Both ISU 301 Control Options must be set to Advanced to
view or adjust this ISU.
This ISU is only displayed when the thermostat is set
to 2 cool stages.
The indoor temperature must rise to the selected
differential setting before the thermostat turns on
the stage of cooling. For example, if stage 2 is set to
2° F (1.0° C), the indoor temperature must be 2° F
(1.0° C) away from the setpoint before stage 2 turns
on. When set to Comfort, the thermostat uses the
stage of cooling as needed to keep the indoor
temperature within 1° F (0.5° C) degree of the
setpoint.
Commercial ISU 301 Control Options must be set to Advanced to
view or adjust this ISU.
This ISU is only displayed when the thermostat is set
to 3 cool stages.
The indoor temperature must rise to the selected
differential setting before the thermostat turns on
the stage of cooling. For example, if stage 3 is set to
2° F (1.0° C), the indoor temperature must be 2° F
(1.0° C) away from the setpoint before stage 3 turns
on. When set to Comfort, the thermostat uses the
stage of cooling as needed to keep the indoor
temperature within 1° F (0.5° C) degree of the
setpoint.
Both ISU 301 Control Options must be set to Advanced to
view or adjust this ISU.
This ISU is only displayed for conventional systems
that have 2 heat stages.
The indoor temperature must drop to the selected
differential setting before the thermostat will turn on
the stage of heating. For example, if stage 2 is set to
2° F (1.0° C), the indoor temperature must be 2° F
(1.0° C) away from the setpoint before stage 2 turns
on. When set to Comfort, the thermostat will use the
stage of heating as needed to keep the indoor
temperature within 1° F (0.5° C) degree of the
setpoint.
