When the Power Switch is in the “em” position, the thermostat
is placed in the Emergency Heat mode. The compressor will not
operate in this mode and only auxiliary heat will be used.
When Emergency Heat is selected on a multi-stage system, both
stages of heat operate at the same time. So, the heating acts like
a single-stage system.
NOTE: Emergency Heat Mode is not an energy saving set-
ting, so use only when necessary.
