4. Operation

Operating modes and status LED

The regulator compares the actual room temperature to the preset

reference temperature and adjusts heating and cooling installations in

accordance with the respective energy requirements. The temperature

reference value depends on the respective operating mode and can be

varied with the adjusting wheel (Fig. 1, 2). The operating modes and the

current regulator status are indicated by means of status LEDs (Fig. 1, 3)

Setting the mode of operation

Control elements for setting the operating mode are installed, e.g. touch

sensors, control panels, etc.

Activate the desired mode of operation with the corresponding control

element.

The new operating mode is indicated by means of status LEDs (Fig. 1,

3).

The reference temperature for the room is set in accordance with the

selected operating mode.

Changing the room temperature

To increase the reference temperature:

turn the adjusting wheel clockwise.

To lower the reference temperature: turn the adjusting wheel counter-

clockwise.

Activating the comfort prolongation

It is desired to prolong the comfort mode for a certain time beyond the

preset automatic switch-over of the operating mode. This can be ensured

by the comfort prolongation. The time for which the comfort prolongation

mode can be prolonged is limited.

LThe comfort prolongation can also be activated

Lautomatically, e.g. from a presence detector.

LInformation for qualified electricians

LDANGER!

Electric shock in case of accidental contact

be fatal.

Before working on the device, disconnect

the supply voltage and cover up live parts

in the working environment.

4.1. Fitting and electrical connection

Fitting and connecting the device

The device is composed of a terminal insert with supporting ring and

electronic attachment module (Fig. 2).

Do not use the regulator together with other electrical devices in the

same combination since the heat produced by these devices may

influence the temperature measurement of the regulator.

Do not use the regulator in the vicinity of heat sources such as electric

ranges, refrigerators, draughts of air or insolation to avoid wrong

temperature measurements.

The optimal fitting height is about 1.5 m.

Install the device in a flush-mounting box as per DIN 49073 or in a

surface-mounting box.

Recommendation: Use the deep type of box.

Detach the electronic attachment module (Fig.2, 6) from the terminal

insert (Fig.2, 4)..

Connect the bus line to the terminal insert using the connecting

terminals (Fig.3, 10).

KNX Stetigregler

Art.-Nr.: ..2178..

Install the terminal insert (Fig. 2, 4) in the flush-mounting box. Pay

attention to the lettering OBEN / TOP.The bus connection (Fig.3, 10)

must be at the bottom.

Place the design frame (Fig.2, 5) on the terminal insert (Fig. 2, 4)..

Install the electronic attachment module in the correct position on the

terminal insert.

Withdraw the adjusting wheel (Fig. 2, 2).

Fix the electronic attachment module with the safety screw (Fig.2, 7)..

Put the adjusting wheel (Fig. 2, 2) back in place on the module.

4.2. Commissioning

Physical address and application software

Use the commissioning software from ETS2 version 1.2 onwards..

Withdraw the adjusting wheel (Fig. 2, 2).

Press the programming button (Fig. 2, 9)

The programming LED (Fig. 2, 8) is illuminated.

Assign the physical address.

The programming LED (Fig. 2, 8) is off.
