7.4.2 Type H control module with modulating action
The humidifi er with modulating action is fi tted with solid-state relays, and its capacity can be varied from
zero to 100% depending on the control requirements. In this case too, the humidifi er can be
connected via RS485 to the CAREL Humivisor MT remote control panel or a remote supervisor. It can be
controlled in the following three different modes.
Slave control, with signal from an external regulatora) .
Steam production is managed by an external regulator R (Fig. 7.d) that transmits a modulating
signal to the control module; the control module can be programmed to receive alternatively one of
the following modulating signals (see THE HUMIDIFIER CONTROLLER):
voltage signal: 0 to 1Vdc; 0 to 10Vdc; 2 to 10Vdc;•
current signal: 0 to 20mA; 4 to 20mA.•
The reference (zero) of the external regulator must be connected to terminal 6I on terminal block I and
the control signal to terminal 5I (Fig. 5.e).
To avoid disturbances in control, the ground of the external regulator must be connected to the ground
of the control.
Autonomous modulating control with ambient relative humidity probe (and possible limiting probe b)
in the outlet duct)
With this confi guration (see Fig. 7.f) the main control board, connected to a humidity probe HT,
performs complete control according to the humidity measured.
A limiting humidity probe in the outlet duct can also be added (see Fig. 7.g): with this confi guration,
typical of air handling systems, the main control board, connected to a humidity probe HT, perfor-
ms complete control, as well as limiting the steam production depending on the value of relative
humidity in the outlet duct, measured using the special probe CH.
The diagrams shown in Fig. 7.h indicate the connections to be made using CAREL probes, for:
just one relative humidity probe;•
a limiting humidity probe in the outlet duct.•

7.4.3 Type T control module for steam baths with modulating action
The control of this appliance features autonomous internal control, and is connected to a temperature
probe TT (Fig. 7.i).
This performs complete control according to the temperature measured inside the environment being
controlled.
Fig. 7.4.3.2 shows the connection of CAREL probe model ASET030001, with a measurement range of
-30T90 °C (Fig. 7.j.A), or SST00B/P40 (Fig. 7.j.B). 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; see Using different brand
probes.
