Precautions

WARNING: Read and save these
instructions!
Safety may be jeopardized if the equipment
is used in a manner not specified by the
manufacturer. Carefully read and keep the
following instructions for future reference.
We strongly recommend installing supplemen-
tary natural ventilation 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).
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 ser-
vice disconnecting means cannot be
locked, securely fasten a prominent
warning device, such as a tag, to the
service panel.
