Grouping for base and peak loads (ANF118-V2.2 specifications)

High quality, expensive condensing boilers are used for the base load, especially with gas systems. During cold months, low- temperature boilers are used for covering peak loads. It is necessary that an activated stage reversal only affect the base load boiler here. The peak-load boilers are excluded from the stage reversal.

Function The configuration defines which peak load heat generator is the first one (all heat generators with addresses greater than or equal to the setting).

The time-based stage reversal (see "Cascading" menu, parameter 05) only affects the connected base-load boiler (smaller address setting).

The first peak-load boiler is not switched on until the base-load boilers are operating at 100%.

If grouping was carried out via the configuration and the peak- load boiler was in demand, a change of the leading group can be activated via a parameter. If this parameter is set to ON, the group of peak-load boilers take over the base load upon demand and the base-load boilers take over adjustment of the flow temperature. Further switching of stages is still only active for the actual base-load boilers.

7.3.12.3.5Special function characteristics

Manual mode The heating circuits of the control device in which manual operation was activated, operate according to the manual function. The set demand value is forwarded to the energy management module of cascade control and adjusted to by the available boiler stages.

Emission measurement This function works as described under "Emission measurement", with the following extensions:

•The effect on heating circuits is extended to all heating circuits of the system.

•Enabling of the heat generators (burner) is initiated at the same devices where emission measurement was activated.
