TLC-FCR-T Engineering
Auxiliary functions
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 standby 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:
The external input may be used to automatically determine heating or cooling mode. Connect a qualified passive
sensor to the external input and measure the temperature of the supply media. Heating or cooling mode are activated
once the supply temperature is above or below the respective limits. The limits may be defined in software. Standard
is 16°C (61°F) for cooling and 28°C (83°F) for heating.
Configuration parameters for firmware version 2.0
The TLC-FCR-T can be adapted to wide variety of applications. The adaptation is done with parameters. The
parameters can be changed on the unit without the need of additional equipment.
Identifying the firmware version
The parameters and functionality of controller depend on its firmware revision. It is therefore important to use a
matching product version and parameter set. The firmware version is shown on the large LCD digits when pressing UP
and DOWN buttons for more than 3 seconds simultaneously.
