7250 Min. medium flow rate
The medium flow rate fell below the heat generator's minimum medium
flow rate
7251 Min. medium flow rate
The medium flow rate fell below the heat pump's minimum medium flow
rate due to defrosting or in cooling mode. After eliminating the cause of
the error, the controller must be restarted to reset the error.
7252
Heat pump alarm code
S20
Heat pump alarm code
7276 Restart required
Due to the changed system (setting / coding resistor), the controller has
to be restarted - disconnect it from the power supply for around 10 sec-
onds.

return temp. probe S15 Open contact - WE return temperature probe
7284
Short circuit - WE
return temp. probe S15 Short circuit - WE return temperature probe
7286 Rc coding error
A unique unit identifier could not be assigned using the coding resistor at
the Rc terminal.
7333
Negative temp. differ-
ence
The temperature difference when the heat generator is active is implau-
sible
