SDC / DHC Operation
EN2H-0220GE51 R0308 57
If a hot-water thermostat (see 05 parameter = transducer for hot-
water circuit) is used to detect the hot-water temperature, these
parameters are skipped.

Heating Circuit 2" menu
These menus contain all parameters required to program the
heating circuit, except the switch time programs. Max. one direct
heating circuit and two mixed heating circuits (mixed heating
circuit 1 and mixed heating circuit 2) are available as heating
circuits.
The following described heating circuit parameters are available
separately for setting for each heating circuit.

During reduced operation, you can select between two operating
modes.
ECO
ECO, RED
RED (lowering operation)
The heating circuit pump of the direct heating circuit continues
functioning during reduced operation (see 4.2.3.2 Time program,
pg. 52). The flow temperature is determined based on the lowered
room temperature from the associated reduced heating curve.
The set maximum temperature is not undershot.
Building with minimal insulation values and high cooling loss.
