unction Description - Buttons
On the touch surface, there are adjustment options for setpoint and fan speed regulation.
The fan speed can be set by the
Buttons UP (1) and DOWN (2). 3
seconds without any interaction,
the display returns back to main
screen. While pressing of these
buttons, the white LED of the
Power-button (5) lights up for
visual feedback.
With power-button (5), the device can be set in standby mode by pressing the button (if keycard-switch is NOT used). If the button
is used as a occupancy button, the button must be pressed for at least 3s, in all other cases, a short actuation is sufficient. In
standby mode, the display and all outputs are switched off (controller deactivated). The frost and heat protection monitoring remains
active.
Modbus registers can still be read (e.g. room temperature).
unction Description – Controller/Fan stages
F
Room temperature controls for heating and cooling can be individually adjusted and can be achieved as required using a "2-
point/3-point controller" or a continuous "PI controller".
Fan stages
In automatic mode the fan speed is linked to the controller. The assignment of the fan stage to the control (heating / cooling, only
heating, only cooling) is freely selectable. To ensure that the fan motor starts reliably, a period of time can be configured in which
the fan starts with maximal value. Using one or more time channels, the fan control have to be set per timechannel and per period.
Via the touch surface the user has the option to override the settings of the device every time. When the next time channel starts,
the fan speed is set to the configured value. The fan is set to automatic mode when the user changes the occupancy state
(occupied↔unoccupied).
EC Fan automatic mode
The 0..10 V (0..100%) control of the fan is proportional to the calculated manipulated variable of the PI controller.
