immediately.
• Use only original replacement parts and accessories of the manufacturer.
• You must not alter, remove or render illegible any labels on the equipment which have been
aixed by the manufacturer.
• Undertake only those adjustments to the equipment’s settings that are described in these
instructions.
1.2 Intended use
The components listed in the following instructions are intended for use in heating systems
according to DIN EN 12828.
The LogoTronic Hub OTC is an automatic regulation and control unit within the meaning of IEC60730-1.
It is used as a client for forwarding an outside temperature sensor value via Modbus to several
LogoTronic controllers (servers for electronically controlled interface stations).
The LogoTronic Hub OTC and associated peripherals may be used only for the control of thermal
systems. All the specifications described must be adhered to in its use. The LogoTronic Hub OTC may
be installed and set up only by a specialist. The installer must first have read and understood the
instructions. The installer must explain all the relevant functions to the operator. The housing must
be intact and sealed prior to operation.

The equipment has been produced and tested in compliance with high quality and safety requirements.
Excluded from warranty and liability are personal injury and damage to property which may, for example,
be attributed to one or more of the following causes:
• Failure to observe these installation and operating instructions
• Improper installation, commissioning, maintenance and operation
• Improperly executed repair work
• Any actions in contravention of the "Alterations to the equipment" section
• Improper use of the equipment
• Situations in which values below or in excess of the tolerances listed in the technical data occur
• Force majeure
1.4 Disposal and hazardous substances
The equipment complies with European RoHS Directive 2011/65/EU on the

2.3 Safety symbols and stickers
The LogoTronic Hub OTC is marked with the following symbols:
1. in the lower le corner of the
transparent cover, the "High
voltage" symbol and the "Read
manual" symbol, see figure
2. on the inner cover plate to the
right of the fuse holder and the
word "FUSE": a sticker with the
inscription "2A T", see figure
3. Installation
The LogoTronic Hub OTC is supplied with a mains power cable which is connected to the LogoTronic
Hub OTC by a plug. The end of the cable to be attached to the mains is open and must be hard-wired.
The mains connection device is the three-pole connector, see Chapter 3.1 Item (A).
The mains connection device must be hard-wired. We recommend the use of a 3A fuse.
