General Operation

How the water heater operates

Access modes

The Armor X2 uses two (2) advanced stainless steel heat exchangers and two (2) electronic control modules that allow fully condensing operation. The blowers pull in gas and air and push flue products out of the water heater through the heat exchangers and flue piping. The control modules regulate blower speeds to control total water heater firing rate. The gas valves sense the amount of air flowing into the water heater and allow only the right amount of gas to flow.

Sequence of operation

Table 1A shows control module normal sequences of operation for each individual control module. Additionally, the control modules are programmed to synchronize their combined modulation rates in order to maximize total water heater efficiency.

User

The user can view all of the settings on the LCD screen. By entering the user password (0704), the user can adjust the User Set Point, Outdoor Shutdown, Night Setback, Boost, HW Water Heater Output Set Point, Backlight Time, and Backlight Brightness settings.

Installer

Most parameters are available only to the installer, accessible only by entering the installer access code (5309).
