In caso di lunghi periodi di assenza durante il periodo invernale
regolare la testa termostatica nella posizione antigelo
❄
corrispondente ad una temperatura ambiente non inferiore a 7°C.
Durante il periodo estivo invece è consigliabile regolare la testa
termostatica nella posizione 5, ovvero con valvola tutta aperta.
In the case of long periods of absence specially during winter, set
the thermostatic head to the frost protection position
❄
corresponding to a room temperature of not less than 7°C.
During the summer season instead it is advisable to set the
thermostatic head to the n° 5 position, with the valve fully open.
Bei längerer Abwesenheit während der Heizperiode ist die
Einstellung Antifrost
❄ (entspricht einer Raumtemperatur nicht
unter 7°C) zu wählen.
Außerhalb der Heizperiode ist es ratsam, den Thermostat-Kopf auf
Position 5 einzustellen, damit das Thermostatventil vollständig
geöffnet ist.
Pendant les périodes d’absences prolongées en hiver, régler la tête
thermostatique sur la position “antigel”
❄ qui donnera une
température d’ambiance supérieure à 7°C.
Pendant l’été, il est conseillé de positionner la tête thermostatique
sur la position 5.
En caso de largos períods de ausencia durante el período invernal,
regular el cabezal termostático en la posición antihielo
❄
correspondiente a una temperatura ambiente no inferior a 7°C.
Durante el verano es aconsejable regular el cabezal termostatático
en la posición 5 que es con la válvula totalmente abierta.
Em caso de longos períodos de ausência durante o Inverno
deve-se regular a cabeça termostática na posição anti-gelo
❄
correspondente a uma temperatura ambiente não inferior a 7°C.
Durante o Verão é aconselhável regular a cabeça termostática na
posição 5, ou seja com a válvula toda aberta.
Tijdens de winterperiode is het bij lange afwezigheid aangeraden om
de thermostaatknop in te stellen op de vorstbeveiligingsstand
❄ die
overeenstemt met een omgevingstemperatuur niet lager dan 7°C.
Tijdens de zomerperiode daarentegen is het aangewezen de
thermostaatkop in te stellen op cijfer 5, ofwel met volledig geopend
ventiel.
