Set Point Lockout

Make sure the control is in the ON mode (POOL
or SPA), press and hold the Up and Down buttons for
5 seconds. The set point will be locked and the control
will operate in the mode it was in when the Set Point
Lockout occurred. If an attempt to change the set point
is made while the control is in Set Point Lockout, the
control will display SET POINT LOCKED . To unlock
the Set Point Lockout, press and hold the Up and Down
buttons for 5 seconds. The unit will display SET POINT
UNLOCKED .

Water Pressure Switch Adjustment

CAUTION
The water pressure switch should be adjusted
to turn the heater off when the pump is off.
Setting the switch to close at too low of a fl ow
can damage the appliance. Adjust the switch
to turn the heater off, not on.
ATTENTION
Le manocontact de pression d'eau doit être
réglé de façon à ce que l'appareil cesse
de fonctionner si la pompe s'arrête. Si le
manocontact est réglé pour se fermer lorsque
le débit d'eau est trop faible, l'appareil risque
de s'endommager. Réglez le manocontact
pour qu'il arrête l'appareil, et non pour qu'il le
mette en marche.
PRECAUCIÓN
El interruptor de la presión del agua, deberá
ajustarse de forma que el calentador se apague
cuando se apague la bomba. La calibración del
interruptor para que pueda apagarse con fl ujos
demasiado bajos podría estropear el equipo.
Ajuste el interruptor para apagar el calentador,
no para encenderlo.
The pressure switch is preset at the factory for
activation at 2 psi (14 kPa). This is the minimum
setting for the water pressure switch and works for
all basic installations as shown previously in Section
3.1 and Section 3.5 in this manual. Only adjust the
water pressure switch if the heat pump does not
operate when the proper flow is applied to unit or if
the heat pump does not shut off when the filter pump
is off. Occasionally, unusual plumbing configurations
or necessary restrictions in the plumbing may cause
pressure sensing problems. In these rare situations, the
plumbing system configuration may require adjustment
of the water pressure switch.
Adjustment of the pressure switch may be
necessary if any part of the filter system piping is 3 feet
(1 m) or more above the top of the heat pump jacket.
Do not adjust the pressure switch if the heat pump
is installed more than 11 feet (3.5 m) above or 5 feet
(1.5 m) below the pool surface. Consult your local
Jandy dealer for recommendations.
On some installations, the piping from the heat
pump to the pool is very short. The back pressure
could be too low to trigger the pressure switch. If this
happens, it may be necessary to install a directional
fitting or elbows where the return line enters the
pool. This will increase back pressure enough for the
heat pump to operate properly. If this configuration
is necessary, be sure to check that the system flow is
above the minimum requirement of 30 gpm (114 lpm)
after the direction fitting or elbow has been installed.
Make sure the pool filter is clean before making
any pressure switch adjustment: A dirty filter will
restrict the water flow and the pressure switch cannot be
adjusted properly.
To adjust the pressure switch:
1. Be sure that all valves in the system are set to
allow water fl ow through the heat pump. Start the
fi lter pump.
2. Set the heat pump control to call for heat. Set the
heat pump control to the POOL HEAT mode.
3. If the heat pump control displays "NO FLOW",
then the fl ow in the system may be below the
minimum fl ow of 30 gpm (114 lpm) needed for
the safe operation of the heat pump. Investigate
and correct any fl ow problems before adjusting the
water pressure switch.
4. Remove the heat pump's control access panel. The
water pressure switch is located in the lower left
corner of the control compartment.
5. After confi rming the fl ow rate is at a minimum
of 30 gpm (114 lpm), slowly rotate the thumb
wheel on the water pressure switch in a
counterclockwise direction until the "NO FLOW"
indicator disappears from the control display.
Remember that there is a time delay before the
heat pump compressor will start.
6. Once the heat pump is running, turn off the fi lter
pump. The heat pump should turn off immediately.
7. If the heat pump continues to operate when the
