04 INSTALLATION INSTRUCTIONS
2 To connect a second Auxiliary temperature sensor:
a Run the sensor wires through a knockout located on the bottom of the ETS-LT Control Module enclosure.
NOTE: The sensor wires can be extended up to 500 feet (152.5 meters) using an 18 AWG shielded
2-conductor cable (Heat-Timer P/N 703001–01 or equivalent #18/2 cable).
b Connect the sensor wires to terminal 24 and 25 on the ETS-LT Control Module.
c Connect the shield to terminal 25 on the ETS-LT Control Module.
NOTE: Do not connect the shield at the sensor end.
3 To connect an Auxiliary switch:
a Run the switch wires through a knockout located on the bottom of the ETS-LT Control Module enclosure.
NOTE: The switch wires can be extended up to 500 feet (152.5 meters) using an 18 AWG shielded
2-conductor cable (Heat-Timer P/N 703001–01 or equivalent #18/2 cable).
b Connect the switch wires to terminal 22 and 23 on the ETS-LT Control Module.
4 To connect a second Auxiliary switch:
a Run the switch wires through a knockout located on the bottom of the ETS-LT Control Module enclosure.
NOTE: The switch wires can be extended up to 500 feet (152.5 meters) using an 18 AWG shielded
2-conductor cable (Heat-Timer P/N 703001–01 or equivalent #18/2 cable).
b Connect the switch wires to terminal 24 and 25 on the ETS-LT Control Module.
COMPLETING THE WIRING
1 After all wiring to the ETS-LT is complete, apply power to the ETS-LT.
2 Do not re-install the Enclosure wire cover at this point as access to the PROGRAM/RUN switch is needed for
programing of the ETS-LT module.
3 With power supplied to the ETS-LT, the power loss capacitor of the valve actuator requires about 2 minutes to
fully charge.
