Programming internal settings
Push the
SETP.
and
DIFF.
key simultaneously for more than 5 seconds to enter the internal
programming mode.
If P904 is not zero, the controller will ask for a password. The lower display shows ‘code’ and the
required password can be entered in the upper display. The first digit flashes and by pressing the
UP
or
DOWN
key the value of this digit can be changed. If the right value is entered you can confirm it by
pressing the
SETP
key. Now the next digit can be entered. If the last digit is confirmed by the
SETP
key the controller checks the password. If this is correct you enter the parameter-mode. If it is not
correct the controller returns to it’s normal operation.
If parameter P904 is zero, the password check is disabled and the controller goes directly into the
parameter-mode.
In the parameter-mode ‘P1' will appear in the temperature display. The P is flashing. The number
behind the P is the parameter-number which can be changed by pushing the
UP
or
DOWN
key.
In the pulse-counter display the value of the chosen parameter will appear. By pushing the
SETP.
key
simultaneously with the
UP
or
DOWN
key the value can be changed.
When no key is pushed for 30 seconds the controller will leave the programming menu and returns
back to it’s normal operation.
