CONTROL WITH TWO ACTIVE TEMPERATURE PROBES
• short-circuit terminals M2.7 – M2.8 (jumper) to enable production;
alternatively connect terminals M2.7 – M2.8 to a remote contact (e.g.:
switch, timer,...);
• connect the main active room probe to terminals M2.1, M2.2 (GND)
and M2.3 (+12Vdc);
• connect the second active probe to terminals M2.5, M2.3 (+12Vdc) and
M2.6 (GND);
• to enable control, set:
Screen ind. Screen desc. Parameter
Ea01 Control type Temperature (two probes)
Ea02 Control with 2 probes Set the weight of the two probes (0-100%)
Ea05 Modulating control Set: temperature set point (0-100 °C) (32-
212°F)
diff erential (2-20°C) (3.6-36°F)
Minimum production (0-100%)
Maximum production (0-100%)
Ec01 Main probe type Select from: 0-1V, 0-10V, 2-10V, 0-20mA,
4-20mA
Ec02 Second probe type Select from: 0-1V, 0-10V, 2-10V, 0-20mA,
4-20mA
The controller will calculate the weighted average between the two
probes. The weight of the two probes can also be set.

The following probes can be connected:
CAREL probes for rooms DPWC111000
for air ducts DPDC110000; DPDC210000
for technical applications DPPC210000, DPPC210000
Note:: non-CAREL active probes can be connected to the controller.

CONTROL WITH ONE NTC TEMPERATURE PROBE (passive)
• short-circuit terminals M2.7 – M2.8 (jumper) to enable production;
alternatively connect terminals M2.7 – M2.8 to a remote contact (e.g.:
switch, timer,...);
• connect the main NTC room probe to terminals M2.1, M2.2;
• to enable control, set:

4.8 Alarm contact
The humidifi er controller is fi tted with a relay contact for remote signalling
of one or more faults or alarms. The alarm contact (250 Vac; max capacity: 2
A resistive - 2 A inductive) is connected to terminals M6.1, M6.2 and M6.3.
