HVAC Products Safety notes 11. May 2007
3 Mounting and installation
3.1 Regulations
Electrical installation
Planning
Mounting location
• Prior to installing the units, power must be turned off
• The connections for mains and low-voltage are separated
• For wiring, the requirements of safety class II must be satisfied. Sensor and power
cables must not be run in the same cable 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 unit's cooling slots at the top
and bottom of the housing.
That 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 devices
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 must 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

5.1.2 Programming
Setting principle
Settings that cannot be made directly with the operating elements are made in the form
of 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

The heating curve is used to generate the flow temperature setpoint, which is used to
maintain a certain flow temperature 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.

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

* Outside sensor required.
The flow temperature is calculated via the heating curve, depending on the composite
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
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).
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.
• “Room influence“ must be set to 100 %.
• There should be no thermostatic radiator valves in the reference room (mounting

In the case of heating plant with pump heating circuits, the flow temperature of the
heating circuit can be higher than the flow temperature demanded by the heating curve,
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.

When priority for the swimming pool is activated (operating line 2065), the swimming
(1)
pool is charged before the storage tanks.
If the preferred storage tank cannot be charged in accordance with charging control,
priority is transferred to the next storage tank or the swimming pool for the period of
time set (e.g. too great temperature differential between collector and storage tank).
As soon as the preferred storage tank (according to setting "Charging priority storage
tank") is again ready to be charged, the transfer of priority will immediately be stopped.
If the parameter is off (---), setting Charging tank priority is used as a rule.
During the period of time set, the transfer of priority will be delayed. This prevents
relative priority from intervening too frequently.
If solar output is sufficient and solar charging pumps are used, parallel operation is
possible. In that case, the storage tank of the priority model can be the next to be
simultaneously charged, in addition to the storage tank to be charged next. Parallel
operation can be delayed by introducing a waiting time. This way, in the case of parallel
operation, switching on of the storage tanks can be effected in steps.
Setting (---) switches off parallel operation.
To remove any existing cold water in the primary circuit, operation of external heat

the upper section is completed.
As soon as the temperature acquired by the temperature sensor (B4/B42) reaches the
setpoint of partial charging, the diverting valve change over to “through-port” and the
rest of the storage tank is charged also.

The DHW request to the boiler is made up of the current DHW setpoint plus the
adjustable charging increase.
Heat transfer makes it possible to transport energy from the buffer storage tank to the
DHW storage tank. In that case, the actual buffer storage tank temperature must be
higher than the actual temperature of the DHW storage tank.
The temperature differential can be set here.
The storage tank can be charged using up to 2 sensors.
It is also possible to combine partial charging with 1 sensor and the legionella function
with 2 sensors (setting 3).

For recooling the DHW storage tank, there are 2 functions available:
• Heating energy can be drawn off either by space heating or the DHW storage tank.
This can be selected separately for each heating circuit (operating page heating
circuit 1…).
• If the collector is cold, the energy can be emitted to the environment via the
collector’s surfaces.

The electric immersion heater is only used if the boiler delivers a fault status message
or has been shut down via boiler lock. This means that in normal situations the DHW is
always heated by the boiler.
Summer
The electric immersion heater is used as soon as all connected heating circuits have
switched to summer operation. The DHW is again heated by the boiler as soon as at
least one of the heating circuits has switched back to heating operation. But the electric
immersion heater is also used if the boiler delivers a fault status message or has been
shut down via boiler lock.
Always
DHW is heated with the electric immersion heater throughout the year. This means that
when using this application, the boiler is never required for DHW heating.
24 h/day
The electric immersion heater is always released, independent of time programs.

If a buffer storage tank is used, it is to be entered here whether the DHW storage tank
receives its heat from the buffer storage tank or directly from the boiler.
When using alternative heat sources, the buffer storage tank temperature is used as a
control criterion for the release of additional heat sources.
It is to be set whether the DHW storage tank receives its heat via the primary controller
or with the help of the system pump (depending on the type of plant).
It is to be set whether the DHW storage tank receives its heat from the solar collectors.

The collector calculates the switching points including the switching differential from the
DHW setpoint and the acquired DHW storage tank temperature.
Thermostat
The DHW temperature is controlled based on the switching state of a thermostat
connected to B3.
When using a DHW thermostat, Reduced mode is not possible. This means that when
Reduced mode is active, DHW heating with the thermostat is locked.
• The adjustment of the nominal DHW temperature setpoint must be equal to or higher
than the setpoint adjustment on the thermostat (thermostat calibrated at switch-off
point)
• The flow temperature setpoint for DHW must be set to a minimum of 10 °C (has an
impact on the charging time).
• In that case, the DHW is not protected against frost.
