The service status word is made up of 8 hexidecimal digits. To decode this word, convert each
digit into a 4-digit binary number in the same manner as the system status word, which is
described in Decoding system status words on page 70.
Each binary digit (bit) represents a ag that is either acve (state 1) or not acve (state 0). To
help decode the service status word, each bit is numbered (starng with 0 for the least
signicant to 31 for the most signicant) as shown in Decoding system status words on page
70. The meaning of each bit in the service status word is given in Flashing service codes on
page 69.

Note that the number of hours unl the next service is due is esmated by the controller based
on the operang condions of the pump and therefore may reduce at more or less than 1 hour
per hour. The dominant factor in extending controller life is reduced pump temperature.
