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.

Temperature Inputs

Connect 1000Ω PtRTD temperature sensor inputs (range of -40ºF to 160ºF) using 18AWG two-wire twisted, stranded
shielded wire, maximum 250 ft. length. Sensors can be used for remote room temperature, discharge air temperature,
outdoor air temperature or mixed air temperature. Sensor wires should be kept at least five feet from live voltage wiring.
NOTE: When using remote sensors, the unit may need to be calibrated See the
information.
