PRODUCT DESCRIPTION
e RDCV series are residential HVAC controllers used to control EC-fans, actuators,
lighting or other applications with an analogue (0—10 VDC / 0—20 mA / PWM) signal.
ey feature a wide supply voltage range 110—230 VAC ±10 % / 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 RDCV works as a full-featured potentiometer. e settings are
easily adjustable either via a 3-button interface equipped with a 7-Segment LED
display, via our 3SModbus software application or via the Sensistant configurator.

Before you start mounting the RDCV controller, read carefully “Safety and
Precautions”. Then proceed with the following steps:
For inset mounting
1. Disconnect the power supply.
2. Remove the frame cover of the enclosure and take the RDCV controller out, so
that it can be easily connected.
3. Do the wiring according to the wiring diagram (see Fig. 1).

ATTENTION If an AC power supply is used with any of the units in a Modbus network, the
GND terminal should NOT BE CONNECTED to other units on the network or
via the CNVT‑USB‑RS485 converter. is may cause permanent damage to the
communication semiconductors and/or the computer!

OPTIONAL MOUNTING INSTRUCTIONS
If your unit is the first or the last on the Modbus RTU network:
If your unit starts or terminates the 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).

If the output has to be PWM:
Customise the factory setting for the PWM output (if necessary). By default the PWM
output connection schematic is open collector. To connect the output to an external
voltage source via an external pull-up resistor, see Fig. 5 PWM connection example.

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 EC 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 EC motor will run at maximum speed. Press the button for 4 seconds until
the display shows a decimal point ‘.’. e RDCV is now in Stand-by mode, the output
is 0, and the motor will stop.
If this is not the case, check the connections.

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.
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 RDCV 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 RDCV 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 (see Table 1
“Adjustable parameters"). To do so, you can either use the 3-button interface
to enter the menu mode (see USER 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 RDCV in automatic mode:
e RDCV 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 RDCV 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 RDCV (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 minutes to 24 h), the RDCV returns to automatic
mode. e setting of this duration is only accessible via Modbus. e I-O adjustable
parameter should be set to “Output” (see Table 1“Adjustable parameters”).
Fig. 6 Overrule mode
■MANUAL MODE:
In Manual mode, the RDCV operates as a full-featured manual controller for EC
fans, actuators, lighting or other applications with an analogue signal (0—10 VDC /
0—20 mA / PWM). 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
(see Table 1 "Adjustable parameters"). To do so, you can either use the 3-button
interface to enter the menu mode (see USER 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 RDCV in manual mode:
e RDCV 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 RDCV is a “slave” device. is means that eventually, the
output value can be overwritten by a Building Management System.
