Option 03 — Fahrenheit/Centigrade
Select between Fahrenheit (F) and Centigrade (C) operation. Factory default is
Fahrenheit (F).
Option 04 — Fan (G) On With W/W1
This selection determines whether fan (G) output is to be On or OFF when any
W/W1 (furnace or strip heat) output is On. Most furnaces and fan coils manage
their own blowers and do not require separate G signal. For these applications,
select OFF. Some auxiliary heaters require separate G signal to turn on blower. In
this case, select On. Select On for geothermal applications.
Default is OF (off).
Option 05 — Room Air Temperature Sensing (programmable models only)
The remote room sensor may be installed as a single sensor or multiple sensors may
be installed for further averaging functionality. See Fig. 17.
