Control Settings - Raypak 3450 Installation And Operation Manual

The user can access these control settings by pressing
and holding the MENU button for 5+ seconds. Any
changes to values are stored into the non-volatile
memory when the MENU button is pressed – which
also toggles to the next setting. Failure to press any
buttons for 60 seconds will cause the screen to revert
back to its previous operating mode screen. However,
the user mode can also be exited by pressing and
holding the MENU button for 5+ seconds.
NOTE: See Table G on page 38 for Operational
Status Messages that you may see during normal
operation.
Set Current Time
This allows setting of the current time. The time is
followed by an "A" or "P" for AM and PM respectfully.
The control has a 24-hour time clock – although it is
NOT a 7-day time clock. The time clock is used for
control of the pump periods and AUX1 & AUX2 times.
C/F Display
This setting is used to define the units of measure
for all temperature readings. Fahrenheit is the default
value. You can change the setting to Celsius by
toggling the UP or DOWN button and then pressing
the MENU button to lock in the change.
Spa Max Temp
This setting is used to define the maximum temperature
that the control can be set at for the Spa operation.
The range is 65°F – 104°F (18°C – 40°C). The default
value is 104°F (40°C).
Pool Max Temp
This setting is used to define the maximum temperature
that the control can be set at for the Pool operation.
The range is 65°F – 95°F (18°C – 35°C). The default
value is 95°F (35°C).
Pump Periods
When the Pump Operation in the Installer's Menu is
set to "4-Speed Enabled" or "Variable Enabled", this
allows the setting of Pump Periods from this menu.
When setting this parameter, the control displays
"Pump Periods" on the first line of the display. The
number of pump periods (0 – 4) is displayed on the
center of the 2 line. Pressing the UP or DOWN
nd
buttons increments/decrements the number of pump
periods – factory default is 1. If a non-zero number of
pump periods is selected when the MENU button is
pressed, the control will prompt for On/Off times for
each of the selected number of pump periods.
Temperature Control
The control uses the appropriate Pool or Spa setpoint
as selected in the Operating mode. The heat demand
begins when the water temperature is 0.5°F (0.3°C) or
more colder (or 0.5°F (0.3°C) or more hotter in cooling
mode) than the setpoint.
Additional Features
Pump Control
The control is equipped to operate the system pump.
The control provides for an output for a single speed
pump (0.75A @ 24VAC maximum) as well as an
output for a variable speed pump (10mA @12 VDC).
Four signals are provided for selection of 4 discrete
speeds for a variable speed pump. The control can
be configured to provide a PWM signal on the speed1
output. The control will energize the pump at the
requested speed for each of the pump periods set in
the program mode. If a heat pump demand is present
during a scheduled pump operation, the pump runs
at the override speed (Speed 1) regardless of the
scheduled speed. When the pump is active because
of scheduled operation and there is no active heat
demand, the control sets the 3-ways valve outputs to
the states set in the program mode schedule.
Low Ambient (Outside) Lockout
The control is equipped with a Low Ambient Lockout
feature which will prevent the start of a new cycle if the
ambient temperature is lower than the programmed
value. This feature is accessed through the Installer/
Service Sub-menu as noted in INSTALLER/SERVICE
menus on pages 17 - 28. The default value is "OFF",
but the temperature can be adjusted between 30°F
and 50°F (-1°C and 10°C). This feature can be enabled
if it is desired to not operate the unit if the temperature
falls below this value. NOTE: This feature will NOT
stop the operation of an existing cycle, it will only pre-
vent operation of a new cycle.
An open ambient temperature sensor – display will
read "Air Temp -46°F" (-43°C) – will trigger an "Outside
Lockout" error if the Low Ambient lockout is enabled.
A shorted – display will read "Air Temp 282°F" (139°C)
– ambient temperature sensor will also cause the
control to shut off the compressor regardless of if the
Low Ambient lockout is enabled.
Control Lock Box Mode
The control is equipped with a Control Lockout feature
which is accessed by pressing and holding the MENU
and DOWN buttons for 5 seconds. The user will be
prompted to enter a 3-digit code. A cursor flashes
under each digit in the 3 digit code when that digit is
being set. Pressing the UP or DOWN buttons increas-
