INSTALLER MENU SEQUENCE
BOILER MINIMUM RETURN
When a return sensor is connected to the SQ-Elite-8T, it will monitor and control the boiler
return when in Heating mode. It does that by monitoring the Target temperature (TGT),
System temperature (SYS), Minimum Return, and actual return. (RTN). When the SQ-Elite-8T
foresees that a low return will occur, it will increase the Target automatically as an effort to
increase the return temperature. See Return Sensor Wiring on page 14.
MINIMUM RETURN
Adjustable Off, from 80ºF/27ºC to 140ºF/60ºC
Default:
120ºF/49ºC
Hold Button:
MENU/Min. Return
in Heating only
• The Minimum Return is the critical temperature at which the return should be above.
Normally, this setting is provided by the boiler manufacturer or the system engineer.
• The SQ-Elite-8T will use that value as a guide. It will start to add additional stages if it
foresees that the RTN temperature will drop below the Min. Return. During that period,
it will display “
Hold Return at 120
o
F
” in the Display Message Line to indicate
that the SQ-Elite-8T is sequencing boilers to protect the return from dropping below the
Minimum Return.
• Most condensing boilers will run more efficient with cooler return temperatures. In this
case, select the Of option on the Minimum Return to allow the monitoring of the return
on the display without sequencing the boiler stages.
RETURN LAG
Adjustable from 0 to 30 minutes Default: 2 minutes
Hold Button: MENU/Min. Return/Return Lag in Heating only
• It is the time it takes for the system return to change after sequencing the stages.
• Initially, adjust this value to equal the Reaction Time. Then, in extreme cold weather
monitor the return making sure it is about 10°F above the Minimum Return setting and
adjust it if needed.
SYSTEM SETTINGS
Hold Button: MENU/<System Settings>
The System Settings menu provides access to adjusting and fine-tuning the system for
enhanced comfort and better fuel savings. The SQ-Elite behaves differently based on the
selected Control Modes (See Startup Settings 27).
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.
