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. 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 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.
