Heat source sensor (storage tank) for the RMS
function
Heat sink sensor (unmixed return of the heating
circuit) for the RMS function
Target temperature / maximum temperature
sensor (mixed return of the heating circuit) for
the RMS function
Switch-on temperature difference for the
COSMO RMS (activation of the heating circuit
return admixing)
Switch-off difference for COSMO RMS
(Deactivation of heating return admixing)
Set temperature difference (increase of the
heating return temperature) for the COSMO
RMS
Recommendation:
15.0 - 20.0 K for radiator heating systems
8.0 - 10.0 K for radiant floor heating systems
Maximum return temperature of the heating
circuit to the heat generator (Please observe
the instructions of the manufacturer of the heat
generator.)
Recommendation:
75 °C for radiator heating systems and
low-temperature boilers
60 °C for radiator heating systems and
condensing boilers
45 °C for radiant floor heating systems
Setting time of the mixing valve
(duration of the mixing valve control per control
impulse)
External = The controller sets the parameters
on the basis of the previously mentioned
parameters and sets this way the desired return
temperature to the heat generator.
You may adjust the opening position of the
mixing valve for detection of the heating
operation.
Mixing valve runtime time
(from entirely open to entirely closed)
(see the technical data of the mixing valve
integrated in the RMS)
Time at which the RMS mixing valve adjusts
itself every 24 hours
(During this period, the mixing valve is
completely closed)
The function can be deactivated here tempo-
rarily.
