how do i set a ceiling dual sensor to where its always on ? i thought you would change the time delay to override but when i do that it wont save the setting, only lets me goto 30min on the delay.

Asked by: dwil6212
There are two ways that you can set the sensor so that it won't turn the lights off. 1. Set the sensitivity to 'Override', and SEND the change to the sensor (note: SAVE simply saves the change to the LMCT-100-2 configuration tool, but does not send it to the sensor). 2. Unbind the sensor from the load(s) you no longer wish for it to control.

As Uaual I am unable to connect with the software DefuSE software there is no info on how to use th BIM Model ifo provided

Asked by: Anonymous
Using the DfuSe Demo software, appropriate firmware, and a micro-USB cable, a user can update the firmware in the v2 (HW-6) LMCT -100. Be sure your micro USB cable has the data pair in it and is not simply a charging cable. If the update process is followed and the app does not display choices in the "Available DFU Devices" drop-down, the cable is the most likely cause.

Asked by: Barry
Hi Barry, Sorry, that LMCT-100 has been discontinued and replaced with the upgradable LMCT-100-2. If the remote does not have the USB port in the battery compartment, then no upgrade is available.

Trying to upgrade LMCT-100-2 from version 6.14 to current 6.29 Made it to the point where the file to upgrade is selected and the program says the file is in the incorrect format. It doesn't like the .hex file. How is it uploaded?

Asked by: Steve H
There is a problem with that HEX file and cannot be upgrade to the LMCT-100-2. A very lazy company!!!! https://legrand.webdamdb.com/directdownload.php?ti=44269428&tok=Ma3CbkORPkhMgEve/B9WyQRR

What is the toggleNT mode?

Asked by: Andy
ToggleNT is short for Toggle Non- Tracking By default, when the Type is Group, the Mode is set to ToggleNT. With this value, the button will toggle, but the LED will not track the actual settings of the loads. Additionally, the button will not track if another source such as a sensor turns the load ON. The reason for this is that the button can’t track the status of all loads in the group.
