Manual FCR230

FCR-230
2
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.
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
congured.
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).

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 congured not to be a󰀨ected 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 congured 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, di󰀨erent param-
eter 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 IN-
CREASE 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.
Parameters
The following parameters can be changed in the parameter list.
