AUX HEAT LOCKOUT
—
Sets an outdoor temperature above which the
AUX HEAT
(
W1
and
W2
) outputs are not energized in
HEAT
mode.
If the selected mode is
EMERGENCY HEAT
, the auxiliary heat is allowed to turn on.
The auxiliary heat lockout is checked when there is sufficient demand to energize
W1
,
but the output has not been turned on. Once the output has been energized, it remains
energized until the demand algorithm no longer requires the capacity of the auxiliary
heat, regardless of the value of the outdoor air temperature.
NOTES
•
The
AUX HEAT LOCKOUT
functionality is not available (and is set to the
OFF
setting)
with the
OUTDOOR EQUIPMENT TYPE
of
NONE
or
AC
selected, because the
AUX
HEAT LOCKOUT
functionality needs HP heating to operate.
•
If the
REMOTE SENSOR
is set to something other than
ODT
, there is no outdoor air
temperature being provided by the server and
AUX HEAT LOCKOUT
is set to a
temperature, the message
OUTDOOR N/A
is displayed in the home and dormant
screen banners to indicate an outdoor sensor is required but there is no outdoor
temperature information available.
•
In a dual fuel unit, the auxiliary heat lockout temperature is set to a value less than
the heat pump lockout temperature. This is to prevent the condition where the range
of outdoor air temperatures between the auxiliary heat lockout and the heat pump
lockout temperature result in no equipment operation. Below the heat pump lockout
temperature, the air source attempts to turn on but the auxiliary heat lockout
temperature prevents it from doing so. If the auxiliary heat lockout temperature is
changed so that it is less than the heat pump lockout temperature, the heat pump
lockout temperature is set equal to auxiliary heat lockout temperature value. This
change to the heat pump lockout temperature is not visible to the user while the
auxiliary heat lockout temperature is being changed.
