Room Air Sampling Configuration Mode

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.

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:
