RELAY STATUS
Relay status displays the current state of each relay. While

the compressor relay, however the condenser fan is
actually powered through a DC output and is independent
of the Cond relay. Condenser fan status can be viewed
through the “Output” service menu option.

2. Press Select .
3. Use Up and Down to scroll through available

RELAY TOGGLE
Relay toggle is used to manually switch the state of each
relay to test for proper operation. In addition to the AC
relays, DC outputs may also be toggled. Relay toggle can
also be used to force the unit into a particular state. For
example, to force a 3018 / 3045 into a cooling cycle
activate Comp, F1, and F3.
