TB7300 SERIES COMMUNICATING FAN COIL THERMOSTATS

Pband Proportional band setting
Default value = 3
Adjust the proportional band used by the thermostat PI control loop.
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 value = 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 and EEPROM.
Spt Func Local setpoint settings
Default value = Dual Spt
Set the local setpoint interface for the user.
Dual Spt (Dual Occupied Setpoints Adjustment)
Attch Spt (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, and up to 24 hours
Deadband Minimum deadband
Default value = 2.0 F (1.0 C)
Minimum deadband value between the heating and cooling
setpoints. If modified, it will be applied only when any of the setpoints
are modified.
Range is: 2, 3, 4 or 5 F, 1.0 F increments (1.0 to 2.5 C, 0.5 C
increments)
Cal RS Room temperature sensor
calibration
Default value = 0.0 F or C
Offset that can be added/subtracted to actual displayed room
temperature .
Range is: ± 5.0 F, 1.0 F increments (± 2.5 C, 0.5 C increments)
Cal RH Humidity sensor calibration
Default value = 0%RH
Offset that can be added/subtracted to actual displayed humidity by
± 15.0 %RH.
Range is : ± 15.0 %RH
