STARTUP SETTINGS

Can be accessed by holding down the Menu 
button for over three seconds. 

PROGRAM CHANGE SETTINGS

To be able to change the SQ-Elite settings the Program/Run Switch must be set to Program. 
The switch is located under the Enclosure Wiring Cover for security. The Enclosure Wiring 
Cover can be securely closed using a padlock.

STARTUP SEQUENCE

Hold Button:

 MENU/<System Startup>

• 

When powered, the SQ-Elite performs a self-test on its components. After the self-test 
diagnostics have been successfully completed, the SQ-Elite will initialize the panel.

• 

On the first power up, the System Startup screen will appear after the initialization is 
complete. If it doesn’t, the SQ-Elite has already been configured

• 

The System Startup menu sets the main parameters as the type of sensor, the type of 
output whether heating or cooling, the sequencing mode, and many other parameters 
described in this section.

• 

Before entering the Startup menu, several warnings will alert you to the consequences of 
making Startup changes.

CONTROL MODE

Outdoor Reset, Set Point, EMS 4–20mA 

Default:

 Outdoor Reset

Hold Button: 

MENU/<System Startup>/..../Control Mode

• 

Outdoor Reset provides a variable set point based on outdoor temperature. Available for 
Heating applications only.

• 

Outdoor Reset mode requires the use of an outdoor sensor. DO NOT select Outdoor 
Reset without an outdoor sensor.

• 

Set Point mode does not require an outdoor sensor. If an outdoor sensor is connected in 
Set Point mode it will be used only as an Outdoor Cutoff point. That is, to turn the stages, 
system, and Comb. Air relays off.

• 

The EMS 4–20mA allows the SQ-Elite-8T to receive an external set point from an EMS/
BMS system. This option requires the use of the 4–20mA EMS Interface (HT# 926741–00).

• 

You must select the 4mA (min) and 20 mA (max) Set Point values in the following screens.

• 

Connect the 4–20mA EMS Interface to the SQ-Elite-8T RS485 connection using the 
phone cable provided with the 4–20mA EMS interface.

DISPLAY UNIT

ºF, ºC 

Default:

 ºF

Hold Button: 

MENU/<System Startup>/..../Display Unit

• 

The SQ-Elite-8T can control boilers and chillers in hydronic environment where the 
temperature is the critical factor. It allows the user to display temperature information and 
settings in either ºF (Fahrenheit) or ºC (Celsius). Select the display unit that is best suited 
for your application.

 WARNING 

A good practice after 
performing any Startup 
menu modifications is to 
check all operating settings 
and adjustments to match 
the new settings.
