is tripped it will get quite hot. To
reset the breaker: Shut off power to
the panel. Find and repair the short.
Restore the 24VAC power.
Indoor Fan
Any zone can activate the indoor fan
Control
and only the dampers in zones calling
for continuous fan operation will open.
Continuous fan operation will only
occur when there are no active or
pending, heat or cool demands. A dip
switch is provided to enable automatic
fan operation in heat mode. Useful for
straight electric heat or hydronic heat
applications.
