GUIDE
danger of a fatal or serious shock hazard may be present. These tests are
indicated by boldface times italic font [characters like these].If you do not possess
the electrical skills required to perform these tests, obtain the services of a qualified electrician.
LIGHT DOES NOT LIGHT.
(The SOLAR ON light is not ON
when the LX220 is in the
“Manual On” position.)
2. Check for tripped breaker at the main power panel.
3. Ensure that timers are turned on.
4. Check for loose power wire nut inside LX220.
5. Check for 220-vac power inside the LX220 with voltmeter.
ON.(Solar On light is On.
Sensor Service Required lights are
Off.)
2. PCS1 is unplugged at attic outlet or power is mising.
3. Power is incorrectly wired at LX220.
4. LX220 relay is not activating; unplugged; or defective.
5. Internal motor thermal cutoff. Wait 15 minutes & retry.
6. Defective PCS1 power cord or plug.
7. Defective 5µf starting capacitor.
8. Defective Motor.
9. Defective Solar controller.
10. Check for 220 vac at attic outlet with voltmeter.
DOESN’T ROTATE FAN
BLADE.
If motor is okay, it will restart after it has cooled down.
2. Disconnect power to check motor starting capacitor: Remove
the two brown wires on the starting capacitor, which is located
inside the venturi assembly. Connect the two wires together &
insulate with electrical tape. Turn the power on and see if the
motor now turns. Result A: Motor turns. This indicates that
the starting capacitor is defective. Result B: Motor still
hums. This indicates a defective motor. Test assumes that the
motor is cool to touch and has not been thermally overloaded.
Do not run motor with starting capacitor wires shorted for
longer than 5 minutes. Replace defective part.
DOES NOT TURN OFF
(Tapping the internal LX220
relay turns the system off.)
Loosen the relay’s mounting wing nut so
that the wing nut is just holding relay in place. Overtightening of the wing
nut can close the gap between the relay’s contacts. This can cause the relay to
operate and appear like the system is turned on.
Caution: Dangerous power may be exposed near this relay.
ROTATES IN WRONG
DIRECTION.(“Solar On” turns
water off to PCS1.)
2. Valve was mis-staged as it was assembled. Reverse plug to “Spa” UP for
correct operation or turn valve operator switch to other “ON”.
3. Place switch on valve operator to its second “ON” position.
NOT ROTATE TO PROPER
STOP POSITION.(Valve
stops before it should.)
2. Internal cam needs adjusting.
3. Internal mechanical stop needs adjusting.
4. Defective valve operator. Replace.
ROTATES IN ONE
DIRECTION. (Valve rotates to
ON position but will not rotate
to OFF. POWER ON and
SOLAR ON lights are both on.
Sensor Service Required lights are
both off.)
1. Defective limit switch mechanical stop inside of valve operator.
2. Defective internal limit switch inside of valve operator.
3. Defective limit switch circuit inside of valve operator.
4. Defective valve operator.
This indicates that the valve operator is okay.
ROTATES SLOWLY

reach its end stops.)

operator switch itself. Turning the LX220 switch to manual ON or Automatic
does not operate the valve. Sensor service lights are OFF. Power ON light is
lit.
1. The LX220 is wired for 220 VAC operation but is supplied with 120 VAC.
1. Shorted pool water temperature sensor.
2. Open water sensor.
3. Cable problem from LX220 to water sensor.
4. Loose screw at LX220 WTR terminals.

wires. Connect temp sensor in series with white wires.
2. Loose screw at LX220 SOL terminals.
3. Cable problem from LX220 to attic temperature sensor.
4. PCS1 is mounted upside down causing open float condition.
5. Leak detection float inside PCS1 is detecting excess water.
6. Leak detection float inside PCS1 is defective.
7. Shorted attic temperature sensor.
8. Open attic sensor.
(PCS1 does not appear to be
heating the pool.)
2. Pump Timer(s) out of sync with solar energy collection time.
3. Water flow valves to PCS1 are shut off.
4. Bypass valve operator does not route water to PCS1. VOR switch is
in the wrong “ON” position or plug is upside down (older vor’s).
5. Pool Cleaner water flow interfering with PCS1 water flow.
6. LX220 is not in “Automatic” mode.
7. LX220 Solar Controller does not supply power to PCS1.
8. PCS1 water flow and fan power are out of sync with each other.
9. Defective temperature sensor(s) or Open leak detection float.
10. Attic sensor located in the discharge air of the PCS1.
11. Attic sensor not located at the peak of the attic.
12. Defective fan motor on PCS1.
13. No airflow through unit’s water coil. Coil facing the wrong direction.
14. Insufficient airflow caused by obstacles, coil too close to wall, etc.
15. PCS1 is located on the floor of a large standup attic. The PCS1 should be
located as close to the peak of the attic as is possible. Heat rises in attics.
16. Short circuiting of the PCS1 airflow. Unit is mounted in such a way that
air discharged from the face recirculates back to the intake of the coil. Thus
the coil does not take in heated air on a regular basis.
17. Poor location for the PCS1 inside of the attic.
18. Excessive pool water cooling caused by attached waterfalls.
NIGHT OR TOO EARLY
(No attic heat is available for the
pool. The attic is cooler than the
pool or the same temperature.)
the LX220 a false indication of cold water temperatures [the attic falsely
appears much warmer than the pool causing the PCS1 to cycle on]. Solution:
Insulate the pipe around the water temperature sensor and cover with plastic to
waterproof. 2. Sun heating causing water sensor to give false reading.
(The swimming season is not as
long as you would like but the
PCS1 is heating the pool.)
2. Heat loss opportunity exceeds heat gain opportunity. I.E. The pool is
uncovered and the nights are cold causing excessive heat loss, which is not
recovered during the solar day. Solution: Use a pool blanket or cover to
eliminate the excessive heat convection losses, which occur directly from the
surface of the pool. This will allow the pool to retain the free solar heat and
extend the swimming season.
3. Solar heating capacity and pool heat retaining capacity are no longer
adequate for the current season’s weather. Solution: Use a backup heater to
further extend the swimming season until the pool has to be winterized [if
required].
2. Loose fan blade.
3. Loose motor mounting or cabinet hardware.
4. Lack of foam base for PCS1 to rest on.
5. Rigid mounting of PCS1 to building structure. Mount PCS1 support
platform to roof using chains. This eliminates amplification of vibration by
the wood structure, which occurs when rigidly mounting platform.
6. Contamination on fan blade causing imbalance.
7. Motor bearings defective.
8. Mounting may require rubber isolation dampening devices.
9. PCS1 mounted using rigid pipes that are not supported properly.
FILTER
(Total pressure should be less
than 22-27 lbs. in the typical
installation with a clean filter.)
2. Check position of valves within support system. Incorrectly positioned
valves can restrict water flow and increase pressure with the system.
3. Contact pool servicer. Problem is not in PCS1 system.
