230v HVAC ECO Modbus FCU Touch Screen Hotel Room Temperature Thermostat with NTC Sensor

Operating mode configuration
1) Occupancy detection (keycard switch contact) based climate control: In this operating mode, operation is
enabled when the keycard switch input switches to the closed position. When this happens, the keypads are
enabled and the user may start the operation at any time. When the keycard switch input is open, the device
pushbuttons remain blocked.

When the card is pulled out, the climate control system switches to Off or to the Economy mode, depending on
the configuration of parameter P15. There is a programmable delay for the action to take place after the card has
been pulled out. Parameter P14 is used to set the delay time.

2) Climate control + lighting (Lighting auxiliary):
In this operating mode, the controller may be switched on or off at any time through the front panel pushbuttons,
since there is no keycard switch contact available to block the device. The keycard switch contact is in this case
configured to operate as a lighting contact, which acts on the AUX output every time the input changes its state
(refer to installation diagrams). This operating mode is only possible on 2 pipe systems.
