1.1.1 Sensor calibration: DIP switch 1

Set the DIP switch to ON and press the DIP switch reset button:

The display shows CAL. The room temperature currently acquired

blinks.

Press

or to make a recalibration of max. ± 5 °C. To save

the entry, set the DIP switch to OFF and press the DIP switch reset

button (also refer to Fig.

1.1.2 Setpoint limitation: DIP switch 2

DIP switch ON: Setpoint limitation 16…35 °C

DIP switch OFF: Setpoint limitation 3…35 °C

(factory setting)

Save the entry by pressing the DIP switch reset button.

1.1.3 Temperature display in °C or °F:

DIP switch 3

DIP switch ON: Temperature display in °C

DIP switch OFF: Temperature display in °C

(factory setting)

Save the entry by pressing the DIP switch reset button

(also refer to Fig.

)

1.1.4 DIP switches 4 and 5

Optimum start control shifts switch on point P.1 such that the adjusted

setpoint will be reached at the required point in time. The setting

depends on the type of controlled system, that is, on heat transmission

(piping network, radiators), building dynamics (building mass,

insulation) and heat output (boiler output, flow temperature)

(also refer to graph in Fig.

/ 1.1.6).

DIP switch 4 ON and 5 ON:

1 h/°C For slow controlled systems

DIP switch 4 ON and 5 OFF:

¼ h/°C For fast controlled systems

DIP switch 4 OFF and 5 ON:

½ h/°C For medium controlled systems

DIP switch 4 OFF and 5 OFF:

OFF Off, no impact (factory setting)

Save the entry by pressing the DIP switch reset button.

1.1.5 Integral action time (volume adaptation):

DIP switches 6 and 7

DIP switch 6 ON and 7 ON:

Normally sized controlled systems, refer to factory setting.

DIP switch 6 ON and 7 OFF:

Fast controlled systems:

For small rooms, light radiators (plate radiators),

well insulated buildings or fan coils.

DIP switch 6 OFF and 7 ON:

Slow controlled systems:

For large rooms, heavy radiators (cast iron radiators),

poorly insulated buildings, or great building masses.

DIP switch 6 OFF and 7 OFF (factory setting):

Normally sized controlled systems:

For normal-size rooms, normally sized

radiators (steel tube radiators) and buildings with

average insulation.

Save the entry by pressing the DIP switch reset button.

1.1.6 Control gain (adaptation of heat output): DIP

switches 8 and 9

DIP switch 8 ON and 9 ON:

Normally sized heat output, refer to factory setting. DIP DIP

switch 8 ON and 9 OFF:

Undersized heat output:

For low boiler / flow temperatures, too small radiators

(surface) and too small volumetric flow

(nominal valve size).

DIP switch 8 OFF and 9 ON:

Oversized heat output:

For high boiler / flow temperatures, oversized radiators

(surface) and oversized volumetric flow (nominal

valve size).

DIP switch 8 OFF and 9 OFF (factory setting):

Normally sized heat output.

Save the entry by pressing the DIP switch reset button.

1.1.7 Radio clock: DIP switch 10

Can only be used with REV..DC (with integrated DCF77 receiver for

time signal from Frankfurt)!

DIP switch ON: Clock runs on built-in quartz

DIP switch OFF:

Time signal DCF77 from Frankfurt

Save the entry by pressing the DIP switch reset button

(also refer to Fig.

1.1.8 DIP switch reset

When changing one or several DIP switch positions, press the DIP

switch reset button to make a DIP switch reset.

Otherwise, the previous settings will be maintained!

2 Accessing the expert level

Move the selector slider to the RUN position and press simultaneously

and for 3 seconds, then release the buttons and, within 3 seconds,

press simultaneously and for 3 seconds, release and keep depressed for another 3 seconds. This enables you to access the expert

level for making the settings on that level.
