The thermostat is set and programmed via the
menu.
To program some functions, certain values first
need to be set, such as language, time and operating mode.
Electrical equipment must only be installed
and assembled by a qualified electrician in
accordance to the relevant installation standards, guidelines, regulations, directives, safety and accident prevention regulations of
the country.
Failure to comply with these instructions may
result in damage to the device, fire, or other
hazards.
These instructions are an integral component
of the product, and must be retained by the
end user.
A brief button-press will trigger a function or
navigate one step through the menus or
parameters. A button-press > 2 seconds allows
faster forward or backward movement.

The thermostat can be set to heating or cooling
mode.
We reserve the right to make technical and
formal changes to the product in the interest of
technical progress.
DANGER!
-- Heating mode
Touching live parts can result in an electric shock.
An electric shock can be lethal.
Disconnect the connecting cables before working on the device and cover all
live parts in the area!
Installation location
Extraneous heat affects the control accuracy.
To enable optimum room temperature control
using the internal sensor, the installation location
selected should
-- allow free air circulation
-- not be behind curtains, cupboards, shelves,
etc.
-- not be subject to direct sunlight
-- not be subject to draughts
-- not be on outer walls

Adjusting the hysteresis prevents continuous
switching on and off of the thermostat. The setting is made in steps of 0.2 °C.
Recommendation:
- Small hysteresis value for systems with high
inertia torque (e.g. underfloor heating)
- Large hysteresis value for systems with low
inertia torque (e.g. fan convectors)
