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
Setpoint temperature 10°C
–
30°C
[21°C]
Adjustment of the setpoint
Setpoint offset by 2 Byte object

not active

active
Activation of the setpoint offset via 2
Byte.
Maximum setpoint offset 1,0k

10,0K
[1,0K]
Adjustment of the maximum setpoint
offset
Setpoint offset by 1 Bit object

not active

active
The setpoint offset via 1 Bit object
i reases the setpoi t at re ei i g a
by the adjusted step range and reduces
the setpoi t at re ei i g a the
adjusted step range.
Step range 0,0K
–
1,0K
[0,5K]
Defines the step range fort eh setpoint
offset via 1 Bit object.
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

by temperature and object
Adjustment is only at heating and
cooling systems available!
The automatic switchover switches
automatically, in accordance to the
received temperature and the current
setpoint, between heating and cooling.
At the automatic switchover, the object
5
–
Heating/Cooling switchover, is used
as state object.
Dead zone between heating
and cooling 0,0K
–
10,0K
[2,0K]
The dead zone between heating and
cooling is used for the automatic
switchover between heating and
cooling.
