TDST24M000SE 032635 190619

WIRING EXAMPLE ONLY FOR SOLAR CIRCULATORS IN ACCORDANCE WITH DIRECTIVE ErP 2015 WITH

EXTERNAL PWM SIGNAL.

PWM signal

WARNING!

?

Before wiring the appliance be sure to turn the mains power off.

WARNING!

S1, S2 and S3 are NTC temperature sensors. For S1 sensor the -50°C..+200°C range probe (blue cable) must be

used, while the probes with the range of -50°C..+110°C (yellow cable) can be used for the other probes.

The outputs OUT1, OUT2 and Alarm, are voltage free. It is advisable to fit a 10A 250V~ fuse on the power unit mains capable

to intervene in case of short circuits on loads.
TERMINAL BOARD GROUNDING

: On the base of the control unit case is located a brass terminal board for connecting the

ground protection conductors of the load devices connected to the control unit.

: reinforced insulation
