5.3.2 IGNITION MODULE LOCKOUT FUNCTIONS
The DynaMax HS Controller may lockout in either a manual
reset condition requiring pushing the reset button to recycle
the control for a CSD1 requirement or an automatic reset
condition. Pushing the “OK” with the control in a hard lockout
condition is the only way to reset the DynaMax HS
Controller. Turning the main power “OFF” and then “ON” or
cycling the thermostat will not reset a hard lockout condition.
Wait until the display has synchronized before pushing the
“OK” button to clear a manual reset condition.
The DynaMax HS Controller may proceed into a soft lockout
condition. The boiler will stay in the automatic reset state
until the fault is corrected and will automatically return to
normal operating state.
