Especially in the night:
Readjust the setback with setting knob
. The scale indicates the setback in °C against the NORMAL temperature.
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 selector 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
