Technology
The Fan Coil ambient
temperature controller with
display records the current room
temperature and controls the
heating and/or cooling. It also
controls 2 and 4-pipe Fan Coil
units and conventional air-
conditioners.
The ambient temperature
controller is fitted with push-
switches and an LC display
to show the current operating
modes and values.
- Bus voltage
- Current consumption
- KNX
- Temperature sensors
- LCD display
- "ON/OFF" put-switch [ON/OFF
comfort/standby optional]
- "Temperature up" push-switch
- "Temperature down" push-switch
The device is surface-mounted
without a frame and is available
in white and aluminium-silver.
A bus terminal is included for
connection to the KNX. A separate
bus coupling unit is not required.
21...30 V DC over the bus
Type. 10 mA
Bus terminal
Accuracy of temperature sensor +/- 0.3 K
(can be calibrated by parameters)
Sensor type: NTC
The LCD can be lighted if required.
Use the "Lighting Display" parameter. This allows
the LCD lighting to be always on or always off,
or to be lighted after pushing a switch and remain
on for 5 seconds.
If freezing protection is not activated: ambient
temperature control is switched to freezing
protection. "OFF" shown on display. If freezing
protection is activated: ambient temperature control
operates in the mode that it would have had without
being switched off. If the optional ON/Off
comfort/standby operating mode is selected,
the device switches between comfort and standby
when a push-switch is pressed briefly, and switches
OFF if the switch is pressed for a longer period
(> 500 ms).
In night mode the settemperatur can be manipulated
till the next change of operating mode happens.
When a push-switch is pressed, the set temperature
is changed by a configurable value (0.1K / 0.2K /
0.5K / 1K). The display is switched to "Set
Temperature". The actual temperature is displayed
again 5 seconds after the last push-switch
actuation, if this has been configured. If the optional
mode "Enable extended button press for switching
heating/cooling set value" is enabled, the device
switches to the heating set value when the switch
is pressed and held (1s).
