Menu item „Solar Collector“
Collector 64°C:
Current collector temperature
Circuit 1 Dom.water 40°C
Current temperature in the storage tank of the
solar circuit 1– in this case it is a dom.water
tank (for further details see chapter TC3-solar
collector).
Circuit 2 buffer 17°C
(only visible, if previously chosen in the basic settings
menu- s. operating instructions)
Current temperature in the storage tank of the solar circuit 2 – in this case it is a buffer memory
(for further details see chapter TC3-solar collector).
Circuit 1 running!
Here the status of the solar collector is shown, following notices are possible:
> „Circuit 1 running!“ or „Circuit 2 running!“<
Solar circuit 1 or solar circuit 2 running – meaning: solar collector 1 or solar collector 2 are being
heated.
> „Wait circ.1 priority!“ or „Wait circ. 2 priority!“<
As long as the maximum temperature of the primary solar storage tank is not reached, the collector
pump is stopped at regular intervals, to check if the collector temperature rises to the for the
higher-priority storage necessary temperature level.
> „Abs. too cold f. crc.1!“ or „Abs. too cold f. crc.2!“<
The primary solar tank can not be operated because the collector is too cold (too little solar
radiation) - instead the subordinated tank is served.
>„Circuit 1 Temp.Ok!“ or „Circuit 2 Temp.Ok!“<
The memory of the respective solar circuit has reached the predetermined maximum temperature.
This can be set in special settings menu (see "special settings menu”).
> „Absorber too cold!“ or „Absorber too hot!“<
The collector temperature is below the set minimum barrier or above the set maximum barrier (see
"special settings menu”).
Speed: 10%
(only visible if preselected in the basic settings menu – s. start-up menu)
Displays the current rotation speed of the collector pump, range 10-100% - the higher the value,
the higher the solar power.
154
Status of the internal sequence timer in seconds. Shows how long the current functioning phase is
still ongoing
Dem.Auto / Dem.Off!
Under certain circumstances the burner is locked. (see chapter TC3-solar collector).
Req.Off (=burner requirement off) => burner locked temporarily
Req.Auto (=burner requirement auto) => burner not locked
Heatmeter
(only visible if preselected in the basic settings menu – s. start-up menu)
The menu display "heat meter" can be accessed via this field.
