1. Important notes
1.1 Intended use
The gateway is the connection point between the Ho-
val CAN bus and a Modbus interface via TCP or RS485
(RTU).
The gateway enables users to access and operate their
Hoval heating system via Modbus.
These instructions describe how to connect, install and
commission the interface.
1.2 Explanation of the symbols
1.2.1 Warnings
NOTICE
... indicates a situation of possible danger
which can lead to damage to property if not
avoided.
«Warning: dangerous electrical voltage» as a
warning for accident prevention.
Ensures that people do not come into contact
with electrical voltage. The danger sign with
the black lighting symbol warns against the
danger of electrical voltage.
1.2.2 Symbols

3. Installing and connecting the gateway
3.1 Installing the gateway in the wall housing or
control panel
• Install the gateway in the wall housing or control panel.
• It may be necessary to remove the gateway and the
connector base from the top-hat rail prior to this.
g. 06
3.2 Installing the gateway in the heat generator
If, after installing all modules and extensions, there is still
space in the heat exchanger, this can be used for the
gateway.
- See also “Technical Information Installation Instruc-
tions” in the “Electrical connection” chapter.

3.3 Connection for the heat generator (WEZ /
CAN bus)
There is a danger of electric shock.
The heat generator can only be de-energised
by disconnecting it from the mains (fuse).
NOTICE
The gateway can be connected to the CAN
bus at any point on the bus system.
•
In doing so, ensure that the CAN bus is
correctly terminated.
1. Plug the CAN bus into the gateway
or establish the CAN connection via the terminals on
the back of the gateway.

g. 08
If installing the gateway in the heat exchanger, cont-
inue to point 3:
2. Expose a basic or controller module in the heat gene-
rator, wall housing or control panel according to the
“Technical Information Installation Instructions” in the
“Electrical connection” chapter.
3. Connect the Hoval CAN bus to a basic or controller
module (g. 08) according to chapter 2.3.2
NOTICE
When using an external mains adapter, the
12 V line (CAN_V+) of the CAN bus must
NOT be connected.
4. Route the cable according to the "Technical Informa-
tion Installation Instructions" in the "Electrical connec-
tion" chapter.
NOTICE
The CAN bus cable must have strain relief
applied.

3.6 LED lights on the gateway
For commissioning it is important to know what status
the gateway is currently in. The LEDs indicate the current
status for this purpose.
The LED electrical power supply is green, all other LEDs
are dark.
• Gateway is in boot status, i.e. the operating system is
starting up – can take up to 60 seconds
