Interval Function - Viessmann VITOSOLIC 200 Installation And Service Instructions Manual

Interval function

■ Activation of this function in systems
with unfavourably located collector
temperature sensor. Consequently
delays in capturing the collector tem-
perature are prevented.

ON for a set period in a freely selecta-
ble interval.

from 07:00 ("Int ON") to 19.00 ("Int
OFF") h every 30 min ("Interval") for
