INTRODUCTION
1.1
Precautions
We strongly recommend installing
supplementary natural ventilation as
well as a backup thermostat on at least
one cooling stage (refer to the relay pan-
els’ wiring diagram to connect the ther-
mostat).
Although fuses at the input and outputs
of the controller protect its circuits in
case of an overload or overvoltage, we
recommend installing an additional pro-
tection device on the controller's sup-
ply circuit.
The room temperature where the con-
troller is located MUST ALWAYS RE-
MAIN BETWEEN 32°F AND 104°F
(0°C TO 40°C).
To avoid exposing the controller to
harmful gases or excessive humidity, it
is preferable to install it in a corridor.
DO NOT SPRAY WATER
ON THE CONTROLLER!
1.2
Symbols of the Manual
Caution. Read the following text care-
fully. It contains important pieces of
information which, if ignored, may

properly.
Pay attention. The following text con-
tains very useful information.
