Solar Heat-Pump Hybrid - G&F Manufacturing Gulfstream HE125RA Install & Operation Manual

Solar-Heat Pump Hybrid System
Install Instructions
This option will allow the Heat Pump to monitor the performance of the pool's
solar heating system, and will automatically divert the water away from the
solar to prevent overheating or cooling of the water. A roof sensor and solar
actuator are required (See Solar Wiring Diagram).
Installing A Hybrid System:
Installing the Solar after the Heat Pump
:(Factory Recommended)
This form of the Hybrid System is the recommended installation from the
factory. Plumbing the Solar system after the heat pump will prevent from
having flow issues, and from getting an incorrect current water temperature.
Installing the Solar before the Heat Pump:
If you choose to install the solar before the heat pump you need to make
sure that you install a 10k water temperature sensor on the water line after
the filter and before the solar. Otherwise you will not get the current water
temperature on the display screen. This will cause the heat pump to shut off
before it reaches the set point. The new sensor must be attached to the
board on the spades where the current WTS is attached.
Enabling the Solar Control:
Press and hold the UP and the DOWN arrows until the service menu appears.
Use the "MODE" button to scroll, when you see "SOLAR CONTROL", Press the
UP or DOWN arrow to "ENABLE". Do not touch anything else. The board will
automatically return you to the main screen.
Setting Temperatures for Heat pump and Solar:
To set the temperature, press "Mode" button until "Pool- Solar Heat" displays
on screen. Press the UP arrow until "POOL TEMPERATURE SETPOINT"
displays on screen. Once you set the desired pool temperature, then press
the "Mode" button so that the screen reads "POOL SOLAR SETPOINT", set the
temperature desired for the solar. The temperature set point for the heater
can be lower than solar, but cannot be set higher; the heat pump will run
until the set point for the heater is satisfied.
WARNING:
Make sure if you are installing the heater to an exsiting solar system, Please
check the condintion of the the low voltage wires.
