Start function (ideal for tube collectors)

 

In the morning, solar power systems sometimes do not “start” quickly 

enough because the warm heat transfer medium does not reach the collector sensor. Flat 
collector panels and 

forced-circulation vacuum tubes

 generally lack sufficient gravitational 

force.  

The start function tries to release a rising interval while the collector temperature is con-

stantly monitored. The computer first determines the weather conditions based on the con-
stant measurements of the collector temperatures. It thus determines the right time for a 
short rinsing interval to maintain the actual temperature for normal operation. 

When the radiation sensor is used, the solar radiation is used for the calculation of the start 

function (radiation sensor 

GBS 01

 - non-standard accessory). 

The start function is deactivated ex works.  

 

 

                                                               

    

 

 

A 1

 – 

Activation

 of start function. 

A 1

 means start function active, 

A 0

 = 

start function deactivated 

ew

 = A 0 

 

F 3

 – Connection of a radiation sensor to sensor input 

T3

F 0

 means, 

that the average temperature (long-term mean regardless of the weather) 
is calculated instead of the radiation sensor value. 

ew

 = F 0 

 

c20

 – 

radiation threshold

 200W/m², above which rinsing is allowed. 

Without a radiation sensor, the computer calculates the necessary tem-
perature increase for the long-term mean that launches rinsing from this 
value.  

ew

 = 15 

 

r15

 – 

Pump runtime

 (rinsing time) in seconds. During this time, the 

pump should have pumped roughly half of the content of the collector’s 
heat transfer medium past the collector sensor. 

ew

 = 15 

 

i35

 – Maximum allowable 

interval

 between two rinses in minutes (exam-

ple: 35 minutes). This time is automatically reduced according to the 
temperature increase after rinsing.  

ew

 = 20 

 

n 4

 – 

Number of start attempts

 (= counter). The system is automatically 

reset for a start attempt if the last start attempt was more than four hours 
ago.
