After the "P" is selected (by releasing the push button) the
integrated control will start flashing the "P" on display for 90
seconds. If push button is pressed again and held during
that time, the control will start to display characters corre­
sponding to different variable speed furnace models for 3
seconds each. While the wanted character-model is dis­
played push button has to be released. Selected option will
flash display for 10 seconds and during that time push but­
ton has to be pressed and held for 5 seconds. Once control
accepts new setting it will store data in non-volatile memory
and reset itself. If 10 seconds expires or push button is held
less than 5 seconds, control will exit field test mode and go
into idle without changing programming the unit size.

that it does not recognize and the thermostat sends a the
device a message to be in soft disabling mode until proper­
ly configured. Two horizontal bars will display.
