Three seconds after applying voltage to the
controller the actual temperature of the room
sensor is being displayed.
Calling up Parameters
Upon pressing the "Programming" key one of
the parameters numbers is displayed which are
listed on page 4 of this manual. Using the
ñ
or
ò
key, you can select any other parameter.
Upon pressing "P" again, the value of the selec-
ted parameter is displayed.
Editing Parameters
A displayed value can be edited by use of the
ñ
and
ò
keys. Pressing "P" again brings you back
to the parameter list and loads the edited value
into the controller.
Unlock Keys
To prevent un-authorized persons from editing
parameter values, there is a locking function
which allows only the setpoint to be changed at
any time. All other parameters must be unlok-
ked beforehand. This means that at parameter
P33 a certain value is to be set (---88---) :
- Press "P",
- Use "
ñ
" to select parameter P33
- Press "P" again
- Use "
ñ
" to set value to --88--
- Press "P" again to select parameter to edit.
If no key is hit for about one minute, the access
code is cancelled and the editing function is
locked automatically.
