Connectable probes:
CAREL probes available for rooms DPWC111000
for air ducts
DPDC110000
DPDC210000
for special applications
DPPC210000
DPPC210000
Note : it is possible to connect active non CAREL probes to the
control.
Control with temperature probes
The control of this appliance features autonomous internal control, and is
connected to a temperature probe TT (Fig. 4.i).
This performs complete control according to the temperature measured
inside the environment being controlled.
Fig. 4 s shows the connection of the CAREL probe type ASET030001, with
measurement range -30T90 °C (Fig.4.s). The CAREL recommended probes
have a 0 to 1V output. The control signal must be connected to terminal
5I, whose reference (GND) is represented by terminal 6I. The control can
be connected to non-CAREL active probes.

Attention: prior to connecting the signal you must set the
parameters A0-A2-A6. See Paragraph 8.2.
Using diff erent brand probes
Diff erent brand probes can be used, with output signals selected, by
programming the parameter A2, (see tab. 4.a) from the following:
• voltage signal: 0 to 1 Vdc; 0 to 10 Vdc; 2 to 10 Vdc;
• current signal: 0 to 20 mA; 4 to 20 mA.
In addition, the maximum and minimum values must be programmed
for the signal (parameters A3 and A4 for the room probe; A7 and A8 for
the outlet probe).
The probes can be powered at the following voltages:
• 12 V stabilised at terminal 4I;
• 32 Vdc from the rectifying of 24 Vac at terminal 3I.
The control signals must be connected:
•
for the control probe HP (TT in the case of controls for steam baths) to
terminal 5I, whose reference ground (GND) is terminal 6I;
•
for the limiting probe HLP, to terminal 1I, whose reference ground
(GND) is terminal 2I.
IMPORTANT WARNINGS:
• To avoid disturbances to control, the ground of the probes or the
external regulators must be electrically connected to the ground of
the appliance’s control;
• For humidifi er operation terminals 7I and 8I must be connected by an
enabling contact or a jumper (default solution). If terminals 7I and 8I
are not connected, all internal and external devices commanded by
the control are disabled.
4.6 Alarm contact
The humidifi er’s control module features a voltage-free switching contact
for the remote signalling of the presence of one or more anomalous
events or alarms. Connection to the alarm contact (250 Vac; maximum
load: 8 A resistive - 2 A inductive) is made using the removable terminal
block H, as per Fig. 4.t.
Set up for remote indication of the presence of one or more alarms
(terminals 1H, 2H, 3H).

4.7 Final checks
The following conditions represent correct electrical connection:
1. the supply voltage of the appliance corresponds to the voltage on
the specifi cation plate;
2.
the fuses installed are suitable for the line and the voltage of the
power supply;
3.
humidifi er to be connected to a fused disconnect switch;
4.
the humidifi er has been grounded correctly;
5. the power cable is fastened to the tear-proof cable clamp;
6. terminals 7I and 8I are connected by jumper or an enabling contact;
7.
if the appliance is controlled by an external regulator, the ground of
the signal is electrically connected to the ground of the controller’.
