1.1 Operating conditions

With the room thermostat VRT-PZA, the temperature for
the heating periods „day" and the drop periods
„night" can be controlled independently of each other.
From the beginning to the end of a heating period, the
room is controlled at the „daytime temperature" set by
you. Between these heating periods, i. e., during the
drop periods, the room thermostat VRT-PZA controls
the room temperature at the „night-time temperature"
set by you.
(Fig. 1, p. 3)
Heating periods can be programmed individually for
every day and together for several days. In addition,
the factory-set basic programme can be readjusted at
any time.
With the party key (4), it is possible to continue the
heating operation during the following drop period
even if the current heating period is terminated. If, for
example, the party key was pressed during the last
heating period of a day, the heating system continues
operating at day-time temperature until the end of the
first heating period of the following day.
