Manual Mode - Compit SOLARCOMP 911 Installation And Operating Instructions Manual

Basic settings
Set temperature of DHW tank. If the tank temperature (T2 or T3)
exceeds this value, the loading stops.
T1-T2 difference; when exceeded, the tank loading pump is switched
on.
If T1-T2 difference drops below this value, the tank loading pump will
switch off.
Set temperature of tank no. 2. Heat transfer between the tanks is
disrupted when temperature T4 exceeds the value set for this
parameter by 1°C. It can be started again when temperature T4 drops
1°C below the parameter value.
Temperature difference T3-T4, exceeding of which activates P2
pump.
If temperature difference T3-T4 drops below this value, P2 pump
switches off.
Enabling of a sound alarm.
0 – sound alarm disabled, 1 – sound alarm enabled.

Manual Mode

In order to switch to manual mode, set the code to 105 and press
display will show MAN. Using arrow keys you can change P1 pump speed.
controls P2 output. Press button again to exit manual mode.
Holiday Mode – Heat Discharge from the Tank
This mode, which is user-activated, is used to cool the tank if hot water is not used
(e.g. the house is uninhabited). This prevents excessive heat accumulation and the risk of
system overheat. Cooling of the tank takes place when the sun goes down (late evening
and night). If solar panel temperature T1 drops 2°C below tank temperature T2, circulation
pump P1 is activated and the heat accumulated in the tank is radiated by the collector.
Cooling of the tank will stop if its temperature drops below 10°C.
If the collector temperature exceeds the tank temperature, P1 pump is switched off. If
HOLIDAY MODE is selected in variant no. 2 (with heating coil), the coil's operation will
also be blocked.
To select holiday mode, access collector temperature reading and hold down
button for three seconds.

To disable holiday mode, access collector temperature reading and hold down
button for three second – the controller will resume normal operation. Active disinfection
function (LEGIONELLA) in HOLIDAY MODE increases the tank temperature up to a set
value every 7 days.
Malfunctions
If a fault occurs, the controller will display a flashing symbol presented in Fig. 9.

The error code can be identified by pressing
following errors:
AWR 1 Collector maximum temperature exceeded (set in KMX)
AWR 2 Collector switch-off temperature exceeded (set in KOF)
AWR 3 AWR 1 + AWR 2
AWR 4 Tank switch-off temperature exceeded (set in ZOF)
AWR 5 AWR 4 + AWR 1
AWR 6 AWR 4 + AWR 2
AWR 7 AWR 4 + AWR 2 + AWR 1
AWR 8 Sensor failure
AWR 9 AWR 8 + AWR 1
AWR 10 AWR 8 + AWR 2
AWR 11 AWR 8 + AWR 2 + AWR 1
AWR 12 AWR 8 + AWR 4
AWR 13 AWR 8 + AWR 4 + AWR 1
AWR 14 AWR 8 + AWR 4 + AWR 2
AWR 15 AWR 8 + AWR 4 + AWR 2 + AWR 1
If all the temperature values are within appropriate limits, OK will display instead of an
error code.
In the case of a sensor failure, check temperature readings. If the sensor is damaged,
a relevant temperature reading will be replaced by „Err". Check if the sensor is connected
appropriately or replace the sensor.
