Remote Enable:
The unit may be remote controlled by using the external input as open contact input. Opening the binary input will
force the unit into the OFF operation mode. The operation mode cannot be overridden by using the terminal or time
schedules. Activating the digital input returns control of the operation mode to the terminal and time schedule.
Occupation Sensor
Remotely control comfort and economy mode for example with an occupation sensor or key switch. If the binary input
is deactivated for a selectable time the unit will change to stand by mode. For a key switch, set delay time to 0.
Heat / Cool change:
Control heat and cool setting of your controller from a central location. Choose if heat or cool is to be active when
contact is open.
Auto Changeover with supply media temperature sensor:
The external input may be used to automatically determine heating or cooling mode by measuring the temperature of
the supply media. Connect a qualified passive sensor to the external input. Heating mode is activated once the supply
temperature is above the heating limit. Cooling is activated when the supply temperature is below the cooling limit.
The limits may be defined in software. Standard is 16°C (61°F) for cooling and 28°C (83°F) for heating.
Auto Changeover with outside temperature sensor:
The external input may be used to automatically determine heating or cooling mode by measuring the outdoor
temperature. Connect a qualified passive sensor to the external input. Heating mode is activated once the supply
temperature is below the heating limit. Cooling is activated when the supply temperature is above the cooling limit.
The limits may be defined in software. Standard is 16°C (61°F) for heating and 28°C (83°F) for cooling.
Key Card:
The external input is connected to a key card in hotels. If input is closed the unit is in normal operation with the
setpoint being chosen by the end user. When input is opened, the unit will change to economy mode. A preset setpoint
defined with FC12 for heating and FC13 for cooling is used instead of the selected setpoint. The setpoint shift feature
is disabled.
