INSTALLATION
WIRING
WIRING THE POWER
• Bring the 120VAC 60Hz power wires through the bottom Knockout of the enclosure.
• Class 1 voltage wiring must enter the enclosure through a different opening from any
Class 2 voltage wiring.
• Connect the hot line to the terminal marked L.
• Connect the neutral line to the terminal marked N.
WIRING THE SENSORS
SYSTEM TEMPERATURE SENSOR WIRING
• The SQ-Elite is designed to be connected to a temperature sensor (P/N 904220–00) for
immersion in a 3/8 ID well (P/N 350147–00 or P/N 904011–00) located on the common header.
Contact the factory for additional temperature sensor options.
• Temperature sensor wires can be extended up to 500’ by splicing shielded 2-conductor cable
(Belden #8760 or equivalent (#18/2)).
• Temperature sensors have no polarity. Connect the two wires from the sensor to the SQ-Elite-8T
terminals marked SYSTEM TEMP 27, 28.
• Connect the shield to the circled terminal 28 with one of the sensor wires. Do not connect the
shield at the sensor end.
OUTDOOR SENSOR WIRING
• When Outdoor Reset is selected, the SQ-Elite-8T will vary the system target based on the
outdoor temperature.
• Whether in Set Point or Outdoor Reset modes, the outdoor sensor can be used as an Outdoor
Cutoff. In heating, the SQ-Elite-8T will disable all Boilers when the outdoor temperature is
above the adjustable Outdoor Cutoff temperature. However, in cooling it will disable the units
when the outdoor temperature is below the Outdoor Cutoff. This feature will automatically be
activated when an outdoor sensor is connected.
• For an outdoor sensor, use a Heat-Timer outdoor sensor (P/N 904220–00).
• 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 - 29, 30. Connect the shield to the circled
terminal 30 with one of the sensor wires. Do not connect the shield at the sensor end.
WARNING
Class 1 voltage wiring must enter the enclosure through a different opening from any class 2
voltage wiring. Heat-Timer recommends installing a surge suppressor on the power source to
the SQ-Elite.
WARNING
Connect the Temperature sensor shield at the control to the sensor terminal marked “o“.
Do not connect the Shield at the sensor end.
