• Check the 120VAC power input to the control Turn power to the control off and back on
• Make sure that the Green Ground Screw is connected to a reliable Earth Ground
• Make sure that all wiring is fed to the control through the bottom knockouts and that no voltage wiring is
running behind the control board
• If the sensor reads Open, short the sensor input terminals The display should read
Short If it does,
then the problem is with the sensor wiring If it doesn’t, then the control may be damaged
• If the sensor reads Short, remove the wires from the input terminals The display should read
Open If it
does, then the problem is with the sensor wiring If it doesn’t, the control may be damaged
• Remove the wires from the input terminals The display should change to read
Open If it doesn’t, the
Multi-MOD Platinum may be damaged
• Otherwise, take an ohm reading across the detached sensor wires The reading should correspond to
the Temperature Sensor Chart If the difference is within 5°F adjust the sensor trim See "System and
Outdoor Sensor Trim" on page 47 Otherwise, the sensor may be damaged

• Check the pressure range set in the System Startup If the reading is still not correct remove the wires
from input terminals S and + (A5 & A6) Check for DC voltage across the two terminals If voltage
between 5 and 36 is not present, the control may be damaged
• Connect the black sensor wire to terminal + (A6) Put an amp meter in series by connecting the meter's
(-) to the sensor's detached red wire, and connect the meter's (+) side to the S (A5) input terminal The
mA reading should correspond to the Pressure Sensor Chart If it doesn’t, the sensor may be damaged
