The con- trol will learn and apply the minimum run time required to heat or cool the space to setpoint for the first Occupied period of a day.

The control will have Software controllable Mode Switches (Heat, Cool, and Fan).

The control will meter and track Unoccupied Override Time for billing purposes.

OPTIONAL COMMUNICATION TRANSLATOR

Overview

The ModLINC translator operates as a Modbus® Client pro- viding an interface between a BACnet® control system and devices that communicate using the Modbus® RTU protocol. The ModLINC is preconfigured to provide an interface to YORK UP products equipped with an Intelli-Comfort or Sim- plicity-Elite controller and allows monitoring and control by a third-party BACnet® Building Automation System (BAS).

The ModLINC mounts inside the control panel of the UP unit and utilizes 24 VAC power from the unit's control transformer. One port is connected to the UP controller. The other port must be connected to the BACnet® network.

The ModLINC translator is preconfigured to obtain opera- tional data points from the controller and expose them on a BACnet® network.

"The ModLINC device is primary a control offered and config- ured by York's ESG (Engineering Systems Group). The device can be used with other BACnet® MS/TP systems, but a qualified controls contractor must be involved. UP cannot support the ModLINC device beyond its hardware functional- ity and cannot guarantee functionality with the ISN or other third party BAS devices."

Please refer to the ModLINC Installation/Application manual Part Number 126367.
