CONTROL WITH TWO HUMIDITY 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 Modulation with two humidity probes
Ea02 Control with 2 probes Set the weight of the two probes (0-100%)
Ea05 Modulating control Set:
humidity set point (0-100 %rH)
diff erential (2-20%rh)
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.
4.7 Control with temperature probes
The controller features independent internal temperature control,
and can be connected to a temperature probe TT (Fig. 4.r). It performs
complete control based on the temperature measured inside the
controlled environment.
