room Air sampling
In the auto (cycling) fan mode Room
Air Sampling will automatically cycle the
fan on for a minimum of 60 seconds, with
the control in the satisfied state, to peri-
odically circulate room air. Room air strati-
fication is therefore minimized due to the
fan being off for long periods of time so
that the microprocessor may accurately
track room temperature.
Room air sampling must be selected
through the configuration mode. Select-
able sampling times are: “OFF” (disabled),
5 min, 10 min, and 15 min.
Configuration Mode
While the unit is in the Off mode,
pressing the “MODE” and “PROG” but-
tons simultaneously for 10 seconds will
enter the Configuration mode. While in
Configuration mode, pressing the MODE”
and “PROG” buttons simultaneously
again or left idle for 20 seconds, will save
the new settings and exit the Configura-
tion mode.
The following table specifies the user se-
lectable settings in the Configuration mode:
