•  The  up  and  down  buttons  are  used  to  navigate  menus  and 

adjust user settings.

 

•  The  operational  buttons  are  used  to  enter/exit  menus,  select 

menu items, activate adjustment modes and confirm or cancel 

new user settings. The operational buttons are multifunctional, 

their current function is defined by the text that appears directly 

above each button on the LCD screen. 

the desKtop screen

During  normal  operation  the  control  system  will  display  the 

"Desktop"  screen  on  the  LCD  which  is  the  default  screen.  The 

control  system  will  return  to  the  Desktop  screen  when  there  are 

no active Fault or Alert conditions or when there has been no user 

input for several minutes.

•  Manufacturer and water heater model information is displayed 

in Title Bar at the top of the Desktop screen. Menu titles are 

displayed in the Title Bar when navigating the control system 

menus.

•  The  first  temperature  shown  on  the  Desktop  screen,  Tank 

Temperature, is the temperature of the water inside the water 

heater's storage tank - commercial models only.

•  The Operating Set Point is also shown on the Desktop screen. 

The Operating Set Point is the temperature at which the control 

system will maintain the water inside the storage tank.

•  Beneath the Operating Set Point is the "Status" line. The Status 

line shows the current operational state of the control system in 

real time. See Table 10 for a description of the various operating 

states.

•  The Desktop screen also displays animated "Status Icons" to 

convey operational information, see Table 9 for a complete list 

and description of the Status Icons.

overvIew

The  water  heaters  covered  in  this  manual  are  equipped  with  an 

electronic control system that regulates water temperature inside 

the storage tank. Heating cycles and ignition are managed by the 

control system. The ECO (energy cut out), Flame Sensor, pressure 

switches  and  Temperature  Probe  is  monitored  by  the  control 

system. The Combustion Blower, Igniter and the 24 Volt Gas Valve 

are all energized by the control system.

The  main  components  of  the  control  system  are  a  UIM  (user 

interface  module)  and  a  CCB  (central  control  board).  The  UIM 

is  located  on  the  top  front  side  of  the  water  heater. The  CCB  is 

mounted on top of the water heater inside a protective enclosure.

coMMercIal and resIdentIal Models

The  water  heaters  covered  by  this  manual  are  produced  for 

commercial and residential use. The control system is programmed 

differently  for  commercial  and  residential  models. There  are  two 

differences in control system operation between the residential and 

commercial products:

•  Commercial  models  will  display  Tank  Temperature  on  the 

Desktop screen, residential models will not.

•  Commercial  models  can  regulate  tank  temperature  up  to  a 

maximum  of  180°F  (82°C),  residential  maximum  is  160°F 

(71°C).

control sYsteM navIGatIon

All  operational  information  and  user  settings  are  displayed  and 

accessed from the UIM. The UIM houses the control system's LCD 

(liquid crystal display) and five snap acting (momentary) user input 

buttons; an up, down and three multifunction operational buttons 

below the LCD, see Figure 36.
