Power Failure

remain switched off, switch on automatically or return to the operation mode it was in before the power failure.
Frost Protection
The controller will enter frost protection mode if the room temperature drops below 5°C (41°F). All heating outputs will
be fully opened. Frost protection mode will be left once the temperature reaches 10°C (50°F). Frost protection display
will remain until a button is pressed. Frost protection can be enabled/disabled using user parameter UP-09
Clock Operation (Deluxe Version)
TLC-FCR-T contains a real time clock. Up to 16 mode changes (STANDBY, COMFORT, OFF) based on weekdays and
time may be programmed. See chapter operation on how to program switch times.
A blinking clock indicates that the time needs to be set. Time programs will not operate if the time is not defined. See
chapter operation, advanced settings for instructions on how to set the time.
Occupation Sensor, External Heat / Cool change, Auto change over
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. The
external input may as well be configured to change heating and cooling mode by a binary signal or by measuring the
supply temperature.
