St-By CL
Stand-by cooling setpoint limit
Default value = 78 °F

The value of this parameter should reside between the occupied and unoccupied
cooling setpoints and make sure that the difference between the stand-by and
occupied value can be recovered in a timely fashion when movement is detected
in the zone.
Stand-by cooling setpoint range is: 54 to 100 °F ( 12.0 to 37.5 °C )

Unocc HT
Unoccupied heating setpoint
Default value = 62 °F

Unoccupied heating setpoint range is:
40 to 90 °F ( 4.5 to 32.0 °C )

Unocc CL
Unoccupied cooling setpoint limit
Default value = 80 °F

Unoccupied cooling setpoint range is:
54 to 100 °F ( 12.0 to 37.5 °C )

heat max
Maximum heating setpoint limit
Default value = 90 °F ( 32 °C )

Maximum occupied & unoccupied heating setpoint adjustment.
Heating setpoint range is:
40 to 90 °F ( 4.5 to 32.0 °C )

cool min
Minimum cooling setpoint limit
Default value = 54 °F ( 12 °C )

Minimum occupied & unoccupied cooling setpoint adjustment.
Cooling setpoint range is:
54 to 100 °F ( 12.0 to 37.5 °C )

Pband
Proportionnal band setting
Default is : 3

Adjust the proportional band used by the thermostat PI control loop.

Warning. Note that the default value of 3.0 °F ( 1.2 °C ) gives satisfactory
operation in most normal installation cases. The use of a superior proportional
band different than the factory one is normally warranted in applications where the
thermostat location is problematic and leads to unwanted cycling of the unit. A
typical example is a wall mounted unit where the thermostat is installed between
the return and supply air feeds and is directly influenced by the supply air stream
of the unit.

Set Type
Temporary setpoint enable
Default is : Permnent

Enables temporary setpoints
feature to any change of
occupied or unoccupied setpoint.

Temporar: (temporary) Local changes to the heating or cooling setpoints by the
user are temporary. They will remain effective for the duration specified by
ToccTime. Setpoints will revert back to their default value after internal timer
ToccTime expires.
To change setpoints permanently, revert to No this variable or write setpoints
through the network. Any setpoints written through the network will be permanent
ones and saved to EEPROM.
Permnent: (permanent) Any change of occupied or unoccupied setpoints through
the keypad by the user are permanent and saved to & EEPROM

Spt Func
Local setpoint settings
Default value = Dual Spt

Set the local setpoint interface for the user

Dual Spt ( Dual Occupied Setpoints Adjustment )
AttchSpt ( Single Occupied Setpoint Adjustment )

TOccTime
Temporary occupancy time
Default value = 2 hours

Temporary occupancy time with occupied mode setpoints when override function
is enabled
When the thermostat is in unoccupied mode, function is enabled with either the
menu or UI2 configured as remote override input.
Range is: 0,1, 2, 3, 4, 5, 6, 7, 8, 9, 10, & up to 24 hours
