User Modes - Rheem Raypak 2450 Installation And Operation Manual

If the membrane switch remains inactive for 180 seconds
(3 minutes), the screen will revert to the current view.
On HEAT ONLY and POWER DEFROST models, the
options available by pressing the MENU/SET (MENU)
button are POOL HEAT, SPA, TIMED SPA and OFF.
On HEAT/COOL models, the options available by pressing
the MENU/SET (MENU) button are POOL HEAT, POOL
COOL, POOL AUTO, SPA, TIMED SPA and OFF. The
cooling setpoint can be adjusted in the range of 50°F
(10°C) to the Cooling Deadband value below the heating
setpoint. This allows use in Plunge Pools. Adjust the
cooling setpoint accordingly.
Upon initial application of power, the heater control briefly
sets all segments on the LCD at power-up. On a normal
power-up, the control displays the current software revision
and the model type configuration (HEAT ONLY, POWER
DEFROST or HEAT/COOL) on the LCD for 2 seconds
and then resumes the user-selected mode it was in before
power was interrupted.
Setpoints are read from non-volatile memory. If the self-
diagnostic check indicates corrupted values, "EEPROM
Fault" is displayed on the LCD and operation is prohibited
until setpoints are manually set.
If unit type has not been set (like during the replacement of
the control), the control prompts the user to set the model
type (HEAT ONLY, POWER DEFROST, or HEAT/COOL)
before any device operation is enabled.
Upon initial installation, there are several items that
must be defined and programmed depending on the
configuration and accessories intended to be controlled by
the control. These include: (1) Pump control (Yes or No
and then what type of control – 4-speed control or variable-
speed control), (2) 3-way valve control (Yes or No), and (3)
Auxiliary control (Yes or No and then what type – External
Heat, Auxiliary Output or Remote Output).
Once these choices are made, then additional information
relating to the establishing of pump periods, pump speeds
during each period and Return/Suction Valve positions
during each period must be determined and set in the
control.
The options for the control can be very simple or very
detailed, depending upon the needs of the installation.
Once programming is completed, the control is ready for
operation.
The user may select one of several operating modes. Each
mode is selected by pressing the MENU (button is labeled
MENU/SET, but MENU is used in these instructions for
simplicity) button to cycle between the modes. Each press
of the MENU button selects the next mode. There is no
automatic increment from continually pressing the MENU
button. In fact, continually pressing the MENU button (for
3+ seconds) will move the user into the USER Menu.
