5.2. Setpoints
5.2.1. General
The setpoint of the NORMAL and the REDUCED temperature and of frost protection for
the plant / holiday mode are entered directly in °C room temperature. They are inde-
pendent of whether or not the control uses a room temperature sensor.
5.2.2. Frost protection for the building
The lowest valid room temperature setpoint always corresponds to at least the setpoint
of frost protection / holiday mode (setting on operating line 3), even if lower values have
been entered as the setpoints of the NORMAL and the REDUCED temperature (set-
tings on operating lines 1 and 2).
If a room temperature sensor is used and the room temperature falls below the holiday /
frost protection setpoint, ECO – if available – will stop OFF until the room temperature
has risen 1 °C above the holiday / frost protection setpoint.
5.3. Heating program
The heating program of the RVL470 provides a maximum of three heating periods per
day. Also, every weekday may have different heating periods.
Note:
The entries to be made are not switching times, but periods of time during which the
NORMAL temperature shall apply. Usually, these periods of time are identical to the
building's occupancy times. The actual switching times for the change from the
REDUCED to the NORMAL temperature, and vice versa, are calculated by the optimi-
zation function, provided it is activated. Using the setting "1-7" on operating line 4, it is
possible to enter a heating program that applies to all days of the week. This simplifies
the settings: if the weekend settings differ from the other weekday settings, first enter
