Control Location
•
• The Wiring Center can be mounted either directly to the wall,
or to a 4”x4” electrical box.
•
• Mount the enclosure to a solid backing.
•
• Wiring will enter through either side knockouts or between the
base of the enclosure and the cover on the sides and top. See
Figure 1 and Figure 2.
Note: The nonmetallic enclosure does not provide grounding
between conduit connections. Conduit connections must be
grounded by other means.

This Quick Setup Guide contains the basic information required to get your new tekmar tN4 Wiring Center 315 installed
and operational. An Installation and Operation Manual D 315 containing all available features and operational details is
included with this control or can be found at www.tekmarcontrols.com/literature.html
The tN4 Wiring Center 315 is designed to be mounted near a zone manifold and will operate up to 6 zone valves in a
hydronic heating system.
Wire the Thermostats
tN4 Thermostats:
•
• Connect tN4, C, R and W conductors to the corresponding
terminals on the 315, paying special attention to ensure that the
tN4 and C wires are not reversed. See the terminal labelling in
Figure 2.
Wire the Zone Valves
•
• Wire the zone valves to the Vlv and C terminals on the 315,
as shown in Figure 3.
•
• End switches on zone valves are not required when using
the 315.
Connect to the Mechanical System
•
• If the 315 is to be connected to a tN4 network, connect the
tN4 and C expansion terminals to the tN4 connection on the
associated tN4 device.
•
• If the 315 is to be connected to another control, such as a
tekmar Boiler Control, use the end switch terminals to create
a ‘Boiler Demand’ on this external control. See application on
next page.

Wire the Power Supply
Once the transformer has been correctly sized, connect the 24 V
(ac) leads from the transformer to the R and C terminals marked
“Input Power” on the Wiring Center. See “Sizing the External
Transformer” in the Installation and Operation Manual D 315 for
more detailed information.
