There are two options available for humidification:
•
Indoor RH setpoint—this controls the humidifier based on the desired indoor humidity setpoint
(options from 10%–45%).
•
Frost Control setpoint--The control references the outdoor temperature and indoor environ-
ment to calculate the risk of frost or condensation on interior walls and windows. A scale of 0
to 10 allows for customized settings based on the insulation properties of the home. A higher
number may be selected for well insulated homes, whereas a lower number should be selected
on poorly insulated homes. A lower number should be utilized if condensation is observed.
There are two control options for enabling humidification:
•
Humidification with an active call for heat.
•
Humidification without an active call for heat (control energizes blower and humidifier).
Humidification is only available when in the heating mode (or in the auto mode when the last
call was for heating). A 60 second minimum blower off delay is enforced if "steam" humidifi-
cation is selected.
There are two categories for Installer Setup.
•
Standard—this is the basic system settings such as heat pump or cooling only, single or multi
stage, compressor type, etc. This is the basic system set up that is self discovered in communi-
cating mode, but requires manual input when using a Relay Panel for 24 volt configurations.
•
Advanced—this provides advanced configuration of the system such as cycles per hour, mini-
mum run times, humidification and dehumidification setpoints, blower delays and temperature
lockouts to name a few of the customizable features in this set up.
Load Value is a numerical representation of the needed capacity to satisfy the setpoint. Proportional
(distance from setpoint) error plus integral (time away from setpoint) error is used to calculate load
value.
System lockouts will disable a certain function of the system under specific outdoor temperatures:
•
Compressor Heating Lockout – will lockout all compressor operation below a set outdoor tem-
perature (from 5°–70°). This value must be set lower than the auxiliary heat lockout.
•
Auxiliary Heating Lockout – will lock out auxiliary heat stages above a set outdoor tempera-
ture (from 40°–70°). This value must be set higher than the compressor heating lockout.
•
Defrost Heater Balance Point for W1, W2 & W3 – will lock out specific auxiliary heat stages
when above a set outdoor temperature. (W1 setpoint is from 40°–55°, W2 & W3 setpoints are
from 5°–55°). This feature does not apply to dual fuel systems.
•
Compressor Cooling First Stage Lockout – will lock out the first stage compressor above a
set outdoor temperature. (from 80°–120°)
•
Compressor Heating First Stage Lockout – will lock out the first stage compressor below a
set outdoor temperature. (from 0°–50°)
•
Furnace First Stage Heating Lockout – will lock out first stage furnace operation below a set
outdoor temperature. (from 15°–50°)
First stage lockouts are not available with zoning.
Multiple 950 Controls that manage individual systems can be linked. Multiple systems can be man-
aged from any control location. A wireless home network is required for multi system functionality.
Reminders can be set for filters, UV lamps, humidifier pads, and various other service reminders.
There are three levels of restore:
•
Restore from the Setting Screen – this restores all personal configurations, such as program
schedules and home screen customization to their default setting.
•
Reset Advanced Options from the Install Set Up screen – this restores all the advanced set
up selections such as system lockouts, accessories, air flow and comfort options to their default
setting.
•
Restore Factory Defaults – this restores the control to its "out of the box" condition. All settings
will be set to their factory default condition.
The control has the ability to log all information to a SD Card. A typical 24 hour log will consist of 12
to 20 megabytes of information. The control will overwrite the oldest data once the card becomes full.
Security initiates a keypad lockout. The control can only be accessed by a four digit pass code which
can be configured in two different formats:
Pin Lock: When the Pin Lock is selected, the control is completely locked. The user will need to
enter a four digit password to change any setting (the default is "1234").
Guest mode: The enabling of this mode allows a guest to change the temperature up to 5° in either
direction from setpoint and access to the weather, but cannot change the mode or any customized
settings. Note: The back door password is 9467.
