246653-YTG-E-0108

The control will use a Wall Sensor that has a warmer/cooler dial so the occupants can offset the programmed setpoint by a programmed amount between 1 and 5 degrees.

The control will have a Supply Air Sensor as standard.

The control will have a Return Air Sensor as standard.

The control will have an Outside Air Sensor as standard.

The control will use the Return Air Sensor in place of the Space Sensor if the Space Sensor fails for any reason, the control will have a 365 day Real Time Clock.

The Real Time Clock will be able to do automatic Daylight Savings Time adjustment.

The control will have an Occupancy Schedule that allows two different Occupied schedules per day for each of the seven days of the week individually.

The control will have 20 Holiday Schedules, each capable of 99 days.

The control's Holiday Schedules will have a start time associ- ated with each schedule.

The control will control the Economizer directly.

The control will be capable of operating the Economizer using Dry Bulb, Outside Enthalpy, or Differential Enthalpy.

When the control is using Enthalpy to control the Economizer, it will also have an Outside Air Temperature enable Setpoint.

The control will use two setpoints for Supply Air Temperature for the Economizer operation. One will be for a small space cooling demand and one for a large space cooling demand.

The control will have the ability to do Demand Ventilation using one CO2 sensor.

The control will have a programmable maximum Outside Air Damper Position for IAQ operation.

The control will have the ability to temper the ventilation air during times when heating or cooling is not required.

The control will have the ability to offset the operating set- point based on high Humidity in the Space.

The control will have programmable limits when offsetting the Operating Setpoint to control Humidity.

The control must be able to lockout Cooling below a program- mable Outside Air Temperature Setpoint.

The control will be able to lockout Heating above a program- mable Outside Air Temperature Setpoint.

The control will have a Space Temperature Alarm.

The control will have a Supply Air Temperature Alarm for Heating and Cooling. The Alarm temperature will be pro- grammable

The Control will be able to do a Pre-Occupancy Purge at a Programmable Time.

The control will have a hardware Smoke-Purge input.

The control will have the ability to read a dirty filter switch

The control will have the capability of reading a Fan proving switch.

The control will have an intelligent recovery function that will bring the space to the Occupied Setpoint just before or at the beginning of the first Occupied schedule each day. 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.
