Furnace, Heater & Brooder Settings - continued
If you have set the Heater to Curtains Interlock (refer to the Temperature Control Settings section) specify the
curtain (and ridge vent) groups here. When interlocking is enabled for heaters (and brooders and furnaces), and the
controller detects that the heater’s ON Temp has been reached, the heater will not turn on if the interlocked curtains
are open more than about one inch.

The controller will perform a simple calculation to get a rough estimate of the number of gallons used by the heating
devices based on the size of the heater and whether the heater has a pilot light. Enter the BTU size (in thousands) of
the heating unit. If the heating unit has a pilot light then set the "Has Pilot Light" setting to YES.
