Problem Solving a Solar System<br />
SunTouch solar is not operating<br />
Verify the circuit breaker at sub-panel is not tripped. If the 3 AMP Circuit Breaker on the on SunTouch is<br />
tripped, it is most often due to a defective Circuit Board or Valve Actuator. Try disconnecting each one<br />
separately to determine which one is at fault.<br />
Solar will only operate when the solar temperature is 6° warmer than the water temperature.<br />
Inspect the appropriate sensor cable and wire connections and replace the appropriate temperature sensor if<br />
necessary. An ohm meter can be used to take a reading of the sensors. See table on page 68.<br />
If the temperature sensors are not at fault, replace the SunTouch circuit board.<br />
Water flow to panels switch does not operate the valve actuator<br />
If the valve actuator does not operate when using the WATER FLOW TO PANELS Switch (sliding switch<br />
between ON and OFF), either the valve actuator or the SunTouch circuit board is at fault.<br />
First verify that the toggle switch located on the valve actuator is either in the ON1 or ON2 position.<br />
With a voltmeter, check the output voltage of the VLV1 socket located on the SunTouch circuit board. When<br />
the WATER FLOW TO PANELS Switch is in the OFF position, the top and middle pins should read 24 VAC.<br />
When the WATER FLOW TO PANELS switch is in the ON position, the top and bottom pins should read<br />
24 VAC.<br />
If voltage readings are correct, replace the valve actuator. If voltage readings are incorrect, replace the<br />
SunTouch circuit board.<br />
Checking The Temperature Sensors<br />
Disconnect temperature Sensor wires from the SunTouch circuit board, and test sensor using an ohm meter.<br />
See table on page 66.<br />
Testing the Solar System<br />
To test the SunTouch in “SOLAR ONLY” mode: Set the “System Control” menu setting to “SOLAR ON”<br />
verify the valve(s) are in the solar position. Then set the menu setting to “SOLAR OFF” and verify the valve is<br />
in the normal recirculating pool position. If the valve(s) positions are working in reverse, toggle the valve<br />
switches and test again.<br />
Air Sensor ERROR<br />
If after enabling the optional air sensor (see page 24) the main screen displays AIR Error or Solar Sensor<br />
ERR, this indicates the solar sensor is not connected or it is out of range. Check that the sensor is connected<br />
correctly to connector J9 on the SunTouch motherboard (see page 53).<br />
