DIPSWITCHES FOR SELECTABLE OPERATION
Several operational characteristics of the EP113 programmer modules are determined by six (6)
dipswitches located on the side of the programmer. These characteristics include non-recycle/recycle
operation when the running interlock circuit (3-P) is opened (Dipswitch #1), interrupted or intermit-
tent operation of terminal 5 (Dipswitch #2), extended purge timing (Dipswitches #3, #4, #5), and
enable or disable the option that requires the 3-P running interlock circuit to be proven open at the
start of the operating cycle (Dipswitch #6).
WARNING: THE INAPPROPRIATE SELECTION OR APPLICATION OF A PROGRAM-
MER MODULE COULD RESULT IN AN UNSAFE CONDITION HAZARDOUS TO LIFE
AND PROPERTY. Changing the dipswitches modifies the operation of each programmer
module. Care should be taken to insure the proper dipswitch settings. Setting the dipswitches
for a particular application should be made by a competent professional, such as a Boiler/
Burner technician licensed by a state or other government agency, engineering personnel of
the burner, boiler, or furnace manufacturer (OEM) or in performance of duties based on
information from the OEM.
