Fig. 3-3 Wiring of NEA H and NEA HT room controller without use of wiring centre
Note:
The signal for reduced mode has to be potential L (230V-systems) or L1 (24V-systems).
The signal may be generated by a timer or by a switching contact (common or for each separate controller).
In installations with more than one feed-in of operating voltage (e.g. several manifolds and therefore several wiring centres) phase
equality must be observed as soon as there is any electrical connection between the groups of control systems!
