Both Unlocked: User has access to all thermostat settings.
Partially Locked: User can modify only temperature
settings.
Fully Locked: User cannot modify any settings.
Both This ISU is only displayed if ISU 106 was configured
to Wired/Internet.
Select Yes if a wired indoor, outdoor, or discharge
sensor is wired to S1.
Both Select Yes if a wired indoor sensor is wired to S1.
Both Select Yes if a wired outdoor sensor is wired to S1.
Both Select Yes if a wired discharge sensor is wired to S1
Both Select a name (location) of the Wired Remote Indoor
Sensor.
Both Confirms type of sensor wired to S1.
Both Select 10K or 20K based on the sensor installed.
Refer to resistance values below:
C7189U1005 = 10K ohm
C7772 = 20K ohm
TR21 = 20K ohm
TR21-A = 10K ohm (IMPORTANT - the TR21-A must
be used in combination with a TR21 sensor or
another TR21-A sensor for the thermostat to
calculate the correct indoor temperature reading).
See "Wiring guide — Wired Indoor Sensors"
beginning on page 89 for information on the sensor
type you should select based on how the sensors are
wired. For example, you would select 20K when you
have two TR21-A (10K) sensors wired in series.
Both Only displayed when a wired indoor sensor is
configured. Select Yes if you want the thermostat to
average with wired indoor sensor. Select No if you
want to sense temperature only at the wired sensor.
Both Confirms type of sensor wired to S1.
Both Confirms type of sensor wired to S1.
Both Select 10K or 20K based on the sensor installed.
Refer to resistance values below:
50062329-001 = 10K ohm
32005180-002 = 10K ohm
C7735A1000 = 10K ohm
C7770A = 20K ohm
C7041 = 20K ohm
Both If an optional Discharge Sensor is used, this feature
can help prevent icing on the air conditioning A-Coil.
When temperature reaches the limit you set,
compressor(s) will shutoff while the system fan
continues to run, until the temperature rises to a safe
level.
