With this setting, short switching times (1s to 300s, accuracy 1s) can be realized. The
switching time is set by entering the switch-on time and duration.
Automatic dosing
As many Dosings per day will take place as it has been set before under Switching cycles per
day. The time points of the dosings are calculated automatically (they are spread evenly
throughout the day). The switching duration is calculated automatically on the basis of the
Flow rate of the pump and the Rate per dosing (see below).
Manual dosing
As many Dosings per day will take place as it has been set before under Switching cycles per
day. The time points of the dosings can be defined explicitly afterwards. The switching
duration is calculated automatically on the basis of the Flow rate of the pump and the Rate per
dosing (see below).
Event start
The timer initiates an operation such as e.g. A water change, see also under ->Level. Enter the
start time only.
Cyclic
This mode allows very special switching sequences. Please note that this mode can only be
selected and set via our PC program GCC (GHL Control Center)!
In this mode, the timer is switched on and off alternately, always after a certain waiting time
has elapsed.
The wait time after which is switched on is determined by random generator within the limits
of the minimum waiting time and maximum waiting time. If the waiting time should always be
the same, enter the same value for both times. The waiting time after which is switched off is
also determined by a minimum waiting time and a maximum waiting time.
One cycle consists of 1 to 4 pairs of switch-on and switch-off waiting times. After the last
switch-off of the cycle, the cycle starts from the beginning. All waiting times are adjustable in
the range from 1 s to 65535 s.
Example for a cycle with 2 switch-ons and switch-offs:
After 10 to 20 seconds is switched on
After 60 seconds is switched off
After 300 to 1000 seconds is switched on
