Operating instructions

Preselected Starting Times
The preselected starting time is the time at which the timer switches the heater on automatically.
We recommend that memory locations 1 and 2 be used for presetting starting times within 24 hours
of setting the timer.
Memory location 3 can be used for a starting time within the next 7 days of setting the timer.
Operating Time
The period of time during which the heater is in operation is referred to as operating time.
The heater remains in operation for as long as the operating time has been preset.
Heater operation can be preselected for any time from as little as 1 minute to a maximum of
120 minutes (factory preset is 60 minutes).
Remaining Operating Time
The remaining operating time refers to the period of time the heater still continues to remain in
operation. It can only be changed while heater is in operation.
Setting the Digital Timer
After the power has been connected, all symbols on the digital display will be flashing.
The time of the day and the day of the week must be set.
The Timer can be programmed in that all flashing symbols can be adjusted by means of the
and buttons.
If the buttons are not pressed within 5 seconds, the currently displayed time or function will be
stored.
When the and buttons are pressed for more than 2 seconds, the quick digit advance mode
is activated.
See table 201 on following page for setting reference or full instructions supplied with timer.
