Table 1 — VAV-RTU Open Inputs and Outputs
(1) Safety Chain Feedback: 24Vac required at this terminal to provide “Run Enable” status. See Input/Output section for additional instructions.
(2) These inputs are configurable. If installed, they take the place of the default input on the specific channel. See appropriate Input Configuration Sec-
tion for wiring and setup instructions.
(3) Parallel pins J5 - 1 = J2 - 6, J5 - 3 = J1 - 10, J5 - 5 = J1 - 2 are used for field installation.
(4) Refer to the input configuration and accessory sections for more detail.
