Quick Start Guide for Equipment Touch and

LS-1628 Unit Controller, Standard 3.1.5 Program

Introduction

This start-up guide will guide you through the

necessary procedures to start-up the unit equipped

with an LS-1628 controller. Before turning on the

controller, be sure all wiring is completed and in

the proper location. All input connections (i.e. SAT

sensor) wire into the grey terminals located on the

bottom of the controller. All output connections

wire into the blue terminals located on top of the

controller. Refer to the wiring diagram included with

the unit for the connections specific to this unit.

If installing a zone or room sensor, wire to TB5

terminal blocks, these will be factory wired to the

controller’s Rnet port located on bottom-left of the

controller. Refer to the wiring diagram included with

the unit for the connections specific to this unit.

Figure 1: LS-1628 controller

Form Number: TPM54-SU2 (321) New Release

Issue Date: 2021-03-16

Figure 2: Equipment touch

The equipment touch will be prewired by the factory

and mounted to the electric panel.

The equipment touch 2 (EQ2) is powered by 24

VDC, a DC power supply is provided and wired

into the grey connector shown in Figure 2. The

green and white wires run to TB 5 Rnet + and Rnet -

connections.

Note: DO NOT CONNECT old equipment touch

(EQ1) or ET1 Kits to this connection, it could

damage the controller, EQ1 or ET1 tablet.

The controller can now be turned on by the switch

on the upper left-hand side of the controller.

Once turned on, the controller will go through

a built-in start-up diagnostic, which can take

approximately 10 seconds to complete. After this,

the sensors and controls will become fully available

and the EQ2 display will upload and configure the

display to show the Home screen.

Note: This takes about 5 minutes to complete.

If nothing is touched or pushed on the Home

screen for 5 minutes, the Standby screen will

appear as below.

Note: The EQ2 screen timeout is set to a

standard setting of 2 minutes, this can be

adjusted, see .

Figure 3: Start-up diagnostic

The Standby screen shows the program name,

version number, date of revision issue, and the

current operational condition/mode of the unit (i.e.

UNOCCUPIED/SCHEDULE is the initial condition).

Press the continue button on the keypad to go to

the Home screen.

Figure 4: Standy screen

Equipment touch notes

First thing to note is the new EQ2 operates just like

a tablet or smart phone, the screen has a timeout

setting (the standard setting is 2 minutes, but is

adjustable to 10 minutes), when not used for the

allotted time the screen will timeout and turn off,

to wake screen simply touch anywhere on screen.

This is a Touch screen device so you will touch the

objects for the links, changing parameters, and

even to scroll by use of the slide bars on the right or

bottom of the screen.

Note: When scrolling and touching the screen

the new EQ2 has a ZOOM function that will

activate if the screen is touched three (3) times

in rapid succession, to return to normal view,

tap 3 times again in rapid succession. All menu

items can be accessed by slide bar, holding an

arrow, or placing your finger on the slide and

moving it. If a line is too long a slide bar will

appear on the bottom of the screen.

Password enter screen

There are 3 levels of passwords used in the

program, User, Admin and Factory passwords. User

passwords are not used often as most of those

screens are for READ OUT sensors and unit data.

Most changes will require an ADMIN PASSWORD

because these are specific configuration and are not

meant to be changed unless authorization has been

given. Once an ADMIN password has been entered

ALL screens and buttons below that level will not

need a password to be re-entered unless it requires

a Factory password. Factory password protected

changes that must be performed by an authorize

service tech, please contact the manufacturer's

technical service representative if assistance is

required. The password will timeout after 5 min of

screen inactivity and need to be reentered, when

this happens you will be brought back to the Unit

Status screen.

Note: You will need to switch the keyboard

input to numbers to enter the password.

operation, and selectable options, such as adding

zone sensor and safety switches. For specific

operational information for this unit, refer to

the unit specific Sequence of Operations provided

separately.

The controller will be pre-configured from the

factory with the necessary options for the unit to

operate properly. However, some items may need

to be modified in the field as required. This can be

achieved in the field through the EQ2 display.

Unit status screen

From the Unit status screen, most of the status

screens can be accessed. Also, the alarm reset will

appear on the home screen if the controller is in an

alarm state. Once alarm is reset, the Reset Alarm

text will hide itself.

Quick Start Guide for Equipment Touch and LS-1628 Unit Controller, Standard 3.1.5 Program 3

Figure 6: Unit status screen

All screens will have the top two lines which includes

a home, previous, and an alarm link. These links

on the Unit Status screen are followed by the date

and time. The next line will have the operational

condition/mode of the unit. This screen will have

links depending on the options of the unit, such

as ECW (Energy Wheel), Econ (Economizer), EF

Fan (Exhaust Fan), HP1 and HP2 (Heat Pump)

not shown, see Sequence of Operation for specific

configuration. Below are two status screens.

You can use this screens to test your Sequence

of Operation on the unit. The Supply fan status

screen shows the supply fan (SF) status is turned

On and the UO9 light will be On. The SF_APS is the

feedback from the Air Proven Switch or a current

sensor. The SF MOD is the percentage output of

the VFD. Minimum is the lowest speed the SF can

run (default is 50% or 30 Hz.). The second screen is

for Cooling 1 status. On the left side of the screen

are different status points. C1 EN will light when

the ZAT is 1°F above the Clg1 EN SP. Y1 will light

when the compressor 1 command or UO10 is turned

On. CMP1 will light when the current sensor closes

for compressor 1. HPS1 and LPS1 should always

have the light on. FRZ1 will light when the DXLAT1

sensor is below 38°F. Clg Mode will be on, when

OAT is above 55°F and there is demand for cooling

or dehumidification. Min off and on are 5 minute

timers. When the compressor starts or stops it

must remain or be off for 5 minutes. They will start

at 5 minutes and count down. These timers meet

Copelands requirement of 6 starts an hour. There

are two of the status screens for this unit. The

rest of the status screen are similar by using the

Sequence of Operation, then you can check the status

of unit.
