Staging
The heater elements are turned on in increments. Refer to Stag-
ing Table. In addition on heaters larger than 5KW, the heat can be
staged (1 st & 2nd) either through an indoor thermostat or by using
an outdoor thermostat. This satisfies staging requirements im-
posed by some electric utilities on heaters larger than 6 kilowatts.
A control signal (24V) from Wl on the Indoor T'stat to Wl on the
control board energizes the 1st stage of heat. A control signal
(24V) to W2 on the control board energizes the second stage of
electric heat. To turn ON both stages at the same time, using one
control signal, W1 and W2 are jumpered together.
Ifthe indoor thermostat does not have staging capabilities, acces-
sory electronic outdoor thermostats are available that wil! control
two stages of electric heat.
