3 Mounting and installation
3.1 Regulations
• Prior to installing the controller, the power supply must be turned off
• The connections for mains and low-voltage are separated
• The wiring must be made in compliance with the requirements of safety class II. This
means that sensor and mains cables may not be run in the same duct
3.2 Basic units RVS…
• Air circulation around the controller must be ensured, allowing the unit to emit the
heat produced by it.
A clearance of at least 10 mm must be provided for the controller's cooling slots
which are situated a the top and bottom of the housing.
The space should not be accessible and no objects should be placed there. If the
controller is enclosed in another (insulating) casing, a clearance of up to 100 mm
must be observed around the cooling slots
• The controller is designed conforming to the directives for safety class II mounted in
compliance with these regulations.
• Power to the controller may only be supplied when completely fitted. If this is not
observed, there is a risk of electric shock hazard near the terminals and through the
cooling slots.
• The controller may not be exposed to dripping water.
• Permissible ambient temperature when mounted and when ready to
operate: 0..50°C.
• Power cables must be clearly segregated from low-voltage cables (sensors)
observing a distance of at least 100 mm
• Boiler
• Control panel
• Housing for wall mounting

After manual control has been activated, a change to the basic display must be made.
There, the maintenance / special mode symbol
appears.
Press the info button to switch to info display “Manual mode“, where the setpoint can be
adjusted.
The chimney sweep function is activated by a short press (maximum 3 seconds) on the
chimney sweep button. This function produces the operating state required to make
emission measurements (flue gas).
The SLT test (SLT = safety limit thermostat) is activated by a long press (longer than 3
seconds) on the chimney sweep button. The button must be kept depressed during the
entire test. If released, the test will be aborted. The SLT test is shown on the display.
The test may only be made by qualified staff since the boiler temperature will be raised
above the maximum limits.

5.1.2 Programming
Setting principle
Settings that cannot be made directly with the operating elements require programming.
For this purpose, the individual settings are structured in the form of operating pages
and operating lines, thus forming practical groups of settings.
The following example shows how to set the time of day and the date.
Example: “Setting the time of day“
• Press ESC to go one step back at a time, readjusted values are not be adopted
• If no setting is made for 8 minutes, the display returns automatically to the basic
display
• Operating lines may be hidden, depending on the type of controller, the configuration
made and the user level

The heating curve is used to generate the flow temperature setpoint, which is used to
maintain a certain flow temperature level depending on the prevailing weather
conditions. The heating curve can be adjusted with a number of settings, thus matching
heat output and room temperature to individual needs.
As the heating curve slope is raised, the flow temperature increases the quicker the
lower the outside temperature or, in other words, if the room temperature is not correct
at low outside temperatures but correct at higher outside temperatures, the heating
curve slope requires readjustment.
Increase adjustment: Raises the flow temperature, especially when outside
temperatures are low.
Decrease adjustment: Lowers the flow temperature, especially when outside
temperatures are low.
The programmed heating curve is based on a room setpoint of 20°C. If the room
setpoint is adjusted, the heating curve automatically adapts to the new value.

limit
Parallel displacement of the heating curve is used to change the flow temperature
evenly across the entire outside temperature range or, in other words, if the room
temperature is always too high or too low, a readjustment must be made with the help
of the parallel displacement.
Adaptation of the heating curve is used by the controller to automatically adapt the
heating curve to the prevailing conditions. In that case, a readjustment of heating curve
slope and parallel displacement is not required. It can only be switched on or off.
To assure this function, following must be observed:
A room sensor must be connected.
•
•
The ”Room influence“ setting must be selected between 1 and 99
•
There should be no thermostatic radiator valves in the reference room (mounting
location of room sensor) (if such valves are present, they must be set to their fully
open position).

Types of compensation:
When a room temperature sensor is used, there is a choice of 3 different types of
compensation.
Setting Type of compensation
− − − % Pure weather compensation *
1…99 % Weather compensation with room
influence *
100 % Pure room compensation
* Outside sensor required.
The flow temperature is calculated via the heating curve, depending on the compsite
outside temperature.
This type of compensation calls for a correct adjustment of the heating curve since in
that case the control gives no consideration to the room temperature.
Deviations of the actual room temperature from the setpoint are acquired and taken into
account when controlling the temperature. Heat gains can thus be considered,
facilitating more accurate room temperature control. The authority of deviation is set as
a percentage figure. The better the reference room (correct room temperature, correct
mounting location, etc.) the higher the value can be set.
•
Example:
Approx. 60 % Good reference room conditions
Approx. 20 % Unfavorable reference room
To activate the function, following must be considered:
•
A room sensor must be connected.
•
“Room influence“ must be set to a value between 1 and 99 %.
There should be no thermostatic radiator valves in the reference room (mounting
•
location of the room sensor). (if such valves are present, they must be set to their
fully open position).

Boost heating is used to reach the new setpoint more quickly when switching from the
Reduced setpoint to the Comfort setpoint, thus reducing the heat-up time. During boost
heating, the room temperature setpoint is raised by the value set here. A higher setting
leads to shorter heat- up times, a lower setting to longer heat-times.
• Boost heating is possible with or without room sensor.

• Function with room sensor:
When using the room sensor, the function keeps the heating switched off until the room
temperature has dropped to the level of the Reduced setpoint or the frost level.
When the room temperature has fallen to the Reduced level or the frost level, the
heating circuit pump will be activated and the mixing valve will be released.

long at low outside temperatures. When the Reduced setpoint is raised, the rooms are
prevented from cooling down to too low levels, thus shortening the heating up time
when changing to the Comfort setpoint.

due to requests from other heat consumers (mixing heating circuit, DHW charging,
external heat demand), or a parameterized minimum boiler temperature. As a result of
this too high flow temperature, the pump heating circuit would assume excessive
temperatures.

* Outside sensor required.
The flow temperature is calculated via the cooling curve as a function of the composite
outside temperature.
This type of compensation requires correct adjustment of the heating curve, since in
this case, the control does not take account of the room temperature.
The deviation of the actual room temperature from the setpoint is measured and taken
into account when controlling the temperature. In this way, account is taken of room
temperature deviations, to facilitate more accurate room temperature control. The effect
of the deviation is set as a percentage figure. The better the reference room (correct
room temperature, correct mounting location, etc.) the higher the value can be set.
Room compensation only
Room temp limitation
Example:
•
Approx. 60 % Good reference room conditions
Approx. 20 % Unfavorable reference room
To activate the function, following must be considered:
•
A room sensor must be connected.
•
The ”Room influence“ setting must be selected between 1 and 99
•
There should be no controlled valves in the reference room (mounting location of
the room sensor) (If such valves are installed, they must be set to their fully open
position).
The flow temperature is controlled depending on the room temperature setpoint, the
current room temperature and the progression of the room temperature. For example, a
slight increase of the room temperature causes an immediate drop of the following
temperature.
To activate the function, following must be considered:
•
A room sensor must be connected.
•

2065 Charging priority solar
•
No:
Swimming pool heating through solar charging does not give consideration to any
priorities. If the storage tank charging priority (operating line 3822) is also deactivated,
the swimming pool is heated alternately with the storage tanks, the temperature
increase being 5 °C.
•
Yes:
Swimming pool heating through solar charging is given priority. This also applies if a
storage tank with charging priority (operating line 3822) would have to prefer other heat
exchangers.
If no Hx inputs are used to enable the swimming pool, the swimming pool priority is
determined by the parameter setting. The swimming pool is always enabled for solar
heating.

If the swimming pool is enabled via one Hx input, the swimming pool priority is
equivalent to the parameter setting. Solar heating must now be enabled via the Hx
input.
If two Hx inputs are used to enable the swimming pool, the swimming pool takes priority
when both Hx inputs are enabled. If only one Hx input is enabled, the swimming pool
priority is determined by the parameter setting. If none of the Hx inputs are enabled,
solar heating of the swimming pool is deactivated.

Economy mode can be selected from menu ”Service/Special operation” (operating line
7139).
In Economy mode, the boiler is operated as follows:
Off: Remains locked
DHW only: Boiler will be released for DHW charging
On: Always released.
To ensure long on times, the heat source keeps operating until the buffer storage

In normal operation, minimum limitation of the boiler temperature is the lower limit value
of the controlled boiler temperature setpoint, depending on the boiler’s operating mode.
In normal operation, maximum limitation of the boiler temperature is the upper limit
value of the controlled boiler temperature setpoint and, at the same time, setpoint of the
electronic limit thermostat (TR).
The setting range of setpoint minimum and setpoint maximum is limited by the setpoint
of manual operation.

Automatic changeover of the heat source enables a lead boiler change at certain
intervals. The boiler sequence changes when the selected time has elapsed.
When switching on automatic changeover, heat source 1 (T2) is always started up as
the lead boiler.

The restart lock prevents a deactivated heat source from being switched on again. It is
released again only after the set time has elapsed. This prevents too frequent switching
actions of the heat sources and ensures stable plant operating states.
Correct adjustment of the switch-on delay ensures that plant operating conditions will
be stable. This prevents too frequent switching actions of the boilers (cycling).
In the case of a DHW request, the delay time is fixed at 1 minute.

With automatic source sequence changeover, the boiler loads in a cascade can be
influenced by defining the order of lead and lag boiler.
Fixed order
Setting - - - defines a fixed order. In that case, the lead boiler can be selected on
operating line 3544; the other boilers are then switched on and off in the same order as
the LPB device addresses.
Order according to the number of operating hours
On completion of the number of hours set, the boiler sequence in the cascade changes.
It is always the boiler with the next higher device address which assumes the role of the
lead boiler.
