System structure
Description
The HERZ clever&smart Control Box Heating is a universal heating and individual room controller for surface heating
systems. In combination with HERZ clever&smart Room Controller, HERZ clever&smart Room Sensor or HERZ
clever&smart LEDcontroller, this enables efficient use and function control of your surface heating with intuitive
operation. The inputs and outputs can be freely assigned via HERZ clever&smart Room Controller so that a wide
variety of heating systems can be implemented.
Important characteristics of the HERZ clever&smart Control Box Heating:
lControl of 8 heating zones with 1 - 4 thermostatic radiator valves each
lMeasurement of room temperature and humidity in combination with HERZ clever&smart Room Controller, HERZ
clever&smart LEDcontroller or HERZ clever&smart Room Sensor
loptionally weather compensated via an external temperature sensor
loptional control of heating circuit pump and mixer (PWM oder 0-10V) possible
l2 separate CAN bus interfaces for building network and private floor or apartment network
lconnectable with other HERZ products via CAN bus
lControl of mixers, valves and energy generators via 0-10V / PWM
l2 additional floating changeover contacts (terminals J and K) for flexible assignment with additional functions
linnovative strain relief and coloured terminal strip
lUp to 20 1-wire temperature sensors can be connected (incl. a maximum of 8 LEDcontrollers)
Safety Instructions
General
lBy no means does the controller replace the safety appliances on site!
lTemperature values which are set too high can lead to scalding or damage to the system. Scalding protection must
be provided by the customer!
lThe temperature sensor cables must be routed separately from mains voltage cables, and must not, for example,
be routed in the same cable duct!
Wall Installation
lInstall the controller only in dry areas and under the ambient conditions described in “Specifications”.
lLow-voltage cables such as temperature sensor cables must be routed separately from mains voltage cables. Feed
temperature sensor cables only into the left-hand side of the unit, and mains voltage cables only into the right-hand
side.
Wall Installation
Fix the DIN rail horizontally to the wall using screws.
Installation
1. Place the Control Box on the upper edge of the DIN rail with the
locking catch on top. 2. Engage the device by pressing it down.
Ensure that the locking catches engage completely and that the
device is firmly seated on the rail.
Disassembly
Remove the Control Box from the DIN rail by inserting two
screwdrivers into the eyelets and pulling them down-wards.
Separation walls and cover
The separation walls and the cover can be removed for easier
connection of the cables. They must then be rein-stalled in order to
safely separate areas carrying mains voltage from areas carrying low
voltages.
Open the cover (90 ° degree) and then pull it out of the attach-ment
laterally.
If the terminal blocks (B-I) are to be supplied with a voltage other than the mains voltage,
proceed as follows:
1. Remove existing bridges A1 - B1 and A2 - B2
2. It is absolutely necessary to insert a separating wall between A - B.
3. Connect the power supply to B1 (L) and B2 (N).
4. Observe max. switching power of relay and fuse (4 AT)

EU-Conformity
By affixing the CE mark to the unit the manufacturer declares that the HERZ clever&smart Control Box Heating conforms
to the following relevant safety regulations:
lEU low voltage directive 2014/35/EU
lEU electromagnetic compatibility directive 2014/30/EU
lEU RoHS Directive 2011/65/EU
lEU WEEE Directive 2012/19/EU (Reg.nr. DE 23479719)
conforms. Conformity has been verified and the corresponding documentation and the EU-declaration of conformity are
kept on file by the manufacturer.
Changes to the Unit
lChanges, additions to or conversion of the unit are not permitted without written permission from the manufacturer.
lIt is likewise forbidden to install additional components that have not been tested together with the unit.
lIf it becomes clear that safe operation of the unit is no longer possible, for example because of damage to the housing,
turn the Unit off immediately.
lAny parts of the unit or accessories that are not in perfect condition must be exchanged immediately.
lUse only original spare parts and accessories from the manufacturer.
lMarkings made on the unit at the factory must not be altered, removed or made illegible.
lOnly the settings described in these instructions may be set using the Unit.
Changes to the unit can compromise the safety and function of the unit or the entire system.
Warranty and Liability
The Unit has been manufactured and tested with regard to high quality and safety requirements. The unit is subject to the
statutory guarantee period of two years from the date of sale. The warranty and liability shall not include, however, any
injury to persons or material damage that is attributable to one or more of
the following causes:
lFailure to observe these installation and operating instructions.
lImproper installation, commissioning, maintenance and operation.
lImproperly executed repairs.
lUnauthorized structural changes to the unit.
lUse of the device for other than its intended purpose.
lOperation above or below the limit values listed in the ‚Specifications‘ section.
lForce majeure.
Disposal and Pollutants
The unit conforms to the European RoHS 2011/65/EU for the restriction of the
use of certain hazardous substances in electrical and electronic equipment.
Under no circumstances may the device be disposed of with the normal household waste. Dispose of the
unit only at appropriate collection points or ship it back to the seller or manufacturer.
Electrical Connection
lBefore working on the unit, switch off the power supply and secure it against being switched on again!
Check that there is no power flowing! Electrical connections may only be made by a specialist and in
compliance with the applicable regulations. The unit may not be put into operation if there is visible
damage to the housing, e.g. cracks.
lThe customer must provide an all-pole disconnecting device,
e.g. an emergency heating switch.
lLow-voltage cables such as temperature sensor cables must be routed separately from mains voltage
cables. Feed temperature sensor cables only into the left-hand side of the unit, and mains voltage cables
only into the right-hand side.
lWire ferrules made of brass can be difficult to clamp due to their asym-metric crimping shape. In this
case, remove the wire ferrule. The plug-in terminals are also suitable for flexible cables.
The strain reliefs are suitable for flexible cables with
a cable sheath diameter of 5 mm to 8 mm, primarily
using the lower strain relief (as shown).
The cables must be checked for firm placement.
Solid, thicker and thinner cables must always be laid
firmly and must be fixed on the installation side.
Solid cables or wires with special wire end ferrules
can simply be pushed into the ter-minals.
For other wires, the terminal must first be completely
pressed on with a screwdriver as shown.
setup wizard
The commissioning wizard in the HERZ clever&smart Room Controller starts automatically when the unit is commissioned for
the first time and guides you through the necessary basic settings in the correct order. Press the arrow keys in the upper
right/left corner to return to the next or previous setting.
Commissioning must also be completed on all other HERZ clever&smart Room Controller in the network.
The HERZ clever&smart Control Box Heating is configured exclusively on a HERZ clever&smart Room
Controller.
The setup wizard is restarted via the "Factory settings" menu item.
