Unit installation

General Data
10 SCXF-SVX01K-EN
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
Programming Guide, PKG-SVP01*-EN. A copy ships with
each unit.
Unit Control Module
The UCM provides “smart” unit control with safety
features and control relays for pumps, dampers, etc.The
Signature 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 components. 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 Owner’s 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 warm-up operation is
available on all units.
The static pressure probe, zone night heat/morning warm-
up, 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.
