Time delay stage II Enabling of stage II (full load stage) is controlled not only by the switching differentials but also by a time delay. In this way, stage

IIremains disabled for the set delay so that stage I will be active longer. This function is only effective during the start-up phase (when there is demand for both stages). When stage I is in base- load operation and stage II in adjustment operation (covering excess heat demand), the latter is switched on immediately when the demand arises.

NOTE In cascade mode, this setting would be superseded by the cascade setting and is therefore not available.

Enabling mode stage II The parameter "Enabling mode full-load stage" allows changing the effect of a time delay stage II setting during the start-up phase below the heat generator minimum temperature limit.

Unlimited enable during start-up relief

Both stages are in unlimited operating during start-up.

Time-out during start-up relief

Stage II is switched on after the set time delay acc. to time delay stage II:

NOTE In cascade mode, this setting would be superseded by the cascade setting and is therefore not available.

Hot-waterThe function "hot-water loading mode stage 1-2" allows defining loading mode of the loading mode for the hot-water heater with 2-stage or 2 x

stage II single-stage heat generators. The following options are available:

•2-stage hot-water circuit loading with delayed enabling of stage II acc. to time delay stage II

•Unlimited 2-stage hot-water circuit loading

•Hot-water loading with stage I only; stage II disabled

NOTE In cascade mode, this setting would be superseded by the cascade setting and is therefore not available.

Outside temperature When the actual outside temperature exceeds the set limit, all disable demand on the heat generator is disabled within a device. The

heating circuits continue operating, but the heat generator will not be switched on. The preset minimum burner running times are
