INSTALLATION
RETURN SENSOR WIRING OPTIONAL (AVAILABLE IN HEATING ONLY)
• If the Return Sensor is connected, must be purchased separately, the SQ-Elite-8T will recognize
it and alternate its temperature on the display with the Target temperature. If the Return
temperature is below the Minimum Return, the SQ-Elite-8T will sequence stages based on the
Return Sensor, Minimum Return, Calculated Target, and the actual System Temperature.
• The Return on the SQ-Elite-8T is designed to be connected to a temperature sensor that can
be purchased separately (HT #904250–00) for immersion in a 3/8ID well (P/N 350147–00 or
P/N 904011–00).
• The sensor wires can be extended up to 500’ using shielded 2-conductor cable (Belden #8760
or equivalent (#18/2)).
• Temperature sensors have no polarity. Connect the wires from the outdoor sensor to the
SQ-Elite-8T terminals marked OUTDOOR TEMP - 31, 32.
• Connect the shield to the circled terminal 32 with one of the sensor wires. Do not connect it to
the sensor.
WIRING THE DOMESTIC HOT WATER (DHW) SENSOR
• The DHW input can be used to raise system Set Point to 200°F or Maximum Target, whichever
is lower. The DHW Piping on page 28 must be selected from the Startup Menu to determine
the DHW Priority options.
• DHW Call terminals can be connected to either a dry-contact or a temperature sensor that can
be purchased separately (HT #904250–00) for immersion in a 3/8ID well (P/N 350147–00
or P/N 904011–00).
• If using a dry contact, wire an aquastat or other controls to provide dry-contact closure on the
DHW terminals.
• If using a sensor, the sensor wires can be extended up to 500’ using shielded 2-conductor cable
(Belden #8760 or equivalent (#18/2)).
• Temperature sensors have no polarity. Connect the wires from the DHW sensor to the
SQ-Elite-8T terminals marked DHW - 33, 34. Connect the sensor shield to the circled
terminal 34 with one of the sensor wires. Do not connect the shield to the sensor.
• If Shutdown was selected as the External Input, any DHW call will be ignored when the
Shutdown is active.
WIRING THE SHUTDOWN
• This feature will only be available when Shutdown is selected as the External Input Mode
option from the Startup menu on page 29.
• This feature can be used whenever it is desirable to turn off the SQ-Elite-8T stage outputs from
a remote location or another controller (i.e. EMS input).
• When the Shutdown is enabled, all active stages will immediately turn off. The System Pump,
Combustion Air, and unit pumps’ or valves’ relays will remain energized for the Run-On delay
period and then turn off.
• The Shutdown signal must be a dry contact input. No voltage can be placed across the
SHUTDOWN terminals.
• Bring the two wires from the dry contact to the SHUTDOWN - 35, 36 terminals.
• When Shutdown is selected, Setback will be available using the programmed
Day/Night schedule.
