Icon Function Screen Text Purpose
System Status Will start soon
A ve minute safety delay prevents the compressor
from operating too soon after shut-down to allow in-
ternal pressures to equalize.
This delay icon will also appear when immediate-
ly changing demand. For example immediately
changing from cooling to heating (gas, electric or
heat pump heating).
System Status Ambient lockout
This indicates that either the outdoor temperature is
above or below the balance point temperature set-
tings. The low balance point setting prevents heat
pump heating below the set point and back up heat
will be used. Typically the default is 25°F (-4.0°C),
but that setting can be adjusted by your dealer. At
25°F (-4.0°C) or below for example, only auxiliary
heating (electric or gas) is used.
If the high balance point is set to 50°F (10°C ) for ex-
ample, which is also adjustable by your dealer, then
auxiliary heat will not be allowed. Only heat pump
heating will be used. Anytime the outdoor tempera-
ture is below or above the balance point tempera-
ture settings, the ambient lockout notice will appear
on the home screen.
