FCR-230
FCR230
Room controller for controlling fan-coil units
FCR-230 is a room controller intended for controlling fan-coil heaters/
coolers and thermal actuators or 3-point actuators. Installation is
directly on the wall or on an electrical connection box. The fan can be
set to one of three speeds.
FCR-230 has change-over function and can be used for 2-pipe or
4-pipe systems.
For integration into a system, FCR-230 has communication via
RS485 (Modbus, BACnet or EXOline). The device can be congured
using the application Regio tool (version 1.3-1-05 or later), which can
be downloaded from the Regin web site (www.regin.se).

Installation
Place the controller in a location that has a temperature representative for
the room. A suitable location is approx. 1.6 m above oor level in a place
with unobstructed air circulation.
Depress the locking tab in the upper edge of the controller with a
screwdriver. Carefully turn the screwdriver until the bottom plate and the
electronics unit are slightly separated (see gure 1). Then use the cutout
that becomes visible in the edge of the bottom plate to open the upper
edge completely (see gure 2). Do the same thing in the lower edge of the
controller.
Figure 1 Figure 2
Lift the electronics unit up from the bottom plate. The bottom plate with
terminals has a number of hole combinations. Select suitable holes and
fasten the bottom plate on the wall or connection box, so that the arrows
on the bottom plate point upwards. Do not tighten the screws too hard!
FCR-230
Note: FCR-230 does not indicate fan breakdown or overheating of the
heating coil. Therefore, all connections must be made externally. An
overheating protection or similar can be used to disconnect the supply
voltage.
Disconnection
FCR-230 should be connected to a switch or circuit breaker in the
building installation. This switch should be in close proximity to the
controller and within easy reach of the operator, and should be
marked as the disconnecting device for the equipment.
Always use the circuit breaker to disconnect the controller from the
mains supply during maintenance of the fan-coil and actuators.
Settings
Control modes
FCR-230 can control heating and cooling in sequence or be set to
seasonal switching between heating and cooling (change-over, see
below).
Change-over function
FCR-230 has an input for change-over that automatically resets the
output DO4 to operate with heating or cooling function. When the controller is used together with a 3-position actuator, output DO5 is also
aected by the change-over function in accordance with the above. A
sensor of type PT1000 can be connected to the input and be mounted
so that it senses the temperature on the supply pipe to the coil.
When the temperature exceeds 28°C, the output function is set to
heating and when the temperature drops below 16°C, the output is
set to cooling. As an alternative, a potential-free contact can be used.
The input function can be set to NO/NC.
To ensure satisfactory functioning when using a sensor, the system
must have continuous primary circuit circulation. When the changeover function is not used, the input must be left disconnected.
When using an electric heater and the change-over function is set to
heating, the sequence of operation for FCR-230 will be heating/heat-
ing and DO5 will be activated rst.
If a change-over sensor is not connected, the sequence will be heating/heating. If cooling is to be used in the sequence, parameter 2
(change-over mode) must be changed manually.
Operating mode
There are four dierent operating modes. Switching between these
modes is performed locally.
Comfort: is shown in the display. Heating and cooling have a
smaller neutral zone NZC. An occupancy detector can be connected
to the DI in order to select between Comfort and Economy. Switching
between Comfort/Economy and O can also be done via the On/O
button. Comfort/Economy is selected via the parameter list.
1
Economy (Standby): “Standby” is shown in the display. The heating and cooling setpoints are freely adjustable. Factory settings:
heating=15°C, cooling=30°C.
O: The controller does not heat or cool and the fan stops (unless
mould protection has been selected or the cool-down function for the
electric heater is running, in which case the fan will still run).
Window: is shown in the display, the controller is o and the fan
stops (unless mould protection has been selected or the cool-down
function for the electric heater is running, in which case the fan will
still run). The window contact is connected to the DI and must be
congured.
Occupancy detection
Parameter 3 determines if the DI is window contact input or
occupancy detection input. An occupancy detector can be connected
to the DI in order to switch between Comfort and Economy mode.
Setpoint
The setpoint is set using the INCREASE and DECREASE buttons.
Parameter 24 determines what is shown in the display. Refer to the
parameter list for details.
Setpoint limitation
In parameters 34 and 35, it is possible to set the maximum allowed
setpoint increase and decrease respectively.
Example: If P35=5 and P34=3, the setpoint can be changed between
17°C and 25°C (see the picture below).
The basic setpoint can be changed in parameter 64 (factory
setting=22°C).
Figure 3: Example of setpoint limitation
Fan control
The fan can be controlled via FCR-230 with the following modes: Low
speed, Medium speed, High speed, Auto. The current fan speed in
the Auto mode depends on the heating or cooling demand and the
settings for each speed.
When using automatic control, ”AUTO” is shown in the display.
The number of fan speed steps can be selected via parameter 30.
If the parameter is set to 1, the rst fan speed step will be used for fan
control.
Via parameter 31, it is possible to set the fan to the lowest speed level
when Auto mode is selected. If this parameter is set to 1, the fan will run
in all operating modes except O and Window (unless mould protection is
active or the cool-down function for the electric heater is running, in which
case the fan will run in these modes as well).
Manual control of the fan speed
By pressing the fan button, you change the fan speed according to the
sequence IàIIàIIIàAUTO. When using manual control, ”MAN” is shown
in the display.
If the fan has been congured not to be aected by the heating or cooling
demand, ”AUTO” will not be shown when pressing the fan button.
Indications
The display has the following indications:
HEAT Heating control
COOL Cooling control
The open window symbol is shown if this function has
been congured and a window is open.
OFF The controller does not heat or cool
On/O button
By pressing the On/O button, FCR-230 will switch between O mode
and Comfort/Economy mode.
Parameter list
When the controller is in Comfort mode or Window mode, dierent parameter values can be set in a parameter list.
Hold the INCREASE and DECREASE buttons depressed simultaneously
for about 5 seconds until the Service symbol is displayed and then press
the INCREASE button twice.
First the display will show parameter 1. Use the INCREASE and DE-
CREASE buttons to scroll between the parameters and press the On/O
button to select the desired parameter. The parameter number will then
be replaced by the parameter value. The value can be changed using the
INCREASE and DECREASE buttons. If a button is held depressed the
value will start scrolling, rst slowly and then with increasing speed.
To exit the parameter list and go back to the basic display, press the INCREASE button until “EXIT” is shown (one step before parameter 1) and
press the On/O button. You can also exit the parameter list by pressing
down the INCREASE and DECREASE buttons simultaneously.
