Operation  example

:  Schedule  timer  based  on  temperature  set

points.
When setback function (refer to 

"[2] Automatic setback function" on

page 19

) is enabled, the setback operation will have priority over the

scheduled action in the schedule timer.

Operation example

: Schedule timer based on ON/OFF instruction.

When setback function (refer to 

"[2] Automatic setback function" on

page 19

) is enabled, the setback operation will have priority over the

scheduled action in the schedule timer if ON instruction is active. If

OFF  instruction  is  active  this  will  have  priority  over  the  setback

function. At any time the OFF instruction will have the highest priority.

For cooling, no setback function is available.

[1] Settings are not applicable
[2] Automatic setback function

Setback  function  provides  the  possibility  to  lower  the  room

temperature.  The  setback  function  can  for  instance  be  activated

during the night because the temperature demands during night and

day are not the same.

Method 2

Space heating based on ON/OFF instruction

During operation When the schedule timer switches space heating OFF, 

the controller will be switched off (operation LED will stop 

working). 

When pushing 

the 

 button

The schedule timer for space heating will stop (when 

active at that moment) and will start again at the next 

scheduled ON function.

The "last" programmed command overrules the 

"preceding" programmed command and will remain 

active until the "next" programmed command occurs.

Example: imagine the actual time is 17:30 and 

actions are programmed at 13:00, 16:00 and 

19:00. The "last" programmed command 

(16:00) overruled the "previous" programmed 

command (13:00) and will remain active until 

the "next" programmed command (19:00) 

occurs.

So in order to know the actual setting, one should consult 

the last programmed command. It is clear that the "last" 

programmed command may date from the day before. 

Refer to the operation manual.

The controller will be switched off (operation LED will 

stop working).

However the schedule timer icon will stay displayed.

When pushing 

the 

 button

The schedule timer for space heating will be stopped and 

will not start again.

The schedule timer icon will not be displayed anymore.
