Conditions. During this mode of operation, the Hold
LED will flash.
Note:
Under certain settings, an Auto
Defrost cycle may run at the end of this chill cycle just
before the Hold cycle begins. During Hold mode , the
display reading will default to Air Temperature. Once
every minute, this reading will be briefly interrupted by
the message “HOLd” for two seconds followed by an
indication of the “time since the end” (of the chill cycle)
for two seconds.
e. Depressing the Stop key at any time will cease
operation of the current mode and return the operation of
the controller back to the
Idle Mode .
f. During this mode, the Fan relay is on and the
Compressor Relay is activated “On” when the warmest
product temperature (or air temperature, if no product
probes detected) is above
Product Temperature Set Point
(PtSP) + Product On/Off
Differential (PdiF) and “Off” when the warmest product
temperature is below
Product Temperature Set Point
(PtSP) - Product On/Off Differential (PdiF).
iii. Manual Mode
1.
Can be manually selected by pressing the Mode key twice
(illuminating the Man LED), adjusting the time with the
Up/Down arrow keys and then started by pressing the Start key.
2.
Note: Manual Mode is the default mode if no product probes

indicating that it is in the Manual mode. The display will
then show the timer value and begin to count down.
b. The Manual Mode is a timed cycle that runs according
to either the
Manual Mode Timer Default (nntd)
preset
value, or the manually adjusted timer value before the
cycle was initiated.
c.
During timed operation, the Fan relay is on and the
Compressor Relay is activated “On” when Air
temperature is above
Air Temperature Set Point (AtSP) +
Air On/Off Differential (AdiF) and “Off” when Air
temperature is below Air Temperature Set Point (AtSP) -
Air On/Off Differential (AdiF).
d. Once the warmest probe reaches product set point
temperature, a ringing alarm will alert the user.
