Yes This ISU only applies to Cooling.
This ISU is only displayed when ISU 13015 Set
Advanced Diagnostic Options is set to Yes.
The thermostat monitors Delta T of the system
Yes
ONLY when the indoor temperature is within a
certain range. Set to No Limit to monitor Delta
T during all indoor temperature conditions.
Yes This ISU only applies to Cooling.

Yes
The thermostat monitors Delta T of the system
ONLY when the outdoor humidity is within a
certain range. Set to No Limit to monitor Delta
T during all outdoor humidity conditions.
Yes This ISU is only displayed if ISU 2010 Heating
Equipment Type is Air to Air Heat Pump.
Press the up/down arrows to set the maximum
time duration of a defrost cycle. Check the heat
pump documentation for the defrost cycle time.
Note: The diagnostic algorithm detects when
the system goes into defrost based on the
measured Delta T of the system. When the
thermostat detects this change in temperature,
the thermostat will not compare Delta T to the
Minimum and Maximum Delta T Fault Limits.
After the defrost cycle has ended, the
thermostat will resume monitoring Delta T of
the system.
