TLR-D5 Engineering Manual
Mechanical design and installation
The unit consists of two parts: The base unit and the terminal.
Installation base
The housing of the TLR base unit is a compact enclosure. The controller may be mounted in any orientation by surface
mounting on a wall or in a cabinet with two screws or on a 35mm DIN rail.
When mounting note the following:
•
The controller should not be freely accessible after mounting. A protective housing should be used, if mounted
outside an electrical cabinet.
•
Ensure adequate air circulation to dissipate heat generated during operation.
•
Local installation regulations must be observed.
Mounting location terminal
•
On an easy accessible interior wall, approx. 1.5 m (4.5’) above the floor in an area of average temperature.
•
Avoid exposure to direct sunlight or other heat sources, e.g. the area above radiators and heat emitting
electrical equipment.
•
Avoid locations behind doors, outside walls and below or above air discharge grills and diffusers.
•
Location of mounting is less critical if external temperature sensors are used
Installation terminal
1.
2.
3.
4.
5.
Install the mounting plate straight to the wall or the flush mounting box. Make sure that the nipple with the
front holding screw is facing to the ground. Make sure the screw heads do not stand out more than 5 mm of
the surface of the mounting plate.
Connect the wires of the terminals to the communication wires according wiring diagram
Slide the two latches located on the top of the front part into the hooks of the mounting plate.
Lower the front part until located flat on the wall and the mounting plate is not visible anymore. Make sure
the connection cable does not get into the way.
With a Philips-type screw driver of size #2, carefully tighten the front holding screw to secure the front part to
the mounting plate. This screw is located on the front lower side of the unit. There is no need to tighten the
screw too much.
Connection base to terminal
•
•
•
•
Max. Distance: 200m (650ft)
Normal cables maybe used for wiring in an EMC-save environment. In an impaired EMC environment use only
shielded cables.
The operating voltage must comply with the requirements for safety extra-low voltage (SELV) as per
EN 60 730.
One terminal may drive up to 8 base units. See wiring for parallel connections. Total wire distance should not
exceed 200 m (650ft).
Conductor resistance will influence external temperature reading. 450 Ω will result in an increase of 1°C (2°F).
Compensate using UP-08 if external temperature is used to control unit.

TLR-D5 Engineering Manual
Control Functions
The controller is designed to control fan coil systems with up to three fan speeds.
s. The fan speeds may be controlled to
run manual or automatic. In automatic mode, the controller will change fan speeds according to the temperature
difference of room temperature and setpoint.
Setpoint
•
Economy set point shift XSBY: This function shifts the set point while the operation mode is Economy. The
heating set point WH is reduced and the cooling set point WC increased by the value of the Economy set point
shift XSBY.
•
Dead Zone Span XDZ: The dead zone span lies between the heating and the cooling set point. The user can
change the heating or cooling set points within adjustable limits.
•
Minimum and Maximum Set Point Limits: Limits the adjustable range of the loop set point. The limits for
heating and cooling sequence may be chosen individually.
Control Sequence
•
4-pipe or 2-pipe system: 4-pipe systems use one heating and one cooling stage. Heating and cooling mode
will switch according to demand. A delay is implemented to prevent unnecessary switching between heating
and cooling mode: Heat – Cool change over delay.
•
Switching Hysteresis: Defines the difference between switching on and switching off of an output. A small
hysteresis will increase the number of switching cycles and thus the wear on associated equipment.
•
Delay OFF: Prevents a too short running cycle for the fan and heating or cooling stages by setting a
minimum running time. Delay OFF applies to all heating and cooling stages.
•
Delay ON: Prevents a too short stopping cycle for fan and heating or cooling stages by setting a minimum
stopping time. Delay ON applies to all heating and cooling stages.
•
Heat Cool change over delay: For 4-pipe systems: Delays the switching between heating on cooling mode
in order to prevent a hunting of heating and cooling cycles.
•
Fan off delay: In case heating or cooling has been active and the unit is switched off or reached the set point,
a 60 seconds fan off delay is activated to prevent over heating of a heating stage or condensation on a
cooling coil.
•
Step by step switching: In order to reduce the startup load of large fan motors, fan stages will be switched
on and off step by step, going through low and medium before activating high fan speeds.
•
Mold protection. The fan will not stop when the setpoint is reached while this parameter is activated. This
way the room will still be ventilated although there is no need to vary the temperature. The valve will still be
controlled according to temperature need. The fan will still switch off once the unit is set to OFF.
Mold protection should not be used for fan-only systems!

TLR-D5 Engineering Manual
Input configuration
Frost protection
Priority for alarm conditions
Frost protection will activate if the control temperature sinks below 5°C (41°F).
1. Frost protection
Operation returns back to normal if the control temperature reaches 10°C (50°F).
2. Operation mode OFF (EHO)
Frost protection alarm is displayed as FP in the smaller digits on the LCD display. An
3. Comfort or Economy
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.
Frost protection should be disabled for cooling only systems. (Per default on TLR-D41-W01)
Temperature input
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.
Choose the active temperature input (intern or extern) for the controller
input with FC17. Setting FC17 = 1 uses external input as control input.
All other settings use internal sensor as control input

Additional functions of the external temperature input:
Following additional functions are available, in case the external temperature input is not used as control input.
Toggle of Economy and
comfort operation modes
Economy and Comfort modes are controlled through an external contact by
connecting the external temperature input to ground
Activation Delay: Defines the delay the binary contact has to be open before
Economy mode is activated.
This function may be used together with key card switches for hotels or motion
detectors for offices.
Remote enable
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.
Heat-cool changeover with
external switch
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
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.

TLR-D5 Engineering Manual
Output Configuration
General
Two options are available: 3-point or binary.
3-point output
If 3-point is selected a 3-point actuator may be driven. The actuator has an open input and a close input. Applying
power to the Open input will drive the valve or damper open, applying power to the close input will drive the valve or
damper to the closed position.
The running time of the actuator may be preset. We recommend to enter the maximum running time under maximum
load in order to make sure that the valve can fully close and fully open in any circumstance.
In order to open the valve or damper DO4 will be activated for the preset amount of time. After the expiration of the
running time DO4 and DO5 will be OFF. The valve is closed by activating DO5 for the preset amount of time.
Binary output
Two devices may be controlled in case the 3-point actuator setting is OFF. DO4 will control a heating and DO5 a
cooling device.
Reversing Valve
In binary output mode a reversing valve option is available. Select 1 if the reversing valve is to be activated while in
heating mode, select 2 if the reversing valve is active while the unit is in cooling mode
