FIGURE 26: Heat Kit Configuration - Screen 1
If you select a 13 kW heat kit or larger, there are two available stages of
electric heat. You must select the amount of electric heat that is applied
during a first-stage (W1) heat call. During a second-stage (W2) heat call,
the entire amount of electric heat available is applied. For a first-stage
(W1) heat call, it is best practice to only use the appropriate amount of
heat required to temper the air during an outdoor unit defrost cycle.
