Holiday mode
Holiday mode is enabled only by scheme 201 and 203.
Holiday mode is used in cases of longer absence from home when there is no consump-
tion of hot water for longer period (several days).
Pump is activated if temperature of collectors T1 reaches P2.2 value and stays ON until
the temperature of collectors drops below the P2.2 plus hysteresis (P1.18) or until the tem-
perature of tank T2 reaches the P2.4 value. In the night time (but also in the day time),
when the collector temperature T1 drops 20 K below tank temperature T2, the pump is
activated again to cool the tank by circulating the liquid between hot tank and colder collec-
tors. The cooling process is active until the tank temperature T2 drops to P2.4 value or until
the temperature difference T2
-
T1 is less than 15K.
Holiday mode is activated until selected date. After you have activated the Holiday mode,
choose the Holiday mode icon again. A new screen is displayed, where you can set the
date when the Holiday mode should be cancelled.
Each function can be at anytime cancelled by selecting icon .
Setting of PROTECTION OF MAX. COLLECTORS TEMPERATURE (S2.1)
and RECOOLING OF STORAGE TANK (S2.7) have no influence on Holi-
day mode operation.
The 20 K and 15 K temperature differences apply only if you do not change
the original factory setting. Generally, T
cooling ON
= P1.1+10 K and
T
cooling OFF
= P1.2+10 K.
