    • Each schedule can store 11 distinct and totally different parameters
    • All schedules retained in memory with power off
    • It is NOT NECESSARY to program functions not required
  • Single contactor circuitry; Process control outputs
  • Additional Standard Features:
    • Priority Heat Select
    • Contactor Failed Detection (Circuit breaker with shunt trip, optional)
  • Control can be INTERFACED with external Programmable Logic Control (PLC); Advanced interfaces available
