7 .9 "Valve Control" parameter (continued)
7 .9 .3 "A – Function" parameter (continued)
Purge cycle in weeks [1…12]
1…
*6
…12
If the “
Automatic valve purge
” parameter is selected “
yes
”, this
parameter is visible. The purge cycle is started automatically after
initialization of the actuator. If the valve isn’t actuated for a period of
the adjusted time, then the actuator open the corresponding valve for
a period of 5 minute.
7 .9 .4 "A – Limit" parameter
Min . limit of control value % [0…100]
*0
…100
The parameter adjust the minimum limit of the control value.
Min . limit of valve position % [0…100]
*0
…100
The parameter adjust the minimum limit of the valve position.
Max . limit of control value % [0…100]
*0
…100
The parameter adjust the maximum limit of the control value.
Max . limit of valve position % [0…100]
*0
…100
The parameter adjust the minimum limit of the valve position.

7 .10 "Fan Coil" parameter
7 .10 .1 "Fan" parameter
Select valve with working
*valve A/B
valve C/D
valve E/F
valve G/H
valve I/J
This parameter is used to select valve channel working with automatic
mode. Selected valve channel control value input object also used for
fan level in the automatic mode.
Number of fan levels
1…
*3
The fan level can be selected to the specific fan coil application
required by means of parameter configurations. Thus, initially the
number of fan levels required for the connected devices can be
defined. The number of fan levels can be specified separately for each
fan coil channel.
Controlling the fan levels
*only one fan output switches
fan outputs switch hierarchically
The change-over principle:
When a fan is switched on, there is
always only one fan level output active "
ON
". If the active fan level is
changed, the fan coil actuator first switches the previously switched-
on fan level off ("
OFF
" state), and only after that switches the other
output on.
The level principle:
When a fan is switched on, several outputs are
switched on, depending on the active fan level. When the fan level is
increased, the adjacent output with the next higher output number is
also switched on; the lower outputs remain switched on.
Fan operation mode
*changeover switch
step switch
This parameter can be used to select the properties of fan. Please look
the fan technical data.
• Set the parameter to “
changeover switch
”:
In this mode delay between two fan speeds. This delay time can be
configured via delay between fan speed switching in ms [50…5000]
parameter.
• Set the parameter to “
step switch
”:
In this mode current fan speed must be switched on for a least time
before the new fan speed is switched on.
Delay between fan speed switching in ms
[50…5000]
50…
*500
…5000
If the Fan operation mode parameter is selected “
changeover switch
”,
this parameter is visible. This parameter is used to configure the fan
delay time. This time is using between the fan speed switching.

Using this parameter, the fan reaction can be set after bus voltage
failure is set.
