SETPOINTS SCREEN

OVERVIEW

This screen, accessed from the Unit screen, provides a convenient location for programming the most common setpoints involved in the chiller/condensing unit control. The setpoints depend on the type of unit.

Values on this screen are only pro- grammable if the chiller/condensing unit is in remote control mode. These values are only viewable if the unit is in local mode.

DISPLAY ONLY

None

PROGRAMMABLE

Leaving Chilled Liquid Temperature or

Return Chilled Liquid Temperature or Suction Pressure or Discharge Air Temperature Setpoint

This value allows the user to define the cooling setpoint that is to be maintained by the chiller/condensing unit. See the unit’s Installation, Operation and Maintenance Manual (IOM) for it’s programmable range.

Leaving Chilled Liquid Temperature or Return Chilled Liquid Temperature or Suction Pressure or Discharge Air Temperature - Control Range

This is the maximum allowable positive and negative deviation that is acceptable from setpoint in the system application. See the unit’s Installation, Operation and Maintenance Manual (IOM) for it’s programmable range.

Remote Chiller Run or Remote Unit Run

The chiller/condensing unit can be selected to either Run or Stop. Selecting Stop will command the chiller/condensing unit to shut down. Selecting Run will allow the chiller/condensing unit to turn on.

Current Limit Setpoint

This is the motor current limiting setpoint. The chiller will be limited from loading when the motor current equals or exceeds this value. Typically, for most instal- lations, no limiting is required and the programmed limiting will be set at or above 100%.

Load Limit Setpoint (YCAL Chillers)

Load Limiting can be programmed from 0 to 2. Load Limit 0 = no load limit

Load Limit 1 = 50% load limit - 2/4 compressor units. Load Limit 1 = 66% load limit - 3/6 compressor units. Load Limit 2 = 33 % - 3/6 compressor units only.

Change Schedule

The daily schedule is a 1 week schedule and must be programmed for the start and stop time for each week day and a holiday if desired. A box is provided to specify which days are to use the holiday schedule.

Programming the same time for both Start and Stop times will cause the display to enter 00.00 for both times which will cause the chiller to always be allowed to run.

Repeat Monday

The other days can be selected to change to the Monday schedule.

Clear Schedule

In a situation where it is required to run the chiller 24 hours a day, 7 days a week, the Chiller Control panel should first have its entire Daily Schedule zeroed (00.00) for all Start and Stop times. This puts the chiller in the run mode at all times. The OptiView Remote Control Center may now be programmed with all zeroes (00.00) for all Start and Stop times by pressing the Clear Schedule button. Since the chiller panel is already in the run mode, programming the OptiView Remote Control Center for all zeroes will keep the chiller in this mode indefinitely, allowing the chiller to run whenever demand requires.

The system is equipped with a high-efficiency air handler that enhances airflow, ensuring that every corner of the space benefits from consistent temperature control. Its unique design facilitates quiet operation, making it ideal for residential spaces where noise levels need to be kept to a minimum. This whisper-quiet functioning doesn’t compromise power, as the air handler is designed to work collaboratively with the compressor to deliver efficient cooling or heating throughout the home.

York has integrated smart technology into the 00497VIP, allowing homeowners to control the system remotely via smartphone applications. This feature not only adds convenience but also enables users to monitor energy usage and adjust settings from anywhere, enhancing the possibility of energy savings.

The system also boasts advanced filtration capabilities, utilizing a multi-stage filtration system to capture dust, allergens, and other airborne particles. This technology improves indoor air quality, promoting a healthier living environment.

In terms of adaptability, the York 00497VIP is compatible with a range of smart home systems, seamlessly integrating into existing setups. This flexibility extends to its installation, as it can be tailored to fit various spaces without significant modifications to the existing infrastructure.
