Vi,
This issue is due to the E27 Alarm Engine system firmware not meeting the min requirement for 0.15.007. The control needs to have a minimum firmware of E27CB 0.5.80 in order to utilize the official touchscreen release.
Here is a link to information on the firmware and updating: https://www.elkproducts.com/alarm-engine-support/ae-update-info/
Thanks,
Mike
