Operation

SDC / DHC

 

 

ECO (switch-off operation)

During reduced operation, the direct heating circuit is switched off completely with outside temperatures above the set frost- protection limit. The maximum heat generator temperature is not functional. The heating circuit pump is switched off after a delay to avoid safety deactivation by reheating the heat generator (pump follow-up).

If the outside temperature is or becomes lower than the specified outside temperature frost-protection limit, the controller switches from deactivated (deactivation mode) to lowered lowering operation and controls the heating circuit temperature based on the set lowering curve taking the set minimum heat generator specification into account.

Application Building with high insulation values (full heating protection).

NOTE The mode set here also applies for the ABSENT and RED.

HEATING operating modes.

4.2.5.2Heating system

This parameter refers to the type of the heating system (floor, radiator or convector heating) and can be matched to the exponent of the respective heat distributor. Using its progressive characteristics, the set value determines the curve characteristics of the heating curve of the direct heating circuit and compensates for the losses in output in the low-temperature range with it.

The following settings are recommend depending on the type of heating system:

1,1 Slightly progressive heating curves for floor or other area heating.

1,3 Progressive standard heating curves for all radiator heating with m-values between 1.25 and 1.35.

2 Progressive heating curves for convector and baseboard heating.

>3 Heavily progressive heating curves for general ventilator applications with high starting temperatures.
