Turbotemp 125 Pool and Spa Heater Installation and User’s Guide
If the pressure switch is 0.3M (1 ft.) below or above the pool water level, reset the switch
so that it is open when the pump is off and closed when the pump is running. Turn the star-
wheel on the switch clockwise (
) to
raise setting (heater below the pool) and
counterclockwise (
) to lower the
setting (heater above the pool - see Figure
6). Test the
switch after resetting.
NOTICE:
When the heater is mounted more
than 1.5M (5 ft.) above or 1.2M (4 ft.) below
the deck level, a Pressure Switch is no
longer adequate. A Flow Switch must be
installed instead.
NOTICE:
Heater operation with incorrect
Pressure Switch setting may cause
operation with no water flow. Operation
of the heater without sufficient water flow
may cause severe damage and will void the
warranty.
HIGH LIMITS
A “High Limit”, is a safety device that opens the electrical circuit and shuts off the heater based
on a water temperature set point within the “High Limit Device”. The Turbotemp 125 heater has
two (2) high limit devices which are located on the main inlet / outlet header (see page 43 item
6).
OPERATION OF IGNITION MODULE
The Ignition Module (see Figure 7), is
microprocessor based and operates
on 24VAC supplied by the transformer.
The control utilizes a microprocessor to
continually and safely monitor, analyze, and
control the proper operation of the gas flame
holder. The module with the presence of the
flame sensor, using flame rectification.
TEMPERATURE SETTING
The heater temperature setting is factory set at 25.6° C (78° F). for pool mode and 37.8° C (100°
F). for the spa mode. To adjust the set temperature, use the up and down arrows to set the pool/
spa thermostats to a minimum temperature of 18.3° C (65° F.), or a maximum of 40° C (104° F).
If you desire to heat only one body of water, the thermostat is capable of an off mode. As an
example, if you only wish to heat the spa and not the pool, simply depress and hold the pool
down arrow, and the thermostat will lower its setting to 18.3° C (65° F.) then go to an off mode.
Note: See below to change the heater’s factory set temperature settings.
ADJUST THE MAXIMUM TEMPERATURE SET POINT
1. Unbolt and remove the door panels (see Figure 8).
2. Access the control panel board on the underside of the top cover. Locate the yellow button
on the corner of the control board.
3. Push the
Max. Temp. Set Point
button on the back of the control board (see Figure 9).
The following sequence should happen:
1. The unit will come on and the
POOL ON
light will come on.
2. Press the
TEMP
or
TEMP
pad (on TOP of the panel) to set maximum pool temperature.
3. Wait up to 30 seconds; the
POOL ON
light will go off and the
SPA ON
light will come on. To
override the time delay, push the
Max. Temp. Set Point
button again.
4. Press the
TEMP
or
TEMP
button on the control panel and set maximum spa temperature
to 40°C (104°F) or less.
5. Wait up to 30 seconds; the
SPA ON
light will go off and the unit will shut down. To override
the time delay, press the
Max. Temp. Set Point
button again.
Star Wheel
A reference scale is on
the back of pressure switch
Turn star wheel
clockwise
to raise
pressure set point if pressure switch is
more than 4 feet (1.2M) below water level
Turn star wheel
counterclockwise
to lower
pressure set point if pressure switch is more
than 5 feet (1.5M) above water level
