Abstract

PURPOSE: To prevent an abnormal operation of a program timer when it has been erroneously set, by checking the order of on-time and off-time immediately after the setting of program has been completed, and keeping the program timer from being actuated as a timer when the on-time and off-time are not alternately set.
CONSTITUTION: Timer setting instants T1, T2, T3, T4 are memorized in RAM in a micro-computer. After the checking of on-time and off-time has been started, T0=00:00 is initially set in RAM, and the contents of T0 are counted up every one minute until T0 has agreed with any of T1WT4. When the time of agreement is on-time, a flag ON in RAM is set, and, when the time of agreement is off-time, the flag ON is reset. The contents of T0 are further counted up to check the same as to whether T0 agrees with the remaining timer setting instants. When the present on- time and off-time are the same previous ones, "error" is displayed, and when they are different from each other, the checking of on-time and off-time is continued.
