General Description

The TCY3 is a stand-alone electronic universal controller with two autonomous control loops. Each control loop may use up
to 2 PID sequences and 6 binary sequences. The TCY3-T0121R features 1 NTC temperature sensor and 1 analog input, 2
binary outputs and one analog output. The outputs need to be assigned to the control sequences by parameters. A
detailed configuration is possible by following a simple setup routine. The TCY3 can be configured using the standard
operation terminal. No special tool or software is required.

Selection of actuators and sensors

Temperature Sensors:

Use only our approved NTC sensors to achieve maximum accuracy. Recommended is SDB-Tn10-20 as Duct sensor, SRA­Tn10 as Room sensor and SDB-Tn10-20 with AMI-S10 as immersion sensor.

Modulating Actuators:

Choose actuators with an input signal type of 0-10 V DC or 4-20 mA. Minimum and maximum signal limitations may be
set in software.

Floating Actuators:

Actuators with constant running time are recommended. Observe power limits on binary devices.

Binary auxiliary devices:

E.g. pumps, fans, on/off valves, humidifiers, etc. Do not directly connect devices that exceed 48 VAC, 2(1.2) A. Observe
startup current on inductive loads.

2. AI - Selection of input type:
a. Left position: voltage input (0…10 V),

factory default
b. Middle position: current input (0…20 mA)

Mechanical Design and installation

The unit consists of two parts: (a) The power case with attached mounting plate and (b) the front part.

Mounting location

• 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

1. Connect the wires to be connected to the terminals of the power case according to wiring diagram

2. Install the mounting plate to the flush mounting box. Make sure that the nipple with the front holding screw is

facing to the ground. Make sure the mounting screw heads do not stand out more than 5 mm (0.2”) off the
surface of the mounting plate.

3. Ensure that the jumpers are set correctly.

4. Slide the two latches located on the top of the front part into the hooks at the upper side of the mounting plate.

5. Carefully lower the front part until the interconnector reaches the mounting-plate. Continue pressing in a gentle

way until the front part is fully connected. While inserting the connectors, a slight resistance can be felt. This is
normal. Do not use excessive force!

6. 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.

Legend:

1. 4-digit display of current value, time, control parameter or set point

2. Unit of displayed value, °C, °F, % or none

3. Graphical display of output or input value with a resolution of 10%

4. 4-digit display of current value, time, control parameter or set point

5. Operation modes: Comfort mode, Standby mode, Energy Hold Off

6. Symbols:

Heating Active Cooling Active Schedule Set Direct Acting

7. POWER button: Standard function: Pressing the button less than 2 sec toggles standby and comfort mode.

Pressing the button for more than 2 seconds switches the unit off.
Programming function: ESC function, to return to previous level or ignore changed value

8. UP buttons: increment set points and parameters, select menu options

9. OPTION button: Standard function: If pressed less than 2 sec access for different control modes

If pressed for more than 2 sec starts operation level for advanced users. Change of time schedules, offsets and
heat – cool settings.
Programming function: Acts as Enter to select menu option or accept changed parameter value.

Operation Modes

• Comfort: The unit is in full operation mode. All the control functions are operating according to their setpoints.

The unit displays occupied mode.

• Standby: The set points are shifted according to parameters 1L00 or 2L00. The heating parameter is shifted

down and cooling parameter up. The unit displays unoccupied mode. Outputs are limited to OP04 standby
maximum. For two stages heating or cooling the second stage will not operate while in standby mode. Standby
operation may be disabled with UP06.

• Energy Hold-Off (EHO): The unit is turned off, and "Off" is displayed. However, the inputs are still monitored and

the alarm functions will operate normally.

Activation of operation modes

• Via operation terminal

• Clock (Deluxe version only): Operation modes may automatically be switched according to daytime and weekday.

The clock symbol will be indicated if time programs are activated.

• Infrared Remote Controller (Deluxe version only): use OPR-1 to control the unit remotely

TCY3-T0121R Operation

Operation of the Terminal Unit

Switching ON

The unit is switched on by pressing the POWER button. It will start up in comfort mode.

Changing between COMFORT and STANDBY

Pressing the POWER button for less than 2 seconds toggles between STANDBY and COMFORT modes. Standby mode may
be disabled with UP06.

Switching OFF

Pressing the POWER button for more than 2 seconds, will switch the unit off. OFF and current time will be displayed in the
LCD for the deluxe unit. Current temperature and OFF is displayed for the basic unit.

Standard display

Standard display is enabled with parameter UP08. This display mode is active if no UP/DOWN or OPTION key has been
pressed during the previous 30 seconds. The contents of the large and small digits may be chosen with parameters UP09
to UP10.
Should Standard display be disabled, the selected loop setpoint will be displayed in the small digits, the associated input
in the large digits and the output in the right hand scale.

Changing of set points

If two control loops are enabled, step through loop 1 and loop 2 by pressing the OPTION/RIGHT button. The large digits
show Lp1 and Lp2 alternately with the set point of that loop shown in small digits. With the desired control loop displayed
change its set point with the UP/DOWN buttons. If only one control loop is enabled press the OPTION/RIGHT button to
display set point in small digits and adjust with UP/DOWN buttons (Lp1 or Lp2 is not shown). Changing of setpoints may
be disabled with UP01.

Override of secondary set point in cascade control

If cascade control is active (for example VAV control), it is possible to override the primary loop and manually set the set
point of the secondary loop. While the secondary loop is displayed change the set point with UP/DOWN keys. The manual
indication will show on the display. (For VAV this would mean the loop is now changed to CAV. This is especially useful
while tuning the VAV system) Pressing the OPTION key to move back to the temperature loop will cancel manual override.
Manual override may be disabled with UP02.

Power Failure

All the parameters and set points are memorized and do not need to be reentered. Depending on UP05 the unit will
remain switched off, switch on automatically or return to the operation mode it was in before the power failure.
Deluxe version only: Timer operation and daytime setting will be retained for 24h. The controller has to be connected to a
power supply for at least 10 hours for the backup function to operate accordingly.

Clock Operation (Deluxe Version)

The TCY3 contains a battery backed up quartz clock. Up to 16 mode changes (STANDBY, COMFORT, OFF) based on
weekdays and time may be programmed. See chapter operation on how to program and assign switch times to the
corresponding loops.
A blinking clock indicates that the time has not been set. This may occur if the time was never set or if the unit was
without power for longer than 24 hours. The time needs to be set in order to allow time programs to operate. See chapter
operation, advanced settings for instructions on how to set the time.

Error messages

The TCY3 may display the following error condition:

Err1: Temperature sensor faulty or missing. The connection to the temperature sensor may be interrupted or the

Err2: The internal humidity sensor is damaged or missing. All outputs connected to this sensor will be set to off mode.

Err3: Problem with the internal real-time clock. Time schedule programs are not operating, time related functions will

temperature sensor is damaged. All outputs connected to this sensor will be set to off mode. Sensor feedback
signals will be set in alarm mode.

Sensor feedback signals will be set in alarm mode.
