AUTOMATIC MODE:
In
Automatic mode
the RDCZ is a “master” device, i.e. it needs to be connected to
a sensor via Modbus RTU in order to operate and control the environment based
on the information received by the sensor. If no sensor is connected, the display
will show “...” and the RDCZ will not work. The sensor needs a few seconds in order
to take samples from the environment.

Adjustment of parameters:
If necessary, some parameters, such as setpoints, can be adjusted. To do so,
you can either use the 3-button interface to enter the menu mode (see
MENU
STRUCTURE
below), use the free downloadable 3SModbus software to enter
the Modbus registers from a computer (see Modbus registers maps), or use the
Sensistant configurator.
►
Operating the RDCZ in automatic mode:
The RDCZ can be switched on and off by pressing and holding the
button for 4
seconds. The decimal point on the display indicates that the unit is in Stand-by mode.
When the RDCZZ is operational , you can toggle the display between the value
measured by the sensor and the output value (percentage) by pressing the
button.
The automatic output for RDCZ (to obtain the installed setpoint), can be temporarily
overruled by pressing and holding the up button for 4 seconds (See
Fig. 6
Overrule
mode
below). You can now manually adjust the output to the desired level. After a
predefined period of time (from 10 to 120 minutes), the RDCZ returns to automatic
mode. The setting of this duration is only accessible via Modbus RTU. The I-O
adjustable parameter should be set to “Output”.
