selectIng tHe systeM Features
The SQ-Elite-8S has been designed with Steam heating as the primary purpose. With this in mind, many of the SQ-Elite-8S features can
be utilized to ease, enhance, and improve your system performance. Some of these features are listed in this section.
set poInt or eXternal 4-20Ma set poInt
•
The SQ-Elite-8S can control the System Pressure either by maintaining an adjustable Set Point or by using an optional 4-20mA EMS
Interface (HT# 926741-00). The SQ-Elite-8S can receive an external Set Point as a 4 - 20mA signal from an EMS system using the
4-20mA EMS Interface.
pId or oss control logIc
•
The SQ-Elite-8S's PID can be used for applications where system reaction is slow and requires a long period to achieve or measure
the results. However, OSS can be used for applications where the load changes frequently and the sequencing must match the load
and its immediate change.
nuMber oF stages
•
The SQ-Elite-8S can be configured to control up to eight stages. It can control up to 24 stages by adding a maximum of two SQ-
Elite-EXT Extension Panels, each with eight stages.
control coMbustIon aIr daMper
•
The Combustion Air Damper output can control the equipment while utilizing the PROVE input to check the status on the Combustion
Air Damper End Switch or any other device before any stage is energized.
autoMatIc rotatIon aMong boIlers
•
Rotating the lead boiler to be activated on a call for output promotes even wear on all boilers. The SQ-Elite-8S has three modes of
rotation: Manual, First-On-First-Off, or Timed Rotation. This option automatically rotates boilers every selected period from one
hour to every 41(999 hours) days.
setback or day/nIgHt scHedulIng
Two Setback modes are available for the SQ-Elite-8S:
•
The Day/Night Scheduling provides an adjustable time-based schedule for the Setback.
