TEMPERATURE RISE

COMFORT/EFFICIENCY SELECT:
One dipswitch SW18 is provided to allow for selection be-
tween Comfort and Efficiency mode as follows:
SW18 = OFF = Comfort Mode, Target Temp Rise = +10°F
above Nameplate Mid-Rise
SW18 = ON = Efficiency Mode, Target Temp Rise = Mid-
rise as specified on Nameplate Label
Further, for communicating systems, the above selection
(made with dipswitch SW18 in legacy mode) can be made
GAS HEAT RISE AIRFLOW ADJUSTMENTS:
via the Econet control center.
