Description

Room Temperature Controller for Fan Coil A/C

The room temperature controller for the KNX building bus system automatically controls air conditioning with fan coil units. It has touch-sensitive buttons with which the room climate settings can be manually readjusted.
The fan speed (1-3), the setpoint temperature (value, touch buttons +/-) and the mode (automatic on/off, air conditioning on/off) can be set. LEDs show the current settings.
The brightness and switch-off behaviour of the LEDs can be adjusted.
A temperature sensor is integrated in the unit, which can be used for control.
To obtain a mixed value, the unit can receive another measured value via the bus and process it with its value to obtain an overall temperature.
The automatic room climate control includes a PI controller for heating and cooling (one- or two-stage).
This control contains parameters specifically for air conditioning with fan coil systems (systems with fans).
The room temperature controller can also be used as an extension unit, i.e.
it transmits the manual inputs to another control device in the KNX system, which then takes over the control.
Communication objects can be linked in integrated AND and OR logic gates.

Scope of delivery

Push button with mounting
4 screw anchors 4 × 20 mm, 4 flat head screws 3 × 25 mm
KNX plug-in terminal

Installation

The Room Temperature Controller is made for wall mounting.
The device can be mounted directly on plaster or in a device socket according to DIN EN IEC 60670-1/DIN 49073 and other sockets, e.g. Swiss inlet box.
If the device is installed in a socket, this socket must not contain cabling with 230 V.
To avoid falsifying the temperature value, use a wind-proof socket and also seal the inlet pipes against draughts.
When selecting an installation location, ensure that the measurement results are affected as little as possible by external influences. Possible sources of interference include:
- Direct sunlight
- Warming or cooling of the building structure on which the sensor is mounted, e.g. due to sunlight, heating or cold water pipes
- Drafts from windows and doors
- Connection lines and ducts which lead from warmer or colder areas to the sensor
Permanent measurement variations can be corrected in the ETS (offset).

Fig. 6 Open/close device

Remove the front panel from the mounting: Move the front panel a few millimetres upwards to release the lock. The two parts can be easily separated.
Mount the front panel on the mounting:
Place the front panel slightly above the centre position so that it hooks in and slides it down.

Fig. 7, 8 Installation directly on the wall

Remove the red-black KNX plug-in terminal, it is not required.
Connect the bus +/- connecting wires to the spring-loaded terminals on the front panel.
The wires are pushed into the connection openings.
To pull it out, press the spring down, e.g. with a screwdriver.

Fig. 9 Installation on a socket

If there is a cavity behind the device, e.g. when using a socket, you can use the red/black KNX plug-in terminal for connection.

Maintenance

Fingerprints on the glass panel are best removed with a cloth moistened with water or a microfiber cloth.
Do not use an abrasive cleaning agent or aggressive cleansing agents.
