C.SAFETY INTERLOCKS

1.Low Water Pressure Limit Switch: This boiler is intended to operate at pressures exceeding 10 psig. If the water pressure drops to below 10 psig, there is a water pressure limit switch that interrupts boiler operation and displays the message "PR0" on the interface unit. The combustion air fan completes a post-purge in this event. Once the low water pressure condition is corrected the boiler will reinitiate a heating cycle if there remains a call for heat.

2.High Water Temperature Limit Switch: The boiler is equipped with a limit switch that will interrupt the heating cycle and execute a post-purge if the water temperature increases to above the limit set point of 225°F.

3.High Flue Temperature Limit Switch: The high flue temperature limit switch will interrupt the heating cycle if it senses flue gas temperatures above 210°F.

4.Blocked Vent Pressure Limit Switch: This switch prevents the boiler from operating if the vent pressure exceeds 2 inches of water column. This will prevent the boiler from operating if the vent pipe is blocked.

D.CONTROL FUNCTIONS

1.This Pinnacle boiler is equipped with a P125 Control Board. This control board with display module has the following functions:

a.Shows the boiler supply (outlet) water temperature on the LED Display as default.

b.Allows user to adjust the supply water set point, the set point differential, and change the display mode between Fahrenheit and Celsius.

c.Provides Error and Fault Codes on the LED Display.

d.Shows the actual supply and return temperatures, fan speed, flame signal (µA), boiler circulator status, boiler set point, total power on hours, boiler on hours, and the number of cycles.

e.Allows manual control of the firing rate using the Service Mode.

2.Default Display: Under normal operating conditions the default display shows the temperature of the water supply (boiler outlet) to the system. This may be displayed in Fahrenheit or Celsius according to user preferences.

3.Program Functions: By using the S3 "Program" key, the settings shown in Table 6.1 may be programmed.

a.To access the menu, press and hold the S3 "Program" key on the display module.

b.The control will enter the Supply Set Point selection.

i.The display will alternately show "C" and then the current set point temperature.

ii.The set point may be adjusted by using the S1/- (to decrease) or S2/+ (to increase) keys on the display module.

c.Pressing the S3 "Program" key again will advance to the next adjustable value, Set Point Differential, and the display will alternate between: "Ch" and the programmed value:

i.The differential adjustment is the difference between the temperature that the boiler shuts down (high) and the temperature at which it re-starts (low).

ii.The differential may be set to values between 5°F (3°C) and 30°F (17°C) in 1°F increments.

iii.The boiler will always shut down at a temperature 7°F (4°C) above the set point. The differential temperature is then applied to this value.

iv.The set point differential may be adjusted by using the S1/- (to decrease) or S2/+ (to increase) keys on the display module.

d.Pressing the S3 "Program" key again will advance to the next adjustable value. The display will read "de" and alternate with numerical value. This value is not applicable to the Pinnacle boiler.

e.Finally, by pressing the S3 "Program" key again, the display will advance to the Measurement Units selection. The display will alternate between "t" and either "F" or "C" depending on the units selected. This value may be changed by using the S1/- or S2/+ keys on the display module.

f.Pressing the S3 "Program" key once more will exit the program mode and again display the supply temperature.
