This menu option is offered if using the optional Remote Temperature Sensor
to monitor air temperature (see “Remote Temperature Sensor” on page 3-14).
NOTES:
• The Remote Temperature Sensor is of a negative temperature co-efficient
(NTC) thermistor design.
• Due to the effects of cable length and electronic component tolerances,
the air temperature measurement by the Remote Temperature Sensor
could have an error of ±0.5 °C.
The recorded temperature can be trimmed to match a another plant reading.
