Additional functions
Relay function
The relay state can be changed by selecting "MENU" and "FUNCTIONS". The relay is preset to the "AUTO" function; the time switch switches at
the programmed times. The following can also be selected: "ALWAYS ON", "ALWAYS OFF" and "EXTRA". If "EXTRA" is selected, the switching status
specified by the program is inverted. The time switch resumes switching according to the programmed switch times after the next switch com
mand.
Holiday program
In holiday program, the holiday period is set with a start and an end date. It can be activated with the "ACTIVE" program item and deactivated with
"PASSIVE". If the holiday program is activated, the time switch does not carry out any programmed switch commands during this time period.
Instead, it remains "ALWAYS OFF" or "ALWAYS ON" during the holiday period, as requested. When the holiday period has ended, the time switch
resumes switching according to the programmed switch times.
1 h test
The "1 h TEST" function can be used for a switching simulation. If "1
After the time has ended, the time switch resumes switching according to the programmed switch times.
PIN code
Input and programming can be locked using a four-digit "PIN CODE". The time switch can be unlocked using the "PIN CODE". The time switch can
also be unlocked using the "RESET" function, which also deletes all settings and programs.
Operating hours counter
This function displays the time for which the relay has been switched on and the date of the last reset. Counting range: 65,535 h.
Contrast adjustment
This function allows the user to adjust the display contrast.
Expert mode*
Expert mode is activated by selecting "OPTIONS" and "EXPERT". After expert mode is activated, the following additional functions can be used:

Control input with switch-off delay
Adjustable switch-o delay via control input. The control input enables an additional switching of the relay, parallel to the switching program.
The switch-o delay can be set from 0 s to 23 h 59 min 59 s. The switch-o delay begins as soon as the voltage is removed from the control input.
Control input "extra"*
Override of switching state via control input. If the "EXTRA" function is activated, the switching state specified by the program is inverted.
The time switch resumes switching according to the programmed switch times after the next switch command. The "EXTRA" function is ended
prematurely if the button is pressed again or if a pulse is received at the control input.
Control input "off"*
Switch o via control input. Activating the "OFF" function causes the time switch to be switched o via the control input. The "OFF" function is
ended if the button is pressed again or if a pulse is received at the control input. The time switch resumes switching on/o according to the
programmed switch times.
Pulse function
Programmable with precision to the second.
Cycle function
Function for cyclical switching. With this function, the time switch is switched on once within a defined time period and for a defined duration.
The cycle time can be set between 2 s and 2 h. The switch-on time can be set between 1 s and 1 h 59 min 59 s.

Random function
If the random function is activated, set switch times are randomly shifted within a range of +/- 15 minutes.
Channel-switching function*
With 2-channel time switches, this function can be activated so that the time switch regularly switches between the outputs assigned to
the channels, in order to protect connected devices (for example lights/lamps) or so that two devices can be used simultaneously.
The channel-switching function is activated by selecting "MENU", "OPTIONS" and "CHANNEL 1<>2". The time switch switches between
the outputs according to whether the menu item "DAILY" (once per day at 12:00 p.m.) or "WEEKLY" (once per week on Sunday at 12:00 p.m.)
is selected.
Mains-synchronous operation
Mains-synchronised clock precision. By activating the "SYNC" function and then "ACTIVE", the quartz-controlled time switch becomes
a synchronous time switch.
