SETTING
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.
NOTE: Multiple heating stages or multiple cooling stages must exist to use this feature.
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.
NOTE: Multiple heating stages or multiple cooling stages must exist to use this feature.
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.)
AIR FILTER REMINDER—Sets a value that specifies the number of equipment run hours before a FILTER
REMINDER message is displayed on the home and dormant screen banners to remind the user to change the
indoor air filter.
No message is displayed to the user if the setting is OFF. Decrements to the timer occur each hour total equipment
runtime is accumulated. Minute counts within each hour are not stored in non-volatile memory, so a power reset
clears out the minutes within each hour of run time. The filter reset reminder hour timer value is stored in non-
volatile memory.

NOTE: If the REMOTE SENSOR is set to FLTR to detect a dirty filter, this setting is disabled and not available to
the installer.
OCCUPANCY OUTPUT—Select which output relay to use for the Occupancy Output. The choices only include
outputs that are not already assigned to another function.
The output that you select (Y3, O/B, or W2) is energized when in the occupied state and de-energized when in the
unoccupied state.
NOTE: The occupancy output option is not available if the Y3, O/B, and W2 relays are already being used for other
functions. The Y3 output is used for 3 stages of cooling, the humidifier, and the dehumidifier setting of Humidi-
MiZer™/Perfect Humidity™/Hot Gas Reheat. The O/B output is used for heat pump equipment, the humidifier, and
the dehumidifier setting of Humidi-MiZer™/Perfect Humidity™/Hot Gas Reheat. The W2 output is used for 2 stages
of heating, the humidifier, and the dehumidifier setting of Humidi-MiZer™/Perfect Humidity™/Hot Gas Reheat.
Any output that is already being used is not shown in the OCCUPANCY OUTPUT selections.
OCCUPANCY INPUT—Select what to do when a short on the remote temperature sensor is detected.
The OCC (occupied) setting changes the current heat and cool setpoints to the occupied setpoints for the current
time range for the maximum hold time when a short is detected on the remote temperature sensor for the duration
of 2 to 5 seconds.
The UNOCC (unoccupied) setting changes the current heat and cool setpoints to the unoccupied setpoints for the
current time range for the maximum hold time when a short is detected on the remote temperature sensor for the
duration of 2 to 5 seconds.
ANALOG INPUT—Allows the installer to specify that the sensor is connected to the Analog Input terminals (H and
C).
ANALOG INPUT SCALING—Specifies the type of electrical signal that is output by the remote sensor configured
for use in the ANALOG INPUT setting. This setting is not available if the ANALOG INPUT is set to NONE.
HUIDITY OFFSET—Set an offset to the displayed humidity. This functionality offers the end user the convenience
of matching the actual sensed humidity to a different perceived humidity or a different humidity measuring device.
HUMIDIFIER—Enables humidifier control functionality. When humidifier control is enabled, the humidifier is
energized if there is humidity demand and any heating equipment is energized.
The output (Y3, O/B or W2) is a 24 Vac output only (sourced from R) and must be isolated with a relay at the indoor
equipment if 120 Vac is needed to interface to a humidifier unit.
NOTE: Humidifier functionality is not available if HEATING STAGES is set to NONE.
