Installation
Digital Inputs
Digital inputs are used to receive status signals such as filter status, fan status, etc. Use unpowered dry contacts only with
18AWG two-wire twisted, stranded, shielded, or unshielded wire.

Power
The US5182 is powered from a 24 VAC +20/–5% transformer. If wiring for communications, dedicated power must be
used to power the device, rather than power from the HVAC equipment. Several TCS controllers may be powered from the
same transformer, provided that the transformer has enough power.
Connect the power source using 18AWG two-wire twisted, stranded, shielded, or unshielded wire.
NOTE:
Do
not connect to 120VAC. When multiple TCS devices are using a single transformer, the polarity of the power
wiring must be maintained. All TCS devices are half-wave rectified and have common return paths.
