LonTalk Zone Sensor Installed:
1. Set ECTO 6.01 to option 3 (zone sensor system mode
with return air temperature back−up).
2. Set ECTO 6.17 to option 1 (continuous blower during
occupied).
3. Set ECTO 5.27 to option 2 (network zone sensor op-
tion).
IMC Settings:
1. Be sure the occupied 24 VAC input is energized by
adding a jumper wire between TB1−8 and 9. In the
event that communication is lost between the LonTalk
module and the IMC, the IMC will operate in the occu-
pied mode and use the occupied backup setpoints.
2. Change IMC UNIT ADDRESS DIP switch to 2 (see fig-
ure 7).
