the HEAT position, tire heating section of your home comfort
system will operate until room temperature is raised to the
level you have selected. Of course, the heating unit will have
to operate for longer periods to maintain a comfortable envi-
ronment on colder days and nights than on moderate ones.

will operate economically and dependably, Maintenance can
