Q. What does test mode do to the operation of the unit?

A. Test Mode allows the service personnel to check the operation of the control in a timely manner. By momentarily shorting the test terminals or switches, the Control enters a 20-minute Test Mode period in which all time delays are sped up 15 times.


Q. How to retrieve fault code?

flash code 1.


Q. What is slow flash and fast flash?

Q. What is a CO fault?
