Installation
Power-Up Sequence
When the 1040 zone sensor is installed to the sub-base,
the zone sensor initiates a 90-120 second power-up
sequence. During the power-up sequence, the Screen
Calibration option is available for five seconds.
NOTE: Screen Calibration is available for five minutes if
the screen has never been calibrated.
If the screen is not pressed within five seconds, the
zone sensor will default to previously stored Screen
Calibration settings. The 1040 is factory calibrated and
can be recalibrated at any time by rebooting the zone
sensor.
NOTE: Temperature display may be inaccurate until
the 1040 zone sensor acclimates to ambient room
conditions, which may take up to one hour.
