Level 5

The system cooling function aims to keep the solar system 
operational for a longer time. The function overrides the 
maximum store temperature to provide thermal relief of 
the collector fi eld and the heat transfer fl uid on hot days.
If the store temperature is higher than the adjusted maxi-
mum store temperature and the switch-on temperature 
difference 

DTCO

 is reached, the solar system remains 

activated or is switched on. Solar loading is continued until 
either the temperature difference falls below the adjusted 
value 

DTCF

 or the collector emergency shutdown tem-

perature 

CEM

 is reached.

If the system cooling function is active,   is shown on the 
display (fl ashing).

 System cooling

 CooL / OSYC

System cooling option
Adjustment range: ON / OFF
Factory setting: OFF

 COOL / DTCO

Switch-on temperature diff.
Adjustment range: 1.0 ... 30.0 K
Factory setting: 20.0 K

 COOl / DTCF

Switch-off temperature diff.
Adjustment range: 0.5 ... 29.5 K
Factory setting: 15.0 K

Note:

This function will only be available if the collec-
tor cooling function, the heat dump function, and 
the drainback option are deactivated.

 Store cooling

When the store cooling function is activated, the controller 
aims to cool down the store during the night in order to 
prepare it for solar loading on the following day.
If the adjusted maximum store temperature (

S MAX / 

S1MAX / S2MAX

) is exceeded and the collector tempe-

rature falls below the store temperature, the system will be 
reactivated in order to cool down the store.
Reference temperature differences are 

DT O

 and 

DT F

.

 COOl / OSTC

Option store cooling
Adjustment range: ON / OFF 
Factory setting: OFF

Note: 

If the temperature at the store sensor reaches 
95°C, all cooling functions will be blocked. The 
switch-on hysteresis is -2K.

  Cooling functions

Different cooling functions can be activated: system cooling, 
store cooling and heat dump.

If the heat dump function 

OHDP

 is activated, the selected 

relay is energised with 100%, if the collector temperature 
reaches the adjusted collector overtemperature 

OTCL

. 

If the collector temperature falls by 5 K below the adju-
sted collector overtemperature 

OTCL

, the relay will be 

switched off. 
A selection can be made between pump logic and valve logic 
(

OTPUM ON

 = pump logic, 

OTPUM OFF

 = valve logic). 

If pump logic is selected, the relay for solar loading switches 
off and the relay for heat dump remains switched on.
The relay for the heat dump function can be selected in the 

HDREL

 channel.

Note: 

The adjustable value 

OTCL 

is locked against 

the collector emergency temperature 

CEM 

by 10 K. The heat dump will only be available 
if the collector cooling function, the system
