Important Regulatory and Installation Requirements
Codes
The installation of this unit must
be in accordance with local
codes.
KWE P/N 394047 Versatronik 532 Solar/Modbus Gateway V1.0 09/2013 Technical information subject to change without notice
All electrical wiring is to be done
in accordance with the latest
edition of CSA C22,1 Part 1 and/
or local codes. In the U.S. use
the National Electrical Code
ANSI/NFPA 70.
The installing contractor must
comply with the Standard of
Controls and Safety Devices for
Automatically fired Boilers, ANSI/
ASME CSD-1 where required by
the authority having jurisdiction.
Working on the equipment
The installation, adjustment,
service and maintenance of this
unit must be done by a licensed
professional heating contractor
or persons who are qualified and
experienced in the installation,
service, and maintenance of
similar products. There are no
user serviceable parts on this
control.
Power supply
Install power supply in
accordance with the regulation of
the authorities having jurisdiction
or in absence of such
requirements, in accordance with
National Codes.
Purpose of Device and Operation
The Versatronik 532 Solar
gateway provides a
communication translation
between applicable controls and
DDC systems which are capable
of Modbus RS485
communications.
The Versatronik gateway may be
either part of a control panel or
stand-alone control device.

 Please carefully read this manual
prior to attempting installation.
Any warranty is null and void if
these instructions are not
followed.
 The completeness and
functionality of field supplied
electrical controls and
components must be verified by
those installing the device
!
WARNING
More than one live circuit. See
wiring diagram in this manual.
Turn off power supply to control
and damper/blower before
servicing. Contact with live
electrical components can result in
serious injury or death

Mounting Steps
1. Mount Versatronik 532 Gateway in a
convenient location near the solar control.
Remove cover by loosening the two screws on
either side of base to release the cover.
2. Fasten base to wall using field-supplied
screws/fasteners.
3. Remove knockout and installed wire strain
relief or box connector. Removal of remaining
knockouts is required to make further
connections.
4. Once all of the 120VAC and low voltage
connections are complete and verified, reinstall
the cover from Step 1.
!
WARNING
When extending wire there is the possibility of
exposure to electromagnetic interference. Avoid
running wires beside or near high voltage 120/240
VAC conductors. If proximity to high voltage
conductors cannot be avoided, use stranded, twisted
pair of shield design wire. Ensure that only one end of
the shielding is grounded.

Versatronik 532 Dial Setting Overview
Rotary Dial Setting
Setting Overview
1. The rotary dial setting on the Versatronik
Gateways provides addressing information for
systems that may utilize a number of
Versatronik Gateways.
Applications with the Versatronik 532 Solar
with RESOL controls, it is not required to
make adjustments to the rotary dial setting. It
should be left in the factory default position
setting of 0.
