NOTE: If a “DIP” switch is provided on the control
PCB, verify that the switch settings are correct: 1 = OFF, 2 = ON, 3 = OFF.
OPERATION
Verify the following upon a CALL FOR HEAT signal from the heater:
1.CALL FOR HEAT LED on PCB illuminates GREEN.
2.START UP MODE LED on PCB illuminates YEL- LOW. Before 7 minutes it should go out if boiler inlet temperature is approaching the set point tem- perature.

3.The “ACTUATOR” should be in the fully open posi- tion or move to the fully open position if not already
there. (Actuator at the fully CCW position)
4.Before 7 minutes time has elapsed if the control is operating properly the “START UP MODE” LED
should go out. The inlet water temperature should be stable at a temperature between 105° F and 120° F (Normally set to 110° F) cooresponding to the Set Point Pot setting on the PCB. The actuator should have stopped moving.
