Redundant Heat Generator

A redundant heat generator is not part of the normal sequence, but used only as a back-up for special conditions.

This heat generator will be added to the sequence, if all the heat generators of the sequence are switched on at their maximum capacities and the strategy requests another heat generator and one of the following conditions becomes true:


To define the maximum number of heat generators in the normal sequence, set the parameter CFG-02 to one of the possible values 0 or 1.

If the parameter value CFG-02 = 1, the last heat generator will be the redundant one and never be part of the normal sequence.

If the parameter CFG-02 is the default value “0”, all the heat generators will all be part of the sequence.


Redundant heat generators will never considered in the cyclic changeover.
