Or maybe not.

This site is sponsored by Trolex Corporation, the former owner of
Trol-A-Temp. In 1999 Honeywell Home and Building Control, now part of
Honeywell International acquired Trol-A-Temp from Trolex Corporation.
Honeywell does not provide support for the older Trol-A-Temp Zone
Control Products and Systems. Trolex Corporation still supplies
replacement motors and parts that can support these older Trol-A-Temp
Systems.

There is no relationship between Trolex Corporation and Honeywell, the
owner of the Trol-A-Temp trademark.
