Settings Menu: Man Heat (Off/On)

By default manual heat (Man Heat) is set to “On,” which allows your spa to begin to heat whenever it is
manually switched on, (by pressing the

Valves (V)

button and

Filter Pump (F)

button on the outdoor control

panel or the

Spa

button on the Indoor Control Panel), even if the Heat menu setting is set to “OFF” (see page

30). Your spa will also begin to heat when switched on by the iS4 Spa-Side remote. This feature allows you to
program your spa to filter daily with the heater set to off, and then be ready to heat whenever the Spa button is
pressed manually.

Settings Menu: Calibration

The EasyTouch PL4/PSL4 Control System includes two temperature sensors (10 k

Ω

) for water and ambient

air temperature. You can also add an additional sensor for controlling solar heating systems. Generally, these
sensors are accurate and you do not have to calibrate them. However, long plumbing runs and water features
can cause temperatures at a body of water to be different from the temperature sensor reading. You can
manually recalibrate the sensors to adjust for this. You only need to calibrate one body of water, since the
temperature sensor is common to both the pool and spa. The system must be in “Service” mode to calibrate
sensors.

Calibration

Before you start, you need an accurate all weather thermometer. If you are calibrating the air sensor, wait until
the sensor is not in direct sunlight. For the air temperature sensor, make sure that the sensor is located in the
shade for accurate readings.
To calibrate the water, air and solar temperature sensors:

MENU

SETTING

CALIBRATION

1. Press the

Mode

button on the control panel to place the system in “Service” manual mode.

2. Press the

Filter Pump (F)

button to switch on the pool/spa filter pump.

3. Place the thermometer in the spa or pool water. Take an accurate temperature reading. When

calibrating the air sensor, place the thermometer next to the air sensor. The air sensor is normally
located near or under the EasyTouch PL4/PSL4 Control System Power Center enclosure, not inside
the enclosure. Take an accurate temperature reading in the shade.

4. Use the

Down

buttons to raise or lower the water temperature to match the corresponding

thermometer temperature reading.

5. After calibrating the water sensor, use the

Right

button to move to the “AIR” setting and repeat

step 4 and repeat the procedure for the solar sensor. Ensure that the solar sensor is in the sun for
accurate readings.

6. After calibrating all the sensors, press the

Menu

button to save the settings and to return to the

Settings menu options. Press the button again to return to the main menu options or press again to
return to the main screen.
