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.

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.

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.

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.
