General safety instructions
Recognised codes of engineering practice, especially the safety requirements and accident prevention regulations must beobserved when performing all assembly, wiring and commissioning procedures.
Only specially trained and qualified personnel are permitted to perform the assembly, wiring and commissioning.
The electrical installations must be implemented in compliance with the current valid EN / VDE / DIN and local electrical regulations.
Danger:
Electric shock by touching live parts.
Electrical devices may cause electrical hazards during operation
Before installation/assembly works begin:
Disconnect all poles or switch off supply voltage of TROX UNIVERSAL controller.
Protect power supply against unauthorised or unintended restart.
All installation operations may only start after these safety operations.

Please observe installation orientation
Explanation:
The TROX UNIVERSAL controller TCU3 may only be installed as follows:
at horizontal ducts: (Left image part)
The installation is only approved at the duct sides – an installation above or below the duct is not allowed.
at vertical ducts: (Right image part)
In this case all installation orientations are approved.
The descripted installation orientation must be applied.
Otherwise accurate volume flow measuring is not possible.
Power supply
Supply voltage 24 V AC / DC
Technical data:
– Supply voltage 24 V AC ± 15% 50-60 Hz
– Supply voltage 24 V DC ± 15%
– Fuse 2A slow, 250 V; glass tube fuse 5×20 mm
– Power consumption up to 40 VA (Maximum configuration)
Maximum power consumption is determined by the individual controller configuration.
Typical configurations will lead to following values:
| Volume flow or pressure controller with standard actuator | up to 15 VA |
| Volume flow or pressure controller with spring return actuator | up to 20 VA |
| Volume flow or pressure controller with fast running actuator | up to 29 VA |
| Room control panel | plus 4 VA |
| room or duct pressure sensor PT699 | plus 1 VA |
Important wiring instructions:
Observe polarity
Polarity of DC and AC supply voltage has to be strictly complied for all contollers during wiring.
Never connect 24 V AC and DC at same time
Limited wiring in a row
Power supply wiring in a row (via double terminals) is only approved for a maximum of 5 controllers!
Supply voltage at analogue inputs for supply of sensor/transducer
Type of used controller power supply (AC/DC) will influence type of provided power supply at analogue inputs:
TCU3 Power suppy 24 V AC → Provided sensor supply at AI1-AI5 is 24 V AC
TCU3 Power suppy 24 V DC → Provided sensor supply at AI1-AI5 is 24 V DC
This may require attention for connected sensors.
Mains supply voltage 230 V AC
Alternative power supply
(only with expansion module EM-TRF or EM-TRF-USV)
Technical data:
– Supply voltage 230 V AC +- 20% 50-60 Hz
– Fuse 500 mA slow , 250 V
– Power consumption up to 40 VA (Maximum configuration)
Important wiring instruction:
– Never connect 230 V and 24 Vsupply voltage simultaneous at one controller.
– Never connect 24 V supply voltage at controller with built in expansion module
EM-TRF or EM-TRF-USV
Supply voltage at analogue inputs for supply of sensor/transducer
TCU3 Power suppy 230V AC→ Provided sensor supply at AI1-AI5 is 24 V DC
(with EM-TRF, EM-TRF-USV)
This may require attention for connected sensors.

Control of on-site provided lighting / device (only at room controller with activated RMF)
For safety reasons the TCU3 casing must be locked in such a way that it can only be opened with a tool when a 230 V power supply is connected.
A safety latch with a sticker is available, which can be ordered under EM-TRF-Zubehoer (A00000055540).
When delivered with transformer module EM-TRF or EM-TRF-USV, this is installed and is not required additionally.

System design – Pressure control
Example 1: RMF-Function activated on pressure controller
Example 2: RMF-Function activated on other room volume flow controller
Pressure control connections:
Power supply for pressure transducer
The power supply of the pressure transducer can be provided by the EASYLAB TCU3 via 24V connector of analogue input X5 AI Sensor.
Important:
TCU3 supplied with 24 V AC → Connector 24V of X5 AI Sensor provides 24V AC
TCU3 supplied with 24 V DC → Connector 24V of X5 AI Sensor provides 24V DC
TCU3 supplied with 230V AC → Connector 24V of X5 AI Sensor provides 24V DC.
The above mentioned different supply voltage types must be observed depending on selected pressure transducer type.
Huba Pressure transducer type 699
This transducer is approved for AC and DC power supply type.
Therefore no adaption is required.
Briem Pressure transducer type GB604 MF 0,75
This transducer is approved for AC and DC power supply type.
Therefore no adaption is required.
Old Briem transducer must be manually adapted to the power supply type.
Default delivery setting ist AC supply.
Using a 230 V AC supply for the TCU3 via EM-TRF or EM-TRF-USV or 24 V DC supply implies a manual change of the supply to DC type.
Therefore change jumper setting from AC to DC within the Briem transducer casing.
