3. If the unit has two contactors, with the unit ON and calling for heat and two decimals lit,

check for 240VAC between pin 1 (white wire) and pin 3 (red wire) of the J5 connector

on the T1000 control board. If no voltage is present, replace the control board (T1000). If

voltage is present, check for voltage across the contactor coil. If voltage is present at the

contactor coil, replace the magnetic contactor. If no voltage is present, verify that the

booster heater is wired according to the proper wiring schematic for the unit.

P65 PROBE TROUBLESHOOTING

1. Unplug and reseat the P65 probe wire in the jack on the T1000 control board. Note that

the error m

essage “ Err, No, Prb” will be displayed and the reset button mu

st be

pressed to clear the message.

2. If problem persists, unplug the P65 probe from the control board and plug into the RJ45

pigtail (not supplied).

3. If the problem

is with temperature control or high lim

it:

a. Change the configuration to ‘dSt’ to display the actual water temperature.

b. Check the temperature of the water with a thermometer and compare that with the

tem

perature on the display. If the two temp

eratures coincide, replace the T1000

control board. If the two tem

peratures do not

coincide, continue to the next step.

c. Unplug the P65 probe from the control board and plug into the RJ45 pigtail (not

supplied). Check the resistance value (ohms) between the blue wire of the pigtail

(#1) and the red wire of the pigtail (#4). Compare the resistance value measure

with the chart below at the measured temperature of the water. If the two values

coincide, replace the T1000 control board. If the two values do not coincide,

replace the P65 sensor

4. If the problem is with low water:

a. Verify that the unit is filled with water.

b. Check for continuity between the yellow wire of the pigtail (#2) and ground. If

continuity exists, replace the T1000 control board. If no continuity exists, replace

the P65 sensor probe.
