DISCHARGE AIR TEMP:
This field allows user to configure the source for discharge air
temperature input. The following options are available:
• None: Select this if discharge temperature sensor is not
connected. When this option is selected, the Enable
Heating DAT HiLimit and Enable Cooling DAT Low Limit in
Equip Control page are disabled.
• Remote: Select this option if a discharge air temperature
sensor is hardwired to the thermostat. The thermostat is
compatible with the C7770A1006, C7031B1033,
C7031C1031, and C7031J1050 (averaging) 20K NTC
temperature sensor elements (20Kohms at 77°F).
NOTE: The T7350A, 1H1C thermostat model does not sup-
port the discharge air temperature sensor.
OUTDOOR AIR TEMP:
This field allows user to configure the source for outdoor air
temperature input. The following options are available:
None: Select this if outdoor air temperature sensor is not
connected. When this option is selected, the Enable Heating
OAT Lockout and Enable Cooling OAT Lockout options in
Equip Control page, cool and heat OAT @Min Ramp and OAT
@Min Ramp fields in Setpoints page are disabled.
Remote: Select this option if an outdoor air temperature
sensor is hardwired to the thermostat. The thermostat is
compatible with the following Honeywell outdoor air sensors:
C7170A1002, C7089A1002 PT3000 PTC temperature sensor
element (3484 ohms at 77°F).
NOTE:
1. In cases where an outdoor air temperature sensor
is hardwired, a valid value on Outdoor Tempera-
ture In point will take the precedence over the
hardwired input.
2. The T7350A, 1H1C thermostat model does not
support the outdoor air temperature sensor.
OCCUPANCY SENSOR:
This field allows user to configure the source for occupancy
input. The following options are available:
• None: Select this if an occupancy sensor is not connected.
• Remote: Select this option if an occupancy sensor is
hardwired to the thermostat.
NOTE:
1. In cases where an occupancy sensor is hard-
wired, a valid value on Occupancy Sensor In point
will take precedence over the hardwired input.
2. The T7350A, 1H1C and T7350B, 2H2C thermo-
stat models does not support the occupancy sen-
sor.
DAYLIGHT SAVINGS:
This option allows user to configure the settings for daylight
savings. The following is a description for each field:
Enable Daylight Savings: By default, this option is enabled.
Disable this option if the daylight savings feature is not
required for the thermostat. Unselecting this option will disable
the Start Month, Stop Month, Start Day and Stop Day fields.
Start Month: This field is available for configuration only if the
'Enable Daylight Savings' option field is selected. Its default value
is March. Change this option according to the daylight savings
settings in the country where the thermostat is installed.
Start Day: This field is available for configuration only if the
'Enable Daylight Savings' option field is selected. Its default value
is SECOND_SUN. Change this option according to the daylight
savings settings in the country where the thermostat is installed.
End Month: This field is available for configuration only if the
'Enable Daylight Savings' option field is selected. Its default value
is November. Change this option according to the daylight savings
settings in the country where the thermostat is installed.
Start Day: This field is available for configuration only if the
'Enable Daylight Savings' option field is selected. Its default value
is FIRST_SUN. Change this option according to the daylight
savings settings in the country where the thermostat is installed.
CONFIGURATION ID:
When this button is clicked, the button label is replaced by a
16 character alphanumeric number/code with every 2 digits
separated by a period. This code represents the configuration
information that define the equipment that is connected to the
thermostat. This code can be entered through the thermostat
keypad using the installer configuration (press Run/Copy
buttons simultaneously and navigate to the code. The user is
presented with a number identified by C1. Enter the first 2
digits of the configuration ID that TStatSpec™ has generated.
Continue entering 2 digits each for C2 to C8. Save this code
using Run button). The configuration in the thermostat is
changed to that in TStatSpec™. The thermostat installer setup
allows the user to enter the configuration through the keypad.
When the 'Configuration ID' button is pressed TStatSpec
derives the configuration string that user can enter into the
thermostat through keypad. This way, the configuration in
thermostat is same as it is TStatSpec with respect to inputs,
outputs, setpoints, loop tuning parameters, energy
management parameters, bypass time.
