Quoting the OP

" ..... home work space moved from a nice heated room into an
unfinished basement. The area is nominally 55 degrees F however
an area has been partitioned of so that a cheap plug in 1500/750
watt heater can easily raise it to an excess of 80 degrees F"

That's why I didn't understand the controller's 35F-45F range
