thyristors switch through the positive or negative sine half-
wave as long as a switch-on difference exists. The triac
switch switches off when the temperature falls below the
switch-off difference.
System Protection
In order to protect system components like solar circulation
pump, 2-/3 way valves etc. that are installed in the solar cir

cuit against excess temperatures,solar charging is stopped
entirely as soon as a set temperature limit is exceeded at
sensor T1 (collector), even when charging would still be
possible due to the temperature difference between sen

lower half) has to be activated, otherwise the solar circula-
tion pump will switch off again.
The rise in temperature at sensor T1 (collector) is measured
again immediately after the last runtime of the pump.
System Messages
The system messages for interrupted or shorted-out sen-
sors are represented by symbols on the display.
Triac
The Triac is an electronic on/off switch for the 230 V outputs
of the SUNGO controllers.
Function: A triac switch consists of 2 diodes which can be
switched anti-parallel (= antiparallel thyristors). The
