CONTROL SYSTEM Microprocessor based. Program logic stored within non-volatile Flash EPROM memory. Set points and system configuration stored within EEPROM with at least 10 years storage life. Logged Data and time clock is stored on the memory chip with backup power. Menu driven controls with all operating sequences and control algorithms included. The control has non-volatile program memory and a capacitor backed clock in the event of power outage. All programmable options are installed via a "Yes" or "No" type question.
