CONTROL MODULE
Digital control inputs are low-current, resistance-based signals. For optimum
temperature control performance, it is recommended that the sensor inputs (zone
sensors, discharge air sensors, etc.) that are connected to the controller be routed
to the unit in one of the following manners:
• In separate field-supplied conduits, isolated from 24 VAC controls and line
voltage power to the unit, OR
• If the sensor wires are to be run in the same field-supplied conduit as 24 VAC
control wiring, use shielded cable and bundle wires separately from 24 VAC
control wiring. The shield must be drained at the unit and taped on the opposite
end.
