Carrier RTU OPEN 11-808-427-01 - Manual (Page 44)

Start-up
38 RTU Open
• Use Power Exhaust Test to activate and deactivate the power exhaust (BO - 8) output.
• Use Economizer Test to set the (AO - 1) economizer output to any value from 0 to 100% of configured
output (2-10 Vdc or 4-20 mA).
• Analog Output 2 Test (AO - 2) is currently unused and does not require testing.
• Service Test mode does not timeout. Return all test variables to Disable or 0.00. Set Service Test to
Disable or cycle power to the RTU Open to return to normal operation.
Configuring the RTU Open's properties
To start up the RTU Open, you must configure certain points and properties. Appendix C is a complete list of
all the points and properties, with descriptions, defaults, and ranges. These properties affect the unit
operation and/or control. Review and understand the meaning and purpose of each property before changing
it.
