In operating modes HAND and USER, access the next operating function by pressing “MODE”.
Pressing “MODE” will confirm the changed value of the current operating function, i.e., the C 150 will from
now on regulate at the new value.
If you do not want to accept the modification of a value, wait 30 seconds without pressing any
button. The controller reverts to Normal Display automatically without accepting the modifica-
tion.
Use “▲” and “▼” to change the value of the selected operating function or to select between defined
values.
To change numerical values by tenths, press “▲” and “▼” for a very short time. To change
them by whole numbers, press “▲” and “▼” for longer.
In some operating functions, you can read but not change the value (for service and maintenance pur-
poses).
To go back to the Normal display, press “MODE” repeatedly.
If a button for 30 seconds is not pressed after access to an operating function or changing a value, the
controller toggles back to Normal display automatically. If the “MODE” button is not pressed after chang-
ing a value in the displayed operating function, the value reverts to its previous value.
7.2 Operating mode HAND
In Normal display, press but ton “MODE” to toggle to operating mode HAND.
Use “MODE” to successively call up the operating functions.
Use “▲” or “▼” to set the values of the operating functions.
