fulfilled. Only when the outside temperature drops to the outside temperature disable level minus 2 K is the heat generator enabled again. If several heat generators are controlled though one device (condensing burners, 2-stage burners), all stages of the device will be disabled.

NOTE If a fault occurs at a heat generator, all outside temperature disables in the system are cancelled.

Base load offset This setting becomes effective only if several heat generators are operated in cascade mode.

Burner stages operating as base load are given a higher setpoint temperature than the modulating stage, which is switched on last. This higher value is composed of the current setpoint temperature plus the set base load offset. If several heat generators are switched though one control device, the setting applies to every heat generator.

Heat generator reset With 2-stage heat generators, the counters for operating hours and burner starts (see Parameter settings 5.4, pg. 81) can be reset separately for stage 1 (ST-1) and stage 2 (ST-2).

Resetting

With the reset indicator flashing (RESET), the reset-ready indicator (SET) will flash when the input button is pressed briefly. A reset will be performed when the input button is pressed for approx. 5 seconds.

After the parameter values are reset, a return to the first parameter in the "Heat Generator" menu occurs.
