Showroom Mode
Showroom Mode was incorporated into the 700-2 electronic control system so that Integrated 700-2 Series units
could be displayed in a showroom setting. When in Showroom Mode, all cooling functions are disabled, but the
lighting system remains active.
To initiate Showroom Mode, the unit must first be switched OFF using the UNIT ON/OFF key
With the unit switched OFF, press and hold the WARMER and COLDER keys, then press the UNIT ON/OFF key,
then release all three keys
To return unit to normal operating condition, repeat the steps above.
NOTE:
Always recheck set-points after returning unit to normal operating condition.
NOTE:
Unlike the 700-2 tall units, it is not possible to determine if a base unit is in Showroom Mode by initiating
Diagnostic Mode and looking for “Sr”.
- To determine if a 700BF/I-2 unit is in Showroom Mode, press the ICE key on the control panel and listen for the
relay on the control board to “click.” If a “click” is not heard, the unit is in Showroom Mode.
- To determine if a 700BR-2 unit is in Showroom Mode, open both drawers to warm the compartments, adjust set-
points to 34°F (1°C) and listen for the compressor and condenser fan to energize. Due to the three minute mini-
mum-off time, and depending on how cold the compartments are, this may take several minutes to verify.
