| Aux Lockout |
Use this parameter to set an auxiliary heat
lockout temperature. If the outdoor ambient temperature is greater
than the temperature you set, the auxiliary heat outputs (W1 and W2)
are not energized. |
None |
None, 5°F to 55°F in 5°F increments |
| HP Lockout |
Use this parameter to set a heat pump lockout
temperature. If the outdoor air temperature is less than the
temperature you set, the heating cycle starts with the auxiliary
heat source. If the outdoor air temperature is equal to or greater
than the temperature you set, or you set this parameter to
None, the heating cycle starts with the
heat pump. |
None |
None, 5°F to 55°F in 5°F increments |
| Stage Delay |
Use this parameter to configure the minimum
amount of time that the current stage must be on before starting the
next stage. |
120 min |
2 min to 120 min |
| Defrost Temp |
Use this parameter to configure the defrost set
point. If necessary, increase the temperature for a more aggressive
defrost operation. |
70°F |
50°F to 80°F in 5°F increments |
| Demand Response |
Use this parameter to enable or disable the
demand response feature. |
Disabled |
Disabled, Enabled (NO), Enabled (NC) |
| Comf/Eff |
Use this parameter to configure how quickly the
compressor ramps up to meet the set point. |
Efficiency |
Comfort, Efficiency |
| Temp Sensor |
Use this parameter to configure the number of
temperature sensors installed. |

1, 2 |
| Float Switch |
If the UA connects to an AVV air handler or a
two-stage furnace control, use this parameter to activate an
optional condensate float switch (S1-ACS2). For a normally closed
(NC) switch, select Enabled Open. For a
normally open (NO) switch, select Enabled
Close. |
Disabled |
Disabled, Enabled Open, Enabled Close |
| Aux Switch |
If the UA connects to a two-stage furnace
control, use this parameter to configure the optional dry relay
contact supplied by the utility company. For a normally closed (NC)
switch, select Enabled Open. For a normally
open (NO) switch, select Enabled
Close. |
Disabled |
Disabled, Enabled Open, Enabled Close |
| Aux Switch: Ht |
If you enable the Aux
Switch parameter, use this parameter to configure
how the switch activation affects the heating equipment. |
Stage Down |
Stage Down, Shut Off Comp |
| Aux Switch: Cl |
If you enable the Aux
Switch parameter, use this parameter to configure
how the switch activation affects the cooling equipment. |
Stage Down |
Stage Down, Shut Off Comp |
| Ventilator |
If the UA connects to a ventilator accessory
control, use this parameter to configure the type of ventilation
device installed. |
None |
None, ERV, HRV, Generic |
| Vent Mode |
If you configure a ventilator device in the
Ventilator parameter, use this parameter
to configure how often the ventilation device is opened. |
Timed |
Timed, Off, Continuous |
| Vent Runtime |
If you set the Vent
Mode parameter to Timed, use this parameter to configure the
ventilator device runtime for each ventilator cycle. |
20 min |
5 min to 55 min in 5 min increments |
| Vent Cycle |
If you set the Vent Mode
parameter to Timed, use this parameter to
configure the ventilator cycle period. |
1 h |
1 h to 4 h |
| Vent Limits |
If you set the Ventilator
parameter to Generic and you set the
Vent Mode parameter to
Timed, use this parameter to configure if
a damper is installed for ventilation purposes. |
Disabled |
Disabled, Default, Manual |
| No Vent Above |
If you set the Vent Limits
parameter to Manual, ventilation is not
allowed if the outdoor temperature exceeds this setting. |
100°F |
95°F to 105°F in 5°F increments |
| Vent with Cool |
If you set the Vent Limits
parameter to Manual, ventilation is allowed
when a call for cooling occurs and the outdoor temperature is
between this setting and the setting for No Vent
Above. |
85°F |
85°F to 100°F in 5°F increments |
| Vent with Heat |
If you set the Vent Limits
parameter to Manual, ventilation is allowed
when a call for heating occurs and the outdoor temperature is
between this setting and the setting for No Vent
Below. |
10°F |
0°F to 40°F in 5°F increments |
| No Vent Below |
If you set Vent Limits to
Manual, ventilation is not allowed if the
outdoor temperature is below this setting. |
0°F |
-5°F to 5°F in 5°F increments |
