Function (ECO-N):
The pipeline is usually supplied with a lowered
temperature required by the weather-guided heat-
ing control system. The utility water heater is
loaded at the maximum flow temperature set. To
do so, the heating water is re-channelled by a
valve to the utility water heater. The integrated
timer shifts this to non-productive times, where
the room heating unit is quickly interrupted.
Operating modes for the room heating unit
-
Off:
The room heating system is switched off.
-
Day/Night:
Heating operation according to clocked pro-
gramme. Normal temperature during the day
and reduced temperature at night.
-
Day/Off:
Heating operation according to clocked pro-
gramme. Normal temperature during the day
and switched off at night.
- Day:
Normal temperature continuously.
- Night:
Reduced temperature continuously.
- Manual:
Pump on; the valve is not controlled (emer-
gency operation).
(mask number) parameter (factory setting)
(01) Operating mode (Day/Night)
Select operating mode
(02) Number of heating periods (1)
The weekly programme has to be entered in the
form of heating periods. Each weekly programme
consists of the heating day, start and end. A
maximum of seven heating periods is available.
(03) Heating Period 1/Heating days (MON to
SUN)
Day or days on which the switching times apply.
Select the heating days with KEYS F1 (for Mon-
day) to F7 (for Sunday). Pressing the button once
Æ
selects the day, pressing the button again
Æ
drops the day.
(04) Heating Period 1/Start (6:00)
Time to switch from lowered temperature (or off)
to normal temperature.
(05) Heating Period 1/End (22:00)
Time to switch from normal temperature to low-
ered temperature (or off).
(06-23) Heating Periods 2-7
These depend on the number of heating periods
(see Mask 2), consisting of heating days, start
and end.
(24) Temperature of flow/at +5°C (43°C)
(25) Temperature of flow/at -15°C (64°C)
(26) Temperature Room Day (20°C)
Setting for temperature of room during daytime
operation.
(27) Temperature Room Night (15°C)
Setting for temperature of room during nighttime
operation.
(28) Night-time lowering of flow temperature
by (-6°C)
This temperature set is subtracted from the flow
temperature calculated for night-time lowering.
(29) Flow temperature; maximum (70°C)
The maximum limit for the flow temperature.
(30) ECOcircuit (YES)
The ECO automatic savings system makes the
heating switch on and off as required.
(31) Switch off below system temperature (NO)
Should the room heating unit group be switched
off when a minimum system temperature is fallen
short of?
(32) Frost protection function (YES)
With the frost protection function switched on, the
room heating unit is turned on when there is a
danger of frost.
(33) Carry off excess heat (NO)
If the PYROT is at risk of overheating, there is the
option of the excess heat being carried off. The
room heating unit adjusts to "Flow tempera-
ture/Maximum".
