How to connect the sensors
Connect the provided sensor as shown in
the diagram. For remote connections
use a standard 0.5-square millimeter
two-pole wire (one for each sensor),
taking great are over the connections, by
insulating and sealing the joins carefully. -

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).

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.
In the case of our WT1 option (water tank) will not
used, deep only the terminal side of the wetting
cover of SXPS probe.
Put SX probe (dry bulb) in the closeness.
Check periodically the sock installed on the sensor has not been clogged by calcium carbonate
scale. If so, remove it then clean or replace it.

To calibrate the %RH reading (when using the psycrometric kit):
1. Remove the wet sock from the wet temperature probe.
2.Allow the wet temperature probe to dry for 10 mins.
3.Adjust theabovesettingto makethewet bulbtemperaturematchthat ofthedrybulb.
Check periodically the sock installed on the sensor has not been clogged by
