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 weather-
compensated heating circuits. One heating circuit can
be controlled via the internal control functions and the
others via an additional external module RESOL HKM2
sold separately.
The TFlow-value indicates the measured actual flow tem-
perature of the heating circuit.
The Temperature-outdoor-value indicates the measured
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, not included
in delivery scope) and the controller day correction or
night correction are added.
Flow set temperature = heating curve tempe re-
mote c (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 set to the maximum flow temperature.
The internal heating circuit is activated in this menu.

Adjustment channel for night correction (night set back)
of the heating circuit. For the night correction function,
time frames (see below) can be adjusted. Within these
time frames, the set flow temperature of the curve will be
decreased (set back) by the adjusted temperature value.
Adjustment channel for the day correction function of the
heating circuit. The day correction function is always active
except during the 3 time frames of the night correction
function. The flow set temperature of the curve will be de-
creased or increased by the adjusted temperature value.
Night correction:
Arrangement/Heat. circuit/hc/night corr.
adjustment range: -40 ... +50 °Ra
factory setting: -10 °Ra
Day correction:
Arrangement/Heat. circuit/hc/day corr.
adjustment range: -10 ... +80 °Ra
factory setting: 10 °Ra
Adjustment channel for the admissible maximum flow
temperature of the heating circuit. If the maximum flow
temperature is exceeded, the heating circuit will be swit-
ched off (the mixing valve will close).
Maximum flow temperature:
Arrangement/Heat. circuit/hc/Tflowmax
adjustment range: 50 ... 200 °F
factory setting: 120 °F
