2.2 About the controller
The LogoTronic HIU controller V2 was developed to control heat interface units (HIU) in heating
networks. The controller is not a finished product but is instead supplied installed and prewired
as a component of a heat interface unit.
The controller is designed solely for installation in a finished product (heater) and is supplied
solely to manufacturers of heating products.
If the controller is installed outside the heating equipment, corresponding tensile loads on the
cables must be taken into account.

We reserve the right to change designs and technical specifications of our products.

2.3 Safety symbols and stickers
1) in the lower le corner of the transparent
cover, the "High voltage" symbol pursuant to
EN ISO 7010 (20 mm) and the "Read manual"
symbol pursuant to EN ISO 7010 (20 mm),
see image.
2) on the right-hand side of the internal cover
plate next to the fuse-holder and the word
"FUSE":
a sticker with the lettering "2A T" (black lettering,
3.5 mm high), see image
3. Installation
The LogoTronic HIU controller is installed, prewired and tested in the heat interface unit during
production. The controller is supplied with a mains power adapter which is connected to the controller
by a plug. The end of the cable to be attached to the mains is open and must be hard-wired.
The protective earth wire (PE) must be connected from the mains to the controller. The protective
earth wire must also be connected from the controller to the metal parts of the heating product.
The electrical connection work to be performed during installation in the dwelling will depend on
the system used. In the simplest case, only the power supply and the protective earth wire will need
to be ensured. For this purpose, the mains cable supplied must be plugged into the power supply.
The dierent connectors are shown in colour in the image on page 8. The connectors in the yellow
rectangles are prewired during production and are not designed for further connections at the
installation site.
The mains cable is also connected with the controller during production. The mains connection
device is the three-wire connector labelled with the green rectangle.
The mains connection device must be hard-wired. We recommend the use of a 3A fuse.

7.1.2 LED displays 1-5
The LEDs display the status.
Each LED can be either "OFF", "ON", "Flashing slowly" (FLS) or "Flashing fast" (FLF):
- Flashing slowly (FLS) means that the LED alternates between ON for 1 s and OFF for 1 s
(flashingfrequency of 0.5 Hz).
- Flashing fast (FLF) means that the LED alternates between ON for 0.25 s and OFF for 0.25 s
(flashing frequency of 2 Hz).
LEDs 1 to 4 show the corresponding status of the controller in normal operating mode. This means that
LED 1 lights up when the room thermostat connected to CON25 has closed its zero-potential contact.
