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 expan-
sion 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.
To avoid serious personal injury and damage to the equipment:
• Improper installation and operation of this control could
result in damage to the equipment and possibly even
personal injury or death.
• 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. Apart from any
field replaceable fuse(s) there are no user serviceable
parts. Attempting to do so voids warranty.
It is your responsibility to ensure that this control is safely installed according to all applicable codes and
standards. tekmar is not responsible for damages resulting from improper installation and/or maintenance.
• Read Manual and all product labels BEFORE
using the equipment. Do not use unless you

The electrical drawing examples on the following
pages show the 482 in common applications. These
drawings have a brief explanation of what is being operat-
ed in each system. Choose the components in your sys-
tem and use the drawings as a guide to aid in wiring your
system. These are only concept drawings, not engineered
drawings. They are not intended to describe a complete
system nor any particular system. It is up to the system
designer to determine the necessary components for
and configuration of the particular system being designed
including additional equipment, isolation relays (for loads
greater than the controls specified output ratings) and any
safety devices, which in the judgment of the designer are
appropriate in order to properly size, configure and design
that system and to ensure compliance with building and
safety code requirements.
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 pre-
fer to mount the control inside a
larger electrical panel.
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.
Press down at the fingertip grips
on top of the front cover and pull
out and down.
Lift the front cover up and away
from the control.
Loosen the screws at the front
of the wiring cover.
The wiring cover pulls straight out
from the wiring chamber.
The base is ready for mounting.The control lifts up and away
from the base.
Press the control release clip
on the base inside the wiring
chamber and slide the control
upwards.
Remove the safety dividers
from the wiring chamber by
pulling them straight out of
their grooves.
There are 10 conduit knock-outs at the
back and bottom of the wiring chamber.

This section explains how to wire individual devices to the
tN4 Gateway. For step-by-step wiring, refer to the terminal
number on the right of the page.
• Before wiring ensure all power is turned off and take all
necessary precautions.
• Install the supplied wiring compartment barriers by sliding
them into the grooves provided to isolate the low and
high voltage wiring.
• Refer to the current and voltage ratings at the back of
this brochure before connecting devices to this control.
• All wires must be rated at least 300 V.
• High voltage wires should be 14 AWG conductors.
• Low voltage wires should be 18 AWG conductors.
• Strip all wiring to a length of 3⁄8in. or 10 mm for
all terminals.
• Only qualified personnel should attempt installation of
the tN4 Gateway.
• Provide a 15 A circuit for the power.
• An approved circuit breaker or power disconnect that
de-energizes the high voltage wiring should be located
near the tN4 Gateway, and marked as the 115 V (ac)
power disconnect for this device.
• 115 V (ac) high voltage power supply circuits must be
protected by 15 A maximum overcurrent protection.
• Connect 115 V (ac) hot (L) to terminal 2.
• Connect 115 V (ac) neutral (N) to terminal 1.
• Connect the ground wire to one of the ground screws
provided in the wiring chamber.
The tN4 Gateway includes five tN4 buses:
• tN4 Bus 0 (terminals 3 and 4)
• tN4 Bus 1 (terminals 5 and 6)
• tN4 Bus 2 (terminals 7 and 8)
• tN4 Bus 3 (terminals 9 and 10)
• tN4 Bus 4 (terminals 11 and 12)
Each tN4 bus consists of a tN4 terminal as well as a
C terminal.
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.

The following tests are to be performed using standard
testing practices and procedures and should only be car-
ried 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.
Test Meter
Control Terminals
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.
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.
The RS232 message includes the following:
1. FirmwareRevision
0xca 0x07 0x06 0x02 0x87 0x01 0x00 0x00 0x91 0x00
0x28 0x35
This means that the 482 firmware version is 6c hexadecimal
or 145 in decimal.
2. ProtocolVersion
0xca 0x07 0x06 0x02 0x8f 0x01 0x00 0x00 0x02 0x00
0xa1 0x35
The means that the 482 protocol version is 02.
The 482 then exits the test routine and resumes normal
operation.

Before connecting the tN4 Gateway to a tekmarNet®
system, it is recommended that the system be fully com-
pleted, with no tekmarNet®thermostats being added or
removed at a later date. Also, each tekmarNet® thermostat
is automatically assigned a tekmarNet®address when con-
nected to the system. When using a Gateway, each device
requires a manual address. This address should be written
down together with the room location for future reference
using the Job Record J 482 and will be required in order to
name the room on the home automation equipment.
The tN4 Gateway 482 can communicate and control the
following tekmar products:
• tekmarNet®Setpoint Control 161, 162

Each thermostat and setpoint control uses the following
format for addressing: Port:Bus:Thermostat Device.
The snow melting control does not reports its address to
the 482. The Bus and Thermostat Device are visible on
the thermostat and setpoint control’s 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 or b = 0 482 tN4 Bus 3 = 3
482 tN4 Bus 1 = 1 482 tN4 Bus 4 = 4
482 tN4 Bus 2 = 2
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.
The 406 tN4 bus numbering is dependent on the
WaterTemp and the Zone settings when configuring
the control.
