1. INTRODUCTION
1.1. Precautions
WARNING: Read and save these in-
structions!
Safety may be jeopardized if the equipment is
used in a manner not specified by the manu-
facturer. Carefully read and keep the following
instructions for future reference.
We strongly recommend installing supplemen-
tary natural ventilation as well as a backup
thermostat on at least one cooling stage.
Although fuses at the input and outputs of
the controller protect its circuits in case of
an overload or over-voltage, we recommend
installing an additional protection device on
the controller’s supply circuit.
The room temperature where the controller
is located must always remain between 32°F
and 104°F (0°C to 40°C). Indoor use only!
To avoid exposing the controller to harmful
gases or excessive humidity, it is preferable
to install it in a corridor.
If the equipment is used in a manner not
specified by the manufacturer, the protec-
tion provided by the equipment may be
impaired.
Do not spray water on the controller! In
order to clean the control, wipe it with a
damp cloth.
Before servicing or cleaning unit, switch
power off at service panel and lock the
switch disconnecting means to prevent
power from being switched accidentally.
When the service disconnecting means
cannot be locked, securely fasten a
prominent warning device, such as a
tag, to the service panel.
1.2. Symbols of the Manual
Warning. Read the following text
carefully; it contains important

Alternating current (AC).
Earth Ground Terminal
Primarily used for functional earth
terminals which are generally asso-
ciated with test and measurement
circuits. These terminals are not
for safety earthing purposes but
provide an earth reference point.
