Page 16: Temperature Monitoring And Control
TEMPERATURE MONITORING and CONTROL The clock is capable of monitoring and controlling temperature sensed by an external or internal probe (use function Fn27 to select control probe) . External probe can be located at a significant distance away. The system also stores Minimum and Maximum Temperature readings that can be displayed ON DEMAND. -
Page 17: Internal Control Relay
Internal CONTROL RELAY Presettable Timer/Counter operation, Programmable Thermostat and Temperature HIGH/LOW ALARM can activate internal Control Relays that can be used to switch external loads up to 10Amp/240VAC. The Relays have SPDT contacts with Arc- Free switching protection. For Programmable Thermostat only either Normally Open or Normally Closed SPST contacts are usually wired from both internal relays. - Page 18 Control Relay Operation in LOW/HIGH Temperature ALARM application Internal Relay can be controlled by Low/High Temperature Alarm ONLY when Function Fn 37 is NOT ENABLED. Internal Control Relay operates in two different modes depending upon the setting of Function Fn 18. 1.
