Required Components (ordered separately):
24 VAC Transformer – The size of the transformer
needed is determined by the total power
requirements for the control panel, thermostats and
dampers. The control panel and thermostat together
require 10VA. The dampers require 10VA each. The
size of the transformer will depend on the greatest
number of dampers that could be energized at any
given time. NOTE – When using power close, spring
open dampers, at least one zone's dampers will not
be energized during a heating or cooling call.
