INSTALLATION

How to connect the sensors

To connect the 2 probes use N.2 two- wire
cable 0,5 mm2 section, taking great care over
the connections, by insulating and sealing the
joins carefully. -O.C.- is displayed when the
temperature sensor wiring is open, -S.C.- is
displayed when the temperature sensor wiring
is short circuit.

How to connect the line

Connect line on terminals L-N.
Protect supply with adequate fuse.

How to connect the contacts

Connect terminals on the terminal block
(contacts up to 4AMP.AC1).
*1 Other power voltage if you required.
*2 How to connect humidity-psychrometer system (wet bulb).
WT1 Option.
Psichrometric kit with predisposition to fixing
ambient probe (SX air) and wet probe (SXPS
water). Water tank with trasparent side to
check the water level and plug for water inlet.

MAIN SETTINGS

TEMPERATURE SETTING.

Press TEMP key (key lamp flashes):
This message will be displayed instead of the
°C Set Temperature value.
Press + or - to modify. Press TEMP to confirm.

HUMIDITY SETTING.

Press HUM key (key lamp flashes):
This message will be displayed instead of the
% Rh Humidity value.
Press + or - to modify. Press HUM to confirm.

VIEWING TEMPERATURE AND HUMIDITY

With TEMP key lamp light (press TEMP key) ambient temperature is
displayed. With HUM key lamp light (press HUM) ambient humidity is
displayed (if the humidity is obtained with "wet bulb" pressing HUM for
more than 3 second on display will appear the message t.vEt in turn of
obtained value of temperature probe "wet bulb").
