RCF-230D
The display is handled using the buttons on the
thermostat:
On/Off button
INCREASE temperature setpoint
DECREASE temperature setpoint
Fan speed
On/Off button
By pressing the On/Off button, RCF-230D will switch
between Off mode and Comfort/Economy mode.
Setpoint buttons
The INCREASE and DECREASE buttons are used for
changing the setpoint value. What is shown in the display
can be configured via the parameter list. There are four
alternatives:
1. The actual value is shown, or, when the setpoint
has been changed via the INCREASE and
DECREASE buttons, the setpoint value is
shown in the display (together with the setpoint
(thermometer) symbol).
2. The actual value is shown, or, when the setpoint
has been changed via the INCREASE and
DECREASE buttons, the setpoint adjustment
value is shown in the display (together with the
setpoint (thermometer) symbol).
3. The setpoint value is shown (factory setting).
4. The setpoint adjustment is shown.
When the setpoint adjustment is displayed (alternatives 2
and 4), the basic setpoint is 22°C.
The minimum limitation of the setpoint value is settable
5...22°C and the maximum limitation is settable
22...35°C.
Fan button
By pressing the fan button, you set the fan speed to Low,
Medium, High and Auto.
Configuration via the parameter list
The factory settings are changed in the parameter list
shown in the display using the buttons on the thermostat.
The parameter values are changed with the INCREASE
and DECREASE buttons and changes are confirmed with
the On/Off button.
The parameter list can be found in the instruction for
RCF-230D.
Control principles
Control principle at cooling function
When the controller is set to cooling, the output is
activated when the temperature rises above the setpoint
by the set hysteresis. The output opens when the setpoint
value is reached.
Control principle at heating function
When the controller is set to heating, the output is
activated when the temperature falls below the setpoint
by the set hysteresis. The output opens when the setpoint
value is reached.
