Programming Holiday Schedule (with RTC, only)
The holiday schedule programming is used to program each
day of the year (01.01 ... 31.12.) as a holiday (day type = H1,
H2 or H3) or as a normal day (day type = H0 is default).
+ -
Pushing the or button during the first step of the holiday
programming (see Fig. 16) toggles between all programmed
holidays (≠ H0) and displays them (type and date).
If none of the 365 days of a year is programmed to be a
holiday, the actual date is displayed, marked as normal day
(H0).
Pushing the SET button selects the displayed holiday and
enters the adjustment for date and day type.
To program a new holiday, select any holiday, adjust date
(and holiday type if necessary) and confirm the changes by
pushing the SET button. To reset a holiday to normal day, day
type H0 has to be set for the specific day.
Pushing the SEL button returns to the selection mode,
ignoring adjustments which have not been confirmed by the
SET button.

Interpreting Error Messages
Different analog input errors can be identified by the controller
(Error handling). The defective analog input (T1, T2, T3 or
X ) will be displayed in the standard display mode (see Fig.
wrh
17) after the corresponding value is selected.
NOTE: For the external CPA/SPA potentiometer input, no
error message is indicated if the potentiometer or
wiring is defective. In this case, for control point or
setpoint calculation, the following values are used:
• for CPATYP 0, 1 or 2 ⇒ CPA value = 0
• for CPATYP 3 ⇒ SPA value = control parameter W1
