Residual Cool
Default is 0 seconds. This is the time, in seconds,
that the fan runs after a call for cooling is satised in
order to deliver any residual cooling ability from the
coil and ductwork into the conditioned space. Op-
tions are 0, 30, 60, 90 and 120 seconds. Touch < to

Low and High Balance Points
These balance points are for heat pump systems
only with an outdoor sensor installed and enabled
plus a indoor unit setting enable. Either gas/oil or
electric will enable the balance point options in the
installer settings list.
1. When in heat mode and the outdoor
temperature is below the programmed Low
Balance Point, then heat pump heating is not
allowed and only backup heat will be used.
2. When in heat mode and the outdoor temperature
is above the programmed High Balance Point,
then heat pump heating is allowed and backup
heat will not be used.
3. When in heat mode and the outdoor
temperature is between the programmed Low
and High Balance Points, then heat pump
heating and backup heat can be used.
4. Options are enable or disable. Default for both
is disable. Once enabled, the following settings
are available.
5. Low Balance Point Default is 25°F. Adjustable
range is -40°F to 48°F.
6. High Balance Point Default is 50°F. Adjustable
range is -38°F to 75°F.
NOTE: The high balance point minimum range is
adjustable to within +2°F of the low balance
point setting. For example, if the low
balance point is set to 0°F, then the lowest
setting for the high balance point is 2°F.
Deadband
Default is 2°F. The deadband setting is the mini-
mum dierence between the cooling and heating
setpoints. This setting is used in cool/heat mode to
ensure smooth equipment operation. The deadband
is adjustable from 2 to 9°F. Use the + or - option to
select desired deadband. Touch < to return to pre-
vious menu.
Smooth Set Recovery(SSR)
Options are enable or disable. Default is Enabled.
When enabled, smooth set recovery begins recov-
ery up to two hours before the programmed time
so that the programmed temperature is reached at
the corresponding programmed event time. Assume
12°F per hour for rst stage gas/electric heating and
6°F per hour for rst stage compressor based heat-
ing or cooling. With Smooth Set Recovery disabled,
the control will start a recovery at the programmed
time.
