18 - SOLAR
No. Display Description
18-01 Solar
Solar hysteresis
( 5) 5°
• Solar pump hysteresis
In order to activate the solar pump, the temperature of
the solar collector must exceed the “Temp. DWH tank
bot” by the amount of the set value. (0 - 20 °C)
18-02 Solar
Factor n solar pump
( 10) 10
• Multiplication factor for solar pump
Set the multiplication factor which, together with the
temperature difference (solar collector to hot water tank
bottom sensor), is used to set the speed of the solar
pump. (0 - 100)
18-03 Solar
Speed
Solar pump min.
( 30) 30%
• Minimum speed of the solar pump
Set the minimum speed for the solar pump.
(0 - 100 %)
18-04 Solar
Speed
Solar pump max.
( 100) 100%
• Maximum speed of the solar pump
Set the maximum speed for the solar pump.
(50 - 100 %)
18-05 Solar
Pause
Solar acc. pump
( 15) 15m
• Waiting time before restarting the solar accumulator
pump in order to check the available collector tempe-
rature (hot water tank priority).
(0 - 100 m)
18-06 Solar
Runtime
Solar acc. pump
( 15) 15m
• Runtime of the solar accumulator pump until the next
monitoring of the collector temperature.
(0 - 100 m)
18-07 Solar
Factor n
Solar acc. pump
( 10) 10
• Multiplication factor for solar pump
Set the multiplication factor which, together with the
temperature difference (solar collector to hot water tank
bottom sensor), is used to set the speed of the solar
pump. (0 - 100)
18-08 Solar
Speed
Solar acc. pump
( 30) 30%
• Minimum speed of the solar pump
Set the minimum speed for the solar pump.
(0 - 100 %)
18-09 Solar
Speed
Solar acc. pump max
( 100) 100%
• Maximum speed of the solar pump
Set the maximum speed for the solar pump.
(0 - 100 %)
18-10 Solar
Start time
solar pump at 100%
( 5) 5s
• Duration of start-up until solar pump reaches full
speed
Set the time for the start-up of the solar pump.
(0 - 15 s)
