touch display in design System M or System Design.
Getting to know the thermostat
With the programmable universal temperature control unit insert with touch display
(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.
Operating modes
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.
Accessories
• 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.

In all operating modes, you can connect an external switch or time controls for temperature reduction (TR). The internal temperature control is
overwritten here.

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:
Installing the thermostat
• Connecting to installation networks
Installation site of thermostat and floor sensor
• Connecting several electrical devices
• Laying electric cables
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

Once a central plate without a push-button switch plate has been installed, the thermostat push-button switch D is covered and can no longer be actuated.
It is therefore important to make sure that the push-button switch D has been
pressed in (switch position "ON") before install the central plate.

The settings are saved once you confirm the last value.
The thermostat starts with the default settings:
• Comfort heating mode
• Room air operating mode
If a floor sensor is connected, it is detected automatically and the floor operating mode is
selected. The thermostat then switches to the standard display.
|
Also check the following settings:
• Operating mode: Always set the dual operating mode manually. If the sensor
configuration is changed later, the operating mode does not switch automatically
and you also have to set this manually.
• Floor sensor type: Always select the connected floor sensor in the basic settings to ensure correct temperature regulation.
• All the default settings that are automatically selected when the device is
switched on for the first time can be adjusted later on in the "Basic settings"
menu.
Standard display
In the standard display, three different windows appear, changing in rotation every 10 seconds. The current settings and measured values are shown.
The current time is displayed at the top of each window. A red line under the display indicates that the heating is currently active.
Heating the floor or the room to the desired temperature may take several hours.
You should therefore wait a while before increasing the temperature.
Setting the temperature setpoint
Touch Display
1 Switch to the temperature setpoint display:
Press one of the navigation keys.
The setpoint for the room or floor temperature is
shown on the display with green underlining.
2 Lower (-) or raise (+) the setpoint in steps of 0.5 K
using the navigation keys (room air and dual operating modes from 5 °C to 35 °C, floor operating
mode from 5 °C to 50 °C).
The desired setpoint for the room temperature in
comfort mode is shown on the display.
3 Confirm the new setpoint with the selection key.
The standard display opens. If the measured temperature is lower than the new setpoint, the heating turns
on. The display shows red underlining during heating.

Settings the PWM value
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.
Example:
09:01
PWM
50%
0%: heating is permanently off
50%: heating is on for 5 minutes, then off for 5 minutes
100%: heating is permanently on

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.
The information for a saved heating phase of the active weekly program is shown on the display (here:
not heating phase stored).
