Internal heating circuit control:
Arrangement/heat. circuit/Options/hc
selection: „Yes“, „No“
factory setting: „No“
4.2.1 Heating circuits:
The controller can control up to 4 independent wea-
ther-compensated heating circuits. One heating circuit
can be controlled via the internal control functions and
the others via an additional external module COSMO
HKM each.
The TFlow-value indicates the measured actual flow
temperature of the heating circuit.
The Temperature-outdoor-value indicates the mea-
sured outdoor temperature depending on wheather
conditions.
The flow set temperature is calculated from the
measured outdoor temperature and the heating curve.
Onto this, the dial setting of the remote control (RTA11-
M) and the controller day correction or night correction
are added.
Flow set temperature = heating curve temperature +
remote control + (day correction or night correction).
If the calculated flow set temperature is higher than
the adjusted maximum flow temperature, the flow set
temperature will be equated with the maximum flow
temperature.
The internal heating circuit is activated in this menu.

Each timer function provides up to 21 time frames (3
for each day). The relay allocated to the function block
is activated as long as the time frame (t(x)on ... t(x)off)
is open. The switching conditions of all other activated
functions of the function block have to be fulfilled as
well.
