3.3 Adjuster code 2

The adjusters with code 2 are

valid for all hydraulic variants!

You receive the code 2 from

your heating expert.

Unit Basic set.

Dat.:

8-05 Overheating protection on/off on -

If the temperature at the collector rises above the set collector maximum tempe-

rature (Adjuster 8-11) with the overheating protection active, solar charging will

be enabled independent of the set tank maximum temperature (Adjuster 8-59).

The set value for the speed control is determined by the temperature on the tank

sensor + setting value 8-64.

If the collector protection temperature Adjuster 8-10 or the tank protective

temperature (E8-60) is exceeded, solar charging is disabled.

8-09

Special heat capacity collector

fluid

on/off 4.1

kJ/

kg K

Special heat capacity of the collector fluid according to manufacturer’s

specifications.

8-10 Collector protective temperature 80÷130 130 °C

If the temperature at the collector sensor rises above the set value, solar char-

ging is disabled.

8-11 Collector maximum temperature 80÷130 95 °C

If the temperature at the collector sensor rises above the set values with the

overheating protection active (Adjuster 8-05), solar charging is enabled.

8-13 Frost protection function -50÷10 -50 °C

Deactivated if the setting is -50°C.

Solar pump is switched on if the temperature at the collector sensor < setting -

hysteresis.

Hysteresis 3 K is a given set value.

8-90

Error threshold for pump feed-

back signal

0÷200 100 %

The pump can be controlled. The controller measures the phase displacement

and compares it to the expected values.

Only for controller ES 5910 P / 5911 P. Error check is only carried out at

pump start-up.

0% = Only small deviations allowed

0 ÷ 199% = The larger the set value, the higher the allowed deviation

200% = Inactive, no pump error messages

8-91

Max. temperature difference

collector - tank

10÷80 50 K

If the difference in temperature between the collector and the tank temperature

rises above the set value when solar charging is active during the set time

(Adjuster 8-92), an error message (Err 61, 62, 63) is generated.

8-92

Waiting period error message

∆T collector - tank

0÷180 30 min

If the difference in temperature between the collector and the tank temperature

is too high when solar charging is active and during the set time, the error mes

sage is generated according to 8-91.

0 = Error message disabled
