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). This may be due to a failure of the auxilliary
boosting system. |
| F3:
Delta-T On |
The temp differential
required for solar pump operation to occur. ie. when
there is solar heat in the collector. |
| 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. May prevent
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 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 OFF |
Once the top tank temp
drops below this level the power supply to the 3rd relay
is stopped. |
Notes:
- All functions have adjustable temperature ranges.
- Exceeding the upper or lower limit of any function
turns it off.
- Errors 3,4 & 5 are for sensor 1,2 & 3 failure
respectively.
