Collector excess temperature: Steam occurs in the system during standstill. When the
system automatically switches on again, the pump does not have enough pressure to raise
the fluid level above the highest point in the system (collector supply line). This represents a
considerable load on the pump when there is no circulation. This function allows the pump to
be blocked whenever the collector reaches a certain temperature (max �) until a second
settable threshold (max �) has been crossed.
ON / OFF Collector excess temperature limit ON/OFF (ex works = ON)
max � Temperature above which the outputs set are to be blocked
(ex works = 130°C)
Setting range: 100°C to 200°C in increments of 1°C
max � Temperature above which the outputs set are to be released.
(ex works = 110°C)
Setting range: 100°C to 199°C in increments of 1°C
