on the variant. The unit serves for
• a fixed installation,
• the registration of the actual temperature (room temperature),
• the setting of the target temperature (comfort temperature)
• the control of the actual temperature by activating actuators
in heating operation (Standard) or heating/cooling operation
(Comfort, Control) in an assigned zone,
• the connection of an external sensor (Control).
Every other use, modification and conversion is expressively forbid-
den and leads to dangers the manufacturer cannot be held liable
for.
