T-BT Battery powered
wireless thermostat
Calibration
Calibration is a process to alter the temperature of the T-BT up or down in order to
align the unit with another thermostat.
The T-BT can be calibrated 5
°
C up or down from the default of 0 (no calibration). You
can calibrate in steps of 0.5
°
C.
Calibrating UP (i.e. +1
°
C etc) means the T-BT will display a higher temperature than
the present one being shown. Use this when you think the T-BT is under-reading
compared with another thermostat.
Calibrating DOWN (i.e. - 1
°
C etc) means the T-BT will display a lower temperature
than the present one being shown. Use this when you think the T-BT is over-reading
compared with another thermostat.
When adjusting the T-BT Time & Temperature settings using the SET button,
calibration is the final setting you can change. The default is 0. Use + or
–
keys to
adjust this figure up or down.
