digital remote capabilities as well. Both of these remote control capabilities allow for the
standard Energy Management System (EMS) interface:
1. Remote Start
2. Remote Stop
3. Remote Leaving Chilled Liquid Temperature Setpoint adjustment (0 to 10VDC, 2 to
10VDC, 0 to 20mA or 4 to 20mA) or Pulse Width Modulation
4. Remote Current Limit Setpoint adjustment
5. (0 to 10VDC, 2 to 10VDC, 0 to 20mA or 4 to 20mA) or Pulse Width Modulation
6. Remote READY TO START Contacts
7. Safety Shutdown Contacts
8. Cycling Shutdown Contacts
