Fig. 3-2 Wiring of NEA H and NEA HT room controllers to NEA H 230 V / 24 V wiring centre
Comment:
The connection of the reduced mode signal (clock symbol) is optional. The NEA wiring centre provides 2 time switch signals (A and B).
Each controller can be assigned to one of the time switch signals.
The time switch signals of the wiring centre are generated by NEA timer (2-channel weekly timer).
Triggering of reduced mode (Energy saving):
NEA H:
The external time switch signal is only valid, when the operating mode "time switch programme" is activated by the control buttons on the
controller.
When the controller is in normal operating mode or in reduced operating mode, the external signal is void.
NEA HT:
The same for NEA H room controller is valid, but in operating mode "time switch programme" the mode (normal/reduced) defined by the
internal time switch programme is overwritten by the external signal (Force of reduced mode).
