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"
