The solar circuit pump stops
if the collector temperature
reaches 266°F (130°C)
(maximum collector temperature
to protect the system
components)
Temperature differential for
stagnation time reduction
(reduction in the speed of the
solar circuit pump to protect
system components and heat
transfer medium) 5 K.
Collector frost protection
function switched off
t monitoring switched on.
No flow rate captured in the
solar circuit, or flow rate too
low.
Night circulation monitoring
switched on.
Unintentional flow rate is
captured in the solar circuit
(e.g. at night).
Calculation of solar yield
with Viessmann heat transfer
medium
The flow rate in the collector
circuit at the maximum pump
speed is set to 1.8 USG (7 L/
minute).
Target temperature control
switched off (see coding
address "11").
