Menu item Function
SWITCH-ON DELAY
To set the time (delay timer) before the air volume will switch to PRESET 3 after closing the bathroom switch
contact. (Default: 5 min)
If the bathroom switch is stopped within the set time the unit will act like the bathroom switch has never
been switched on.
SWITCH-OFF DELAY
To set the time (overrun timer) before the air volume will switch to the normal airflow after opening the
bathroom switch contact. (Default: 5 min)
�
FIXED: set a fixed duration which must elapse before the air volum will switch to the normal airflow;
�
MIRROR: set the maximum duration which may elapse before the air volume will switch to the normal
airflow. The unit will stay in PRESET 3 for the same duration as the time the bathroom switch had been
switched on. If the bathroom switch has been switched on longer than the set time, the air volume will
switch to the normal airflow when the timer runs out. (default setting)
POSTHEATER3
To set the PI controller of the post-heater.
�
PROPORTIONAL BAND: set the proportional value of the post-heater; (Default: 2°C)
�
INTEGRAL TIME: set the integral value of the post-heater. (Default: 120s)
0-10V 13 To set the control options of the first 0-10V input.
INPUT AT 0%
To set the required input signal to get 0% output signal from the unit; (Default: 0V)
If positive control is necessary the input at 0% must be lower than the input at 100%:
If negative control is necessary the input at 0% must be higher than the input at 100%.
INPUT AT 100%
To set the required input signal to get 100% output signal from the unit; (Default: 10V)
If positive control is necessary the input at 100% must be higher than the input at 0%:
If negative control is necessary the input at 100% must be lower than the input at 0%.
METHOD
To set the control method for the 0-10V input.
�
STEER: the unit will follow the input signal at all times; (default setting)
�
0..10V: the unit will control the output signal to a set point.
CONTROL SETTINGS
To set the values for the set point control (0..10V).
�
SET POINT: set the set point value of control method; (Default: 5V)
�
PROPORTIONAL BAND: set the proportional value of the control method; (Default:100%)
�
INTEGRAL TIME: set the integral value of the control method. (Default: 300s)
0-10V 23 To set the control options of the second 0-10V input.
INPUT AT 0%
To set the required input signal to get 0% output signal from the unit; (Default: 0V)
If positive control is necessary the input at 0% must be lower than the input at 100%:
If negative control is necessary the input at 0% must be higher than the input at 100%.
INPUT AT 100%
To set the required input signal to get 100% output signal from the unit; (Default: 10V)
If positive control is necessary the input at 100% must be higher than the input at 0%:
If negative control is necessary the input at 100% must be lower than the input at 0%.
METHOD
To set the control method for the 0-10V input.
�
STEER: the unit will follow the input signal at all times; (default setting)
�
0..10V: the unit will control the output signal to a set point.
CONTROL SETTINGS
To set the values for the set point control.
�
SET POINT: set the set point value of control method; (Default: 5V)
�
PROPORTIONAL BAND: set the proportional value of the control method; (Default:100%)
�
INTEGRAL TIME: set the integral value of the control method. (Default: 300s)
0-10V 33 To set the control options of the third 0-10V input.
INPUT AT 0%
To set the required input signal to get 0% output signal from the unit; (Default: 0V)
If positive control is necessary the input at 0% must be lower than the input at 100%:
If negative control is necessary the input at 0% must be higher than the input at 100%.
INPUT AT 100%
To set the required input signal to get 100% output signal from the unit; (Default: 10V)
If positive control is necessary the input at 100% must be higher than the input at 0%:
If negative control is necessary the input at 100% must be lower than the input at 0%.
METHOD
To set the control method for the 0-10V input.
�
STEER: the unit will follow the input signal at all times; (default setting)
�
0..10V: the unit will control the output signal to a set point.
CONTROL SETTINGS
To set the values for the set point control.
�
SET POINT: set the set point value of control method; (Default: 5V)
�
PROPORTIONAL BAND: set the proportional value of the control method; (Default:100%)
�
INTEGRAL TIME: set the integral value of the control method. (Default: 300s)
