This module determines the effective WarmupCooldown status for single duct VAV applications by evaluating the Network Input and the automatic Warmup mode based on the supply air temperature. The module issues a warmup status ANY TIME the SA-T (Supply Air Temperature)meets the requirements necessary for warmup (that is, both SA-T and ZN-T are reliable and SA-T > [ZN-T+Differential]). If both SA-T and ZN-T are reliable and the SA-T is not warm enough to trigger warmup, the WC-C (WarmupCooldown) network input is not allowed to force warmup (remains in Normal). The module state output is the effective WarmupCooldown mode for the application.
