OPERATION & CHECKOUT PROCEDURES (CONTINUED)
MANUAL SYSTEMS: TURNING THE SYSTEM OFF
1.
Turn the pool pump off.
2.
Turn the three-way diverter valve so the “closed” indicator points toward
the solar feed side of the valve.

If isolating the collectors, close the isolation valve on the feed & return lines
after you are sure all the water has drained out of the collectors and plumbing.
4.
Turn the pool pump on to filter the pool as needed.
AUTOMATIC SYSTEMS
1.
Follow controller manufacturer operating instructions.
2.
Set the desired temperature setpoint in the controller.
3.
Turn the control mode to “auto”.

The controller will now control the operation of the solar pool heating system
by turning the three-way diverter valve via the actuator motor depending on
the temperature sensor readings.
•
The controller will send water to the solar loop when the roof
sensor is some number of degree warmer than the pool water
sensor and when the pool water is below the desire setpoint.
•
The controller will cease sending water to the solar loop when the setpoint has been
met or when the roof sensor reads a temperature lower than the pool water sensor.
5.
When the controller is in “auto” mode ensure that that all isolation valves are open.
During service or winterization make sure the controller’s solar function is set to
“off”, the system is drained,
