Glossary
Room thermostat
A room thermostat continuously measures the room
temperature and compares it with the room temperature
you have set (target room temperature). This allows the
heating system to maintain a constant set temperature
in your room.
In addition, you can enter individual heating times. The
target room temperature and the heating times set by
you control the operation of your boiler, the power of
which is adapted automatically to the respective heat
demand.
Weather compensator
A weather compensator is a controller that controls the
heating flow temperature of the heating system as a
function of the measured outside temperature.
On the weather compensator you can also enter
individual heating times. The outside temperatures
measured and the heating times set control the
operation of the burner, the output of which is adjusted
automatically to the respective heat demand.
vrnetDIALOG Internet communication system
vrnetDIALOG is a service connection to the Internet.
Using vrnetDIALOG your approved heating engineer can
set the heating system in your house from your PC. Fault
diagnosis is also possible remotely via the integrated
DIA system.
vrnetDIALOG can also forward fault messages by fax,
E-mail or SMS to your heating engineer. This allows the
heating engineer to prepare in advance of carrying out
any work, if a repair is required, and to arrive with the
right spare parts on the service date.
If necessary, your heating engineer can also carry out
adjustments on the controller or boiler via vrnetDIALOG
to save unnecessary visits.
