Operation manual

Top: ECO mode is locked providing the presence message
‘occupied’ is showing.
The following parameters can be adapted for heating mode:
Type:
A 2-point or PI controller can be selected as the control type. The PI
controller can also be configured as a pure P controller.
PI controller
The fan is controlled depending on the control deviation
2-point controller
The fan is controlled at maximum speed as soon as:
Room temperature < Heating setpoint - natural convection
Xp
Proportional gain of the PI controller. It describes at which control
deviation the control signal is 100%.
Tn
PI controller reset time. The time that elapses until the I-integral action
component generates the same control amplitude as is immediately
produced by the P gain. This parameter can be disabled so that a pure
P controller is enabled.
The following parameters can be adapted for cooling mode:
Type

PI controller
The fan is controlled depending on the control deviation
2-point controller
The fan is controlled at maximum speed as soon as:
Room temperature > cooling se natural convection
Xp
Proportional gain of the PI controller. It describes at which control
deviation the control signal is 100%.
Tn
PI controller reset time. The time that elapses until the I-proportion
generates the same control amplitude as is immediately produced as
a result of the P-gain. This parameter can be disabled so that a pure
P controller is enabled.
8.4 Inputs
A distinction is made between potential-free inputs and a 230 V input in the
"Inputs" menu. An external sensor can only be used in conjunction with input
1.
There is an option to change the polarity with all inputs.
The following functions can be assigned to the inputs:
•
External sensor (input 1 only)
•
Changeover sensor (input 1 only)
•
Changeover DI
•
Intake sensor (input 1 only)
•
Window contact
