BACKUP
FLAT BOTTOM
This control was developed by Pitco to replace bulb and capillary thermostats in fryer
applications. It utilizes the latest in microprocessor technology and allows a host of features
not practical with a simple capillary t-stat. Features include a selectable start up melt cycle,
drain valve interlock, faulty probe detection, and a boil out mode.
This manual details the operation and adjustment of the Solid State Temperature Control.

Operation:
2.1 Turn the appliance ON:
Place the melt switch in the desired position, typically Melt
. No melt may
also be selected only if vat is filled with liquid cooking oil. Turn the control ON by
pressing the rocker switch to the “1” position. The green power indicator will
illuminate.
2.2 To turn the appliance OFF:
Turn the control OFF by pressing the rocker switch to the “O” position. The green
power indicator will go out.
2.3 To Set the Cooking Temperature:
Adjust the temperature set knob to the desired cooking temperature.
2.4 To Perform a Boil Out operation:
Normal maintenance of a fryer requires regular tank cleaning. This
process involves draining the vat of oil and filling with water.
Cleaning solution is added, and the control is set to boil by the
following method:
‰
‰
Start with control in the OFF condition.
Toggle the on/off switch in the following sequence- ON – OFF –
ON – OFF – then ON. This sequence must be performed within 3
seconds.
HFB indicator flashes every ½ second
when in Boil Out mode.
‰
The power and heat demand indicators will turn on. The heat
feed back indicator flash continuously to confirm boil mode.
To exit boil mode, turn the control Off.
2.5 Drain Valve Interlock:
This control monitors the closed condition of the drain valve. If the
valve is detected open, the control assumes the vat has been drained
and heating control is suspended. The heat feed back indicator will
flash 7 times, pause, and repeat. To reset the drain interlock:
‰
‰
‰
‰
Close the drain valve.
Turn the control OFF.
Refill the vat with oil.
Turn the control ON.
HFB indicator flashes 7 times, pauses,
then repeats, until the drain valve is
closed.

Fault Detection
3
3.1 High Limit Trip or “Heat Failure”:
This control monitors the appliance response to heat demand signals.
Under normal conditions the heat feed back indicator follows the heat
demand indicator. When the appliance fails to respond, the heat feed
back indicator will remain off. Typical causes are:
‰
‰
High Limit device is tripped and needs to be reset.
On gas appliances, a substandard pilot flame, or ignition module
problem may be indicated.
‰
For electric appliances, an open line fuse may be indicated.
Normal operation when HFB indicator
follows Heat Demand.
Heat Demand without Heat Feed Back
is a Fault indication.
3.2 Open or Shorted Probe:
This control continually monitors the condition of the thermal sensing
probe. If this probe is detected out of range (open or shorted), heat
control activities are suspended. The heat feed back indicator will
flash 3 times, pause, and repeat.
This condition requires repair of the probe, or related wiring.
HFB indicator flashes 3 times, pauses,
then repeats.

Field Calibration
If field calibration is deemed necessary, follow these
steps:
‰
Allow appliance to heat to set point, and allow 30
minutes to stabilize.
‰
Measure the vat center oil temperature.
Compare this with the knob pointer scale.
‰
‰
‰
‰
To reposition the knob, pry off the cap of the knob with a sharp knife blade.
Without turning the shaft, loosen the 5/16-compression nut. Pull the knob off.
Re-install the knob with the pointer at the temperature indicated on the test thermometer.
Tighten the 5/16-compression nut, and install cap.
