ELECTRONIC CONTROL TERMINOLOGY & COMPONENT DESCRIPTIONS

The appliances described in this manual utilize an electronic control system which monitors, regulates, controls and

displays a variety of functions and operations in the appliance.

The table below defines some of the basic electronic control system terminology.

Term/Component Definition / Description

Main Control Board ..……….… (Also referred to as the Main “Controller” Board), is the printed-circuit board (PC

Board) which contains a microprocessor, relays, triacs and electrical connections

that monitor and control all functions of the appliance.

Microprocessor ……….….…... An electrical component on the control board which receives electrical signals from

other components, processes the information, then sends electrical signals to relays

and triacs on the board to open or close, switching components in the appliance

ON or OFF.

Relay ……………………….…. An electrical component on the control board which switches other components in

the appliance ON or OFF when instructed to do so by the microprocessor.

Triac ……………………....…… Similar in function to a relay, the triac is a three terminal semiconductor for control-

ling current in either direction.

User Interface Module (UIM) .. (a.k.a. Control Panel or Key Pad), is that part of the electronic control system where

all manual input operations are performed, also where all icons, words and codes

are displayed

LCD (Liquid Crystal Display) ... A semi-liquid substance sandwiched between glass in the control panel assembly.

The molecules of this semi-liquid substance have no specific orientation. However,

when electricity is applied to them, they react predictably, aligning and straightening

in such a way as to control light passage. In doing so, they can be manipulated

and arranged to form the indicators that appear in the LCD.

Indicators .....………….………... The icons, numbers and words that appear at the LCD

Fault Codes (Error Codes) ........The code number indicators that appear on the LCD during diagnostic mode This

coded data represents current and/or historical problematic events that specific

electronic components may have experienced.

Display Units of Measure……... Temperatures displayed at the LCD may be in fahrenheit units of measure (°F) or

celsius units of measure (°C). A series of key strokes allows the temperature dis-

play units of measure to be switched to read as either °F or °C.

Set-Point ……………………….. The zone temperature, established by pressing the COLDER or WARMER keys.

High Offset (Cut-in)……….….....As the zone air temperature cycles up and down, the high offset is the maximum

zone temperature that the electronic control system will allow before calling for

cooling.

Low Offset (Cut-out)…….……... As the zone air temperature cycles up and down, the low offset is the minimum

zone air temperature that the electronic control system will allow before interrupting

cooling.

Thermistor....….......................... (a.k.a. a Temperature sensor) A resistor with which resistance changes as the tem-

perature around it changes. For electronic control system purposes, the micro-

processor measures this resistance and displays it as a temperature reading at the

LCD.

BASIC ELECTRONIC CONTROL SYSTEM

The electronic control system consists of high voltage and low voltage (See Figure 2-1 for High voltage Wire

Schematic and Low Voltage Wire Schematic for the models ID-30C/I and ID-36C/I).

Input operations for the electronic control system are performed at the control panel (UIM), with monitoring, regulat-

ing and controlling taking place at the control board. Temperatures and possible problems with the unit are dis-

played at the UIM depending on input commands given. The electronic control system is described in greater detail

on the following pages.

CONTROL BOARD LAYOUT AND SUMMARY TABLE

The electrical connection points on the control board are labeled alphanumerically. These labels correspond with

the alphanumeric control board summary table, located on the wiring diagrams. By referencing the summary table,

it is possible to identify which components are connected at which connection points on the control board. Below is

a layout diagram of the control board, and a copy of a summary table. (See Figures 2-2 and 2-3)

NOTE: All components on the control board are non-replaceable. If a problem with the control board is identified,

the complete control board must be replaced.
