A. HEATER ERROR CODE
An error code may occur in the installation of the heater. This condition may lead to a lock out condition of
the controller, which will need to be manually reset through the
{S4} button. These temporary codes will
help the installer correct the problem before going into a lock out condition, which will require a manual
reset.
B. HEATER ERROR
1. When an error condition occurs the controller will display an error code
on the display module.
2. These error codes and several suggested corrective actions are
included in Table 15.
C. HEATER FAULT
1. When a fault condition occurs the controller will illuminate the red
“fault” indication light and display a fault code in the format (Example:
|F00| ) on the display module.
2. Note the fault code and refer to Table 16 for an explanation of the fault
code along with several suggestions for corrective actions.
3. Press the reset key to clear the fault and resume operation. Be sure to
observe the operation of the unit to prevent a recurrence of the fault.
