Installation information

Control Options

Units may be ordered with either conventional thermostat interface or IntelliPakTM Direct Digital Control (DDC). IntelliPakTM controls include a Human Interface (HI) panel with two line by forty

(40)character clear English display for easy operator interface to unit setup and control parameters. All basic setup parameters are preset from the factory.

Human Interface Panel

The HI is unit mounted and accessible without opening the unit’s front panel. It allows easy setpoint adjustment using the HI keypad. In addition, the HI displays all unit operating parameters and conditions in a clear language display, which can be configured for either English, French, or Spanish.

The optional remote human interface (RHI) will control up to four self-contained units, each containing an interprocessor communications bridge (IPCB). It has all the same features as the unit-mounted HI except for the service mode.

For more information on setpoint defaults and ranges and unit programming, see the IntelliPak Self-Contained Program- ming Guide, PKG-SVP01B-EN. A copy ships with each unit.

IntelliPakTM DDC Control

IntelliPakTM DDC Control provides “smart” unit control with safety features and control relays for pumps, dampers, etc. The Modular Series IntelliPak self- contained unit is controlled by a microelectronic control system that consists of a network of modules.These modules are referred to as unit control modules (UCM). In this manual, the acronym UCM refers to the entire control

system network.

These modules perform specific unit functions using proportional/integral control algorithms.They are mounted in the unit control panel and are factory wired to their respective internal compo- nents. Each module receives and interprets information from other unit modules, sensors, remote panels, and customer binary contacts to satisfy the applicable request; i.e., economizing, mechanical cooling, heating, ventilation. See the Operation section of this manual for a detailed description of each module’s function.

Optional Controls

Optional controls include a disconnect switch, dirty filter switch, water flow switch (water-cooled only), supply air temperature reset, or external setpoint inputs. Daytime heating is available on units with electric, steam, or hot water heat control options. Morning warmup operation is available on all units.

The static pressure probe, zone night heat/morning warmup, supply air temperature reset sensor options ship separate inside the unit control panel for field installation. For more detailed information on the unit control options, see the Owner’s section of this manual.

Unit Nameplate

The unit nameplate identifies the unit model number, appropriate service literature, and wiring diagram numbers. It is mounted on the left end of the unit control panel.
