The thermostat can be operated in four different variants.
• Room air: The internal temperature sensor detects the room temperature.
The thermostat controls this with the aid of the connected heat load.

• Floor: The floor sensor detects the floor temperature. The thermostat controls this with
the aid of the underfloor heating.
• Dual: The internal temperature sensor monitors the room temperature and controls it
with the help of the connected heating systems. At the same time, the floor sensor monitors the floor temperature and limits this to the predefined maximum temperature value
("max temp").
This variant is particularly recommended for temperature-sensitive parquet and laminate floors.
• PWM: The pulse width modulator (PWM) switches the heating on and off at regular intervals. In PWM mode, you can adjust the desired temperature using the PWM value
(see "Settings the PWM value").
The floor sensor does not work in this operating mode. The room temperature limits are
met.
External temperature reduction
For your safety
¼
DANGER
Risk of serious damage to property and personal injury, e.g. from fire or
electric shock, due to incorrect electrical installation.
Safe electrical installation can only be ensured if the person in question can prove
basic knowledge in the following areas:
• Connecting to installation networks
In all operating modes, you can connect external switches or time controls for temperature
reduction (TR). The internal temperature control is overwritten here. The TR input can also
be used for various functions according to the "PilotWire" specification:

• Connecting several electrical devices
These skills and experience are normally only possessed by skilled professionals
who are trained in the field of electrical installation technology. If these minimum requirements are not met or are disregarded in any way, you will be solely liable for
any damage to property or personal injury.
¼
DANGER
Risk of death from electric shock.
The outputs may carry an electrical current even when the device is switched off.
Always disconnect the fuse in the incoming circuit from the supply before working
on connected loads.

To ensure reliable thermostat operation, note the following when planning the installation
site:
A Minimum installation height: 1.5 m above the floor.
With the programmable touchscreen thermostat with pilot wire (referred to in the following
as the thermostat), you can regulate the room and/or floor temperature. The unit is operated using a touch display.
The thermostat can be connected to electrical underfloor heating systems, radiators or
valve drives which can be switched.
The thermostat has a weekly clock with an individually adjustable program. Alternatively,
you can select one of 3 pre-programmed weekly programs. Various heating modes with
individual temperature setpoints are available: comfort mode, eco mode and frost protection mode.
B Do not install too close to windows, doors or ventilation openings.
C Avoid direct sunlight or direct light from lamps.
Do not install above radiators or other heat sources.
D Do not cover or install behind curtains.
Floor mode or dual mode
E Position at least 1 m from walls or doors.
Install in the middle of the loops of the underfloor heating unit (see drawing).
F Lay the floor sensor in a plastic tube with an inside diameter of 10 mm.

The pulse width modulator (PWM) switches the heating on and
off at regular intervals. In PWM mode, you can adjust the desired temperature using the PWM value. The value is displayed
instead of the temperature setpoint, in the same way (see "Setting the temperature setpoint").
The PWM value specifies the percentage that the heating heats
in a recurring interval of 10 minutes.
Selecting the heating mode

1 Open heating mode selection:
Briefly press the selection key.
The following four heating modes are displayed (from

Setting a weekly program
Editing settings
A weekly program is the schedule for heating phases in eco and comfort modes for the
entire week. Each switching time for a heating phase is defined for individual days or a
group of days.
Three pre-programmed weekly programs are available (see "Possible settings/pre-programmed weekly programs") and you can change these temporarily. Your settings are
only retained until you select another weekly program. In addition, you can create a freely
adjustable weekly program of your own to meet your needs. During commissioning, the
freely adjustable weekly program is selected but no heating phases are stored.
1 Open "Weekly program" menu:
Press and hold the selection key on the standard
display.
The information for a saved heating phase of the active weekly program is shown on the display (here:
