In addition to the basic function of the controller it is 
possible to further protect the system against overheating
via a passive and or active protection function. In the basic
function (setting 0) the solar pump is switched off if the
“

Tank Temp. Maximum

” or “

Calorifier Temp. 

Maximum

” is exceeded.  The pump is also switched off if

the collector temperature exceeds 120°C. The pump
switches on again once the collector has cooled to 80°C.

1. Passive protection:

If the collector temperature increases to above 80°C
and if the tank or calorifier temperature is above
“...Temp. Maximum” the solar pump is operated at
100%. The tank or calorifier is now loaded up to a 
max. of  95°C, independent of the setting “...Temp. 
Maximum”. Switch off again occurs if the collector 
temperature exceeds 120°C or the switch off condition 
“...Diff. Off” has been achieved. Switch on occurs at 
80°C collector temperature, or when the tank/calorifier 
temperature drops to 92°C, without the collector 
temperature exceeding 120°C.

2. Active protection:

The following two active protection functions are 
possible:

2.1  Release cooling function as soon as the collector

protection temperature and the “Tank  Temp. 
Maximum” or “Calorifier Temp. Maximum” has 
been reached.

2.2 Release cooling function as soon as the

“Tank Temp. Maximum” or “Calorifier Temp. 
Maximum” has been reached.

Once the cooling function has been released, and if the 
collector temperature falls 8K below the lower tank or
calorifier temperature, the solar pump is started and 
the tank/calorifier is discharged. Discharge is stopped 
as soon as the collector temperature drops to  4K 
above the tank/calorifier temperature or if it drops 15 K 
below the max. tank/calorifier temperature.

The setting 1, 3 or 5 must not be made in 
conjunction with a tank or calorifier, who’s
permissible maximum temperature lies below
95°C. The setting is also not permitted, if the 
DHW pipework has not been equipped with
scald protection.

7.1 Collector protection 

DANGER

If the cooling function is not required, setting 0 or 1 should
be selected. 

Note:

• On hydraulic variations with plate heat 

exchanger both pumps are activated.

• On hydraulic variations with tank cascade

only the tank with the lowest priority emptied.

Variation: 1…45, 50…84
