Room controller for controlling fan-coil units
RCFM-230TD is a room controller intended for controlling fan-coil
heaters/coolers and thermal actuators or 3-point actuators. Instal-
lation is directly on the wall or on an electrical connection box. The
controller does not have a communication connection. The fan can be
set to one of three speeds.
RCFM-230TD has change-over function and should be used for
2-pipe systems.

Installation
Place the controller in a location that has a temperature representative for
the room. A suitable location is approx. 1.6 m above floor 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 figure 1). Then use the cutout
that becomes visible in the edge of the bottom plate to open the upper
edge completely (see figure 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!
Disconnection
RCFM-230TD should be connected to a switch or circuit breaker in the
building installation. This switch should be in close proximity to the con-
troller 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
RCFM-230TD has, via a button on the controller, seasonal switching
between heating and cooling (change-over, see below).

Change-over function
RCFM-230TD has a function for change-over via the M button on the
controller. By pressing the M button, you choose whether output DO4
should operate with heating or cooling function. When the controller is
used together with a 3-position actuator, output DO5 is also affected
by the change-over function in accordance with the above.
Operating mode
There are four different operating modes. Switching between these
modes is performed locally.
Comfort: is shown in the display. Heating and cooling have a
smaller neutral zone. Switching between Comfort/Economy and Off is
done via the fan button. Comfort/Economy is selected via the param-
eter list and can be controlled by input DI.
Economy (Standby): "Standby" is shown in the display. The heat-
ing and cooling setpoints are freely adjustable. Factory settings:
heating=15°C, cooling=30°C.
Off: The controller does not heat or cool and the fan stops (unless
mould protection has been selected, in which case the fan will still
run).
Window: is shown in the display, the controller is off and the fan
stops (unless mould protection has been selected, in which case the
fan will still run). The window contact is connected to the DI and must
be configured.
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).
