PROGRAMMABLE CONTROL FUNCTIONS
Off (Relay OFF Temperature) – Settable temperature
at which the controller will turn off the heating blanket.
Range: -40° to 212°F.
On (Relay ON Temperature) – Settable temperature at
which the controller will turn on the heating blanket.
Range: -40° to 212°F.
ASd – Anti-Short Cycle Delay – Preset to zero minutes,
this is the wait time before the controller does anything
after plugged in or after the power comes back on in
the case of a temporary power outage. For example,
ASd is useful when running a cooling pump where a
quick power outage or temperature cycle will stall the
compressor and it won't safely restart until the pressure
has equalized in the system, which can take several
minutes. For heaters, there is no reason to wait to restart
the system.
SF – Sensor Failure Operation – This is preset to zero,
which has the effect of turning off the heater in the
rare case of sensor failure. Set this to one if user wants
to run full power without temperature control if sensor
malfunctions.
F or C – Temperature Units – The units can be switched
from Fahrenheit to Celsius or back by pressing the UP
and DOWN arrows simultaneously.
To change the values of any of these variables (except
F or C), press and hold MENU until SP flashes on the
screen, then release MENU. The controller is now in the
programming mode. Use the UP or DOWN arrow to scroll
to the desired function. Push MENU again to show the
present value of that function. Use the arrow buttons
to select the new value, then press MENU again to
make that the new value in memory. If MENU key is not
pressed within 30 seconds, the controller will exit the
programming mode and the value will not be changed.
