Errors are saved in the Datamanager 2.0 and can be sent via Solar Web.
Possible error outputs (as of 07/12/2015):
Cause
The load on L1 is higher than 3
kW. Short circuit on L1.
Current on L2 is greater than 16 A.
Current on L3 is greater than 16 A.
No current flowing through L1/L2/
L3. L1/L2/L3 of HE 1 faulty. Phase
L1/L2/L3 interrupted.
The load on L1 is higher than 3
kW. Short circuit on L1.
Current on L2 greater than 16 A.
Current on L3 greater than 16 A.
No current flowing through L1/L2/
L3. L1/L2/L3 of HE 2 faulty. Phase
L1/L2/L3 interrupted.
Relay R2/R3 sticking.
TS input resistance less than 200
Ohm. No PT1000 TS connected.
TS faulty.
No TS connected
(Input resistance greater than
2000 Ohm). TS is activated
(should be deactivated). TS cable
faulty. TS faulty. No PT1000 TS
connected.
ES is switched off/faulty. (922
only). TS was incorrectly installed.
Heating system is incorrectly
dimensioned (excessive hot water
consumption, etc.) HE/TS faulty.
ES switched off/faulty. ES not con-
nected to Ohmpilot. TS incorrectly
installed. Heating system incor-
rectly dimensioned (excessive hot
water consumption, etc.) TS faulty.
I=Inverter ES=External source (e.g. gas-fired heating)
Solution
Check heating element 1.
Check wiring.
Check HE 1 and replace if
necessary.
Check L1/L2/L3. Check L1/
L2/L3 connections.
Check HE 2.
Check wiring.
Check HE2 and replace if
necessary.
Check L1/L2/L3. Check L1/
L2/L3 connections.
Replace Ohmpilot.
Check cable and connections
on TS cable. Replace TS.
Connect TS to device. Deac-
tivate TS via the website (if
no sensor is required). Check
TS cable. Replace TS.
Switch on ES (922 only).
Install TS above the HE (in
protective tube). Deactivate
legionella prevention via the
website. Replace HE/TS.
Switch on ES. Connect ES
to relay 1. Install TS above
the heat battery of the ES.
Check the target temperature
setting. Replace TS.
