3 Operating Variotime
As the operation of the timer versions
•Variotime Single standard version with 24 hour and/or 7 day program
•Variotime Single special version with 24 hour program only
•Variotime Twin standard version with 24 hour and 7 day program
is widely identical notwithstanding the housing type or the time format these versions will
explicitly be mentioned only if necessary.
The timer is fully operable only after connection to the mains supply completion of the
connections mentioned in section 2.3 and setting of the time of day and the day of the week.
3.1 Initial power up
When connecting Variotime to the mains all display segments appear for approx. 2 seconds.
Subsequently the display flashes “0:00” and the day indicator at day 1 (= Monday). This
indication remains as long as the program timer stays connected to the mains waiting for the
input of time of day and day of the week.
3.1.1 Setting t e day of t e week and
t e time of day
Proceed as follows:
1. Variotime Single: set the right-hand slide switch to  position.
Variotime Twin: set the right-hand slide switch to position RUN and press the buttons h and
m simultaneously for approximately 2 to 3 seconds.
The display stops flashing.
2. Press the day button and set the day of the week as follows:
1 = Monday 3 = Wednesday 5 = Friday 7 = Sunday
2 = Tuesday 4 = Thursday 6 = Saturday
With every pressing action the day indicator advances one day. If the day button is
pressed continuously the day indicator  keeps advancing until button is released again.
24 hour version: not applicable.
3. Set the present time of day via the buttons h and m (24 hour version: buttons plus or
minus).

Subject to change without notice – issued 04-2015 – page 12/20
Keeping the buttons pressed for longer than 2 seconds activates the fast setting mode
which stops when they are released again.
4. Set the right-hand slide switch to RUN position (24 hour program: AUTO position).
The program timer accepts the time setting. The colon in the time display starts to flash.
From now on the time of day will run on accurately to the second.
Variotime Twin: approximately 15 seconds after the setting has been completed the
program timer accepts the time setting. The colon in the time display starts to flash. From
now on the time of day will run on accurately to the second.
Repeat steps 1 to 4 to change the day of the week and/or the time of day.
3.1.2 C annel indication
Variotime Single features one channel that is one relay for controlling a single load. Therefore
the timer display shows “1” by default on the upper right next to the digits indicating the time of
day (see 2.3).
Variotime Twin features a two channels (two relays). Therefore it can control two loads
independently at the same time. The channel which is actively executing an automatic program is
displayed as “1” or “2” on the upper right next to the digits indicating the time of day (see 2.3). If
both channels are active they are being displayed side by side as “12”.
3.1.3 Power failure
In case of a power failure Variotime will retain the time of day and the day of the week for a
minimum of 5 minutes. The longer the program timer has been connected to the mains and has
been able to charge prior to the failure the longer is its buffer time. The automatic program
remains stored in the memory but cannot be executed.
If the power returns within the buffer time Variotime will keep on running normally and will
resume the automatic switching program.
If the power failure exceeds the buffer time the last stored automatic program remains in the
memory however Variotime loses the time of day and the day of the week. When the power
returns these have to be set first before the program timer can resume the automatic switching
program.

3. Reactivate both channels by setting the left-hand slide switch to position AUTO.
The timer resumes the automatic program and displays the present status accordingly.
Change a current setting by terminating first and resetting again.
3.2.3 Automatic mode
In the automatic mode the appliance in which Variotime is installed is being controlled according
to the inputted program. The display shows the present status. During normal program execution
the left-hand slide switch is in position AUTO and the right-hand slide switch is in position RUN (24
hour program: AUTO).
3.3 Setting t e switc ing points
Generally Variotime can be programmed with 16 switching points per channel (8 ON and 8 OFF)
spread over 24 hours. The switching points are numbered as follows:
•switching points with uneven numbers (1 3 5 7 9 11 13 and 15) are ON points. They
are indicated by the light bulb symbol in the display.
•switching points with even numbers (2 4 6 8 10 12 14 and 16) are OFF points. The
light bulb symbol is off.
In order to avoid errors in the program logic the switching points should always be programmed
in pairs that is always an ON point and subsequently the corresponding OFF point.
The 112 switchings per week result from the possibility to assign identical switching points to
several days of the week. Diehl Controls advises to set up a time schedule first as a basis to input
a complex block program for several days. For setting use the day button with the following
combinations:
•single days of the week
1 = Monday 2 = Tuesday 3 = Wednesday 4 = Thursday 5 = Friday
6 = Saturday 7 = Sunday
•day block 12345 = daily from Mondays through to Fridays
•day block 67 = daily on Saturdays and Sundays

•day block 123456 = daily from Mondays through to Saturdays
•day block 1234567 = daily from Mondays through to Sundays (7 days a week)
Each pressing of the day button advances the day indicator by one day until day 7 is reached.
Then the day blocks are called up one after the other resuming again with the single days at day
1.
In the 24 hour version the 16 switching points are spread over 24 hours only.
In Variotime Twin the full 16 switching points are available for both channels independently.
The shortest interval between the switching points is 1 minute.
Proceed as follows:
1. Variotime Single: set the right-hand slide switch to position .
Variotime Twin: set the right-hand slide switch to position P1 (channel 1) or P2 (channel
2). Both channels have to be programmed individually.
The display flashes “0:00” on the top right the (selected) channel is indicated on the
bottom right “I” is indicated (switching point 1 ON). The light bulb symbol appears.
2. Set the time for the switch on point using the buttons h and m then assign it to the days
of the week by pressing the day button. The order of the settings is not important.
3. Pressing the button  advances Variotime to the next switching point 2 (OFF).
The display flashes “0:00” on the top right the (selected) channel is indicated on the
bottom right “2” is indicated (switching point 2 OFF).
4. Set the time for the switch poff point using the buttons h and m then assign it to the days
of the week by pressing the day button. The order of the settings is not important.
5. Pressing the button  advances Variotime to the next switching point 3 (ON).
Repeat steps 1 to 4 until all times for switching on and off have been programmed (16
maximum) in the same manner.
6. Reset the right-hand slide switch to the position RUN (24 hour version: AUTO).
The display reverts to the present time of day and day of the week. Supposing that the left-hand
slide switch is in position AUTO Variotime immediately executes the program set for the present
time and indicates the status as described above. From now on Variotime will follow the inputted
automatic program day for day and week for week until the settings are changed.
To check or change switching points proceed as follows:
7. Set the right-hand slide switch to position  (Variotime Twin: P1 or P2).
8. Select the individual switching points by pressing the button  repeatedly.

Follow this procedure to check of change switching points any time.
9. Having finished set the right-hand slide switch back to position RUN (24 hour program:
AUTO).
To cancel individual switching points proceed as follows:
10. Set the right-hand slide switch to position  (Variotime Twin: P1 orr P2).
11. Press button  repeatedly until the relevant switch on point is selected.
12. Now press the skip button and the button  simultaneously for approximately 2 or 3
seconds. The display flashes „0:00“ showing the switching point has been canceled.
13. Proceed likewise to cancel the linked switch off point to avoid logic errors.
14. Set the right-hand slide switch back to position RUN (24 hour program: AUTO).
To cancel the entire automatic program use the reset function (see 3.4).
3.4 Reset function
The reset function is recommended for extensive changes in the automatic program. It cancels the
previous input entirely and resets the timer into initial power up status. So a new program can be
created without having to access the individual switching points.
In order to avoid resetting the timer inadvertendly the button R is recessed and has to be pressed

Example:
Variotime is in ON mode that is according to the automatic program the appliance in which the
timer is installed is presently switched on. Pressing the skip button immediately switches the
appliance off remaining so until the skip button is either pressed again or the next switching
point is reached. This switching point is being executed again according to the automatic program.
Staying with the example the appliance remains switched off until the next switch on point is
reached.
Vice versa a switched off appliance is switched on by pressing the skip button . When
reaching the next switching point the skip function is canceled however the appliance remains on
as a switch off point is always followed by a switch on point.

1. Press the skip button once. The appliance changes into the opposite operation mode.
The skip symbol appears in the display so does the light bulb symbol if the
appliance was off before or it disappears if the appliance was on before.

appears in the display so does the light bulb symbol if the load was off before or it
disappears if the load was on before.
This operation mode continues until the next switching point is reached which will be executed
according to the program. The skip symbol disappears.

symbol disappears and Variotime reverts to the current operation mode according to its
