Shielded Wire; Non-Communicating Equipment; Mounting - Observer TSTAT0201CW Installation Manual

Shielded Wire

If the thermostat wiring will be located near or in parallel with
high voltage wiring, cable TV or Ethernet wiring, then shiel-
ded thermostat wire can be used to reduce or eliminate po-
tential interference. The shield wire should be connected to
the C terminal, or ground, at the indoor unit. The shield wire
should NOT be connected to any terminal at the wall control.
Connecting the shield to ground at both ends can cause cur-
rent loops in the shield, reducing shield effectiveness.

Non-communicating equipment

The Observer® Control, when paired with the
NAXA00101DB daughter board, will operate non-communic-
ating equipment. When the system utilizes the
NAXA00101DB daughter board, the Observer Control oper-
ates as a standard universal thermostat. See Appendix Wir-
ing Diagrams

Mounting

First become familiar with all plastic assembly pieces shown
in Figure 2. The wall control will snap together with the
back-plate. A back-plate is supplied Figure 2. Attach
back-plate using only a small hole in the wall allowing a four
wire connection to pass through. Mount the assembly to the
back-plate.
NOTE: Once Observer Control is secured to wall with the
back-plate assembly (snapped together), care must be taken
not to bend or break the interlocking tabs when removing.
