Raypak RP2100 Swimming Pool Heater User Manual


 
The RP2100 Spa/Pool Digital Control Panel features
an LCD display that provides status and service informa-
tion. During normal operation, the heater can be in the
POOL, SPA, or OFF modes.
In the OFF mode, the actual water temperature is
displayed.
NOTE: The digital temperature display may not coincide
with the temperature reading of your pool or spa thermom-
eter. The RP2100 reads the water temperature at the inlet
of the heater. Due to the circulation characteristics of any
pool or spa, the water temperature at the inlet to the
heater may differ from that observed at a given location in
the pool or spa.
In the POOL or SPA modes, the actual water
temperature is displayed along with the desired pool or
spa temperature. If the heater is firing, a flame icon will
be visible.
To adjust the desired pool or spa temperature set-
ting, make sure the control is in the appropriate mode
(POOL or SPA) and push the UP or DOWN buttons to get
the desired set point temperature.
If there is a safety fault, a fault code will be displayed
along with a service indication. If the PRS fault code is
displayed, it indicates that there is insufficient flow
through the heater. Make sure the pool filter and pump
strainer are clean before calling a service representative.
Remote control operation is possible by connection
to the remote terminals on the control board. (P7) When
the remote control is operating the heater, the display will
alternatively indicate REM and the actual water tempera-
ture.

Notice to owner- Thermostat operation
Your heater is equipped with a microprocessor-
controlled thermostat that controls the pool or spa
temperature by measuring the etmperature of water
coming back through the heater. It will then monitor the
temperature and turn the heater back on when it senses
that the temperature is falling below set point. Small
fluctuations in the return temperature are experienced
during the operation of the heater. The thermostat is
calibrated with a very close tolerance to insure accuracy
of the set temperature. Thus, slight fluctuations may
cause your heater to cycle on and off frequently.
This phenomenon is not a problem. It will not harm the
heater nor interfere with its function to precisely control
the temperature of the pool or spa.
The pool heater thermostat on the upper front panel
of the heater controls the pool/spa water temperature.
This control center contains a mode button, up and down
temperature adjustment buttons, and a LCD display. The
MODE button functions as a means to turn the heater off
or on in either the pool or spa temperature setting. The
LCD display indicates the mode the heater is in and the
actual water temperature. If the mode is in POOL or SPA,
the desired pool or spa temperature will also be displayed
and may be changed using the UP or DOWN buttons. A
manual switch is also provided on the right side heater
cabinet to allow the heater to be turned off. If there is a
problem in operating the heater, the fault will be displayed
and a service indicator will flash.
The electronic thermostat cannot be set above
selected maximum set points. The maximum set point
are factory selected at 104°F for spa and pool. These can
be changed to a higher or lower value to suit your needs,
but can never be set above 107°F. In order to change the
maximum set point, push the MODE button to the OFF
mode. Open the front panel as shown in the previous
section. Find the SETMAX button on the back of the
circuit board. Push the SETMAX button until the display
indicates SET. Either POOL or SPA will be displayed
with the upper temperature limit. If the desired mode is
not being displayed, press the MODE button to switch to
the desired mode. Using the UP or DOWN arrow
buttons, adjust the upper temperature to the desired
maximum setting. If a button is not pushed for 5 seconds,
the control will return to the OFF mode.
