Airstream TC4-2N6F User Manual

TC4-2N6F.rev.07
We strongly recommend installing supplementary natural
ventilation, a failure alarm system as well as a back-up
thermostat on at least one cooling stage (refer to the wiring
diagram enclosed with this user's manual to connect the
thermostat).
Fuses at the input and outputs of the controller adequately
protect its circuitry in the case of an overload or overvoltage.
However, we recommend installing an additional protec-
tion device on the supply circuit as well as an external relay
on all ON-OFF stages to prolong the life of the controller.
To avoid exposing the controller to harmful gases or exces-
sive humidity, it is preferable to install it in a corridor.
The room temperature where the controller is located
MUST ALWAYS REMAIN BETWEEN 32° AND 104°F (0° AND
40°C).
DO NOT SPRAY WATER ON THE CONTROLLER

SOLUTION
PROBLEM
Correct the wiring. Be sure
two different lines are connected
to each fan motor or heater: the
controller's output line L1 should
be combined with another line
(N for 115V or L2 for 230V) to
activate the fan motor or heater.
Also, be sure the stage's
COMMON is supplied by line L1.
The wiring is
incorrect.
The stage 3
fans are not
running.
or...
The stage 5
fans are not
running.
or...
The heaters are
not turning on.
The stage's fuse is
open.
Replace the fuse.
The display board
interconnect cable
is not properly
plugged into the
power supply board.
Be sure the cable is firmly
plugged in.
The fan motor or
heater is defective.
Check if the motor or heater is
defective by connecting it to an
alternate power supply. If it still
is not operating, replace the
motor or heater.
Listen to see if there is a
clicking sound when the stage
or heater-mist pilot light turns
on. If there is no clicking sound,
your controller needs repair.
The controller is
defective.
The mist is not
operating as
desired.
The mist time on and time off
are in minutes. Adjust the mist
time on and time off correctly.
The mist time on
and time off were
incorrectly adjusted.
Adjust the mist differential
accordingly.
There is a 1°F(0.6°C)
hysteresis on the
mist. See "Mist".
