Terminating a Defrost Cycle
The defrost cycle terminates automatically when
the coil temperature is greater than or equal to 52
F (11 C) or the defrost timer expires. Defrost can
also be terminated by turning the unit off and back
on.
Selecting High Speed Lockout
Mode (If Enabled)
High speed operation can be locked out in noise
sensitive areas if required.
NOTE: High Speed Lockout Enable must be set
to [Enabled] in the Guarded
Access/Programmable Features Menu or this
feature will not be available.
IMPORTANT: HIGH SPEED LOCKOUT
TIMEOUT: If High Speed Lockout Mode is
selected, the High Speed Inhibit Timeout feature
may be set to return the unit to normal operation
after a set time period has expired. This prevents
extended operation with high speed operation
locked out. The time period may be from 15
minutes to 2 hours. If the time period is set and is
exceeded the unit will return to normal
operation, with high speed operation allowed. If
this occurs, the message HIGH SPEED
LOCKOUT ACTIVE at the top of the display will
disappear. If necessary to return to High Speed
Lockout Mode, press the High Speed Lockout
Key again.
The High Speed Lockout Key is a toggle. If high
speed is currently allowed, then pressing the High
Speed Lockout Key will disable high speed
operation. Pressing the High Speed Lockout Key
again will allow high speed operation. To change
the setting, press the High Speed Lockout key as
shown below.
