Reset Button - Rheem 325 II Series Service Instructions Manual

Reset Button

On the underside of the controller is a reset button.
The reset button may be used to cancel the start delay, or reset Fault 9. Fault 9 will not
disable all heating unless it has occurred 3 consecutive times however if Fault 9 has
occurred once, or twice consecutively, the reset button will reset the consecutive
occurrence count.
The reset button also clears any stored Fault Code from the controller memory.
The reset button does not function during System Start-Up or the Last Fault Code display
function, however may be used at all other stages of system operation.
To reset the system, press and hold the reset button until both LEDs come on
(approximately 2 seconds). After both LEDs come on, release the reset button. If the reset
button is held down for longer than 10 seconds, the reset will not occur.
When reset, the system returns to System Start-Up.
NOTES:
1. The refrigerant high pressure switch is manual reset and may also need to be reset
following the occurrence of Fault 9.
2. Resetting the compressor start delay prematurely after the compressor has been
operating may cause the compressor to trip out on its internal overload switch, if the
heat pump is operated. This is due to the compressor‟s inability to overcome the
residual pressure differential that will remain in the refrigeration system for a period
of time after the compressor has operated. The compressor‟s internal overload
switch will reset automatically, however the controller may detect Fault 9 prior to the
automatic reset occurring.
