Control Module T For Steam Baths With Modulating Action; Other Auxiliary Contacts; Alarm Contact; Dehumidification Contact - Carel heaterSteam User Manual

The diagrams shown in Fig. 7.5.2.5 indicate the connections to be made using Carel probes, for:
a) just one relative humidity probe;
b) a limiting humidity probe in supply duct.

7.6 Other auxiliary contacts

7.6.1 Alarm contact

The humidifier'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 (250Vac; maximum load: 8 A resistive - 2 A inductive) is
made using the removable terminal block H, as per Fig. 7.6.1.1.

7.6.2 Dehumidification contact

In the advanced version with internal regulation and humidity transducer, the control
module features a voltage-free NO contact, the closing of which can, if required, be
programmed to activate an external dehumidification device: in this case the appliance
assumes the functions of a complete ambient relative humidity control.
Connection to the dehumidification contact (250Vac; maximum load: 8 A resistive - 2 A
inductive) is made using the removable terminal block G, as per Fig. 7.6.2.1.

7.6.3 Remote terminal / supervisory system

The humidifier's control module can be connected to an RS485 serial line, as per the
diagram in Fig. 7.6.3.1, or alternatively to:
a Carel Humivisor remote control panel (see specific instruction manual), which can be
connected to four different humidifiers;
a remote supervisory system.
The transmission line can reach a maximum distance of 1000 metres between the two most
distant points.

The control of this appliance features autonomous internal regulation, and is connected to a
temperature probe TT.
This performs a complete regulation action according to
the temperature measured inside the environment being
controlled.
Fig. 7.5.3.2 shows the connection of Carel probe model
ASET030001, with a measurement range of -30 90 °C,
or SST00B/P40.
The command signal must be connected to terminal 5I,
whose reference (GND) is represented by terminal 6I.
