Thermostat Wiring
The thermostat can be wired in three different ways.

- Similar to tekmarNet
®
4 wiring with tN4 wiring terminal not used. First
stage heating relay (Rh - W1) can be wired directly to switching relays.
tekmarNet
®

- Allows the thermostat to be wired using 4 wires to a tN4 Wiring Center
or Zone Manager. The tN4 communication bus can also be daisy-chained to allow
multiple thermostats to be connected together without home running wires back to the
mechanical room.
tekmarNet
®
2
- Allows the thermostat to be wired point-to-point using 2 wires to a tN2
Wiring Center, House Control, or Zone Manager. This allows easy wiring for retrofit
applications.
Application specific wiring diagrams are provided in the 553_A brochure.
