The PCB control board (Printed Circuit Board) is a thermostatically controlled circuit board that allows the electric tankless water heater, model AE115 & AE125 to be manually controlled by a temperature dial that would range in temperature from 86-131 degrees. The PCB in conjunction with a flow transducer enables the PCB to turn on additional elements in the heater as necessary depending on the amount of gallons per minute (gpm) flowing through the heater.
The PCB would recognize many factors in the function of the heater to maintain a steady temperature and all of this is determined on where the temperature knob is set too, the gpm flowing through the heater and the temperature of the incoming ground water.
To obtain the maximum heating potential of the Powerstar electric tankless water heater, it must be wired correctly and have the full required voltage to the unit. The Powerstar AE115 would require 2 independent double pole 40 amp breakers wired with 8 gauge wire and could draw a maximum of 80 amps at full flow through the heater. The Powerstar AE115 would require the home to be supplied with a minimum of a 150 amp service. The Powerstar AE125 would require 3 independent double pole 40 amp breakers wired with 8 gauge wire and could draw a maximum of 120 amps at full flow through the heater. The Powerstar AE125 would require the home to be supplied with a minimum of a 200 amp service.
The maximum inlet water temperature allowed into the heater is 86 degrees Fahrenheit.
The Powerstar AE-115 & AE-125 have had many upgrades and engineering improvements over the years. In January 2007 the AE-115 & AE-125 went from having copper canisters that contain the heating elements to an upgraded Polymer module. The PCB control board was also upgraded to maintain a more steady temperature that works with the heating elements in the polymer modules.
Below are the designated PCB control board part numbers for the units before and after 2007.
Before 2007 with serial #60A 00000 or lower:
Powerstar AE-115 PCB with copper can units, part #93-793777
Powerstar AE-125 PCB with copper can units, part #93-793778
After 2007 with serial #60A 80000 or higher:
Powerstar AE-115 PCB with polymer units, part #93-793843
Powerstar AE-125 PCB with polymer units, part #93-793844

POWERSTAR AE-115 AND AE-125
The Powerstar Electric Tankless Water heaters model Powerstar AE-115 and Powerstar AE-125 are designed for whole house use and would replace a traditional 40 gallon electric tank heater that will provide endless hot water throughout the home. With two powerful and compact models to choose from, AE-115 or AE-125 it will fit just about anywhere and is built to last.
These 2 Powerstar units have specific power requirements as the AE-115 would require the home to have a minimum of a 150 amp service to the home and would require 2 double pole 40 amp breakers wired with #8 gauge wire as the unit can draw up to 80 amps when at full usage. The AE-125 would require the home to have a minimum of a 200 amp service to the home and would require 3 double pole 40 amp breakers wired with #8 gauge wire as the unit can draw up to 120 amps when at full usage. Please view this link for the AE115 and AE125 power requirements:
The Powerstar AE-115 & AE-125 models have had many new upgrades over the years. The biggest upgrade was that the canisters inside the tankless heater used to have copper canisters and then in 2007 they were upgraded to poly tanks that are more durable and would handle expansion and contraction of the heat better and would be less susceptible to mineral buildup.
The Powerstar AE-115 is designed for 1 major application at a time and is recommended for installation in homes that are in the southern regions of the United States as the incoming ground water is warmer giving the heater a higher temperature degree rise.
The Powerstar AE-125 is designed for 1 major application and 1 sink at a time and is recommended for installation in homes that are in the northern region of the United States where the incoming ground water is cooler and this heater will be able to give a higher degree temperature rise.
The Manufacturer of the Powerstar AE-115 & AE-125 require that there must be at least 3-4 feet of copper water piping coming from the units on the hot and cold water side before attaching to any pex piping as this is due to thermal expansion.
The Powerstar AE-115 & AE-125 are both UL & CSA approved.
