Selecting & using operating modes
Your Herschel Select XLS heater works most efficiently when it is set up to run
against a program controlled by the T-BT thermostat. This program will always
ensure your room reaches the temperature you want at the time you want it, each
day of the week.
Usually you will want to set up and run the unit in Program (PRG) mode. You can
always override the programmed set temperature to be higher or lower by using the
+ or – keys to change the temperature and the T-BT will maintain this override
temperature until the next programmed period starts (when the next programmed
temperature will be set).
Selecting Manual (MAN) mode allows you to set and maintain a constant
temperature that does not vary with the time of day.
There is also a Holiday (HOL) mode which allows you to save energy by setting a
lower temperature while you are away. The HOL mode has a day-counter feature
allowing you to set the number of days you are away.
Selecting the Operating Mode
To select Manual or Programming modes, press the PRG button until the mode you
require is shown at the top of the display.
Manual Mode
Select the Manual mode by clicking the PRG button until MAN is shown on the
display.
Use the + or – buttons to set the temperature you want the T-BT to maintain in the
room. Note that the T-BT will maintain this temperature 24 x 7 until you switch to
another mode.

The T-BT comes with the following
