STATUS LED:

 The status LED shows normal operation by flashing slowly.  If the Status LED is not flashing, check power/fuse. 

Two flashes indicate that the Equalizer run cycle is on.  Three flashes indicate that the Short cycle protection is on. 

 

SHORT CYCLE PROTECTION (SCP) DELAY.

  The control unit protects the compressor from short cycling by a 5 minute delay at 

the end of every compressor “run” cycle.  The Status LED will flash rapidly three times to indicate SCP delay is active.

Note:  There is a 2 Min Minimum 
Heat Run Time (MHRT).  If the 
Heat Call is terminated during this 
period, no Equalizer cycle will be 
started at the end of the call.   If 
the Heat Call last longer than the 
MHRT, but less than 8 Min, then 
an Equalizer cycle will be started 
at the end of the call.
