diagrams provided in the
Installation manuals.
The Link Module
dipswitch is incorrectly
set.
The dipswitch adds a
diode to the power line.
If incorrectly set, it can
increase the voltage drop
on the line.
Set dipswitch according to
table printed on the Link
Module electronics board.
The MagIQtouch
controller displays
the temperature
sensed by the
controller internal
sensor instead of
the temperature
sensed by the
Master Air Sensor.
Wrong option is selected
in the “Air Sensor
Selection” option in the
General Settings menu.
The controller will also
automatically revert to
the Internal Air Sensor if
the Master Air Sensor is
faulty.
“Master Air Sensor” should
be selected in the “Air
Sensor Selection” option.
Modify selection in “Air
Sensor Selection” option.
The Link Module
dipswitch is incorrectly
set.
The dipswitch adds a
diode to the power line. If
incorrectly set it will block
power to the Air Sensor.
Set dipswitch according to
table printed on the Link
Module electronics board.
