Standard Controls

Standard controls supplied with the unit include the human
interface (HI) panel with unit control module (UCM). 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. 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 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 self-contained unit is controlled by a microelectronic
control system that consists of a network of modules.

Modular Series self-contained unit is controlled by
microelectronic control system consisting 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.
