HP LOCKOUT—Sets an outdoor temperature below which the heat pump does not
operate. If set to OFF, the heating equipment cycle always starts with the heat pump,
regardless of the outdoor air temperature. If a lockout temperature is selected and the
outdoor air temperature is less than the selected temperature, the heating cycle is
started with the AUX HEAT SOURCE. If the outdoor air temperature is equal to or greater
than the selected temperature, the heating cycle is started with the heat pump. If the
outdoor temperature is not available, all heating cycles with compressor heat.
When the heat pump is not energized but there is demand sufficient to request heat
pump heating, the heat pump lockout temperature is checked against the outdoor air
temperature and if the outdoor air temperature is greater than the heat pump lockout
temperature the heat pump is energized. Once the heat pump is energized, it remains
energized until the heating demand no longer requires heat pump heating, regardless of
the outdoor air temperature.
NOTES
• The HP LOCKOUT functionality is not available if the OUTDOOR EQUIPMENT TYPE is
set to NONE or AC, because the AUX HEAT LOCKOUT functionality is only applicable
to heat pump systems.
• If the REMOTE SENSOR is set to something other than ODT, there is no outdoor air
temperature is provided by the server and the HP LOCKOUT is set to a temperature,
the message OUTDOOR N/A is displayed in the home screen and dormant screen
banners to indicate an outdoor sensor is required but there is no outdoor
temperature information available.
• Do not set the heat pump lockout temperature to a value greater than the auxiliary
heat lockout temperature unless the auxiliary heat lockout temperature setting is
OFF. This prevents 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 AUX heat
source attempts to turn on, but the auxiliary heat lockout temperature prevents it
from doing so. If the heat pump lockout temperature is changed so that it is greater
than the auxiliary heat lockout temperature, the auxiliary heat lockout temperature
value is set equal to the heat pump lockout temperature.

STAGE DELAY—Sets the minimum amount of time the current stage must be energized
before staging up to the next stage of capacity.

FORCED STAGE UP—Sets the maximum number of minutes that the equipment runs at
the current stage before forcing the equipment to stage up. The forced stage up occurs
even if the differential demand is not met.

DIFFERENTIAL—Sets a value that specifies the required difference between the current
space temperature and the setpoint that results in the equipment being energized to
satisfy the demand. This value is additive for each additional stage of equipment being
demanded.
(e.g. A chosen differential value of 0.5°F requires 0.5° difference between setpoint and
space temperature before first stage is turned on. Then a value of 1.0 degree of
difference between setpoint and space temperature before second stage is turned on.)
