Explanation
DIN atmospheric sensor or atmospheric sensor specified in atmospheric sensor list on page 24.
Power supply company control, main release
The controlled outer conductor LF of the power supply company is connected to this terminal - it is
used to start the timing element (not applicable if NW [Neckarwerke] is set for the parameter „ST").
Power supply company control, additional release
Only used if the power supply company provides a second controlled outer conductor in the day-
time charging time, otherwise this terminal remains unused.
Forward/backward switchover:
Operating time control if NW (Neckarwerke) is set for the parameter „ST".
Characteristic switchover (reduction by the value set for the parameter „Ab").
Z1 = Clocked control line (L)
Z2 = Unclocked control line, connected to N; single-wire control possible.
The mains-voltage clock signal is applied at these terminals.
Terminal Z2 is internally connected to terminal N. The clocked outer conductor is applied as a
control signal to terminal Z1.
Mains voltage 200 - 230 V +10 % -15 %, AC 50 Hz.
When connecting the device, make sure that the outer conductor is connected to terminal L.
SH = Charging contactor (see connection diagram on page 3 for SH).
