Energy-efficient heating with
the RVP201/211 heating controller
Operating Instructions
You want to switch the heating on
1. Is the plant ready to operate? Check the mains
switch.
2. Check the time of day and – with the 7-day time
switch – the weekday. Make readjustments, if neces-
sary (refer to the following section).
3. Move the operating mode selector to the required
Auto mode.
You want to set the clock
The switching dial may only be turned clockwise, never
anti-clockwise!
1. First, make a coarse setting:
Turn the switching dial slowly in clockwise direction
until the current time of day reaches the time indicator
(with the 7-day dial, also observe the weekday).
2. Now make the correct setting:
Turn the large hand until the time of day is correct.
Tip: The change from wintertime to summertime, and vice
versa, must be made manually.
You want to heat in automatic mode Auto
The controller has two Auto modes:
Automatic changeover between NORMAL tem-
perature and heating control OFF according to the
24-hour program.
Automatic changeover between NORMAL and
REDUCED temperature according to the 24-hour
program.
You want no heating for a certain
period of time
Move the operating mode selector to . The control is
switched off, but ready to operate.
Only with the RVP211: Select either
for control switched off, or
automatic d.h.w. heating, control switched off
Tip: Frost protection is ensured in all operating modes.
Meaning of LED “Override”
-“Override” flashes: A fault has occurred – refer to the
section covering operational faults
-“Override” steady on: Controller is controlled by the
room unit. The settings used are those made on the
room unit. There is no fault
You want to heat continuously Auto
-No setback: Select operating mode
-Continuous setback: Select operating mode
Tip: Do not forget to reset the operating mode!
Your rooms are too cold or too warm
Especially in mild weather:
Readjust the room temperature with setting knob . One
point represents a room temperature change of 2 °C.
Especially in cold weather:
Readjust the slope of the heating curve with setting knob :
-Room temperature too high: Reduce slope by about 0.2
-Room temperature too low: Raise slope by about 0.2

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
