| Function | Explanation |
| F1: Max Tank Temp | Once this temp is reached the solar ciruculation pump is turned off to prevent further heating of the tank. Error 1 displayed. |
| F2: Min Tank Temp | If the bottom of the tank drops below this temp error reporting occurs (Error 2). |
| F3: Delta-T On | The temp differential required for solar pump operation to occur. |
| F4: Delta-T Off | The temp differential at which the solar pump turns back off. |
| F5: Collector Startup | The minimum collector temp before Delta-T operation can begin. Prevents pump circulation when minimal heat potential is present. |
| F6: Freeze On | The circulation pump is switched on when the manifold drops below this temp - this is the standard freeze protection method for mildly cold areas. |
| F7: Freeze Off | The circulation pump is switched off once this temp is reached. |
| F8: Collector Max | If this temp is reached Error 6 is displayed. This function should be turned off if function 1 is operational. |
| F9: Collector Min | If the collector drops below this temperature Error 7 is displayed - indicating that freeze protection has failed (or is incorrectly set). |
| F10: Boost On | Once the top of the tank drops below this set temp, power is supplied to the 2nd relay which can active a circulation pump for boosting (eg gas tankless heater) |
| F11: Boost Off | Once the top of the tank reaches this temp the 2nd relay turns off. |
| F12: Excess Heat ON | If the top tank temp reaches this level power is supplied to the 3rd relay, allowing heat to be drawn from the tank for other uses (pool, spa, central heating) or for heat dissipation to prevent tank overheating. |
| F13: Excess Heat OFF | Once the top tank temp drops below this level the power supply to the 3rd relay is stopped. |
| F14: System Reset | Defaults to most common system settings. |
| F13: Tank Cooling Temp | If the bottom of the tank reaches this high temperature the pump will circulate at night to cool the tank down. |
| F13: Tank Cooling Delta-T | The negative Delta-T value that allows the pump to turn on to cool down the system. |
|
Notes: - All functions have adjustable temperature ranges. - Exceeding the upper or lower limit of any function turns it off. |
