Activation
17
(continued)
Caution: Remote activation can surprise an-
other technician working elsewhere on related
equipment. Communicate your intentions to
anyone else involved. For instance, when re-
motely activating the cooling stages of a sys-
tem; you don't want to start a fan or compres-
sor that someone may be inspecting.
5) Turn the Mode Switch to ACTIVATE.
6) Turn on component switches as appropri-
ate. Use care to activate components logically;
for instance, do not turn on BOTH a heating
and a cooling stage at the same time. Like-
wise, you usually turn on FAN when a
COOLing stage is active. Finally, respect the
sequence of stages; don't activate stage 2
(cooling or heating) unless stage 1 is active.
NOTE: Some systems may have other com-
ponents, like 'Emergency Heat' that you may
test. You can use any of the four 'stage' wires,
(HEAT 1 & 2, etc.) to test these components.
