PVI Water Heater How-To

View Menu (Home Screen – Default Display)

The View Menu is the default display (home screen) of the EOS control system. The View Menu displays general information about the water heater’s operation and status. The default display includes a Burner Firing Rate % Icon for modulating units, a Pump Icon that is visible whenever the integral tank circulator is energized, and Failure Messages if the unit is in an alarm or error condition.

Changing the Operating Set Point (USER Level Access)

The water Conquest water heater operates to satisfy the stored water temperature set point of the EOS control. The value of the controls’ set point is the desired stored tank water temperature. The unit ships with a factory set point of 120⁰F.

Although the setpoint can be displayed in the VIEW menu, it is necessary to enter the Control System Menu in order to make adjustments to the water heater setpoint and other operational parameters.

To Change The Water Heater SetPoint

1. From the VIEW Menu, press and hold the HOME button for 3 seconds.
2. Touch NEXT ITEM or ITEM BACK buttons to navigate to the SETUP
3. Touch the ENTER button then navigate to the SETPOINT using the NEXT ITEM
4. The new value will be saved when you navigate away using NEXT ITEM, ITEM BACK, or HOME button.

Potentiometer (Operating SetPoint for Standalone Operation)

The PIM Ignition Control will continue to operate the Conquest water heater at a 120 degree internal setpoint should the touch screen control fail, or communication between the two devices is interrupted. This internal setpoint can be adjusted using the potentiometer to maintain a different operating temperature under these circumstances if desired. This feature is intended to be used on a temporary basis, since accuracy of temperature control is dependent upon the touch screen control.

IMPORTANT: It is recommended that at the time of commissioning, the startup technician adjusts the potentiometer to the desired set point displayed in the OPERATOR screen located in the SOURCE control system menu. The standalone set point can be adjusted independently of the touchscreen but a specific setting may be difficult to achieve using the temperature index on the PIM. (See POTENTIOMETER Adjusting the Setpoint.) NOTE: If the operating setpoint is ever changed after initial commissioning, the potentiometer should be readjusted as well.

Setting The Real Time Clock (User & Installer Level Access)
