− Make all necessary electrical connections as instructed in
the next section, respecting the markings of the termi-
nals.
− Fit the cover over the top of the controller and fix it in
place with the cross-head screw.

ELECTRICAL CONNECTIONS
POWER SUPPLY
The controller must be connected to a power supply of the fol-
lowing voltage and frequency: 100-240 V and 50-60 Hz.
Fit a breaker-disconnector in the power supply line to discon-
nect the controller for maintenance.

Inputs for temperature sensors
The controller has 4 inputs, each identified by a code:
S1-S2-S3-S4
are the cable terminals for the PT1000 temperature
sensors used in the selected system layout. Cable polarity is not
important.
