About this product
Description
The control board supplies power to the combustion air blowers through a series of safety interlocks. The heater interlocks consist of:
• the two water pressure switches (PS), which senses that the pump is running,
• the tridicator gauges (2) which monitors the water temperature in degree Fahrenheit and pressure in psi.
• the high limit switch (HLS), which opens if the heat exchanger outlet temperature goes above 135° F (57° C), and
• the two air flow switches (AFS), sense the pressure drop across the air metering orifices.
• the two thermal fuses (TF) open if the flue gas temperature reaches 187° F (86° C).
• the automatic gas shut-off (AG1, AG2) switches, which open if the heat exchanger outlet temperature goes above
150° F (66° C).
• the float switch (FS) which opens if the condensate overflows at the float switch due to blockage in the condensate
drain hose or neutralizer cartridge.
• the stack flue sensors (SF1, SF1), which shut down the heater if the flue gas temperature reaches 170° F (77° C).Highlights
