CAREL PROBES AVAILABLE:
room: code DPWC112000
•
air ducts: code DPDC112000 and code DPDC212000•
industrial: DPPC112000 and DPPC212000•
If non-CAREL probes are used, check:
voltage signal: 0 to 1 Vdc, 0 to 10 Vdc, 2 to 10 Vdc, terminal M2.1 (GND: •
M2.2);
current signal: 4 to 20, 0 to 20 mA, terminal M2.4 (GND: M2.6).•
In addition, depending on the type of power supply:
+15 Vdc, terminal M2.3;
•
+ 1 Vdc 135 ohm, terminal M2.4. •

Important:
to avoid unbalanced control, the earth of the probes or the external
•
control devices must be connected to the earth of the appliance’s
controller.
If ON/OFF terminals are not closed, all the internal and external devices •
managed by the controller will be disabled, with the exception of the
drain pump for emptying the unit after extended periods.
Note: in industrial environments (IEC EN61000-6-2), the cables
leaving the unit must not exceed 30 m in length, except for the
main probe (terminals M2 pin 1-2-3-4-5-6), the remote ON/OFF digital
input (terminal M2 pin 7-8) and cable shields for RS485 communication.
4.4 Alarm contact (M6.1 - M6.3)
Contact available for the remote signalling of one or more alarms.

Note: use clamps on the relay terminal blocks (alarm, utilities) to
prevent the cables from being detached.
