Honeywell SDC manual Reduced operation, Set values RED lowering operation

SDC / DHC Operation

NOTE 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.

4.2.5"Direct Heating Circuit" / "Mixed Heating Circuit 1" / "Mixed 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.

4.2.5.1Reduced operation

During reduced operation, you can select between two operating modes.

Factory setting	ECO
Setting range	ECO, RED
Set values	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.
Application	Building with minimal insulation values and high cooling loss.
