• To be able to change the SQ-Elite-MV 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.
• To display the button functionality, press any of the four buttons below the display.
• To enter the Installer Menu, hold down the MENU Button for at least three seconds. The
Installer Menu have advanced settings in addition to the User Menu settings.

DO NOT turn power off to the
SQ-Elite-MV when in off-season
or season is over. If you do so,
the battery will run down and will
have to be replaced. Instead
switch to Summer or Winter.

• The SQ-Elite-MV will turn all boiler relays off when it is in Summer setting. In addition,
the motorized valve MOV Close relay will energize for six minutes to guarantee closure.
However, a DHW call will bring boilers back on if needed. The Message Display Line will
display
Summer
and
Valve Close
to show status.
• When in Winter, the SQ-Elite-MV will activate the System relays whenever the outdoor
temperature falls to or below the respective Outdoor Cutoff setting. In addition, it will begin
heating whenever the system temperature falls below the Set Point Temperature. No season
information will be displayed.
• When the Winter is over, it is a good practice to switch the SQ-Elite-MV Season setting to
Summer. This will allow DHW calls to operate the boilers when needed as well as preserve
the battery life.
seQ and MoV reset ratIo settIngs
Each of the boiler loop (SEQ) and motorized valve loop (MOV) has their own reset ratio
settings that can be configured independently from each other.

• The Reset Ratio determines how the System water temperature will vary with outside
temperature changes. With any of the ratios, the colder it becomes outside, the hotter the
temperature of the system water. (See Understanding Operation Concept on page
• With a 1.00 (OD):4.00 (SYS) ratio, the System water temperature (SYS) will increase
rapidly as the outside temperature falls, hitting the Maximum of 240°F at 35°F outside
temperature. With a 4.00 (OD):1.00 (SYS) ratio, the System water temperature (SYS) will
increase slowly as the outside temperature falls. Even at -30°F, the system water will only
be 125°F, and at 22°F outside, the system water will be 112°F. Such a low Reset Ratio
might be used with radiant floor heating applications.
• With most baseboard heating applications, a 1.00 (OD):1.00 (SYS) setting is a good place to
start. With a 1.00 (OD):1.00 (SYS) ratio, for every degree the outside temperature falls, the
system water temperature is increased one degree.
• If required:
Adjust the RESET RATIO in cold weather.
If the ambient building
temperatures are too cold in cold weather, move the ratio to a higher selection. That is,
if 1.00 (OD):1.00 (SYS) was initially selected, change the selection to 1.00 (OD):1.25 (SYS). If the building temperatures are
too warm in cold weather, move the ratio to a lower selection. That is, if 1.00 (OD):1.00 (SYS) was initially selected, change the
selection to 1.25 (OD):1.00 (SYS).
