Frost protection will activate if the control temperature sinks below 5°C (41°F).
Operation returns back to normal if the control temperature reaches 10°C (50°F).
Frost protection alarm is displayed as FP in the smaller digits on the LCD display. An
active alarm is indicated by a constant alarm display, once the alarm condition is
removed, the alarm display flashes once per second until acknowledged by the
OPTION key.

If frost protection is active, the unit will switch to high fan speed and set the analog output to full open.
If frost protection is active, the unit will switch to high fan speed and set the analog output to full open.
Frost protection should be disabled for cooling only systems. (Per default on TLR-D41-W01)

The TLR-D5 includes an NTC-based passive temperature sensor. A
sensor of the same type can be connected as alternative control input or
as input for additional functions. The accuracy of the temperature input
is shown in the table to the right. Specified accuracy can only be
guaranteed by using a manufacturer approved temperature sensor. For
best results use Sxx-Tn10 sensors.

Opening the external temperature input will force the unit into the OFF operation
mode. The operation mode cannot be overridden by using the terminal or time
schedules. Connecting the external temperature input to GND returns control of the
operation mode to the terminal and time schedule. This function may be used as
window contact to prevent loss of energy.

Control heat and cool setting of your controller from a central location by switching
a contact to GND. Note: all ground levels of involved controllers must be the same.
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

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

Key Card
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.
