Introduction
The tekmarNet®4 Gateway 482 provides RS 232 serial communication between tekmarNet® Thermostats and third party automation systems. The third party automation system is able to monitor and adjust the thermostat’s heating, cooling, and ventilation fan settings. Through the use of third party device drivers written for this product, tekmarNet® systems are fully integrated into home automation systems.

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.

Remove the safety dividers from the wiring chamber by pulling them straight out of their grooves.
Press the control release clip on the base inside the wiring chamber and slide the control upwards.

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.
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.

Electrical Drawings
The electrical drawing examples on the following pages show the 482 in common applications. These drawings have a brief explanation of what is being operated in each system. Choose the components in your system 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.
