INSTALLER MENU SEQUENCE
BOILER OUTPUT
None, Pump, Valve
Default:
None
Hold Button:
MENU/<System Startup>/..../Boiler Output
•
When None is selected, the SQ-Elite-8T will sequence multiple heating or cooling units
without any additional unit pumps or valves.
•
The Pump option allows the SQ-Elite-8T to control the cooling or heating unit stages in
addition to the unit pumps. The pump stage will run for the Run-On delay after the lower
stage of that unit has de-energized.
•
The Valve option functions similar to the pump option except that when all stages are off
and after the Run-On delay has elapsed, the Lead unit’s valve relay will remain energized
to allow for pump flow across the system. The lead unit’s valve will remain energized
until the Outdoor temperature rises above the Outdoor Cutoff or when the Shutdown or
Summer is activated.
TOTAL BOILERS
From 1 to 24
Default:
varies based on Burner Type and Boiler Output
Hold Button:
MENU/<System Startup>/..../Boiler Output
•
This option in combination with Burner Type and Boiler Output Startup options will
determine the total number of outputs the SQ-Elite will need to control.
•
If the total number of stages selected, including unit pumps or valves, is more than
the control and extension stages, the additional units containing these stages will
have
CE
as their status and will seize to operate.
STAGING
Multiple Outputs, Single Output
Default:
Multiple Outputs
Hold Button:
MENU/<System Startup>/..../Staging
•
Most units will require that the higher output stages be energized after the lower output
stages. These units will need to select the Multiple Output option. That means, both Low
and High Output stages must be energized to achieve the unit’s maximum output.
•
Some units require that when the higher output stages are required, the lower stages
must de-energize. To operate these units, the user must select the Single Output option.
SEQUENCE
Lo/Hi/Lo/Hi, Lo/Lo/Hi/H
Default:
Lo/Hi/Lo/Hi
Hold Button:
MENU/<System Startup>/..../Sequencing
•
Some units run more efficient when the lower stages are energized alone than with the
higher stages. These types of units should select Lo/Lo/Hi/Hi. Then, the SQ-Elite will
sequence the lower stages of all Automatic units before sequencing the higher stages.
•
For the rest of the unit types, the Lo/Hi/Lo/Hi should allow the staging of the lower stage
of the lead unit followed by the higher stage of the same unit. Then when more stages
are needed, it will fire the lower stage of the lag unit followed by the higher stage of the
lag unit.
