10.1 Function description
C01- Enable buzzer:
Allows enabling or disabling the internal buzzer for alarm signaling and sensor error conditions.
C02 - Time for functions lock:
For safety reasons the controller has a feature to allow locking functions. When this configuration is
active, the setpoint and other parameters are protected from undue changes. However, these
parameters can be viewed.
In this state, when trying to change these values, a[LOC,]message will be displayed.
9. AJUSTING THE DESIRED TEMPERATURE
Hold down the / key for 2 seconds to enter the setpoint adjustment menu. The message [SP,,]
will be shown in the display, followed by the value to adjust the normal setpoint. Use the >or< keys to
change the value and press the/key to confirm. The message [SP-e] will be displayed to indicate
the economy setpoint adjustment. Again, use the >or< keys to change the value and press
the/key to confirm. Finally the indication [----] is signaled to conclude the configuration. The
setpoints may also be adjusted individually in the quick access menu.
To lock the functions you need first to adjust the parameter “[,C02]- Time for function lock" with a value
greater than 14 (any value below 15 will cause [no,,]to be displayed and it means that function lock is not
allowed). Using the ;key (short touch), select the function lock function and then press/(short touch). After
that, keep the>key pressed until [LOC,][On,,]is displayed.
To unlock, turn the controller off and then turn it on again with the > key pressed. Keep the key pressed until the
[LOC,][OFF,] message indicates the unlocking (10 seconds).
