Parameter
Room sensor adaptation
The actual display can be vari ed by
± 5 K in order to adapt the room temperature displ ay to the instal lation c onditions or other therm ometers. T he c or rected display value is used in the
calculations for all relevant functions.
Display
This parameter all ows you to set
whether the current desi r ed r oom temperature is shown on the display.
Warm-up optimisation
War m-up optimi sation determines the
optim um advance time of star t of
heating. T he tim e advance ensures
that the heated r ooms hav e r eac hed
their desir ed temperature at the switchon tim es of the heating times.
Display: Last t ime advance required
Setting: Maximum time adv anc e
Control I/0 <=> Proportional
Selection between two-point and proportional c ontrol.
CONTROL I/0
Heating m ode starts if the actual tem-
perature drops below the room tem perature by the displayed amount [K].
If t he temperat ur e is exceeded by t he
amount [K ], Heati ng mode ends. A
minimum switch-on/switch-off time can
be set with the delay set ting.
PROPORTIONAL control
Heating m ode is switched on for a per-
centage (50 %) of the adjustable cycle
tim e as a functi on of the deviation between the measured and desired t emperature of the room. The hysteresis
setting allows you to set an allowable
deviation from the desired tem perature. This avoid short On times of the
boiler.
CONTROL OFF
No control function. The relais switches
only ti me dependent.
Heating/Cooling
The control ler can also be used f or
controlled cooli ng of rooms. If the
"Cooling" function is selected, the connected cooling system is closed if the
desired temperature is ex ceeded by
the set hysteresis and is opened if the
actual temperature dr ops bel ow the
desired temperature. In P roportional
mode, the r elay is also switched as a
function of the control devi ation. T he
greater the set desir ed temperat ur e is
exceeded at t he instant of comput ation, t he longer the cooling system r emains active.
Telephone switch/window contact
Telephone switch: The controller
switches to Heating mode for as long
as the contact between ter minal s 3/4 is
closed.
Window contact: The controller
switches to Frost-prot ec tion m ode
for as long as the c ontact between
terminals 3/4 is i nterrupted.

Room temperature
This parameter all ows you to progr am

for the three heating tim es. The entered value is set by t he c ontrol on the
basis of the integrated room sensor.
ECO-TEMP
The reduced temperature or economy
temperat ure represents the temperature to which the system stabilises outside the heating tim es, e.g. during the
nighttime or during ECO mode.
Holiday
You can use the controller’s Holiday
program during the holiday period. The
duration of the holiday and the hol iday
start are entered in days. The Holiday
program is always activated at 12. 00
hours and always ends at 24.00 hours
of the last day of the holiday .
!
If t he holiday period is entered before 12.00 hours, the Holi day pr ogram start s on the day of entry ( S HOLIDAY= 00; with S-HOLI DA Y =05
in 5 days). If the hol iday period is
entered after 12.00 hours, the pr ogram start s on the next day at 12.00

later.
The control ler switches to Standby
