Herz clever&smart Control Box Clima Instruction Manual

HERZ clever&smart Control Box Clima
Description
The HERZ clever&smart Control Box Clima is a universal heating and zoning controller for Surface heating and cooling
systems. In conjunction 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 and surface cooling
with intuitive operability. The inputs and outputs can be freely assigned via HERZ clever&smart Room Controller Clima,
so that different heating and cooling systems can be implemented.
Important characteristics of the HERZ clever&smart Control Box Clima:
Control of 8 heating and cooling zones with 1 - 4 thermoelectric actuators each
l
Detection of room temperature and humidity in conjunction with HERZ clever&smart Room Controller,
l
HERZ clever&smart LEDcontroller or HERZ clever&smart Room Sensor
Optional: Weather compensated via an external temperature sensor
l
Optional: Dew point dependent via room humidity measurement
l
Optional: Control heating circuit pump and mixer (PWM oder 0-10V) possible
l
2 separate CAN bus interfaces for building network and private floor or apartment network
l
Connectable with other HERZ products via CAN bus
l
Control of mixers, valves and energy generators via 0-10V / PWM
l
2 additional floating changeover contacts (terminals J and K) for flexible assignment with additional functions
l
Innovative strain relief and coloured terminal strip
l
Up to 20 1-Wire temperature sensors can be connected (incl. a maximum of 8 LEDcontroller)
l

Safety Instructions

General
By no means does the controller replace the safety appliances on site!
l
Temperature values which are set too high can lead to scalding or damage to the system. Scalding protection must
l
be provided by the customer!
The temperature sensor cables must be routed separately from mains voltage cables, and must not, for example,
l
be routed in the same cable duct!

Wall Installation

Install the controller only in dry areas and under the ambient conditions described in "Specifications".
l
Low-voltage cables such as temperature sensor cables must be routed separately from mains voltage cables. Feed
l
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 unit by pressing it down. Ensure
that the locking catches engage completely and that the unit 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 reinstalled 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 attachment
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)
Heating zones with 230 VAC actuators
Heating zones with e.g. 24 VAC actuators (separation wall)

LED A Lights up if mains voltage is present and relay A is switched.
LED B - K Lights up if relays B - K are switched
Lights up if the private CAN bus is active.
LED L
Flashes at 1 Hz (60 x / minute) if there is an error in the private CAN bus.
Lights up if the building CAN bus and the 1-wire bus are active.
Flashes at 1 Hz (60 x / minute) if there is an error in the building CAN.
LED M
Flashes at 3 Hz (180 x / minute) if there is an error in the 1-Wire connection. EXCEPTION: If the building CAN
bus remains unused, a flashing of the LED M is normal and does NOT mean that there is a error.
LED N Lights up if outputs V1, V2 or V3 are active.
