CONTROL OVERVIEW
PART 9: CONTROL OVERVIEW
The control is one of the primary safety devices of the heater. The control monitors the safety sen-
sors of the heater to assure safe and efficient operation. The control has many features to address
configurations associated with hydronic design. This section addresses the programming features
of the control. It is important to fully understand the capability of the control. This section address-
es Phoenix Evolution Settings / System Settings / Maintenance Settings and System Diagnostics to
help customize your control. This control is programmed to run with factory defaults that may
already fit your hydronic design and may not require any adjustment at all.
A. NAVIGATION OF THE DISPLAY
The display includes a two line backlit LCD readouts to provide informative messages about the
operation of the Phoenix Evolution. Many operating parameters can be viewed and adjusted by

to change the value. Repeat until the correct code is entered. Press the ENTER key to accept the code
entered. If the code is correct, the readout will change to the appropriate screen. If the programming
code is not accepted the readout will continue to display as shown above.
The ENTER key is also used to enable a parameter for editing. After the user navigates to the desired
parameter, the user would hold down the ENTER key for one second. When the ENTER key is
released, the parameter value will begin to blink. The parameter can now be changed using the
ARROW keys. After the new value is displayed, the user then presses the ENTER key for 1 second
to lock the new value of the parameter in. The value will then stop blinking.
ARROW Keys – The arrow keys (right and left) are used to navigate between the default Display
and Status Display. The keys are also used in programming modes to change between the pro-
grammable parameters. It is recommended you use the Menu Maps in the back of this manual and
the detailed menu instructions printed in this section to help in menu navigation.
ARROW Keys – The (up and down) arrow keys are used to navigate between the various param-
eters displayed in the menu. After the parameter is enabled for editing by pushing the ENTER key,
the keys are used to adjust the parameter upward or downward to the desired value.
