SQ-Elite-MV & SQ-Elite-EXT Installation Manual

MotorIzed ValVe control
• What makes the SQ-Elite-MV unique is its ability to control the sequencing of the boiler stages in addition to modulating a
floating motorized valve to achieve the desired building comfort. Thus, eliminating the need of having two controls each with its
own set of wiring and settings. I.e., the same outdoor sensor, shutdown input, and season setting is used for the boiler system loop
as well as the motorized valve secondary loop.
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-MV has three modes of
rotation: Manual, First-On-First-Off, or Timed Rotation. This option automatically rotates boilers every selected time period from
one hour to every 41 days (999 hours) .
setBack or day/nIgHt scHedulIng
Two Setback modes are available for the SQ-Elite:
• The Day/Night Scheduling provides an adjustable time-based schedule for the Setback.
• The External Input 1`Setback mode uses an external signal to switch the operation of the SEQ in and out of setback mode.
InstallatIon
Each of the SQ-Elite-MV or SQ-Elite-EXT consists of three primary enclosure
components.
• The Enclosure Display Module:
contains the display, buttons, LEDs
and electric wiring terminals. It has two screws to hold it to the base. A
program configuration switch, used to adjust SQ-Elite-MV settings, is
placed above the terminals. This switch is enclosed with the enclosure
wiring cover for security. Wiring terminals are of the plug-in type to ease
installation and removal.
• The Enclosure Base:
contains the holes to mount and hold the control
against the wall or any flat surface. All other enclosure components mount
on the base. The bottom section of the Enclosure Base contains the wiring
chamber with knockouts on the bottom to easy installation.
• The Enclosure Wiring Cover:
seals the wires from the external
environment. It has two screws to hold it the base and a hole to secure
a lock on the wiring enclosure. A plastic web that separates the wiring
chamber into high and low volt sections has been provided.
MountIng tHe enclosure
• Select a location near the equipment to be controlled.
• The surface should be flat, and be sufficiently wide and strong to hold the
SQ-Elite-MV or SQ-Elite-EXT.
• Keep the control away from extreme heat, cold, or humidity. Ambient
operating temperature is from 20 to 120°F.
• Remove the Enclosure Wiring Cover from the control enclosure by
removing the two bottom screws.
• Remove the Enclosure Display Module by removing the middle screws.
• Screw the Enclosure Base to the surface through the upper and lower
mounting holes on the back of the enclosure.
• Replace the Enclosure Display Module and replace the middle screws.
• Do not replace the enclosure wiring cover until all wiring is done.
• When purchasing a padlock for the enclosure, the maximum shank diameter
should not exceed ¼"
