menu 6.3 / 6.3.1 - 6.3.5
Two solar protection variants V1+V2 and an alarm function with additional
settings are available for the hydraulic systems with solar; these are explained
in more detail below.
Caution
Danger!
In variant V1 the storage tank or the swimming pool is heated up
over the Tmax value set under 10., which can lead to scalding and
damage to the system.
Caution
In variant V2 elevated standstill temperatures and the correspon-
ding system pressure are generated, which in some systems may
lead to damage.
The solar protection is switched off at delivery. Please consult the
operating instructions for the system components for information on
whether and what solar protection variants the system requires.
Col.-Alarm
If this temperature is exceeded at the collector sensor when the solar pump
is on a warning or error message is triggered. The red light
fl
ashes and the
corresponding warning appears in the display.
Kol.-Alarm - Einstellbereich: Aus/60°C bis 300°C / Voreinstellung : Aus
SPF variant V1
If the value “SPF T.on” is exceeded at the collector, the pump is switched on
to cool the collector. The pump is switched off if the value at the collector drops
bellow “SPF T.off” or the value “SPF Tmax stor.” is exceeded at the storage
tank or swimming pool. In systems with two storage tanks only the lower-priority
storage tank or swimming pool is used for heat dissipation.
SPF variant V1
If the value “SPF Ton” is exceeded at the collector, the pump is switched
off and not switched on again in order to protect the collector against steam
blasts, etc. The pump is only switched on again when the value at the
collector drops below “SPF Toff”.
SPF variant setting range : V1, V2, off/default setting : Off
SPF Ton setting range : from 60°C to 150°C/default setting: 110°C
SPF Toff setting range : from 50°C to 145°C/default setting: 100°C
SPF Tmax stor. setting range: from 0°C to 140°C/default setting: 90°C
