Weather Compensation Curve; System Protection And Error Codes - Earth Save Products SOLIS 11 Installation And User Manual

4.4.7

Weather compensation curve

The weather compensation curve is set by parameter 46 with permissible values from 30 to 50. The
default value is 45. This means that the Solis will automatically adjust the flow temperature as the
ambient temperature drops, to a maximum flow temperature of 45°C. See graphs above.
Likewise, if cooling has been enabled by the factory, the flow temperature will automatically decrease as
the temperature increases as defined in parameter 45.
decreasing the value moves the curve down the temperature scale. Permissible values are -15 to15.
The default value is 0.

4.5 System Protection and Error Codes

In the unlikely event of a fault, the controller will show an error code consisting of a letter (E,F or P) and a
number. The controller will also show a code is encounters circumstances such that it needs to shut down
for safety reasons. The most common codes are:
Code Meaning
E1 Compressor overheat or
discharge high temp protection
E2 Outdoor air temp sensor error
E3 Pipe or return air temp sensor
error
E4 AC return water temp sensor
error
E5 AC leaving water temp sensor
error
E6 DHW temp sensor error
E7 Solar water temp sensor error
E8 fan coil high temp protection
E9 System anti freeze twice
EA DHW anti freeze twice
EB Indoor refrigerant pipe sensor
error
EC Water source inlet water sensor
error
ED Water source leaving temp
sensor
EE Water source anti freeze
