Showroom Mode

Showroom Mode was incorporated into the electronic control system so that units could be displayed in a showroom
setting. When in Showroom Mode, all cooling functions are disabled, but the lighting system and LCD remain
active.
To initiate Showroom Mode, the unit must first be switched OFF using the UNIT ON/OFF key (See Figure 3-14).
With the unit switched OFF, press and hold either pair of WARMER and COLDER keys, then press the UNIT
ON/OFF key, then release all three keys (See Figure 3-15).
To return unit to normal operating condition, repeat the steps above.
NOTE: Always recheck set-points after returning unit to normal operating condition.
NOTE: It is possible to determine if a unit is in Showroom Mode by initiating Diagnostic Mode. If "Sr" is observed in
the left temperature display area during Diagnostic Mode, the unit is in Showroom mode. Initiating Diagnostic Mode
is covered later in this section.
