Caution
Improper installation and operation of this control could
result in damage to the equipment and possibly even
personal injury or death. It is your responsibility to
ensure that this control is safely installed according to all
applicable codes and standards. This electronic control
is not intended for use as a primary limit control. Other
controls that are intended and certified as safety limits
must be placed into the control circuit. Do not attempt
to service the control. Refer to qualified personnel for
servicing. Apart from any field replaceable fuse(s) there
are no user serviceable parts. Attempting to do so voids
warranty and could result in damage to the equipment
and possibly even personal injury or death.
Choosing a Location
The location of the tN4 Gateway is important. To ensure proper wiring during rough in, select an appropriate location for
the control early in the construction process. Consider the following:
Do not expose the tN4 Gateway to temperatures beyond
•
32 to 122°F (0 to 50°C).
Keep dry. Avoid potential leakage onto the control.
•
Relative humidity ≤ 92% to 104°F (40°C), down to 50%
•
above 104°F (40°C).
Provide adequate ventilation.
•
Keep away from equipment, appliances or other sources
•
of electrical interference.
Mount the enclosure to a solid backing.
•
Provide easy access for wiring and viewing.
•
•
Mount approximately 5 feet (1.5 m) off the finished floor.
Mount near the zone managers, reset modules, tN4
•
thermostats, tN4 setpoint controls, and mixing expansion
modules. The total wire length of each tN4 bus cannot
exceed 5000 feet.
Each tN4 bus consists of a pair of wires (tN4 and C).
•
The tN4 Gateway can accept up to 5 tN4 buses.
•
Use a Category 5 cable up to or less than 150 feet (45
•
m) in length to connect the tN4 Gateway to the home
automation equipment.

Mounting
Press down at the fingertip
grips on top of the front cover
and pull out and down.
Remove the safety dividers
from the wiring chamber by
pulling them straight out of
their grooves.
The control can be mounted on
a standard DIN rail. First remove
the control from its base and
then, using the hooks and spring
clip on the back of the control,
mount it onto the DIN rail. This
will be a popular option for those
who prefer to mount the control
inside a larger electrical panel.
Lift the front cover up and
away from the control.
Control release clip
Press the control release
clip on the base inside the
wiring chamber and slide
the control upwards.
The wiring can enter the bottom
or the back of the enclosure.
Knock-outs provided in the base
allow the wiring to be run in
conduit up to the enclosure. The
base also has holes that line up
with the mounting holes of most
common electrical boxes.
Loosen the screws at the
front of the wiring cover.
The control lifts up and
away from the base.
The wiring cover pulls straight
out from the wiring chamber.

Each tN4 bus consists of a tN4 terminal as well as a C
terminal.
C tN4
Polarity is important.
Connect each tN4 bus on the system to a tN4 bus input
on the 482. The tN4 bus order on the 482 is not critical;
however, it is recommended to connect them to the 482
in the same order in order to avoid confusion during
troubleshooting.
RS 232 Serial Port
Use a Category 5 cable with an RJ45 connector and plug
it into the 482 RS 232 serial port. Connect the opposing
end RJ45 connector into the RJ45 to DB9 adapter.
Cleaning
The 482 exterior can be cleaned using a damp cloth. Moisten the cloth with water and wring out prior to wiping the device.
Do not use solvents or cleaning solutions.

Troubleshooting the Wiring
General
The following tests are to be performed using standard
testing practices and procedures and should only be carried
out by properly trained and experienced persons.
A good quality electrical test meter, capable of reading
from at least 0-300 V (ac), 0-30 V (dc), 0-2,000,000 Ohms,
and testing for continuity is essential to properly test the
wiring and sensors.
Testing the Control
Testing the Power
1. Remove the front and wiring covers from the control.
2. Use an electrical test meter to measure (ac) voltage
between the Power N and L terminals (1 and 2). The
reading should be 115 V (ac) + / – 10%. The Power LED
should be on.
3. If power is not present the Power LED will be off. Check
the circuit(s) that supply power to the Power N and L
terminals (1 and 2).
Testing the tN4 Buses
1. Remove the front and wiring covers from the control.
2. There are a total of five tN4 buses (tN4 and C). The corresponding tN4 LED will be on if there is communication
on the tN4 bus.
3. If there is no communication on a tN4 bus that is supposed
to have communication, there may an open or short
circuit. An open or short circuit will be indicated as a bus
error on any tN4 thermostats, tN4 setpoint controls, and
tN4 system controls.
4. To test for short circuits:
Disconnect the tN4 bus wires on both ends.
•
Install wire nuts on each wire on one end to ensure the
•
wire ends are not touching.
Measure for continuity using an electrical meter.
•
If continuity is present, there is a short circuit fault
•
along the wires. It is recommended to replace the tN4
bus wires.
5. To test for open circuits:
Disconnect the tN4 bus wires on one end and connect
•
them together.
Disconnect the tN4 bus wires on the other end.
•
Use an electrical meter to measure for continuity.
•
If there is no continuity, there is an open circuit fault
•
along the wires. It is recommended to replace the tN4
bus wires.

###
Control Terminals
Testing the RS 232 Serial Port
A terminal shell called Termite can be used to test the RS
232 serial port hexadecimal data.
Step 1: Download the Termite (complete setup) terminal
program for Windows.
http://www.compuphase.com/software_termite.htm
Step 2: Settings
Baud rate = 9600, Data bits = 8, Stop bits = 1, Parity =
none, Flow control = none, Forward = none
Hex View = check marked
Step 3: Enter commands
Hexadecimal values can be entered in the command line
at the bottom. The hexadecimal numbers must be entered
in the format 0x00 followed by a space.
The 482 includes a built-in test routine that transmits a
message via the RS232 port. The result of this is that the
Tx indicator will flash as the message is sent.
Start the test routine by pressing the Test button for 1
second. The Test LED turns red.
Test
The RS232 message includes the following:
1. FirmwareRevision
0xca 0x07 0x06 0x02 0x87 0x01 0x00 0x00 0x6c 0x00
0x03 0x35
This means that the 482 firmware version is 6c hexadecimal
or 108 in decimal.
2. ProtocolVersion
0xca 0x07 0x06 0x02 0x8f 0x01 0x00 0x00 0x01 0x00
0xa0 0x35
The means that the 482 protocol version is 01.
The 482 then exits the test routine and resumes normal
operation.

tekmarNet® Home Automation Protocol
Several leading home automation control companies
have worked together with tekmar and have created
software drivers for the tN4 Gateway 482 and tekmarNet®
compatible products. These software drivers are available
from the home automation control company.
Refer to the 482 product page on tekmar’s website
http://tekmarcontrols.com/accessories/482.html
for details and a complete listing. The software drivers
allow easy integration of tekmarNet
automation system.
If you have a home automation system that is not listed
on the tekmar website, you may create your own software
drivers. This will require advanced programming skills.
The tekmarNet® Home Automation protocol is available

The 482 uses the following format to address each
thermostat: Port:Bus:Thermostat Device
Each thermostat is able to display the Bus and Thermostat
Device on the LCD display. This is documented as the
‘tekmarNet Address’ in the thermostat data brochure.
Port Number
The leading digit is the Port number. This determined by
the wiring connection that the thermostat is wired to on
the 482.
482 tN4 Bus 0 (terminals 3 & 4) = 0
482 tN4 Bus 1 (terminals 5 & 6) = 1
482 tN4 Bus 2 (terminals 7 & 8) = 2
482 tN4 Bus 3 (terminals 9 & 10) = 3
482 tN4 Bus 4 (terminals 11 & 12) = 4
Bus Number
The second digit is the thermostat bus number. The bus
number is pre-determined by the wiring of the thermostat
to a boiler or mixing reset control water temperature bus.
In the event that no reset control is installed, the bus
number is 0.

Thermostat Device Number
The third and fourth digits indicate the thermostat
device number. The thermostat device number is a
two digit number that ranges from 01 to 24 and can be
determined from the thermostat address. To determine
the thermostat address, please consult the data brochure
for the appropriate thermostat.
Example 1
A thermostat with bus and thermostat device number of
b:01 is wired to a model 400 controller boiler bus and in
turn is wired to the 482 on port 0. This address is 0101.
Example 2
A thermostat with bus and thermostat device number of
b:24 is wired to a model 423 controller boiler bus and in
turn is wired to the 482 on port 0. This address is 0424.
Example 3
A group of thermostats are wired together to create a standalone network. A thermostat with thermostat device number
15 is wired to the 482 on port 0. This address is 0015.
