PRODUCT DESCRIPTION
e RDCZ series are residential HVAC controllers used to control AC fans or voltage
controllable motors in HVAC applications. ey feature a wide supply voltage
range 110—230 VAC / 50—60 Hz and a variable control output signal between
an adjustable minimum and maximum level. e controller can work in 2 modes.
In Automatic mode it is a demand-based controller with adjustable setpoint that
can be connected to a broad range of Sentera sensors. In Manual mode, the RDCZ
works as a full-featured triac controller. e settings are easily adjustable either via
the 3-button interface equipped with a 7-Segment LED display, via our 3SModbus
software application or via the Sensistant configurator.

from section “Wiring and connections”.
7. Put the internal enclosure into the external one and fix it using the delivered
screws and washers. (Fig. 4).
8. Put back the frame cover of the enclosure.
9. Switch on the power supply.
10.Customise the factory settings to the desired ones via the 3-button interface,
the 3SModbus software or Sensistant.
Optional settings
If your unit is the first or the last unit on the Mdbus RTU network (see Example 1 and
Example2), enable the NBT resistor via 3SModbus or the menu of the controller. If
your device is not an end device, leave the NBT disabled (default Modbus setting).

OPERATING INSTRUCTIONS
Choosing the operating mode
To choose the desired operating mode, press the up and down buttons
simultaneously in order to access the Setup mode. e decimal point after the values
indicates that the unit is in Setup Mode.
e display shows “RUN”. To change the run mode, press the button. Use the up
and down buttons to select “1” for automatic mode or “0” - for manual mode.

back to the table of contents
To save the selected mode press for 4 seconds. The display will show "888" for a
few second to indicate that the value is stored in the memory. Press the up and
down buttons simultaneously again in order to exit the Setup mode.
■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. e 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:
e 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.
e 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. e setting of this duration is only accessible via Modbus RTU. e I-O
adjustable parameter should be set to “Output”.

■MANUAL MODE:
In Manual mode, the RDCZ operates as a full-featured manual controller for AC
fans.. e output value increases / decreases in the range between the min. and
max. settings (or 0). See the operational diagram. e output can be stepless or
divided into 2—10 equal steps.

►Adjustment of parameters:
If necessary, some paramaters, such as the number of steps, 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 manual mode:
e 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.
To increase the output value or step, use the up button. To decrease the output
value or step, press the down button.
When the number of steps is > 0, you can toggle the display between the number of
steps and the output value (percentage) by pressing the button.
NOTE In manual mode, the RDCZ is a “slave” device. is means that eventually, the
output value can be overridden by a Building Management System.

VERIFICATION OF INSTALLATION INSTRUCTIONS
When you first switch on the mains supply, the display will show “888” for 2 seconds.
en, ”20” will appear and the connected AC motor will run at minimum speed.
If this is not the case, check the connections.
Press and hold the up button until you reach the maximum output value ‘100’.
e AC motor will run at maximum speed. Press the button for 4 seconds until
the display shows a decimal point ‘.’. e RDCZ is now in Stand-by mode, the output
is 0, and the motor will stop.
If this is not the case, check the connections.
