The Rotate / Off DIP switch selects whether or not the control is to provide
Equal Run Time Rotation of the boiler stages. If the switch is set to Rotate,
the stages will be rotated accordingly. If the switch is set to Off, the firing
sequence is fixed starting with the module 1 to module 3.
We recommend that it be set to Rotate for most systems

The Off / Exercise DIP switch selects whether or not the control is to exer-
cise the primary pump and boiler pumps. If the DIP switch is set to Exercise,
the pumps are operated for 10 seconds after every three days of inactivity.
We recommend that it be set to Exercise for most systems.
THE CONTROL MUST BE ADJUSTED FOR YOUR APPLICATION.
IF ANY OF THE DEFAULT SETTINGS DO NOT SUIT YOUR APPLICATION, GO TO THE ADJUSTING SECTION
THAT FOLLOWS EACH FUNCTION AND WRITE IN THE DESIRED SETTING IN THE SQUARE BOX
PROVIDED FOR THAT FUNCTION. THEN PERFORM THE ADJUSTMENT AS LISTED.
THESE INSTRUCTIONS ARE WRITTEN WHERE EACH FUNCTION IS ADJUSTED IN A “ STAND ALONE ” MANNER MEANING YOU ARE PROGRAMMING
THAT ONE FUNCTION ONLY . IF YOU WANT TO PROGRESSIVELY GO THROUGH EACH STEP , JUST SKIP THE INSTRUCTIONS WRITTEN IN
ITALIC LETTERS FOR EACH STEP AND PROGRAM THE CONTROL PROGRESSIVELY THROUGH EACH FUNCTION .
IT IS BEST IF YOU TAKE A FEW MINUTES TO GO THROUGH THE ENTIRE LIST OF FUNCTIONS AND
ENTER ANY NEW SETTINGS THAT ARE APPROPRIATE FOR YOUR INSTALLATION . WHEN FINISHED ,
GO TO THE CONTROL AND ADJUST ONLY THOSE FUNCTIONS THAT HAVE A NEW SETTING LISTED .
