The following table shows the available settings:
ETS-text
Dynamic range
[default value]
comment
Release time to automatic
mode 0-1440
[0]
Defines the time which starts after
switching into the direct mode. When
this time is elapsed, the FanCoil
switches back into the automatic mode.
Monitoring time of control
value 0-360min
[0 min]
Defines the time periods in which the
actuator must receive a valid control
value. If no control value is received, a
control value failure is released and the
FanCoil switches into the step for a
FanCoil failure..
Step at failure of control value

Off

Step 1

Step 2

Step 3
Step at a control value failure
Threshold for fan step 1
0-100%
[5%]
Defines from which value the FanCoil
switches into step 1.
Threshold for fan step 2
0-100%
[50%]
Defines from which value the FanCoil
switches into step 2.
Threshold for fan step 3
0-100%
[80%]
Defines from which value the FanCoil
switches into step 3.
Hysteresis 0-10%
[2%]
Defines the hysteresis for switching off
the current FanCoil step. Point of
switching off = Fan Step - Hysteresis
Dead time at switching
heating/cooling 0
–
1000s
[60s]
Defines the pause between
heating/cooling switchover. During this
dead time, the FanCoil is witched off
and both valves are closed.
Switchover between heating
and cooling

manually by object

automatically by control
value
Setting is only at 4-Pipe systems
available!
At the automatic switchover, the
heating mode is active when the control
value for heating has a value >0%. I the
control value for heating has a control
value =0% and the control value for
cooling has a control value >0%, the
cooling mode will be switched on. At
the automatic switchover, the object 5

Heating/Cooling Switchover works as
state object.
