3 Product description
One or more mixed circuits can be connected and controlled via op-
tionally connected mixer modules RoCon M1.
All settings, displays and functions are carried out by the integrated
RoCon BF controller. The display and the operating elements make
operation easy.
A digital room controller (RoCon U1) is optionally available for
greater comfort. It can be used as a remote control and room ther-
mostat.
The controller can be connected to the Internet via the optional gate-
way (RoCon G1). This enables remote control of the GCU compact
by mobile phone (using an app).
Calorific value engineering
Calorific value engineering makes optimum use of the energy con-
tained in the heating gas. The flue gas is cooled down in the boiler –
and in the flue system with ambient air-independent operation in the
concentric flue gas system – to the extent that the temperature is be-
low the dew point. Part of the water vapour generated by the com-
bustion of the gas thus condenses. The condensation heat is fed to
the heating, as opposed to low-temperature boilers, which enables
efficiency rates of more than 100 % (based on the lower heating
value).
