Especially in the night:
Readjust the setback with setting knob
. The scale indi-
cates the setback in °C against the NORMAL tempera-
ture.
Tip: Each time you make a room temperature readjust-
ment, wait two days; the controlled system needs
time to adapt.
Tip: Do not forget objects that are sensitive to low tem-
peratures, such as plants.
You want to change the heating periods
For digital time switch: please refer to separate instructions.
Set the periods of time for the NORMAL temperature and
REDUCED/OFF with the switching dial using the tilting
riders:
- For periods of time with NORMAL temperature:
Tilt riders outward
- For periods of time with REDUCED temperature or
OFF: Tilt riders inward
Tip: Before making any settings: Prepare a heating
schedule.
Only with the RVP211: You want to
change the DHW temperature
Readjust the DHW temperature with the setting knob .
Recommended setting: 55 to 60 °C.
Tip: Excessive temperatures lead to more scale buildup.
Your heating system responds in an
unusual manner
?
- In the event of a power failure, the clock will make up
for the lost time when power returns.
You can cancel catching up by briefly setting the selec-
tor to
and then back again to the required operating
mode. Then, readjust the clock
- Temperature does not change: Check the operating
mode; automatic setback and heating up with only one
Auto mode
- Room unit (if present) is inactive: Check the controller's
operating mode – it must be an Auto mode!
- Required temperature is reached either too early or to
too late: Change the 24-hour program
Tip: Well insulated buildings have a great thermal inertia.
What to check in the case of operational
faults
- Are all fuses of the plant in order?
- Is sufficient fuel in the tank?
- Have the controller settings (e. g. the setpoints) been
changed?
- Does the green LED “Override” flash? Reason: Flow or
boiler temperature sensor faulty / not connected, or
outside and room temperature sensor
faulty / not connected. Select operating mode
and
call in your heating engineer
- Has the burner gone to lockout? If yes, press the reset
button
Energy saving tips
- Do not allow room temperatures to exceed 21 °C dur-
ing the day
- Air the rooms for only short periods of time, but with the
windows fully open
- Set the thermostatic radiator valves in unoccupied
rooms to the frost protection position
- Make certain there are no curtains, furniture, etc., in
front of the radiators
- Close shutters and blinds whenever possible
- Check the consumption of heat on a regular basis
