START-UP PROCEDURES A. SEQUENCE OF OPERATION 1. When power is first applied to the control, the control display will read the outlet temperature. The control will initially run through a self-diagnostic routine and then go into its operating mode. If there is no call for heat, the System will go into an idle state. The circulator must be wired to incoming power to operate continuously. If there is a code FL in the dis play window, then either the circulator is not operating or there is a restriction in the piping system, rendering an inadequate flow. 2. The control then performs selected system diagnostic checks. If all checks are successfully passed, a pre-purge cycle is initiated (the blower will be on maximum speed). 3. When the actual temperature is below a set-point, minu...
