Thermostat Wiring
The thermostat can be wired in three different ways.
Stand Alone - 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
® 4 - Allows the thermostat to be wired using 4 wires to a tN4 Wiring Center
or Zone Manager point-to-point. Alternatively, the thermostat can operate the heating
and cooling equipment locally and the tN4 communication bus can be daisey-chained
from one thermostat to another.
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.
