Fetco CBS-31P Technical Bulletin

TECHNICAL
BULLETIN
Subject: Thermostat – Pour-Over Brewers
Applies to: CBS-31P & CBS-31Pap Coffee Brewers
This bulletin supersedes Technical Bulletin 15.
The analog thermostat used in models CBS-31P and CBS-31Pap pour-over coffee
brewers has been replaced by a new digital thermostat. The new thermostat operates the
same way as the digital thermostat introduced in Technical Bulletin 14 for several other
models. However, these two digital thermostats are not interchangeable.
The new thermostat is interchangeable with the old style analog thermostat, so it can be
used as a replacement part in existing equipment. Please note that the LOAD and L1
terminals are in different positions on the new thermostat.
The new thermostat has two temperature probe connections. The blue screw-terminal
connection will accept the 2-wire analog temp probe that has been used for many years.
The white socket will accept the plug on the new style digital temp probe.

Thermostat range: 177° F to 208° F.
When power to the brewer is turned on, the readout will display either "An" (analog), or "dI"
(digital), for 2 seconds to indicate which type of temp probe is installed. Next, the readout
will flash and display the last two digits of the temperature setting for 3 seconds. (Due to
space limitations, the readout shows only the last two digits.)
During normal operation, the digital readout displays the last two digits of the actual water
temperature. When the adjustment tool is turned, the readout begins flashing to indicate
the set point, instead of the actual temperature. After the adjustment tool is released, the
readout stops flashing and displays the actual temperature again.
The dots below the numbers indicate the displayed temperature range.
Examples:
0 dots – less than 100° F
1 dot – 100° to 200° F
2 dots – over 200° F
A red LED lights when the power to the thermostat is on. A yellow LED lights when the
thermostat is calling for heat.
