EVH-X SPACE 2.1 - 12.1
M0SM10N17-03
7 ELECTRICAL CONNECTIONS
Thermostat : connection up to 10m
The signal and the power supply are taken directly
from the built-in unit card.
Thermostat : connection up to 200m
Power supply taken by the trasformer (included in
the packaging) to connect to the 230/1/50
network.
The signal is taken directly from the built-in unit
card.
Type of shielded twisted duplex cable:
Min 0,5/max 1,5 mm
2
Supervision - Modbus network
MODULE RS 485 (Accessory separately
supplied)
Perform the addressing by S3, S4 S5 ; allowed
and valid addresses from 1 to 127
S3 it sets the address dozens
S4 it sets the address units
S5 it sets the address hundreds : ON = 100,
OFF = 0
S1 485 terminator : ON = termination YES
S2 line polarizer : OFF = polarization NO
Check that it is OFF on all the cards
For improve the comunication put S2 = ON on a
single card.
If more cards are polarized, faults occur
J1 RS 485 serial
J3 TTL serial
