side.
Line Function, parameter
198 Locking of settings
On operating line 198, the settings made on the controller can be locked on the software
side. This means that the settings made can still be called up on the controller, but can-
not be changed.
Locking may comprise:
•
All settings
•
Only the settings required for the district heat parameters
The settings can be changed via the bus.
The procedure is the following:
1. Press buttons and
2. Press buttons, ,
3. Now, operating line 198 appears in the display. The following locking choices are
available:
0 = no locking
1 = all settings are locked
2 = only the settings required for the district heat parameters are locked
(operating lines 101 to 117)
After locking all settings, the following setting elements remain operative:
•
The buttons for selecting the operating lines
•
The Info button
No longer operative will be:
•
The buttons for the readjustment of values
•
The bar for changing the basic setting of the heating curve
•
The setting knob for readjustment of the room temperature
•
The operating mode buttons
•
The manual mode button
The settings required for district heat applications (operating lines 101 to 117) can be
locked by bridging terminals H3–M. This kind of locking has priority over lockings on the
software side. If lockings are made on the hardware side, settings via the bus can no
longer be changed either.
To make the link across terminals H3–M inaccessible, the controller can be sealed to
prevent its removal.
Also refer to section "19. Handling".
