Please note: A weather-compensated control unit is equipped with soft boiler start, which prevents condensate being formed

Sizing shunt pump
The flow rate of shunt pump V is calculated according to the following formula:
V=
V
QN x 3600
cp x ∆t x ρW
in m3/h
= Shunt pump volume flow in m³/h
QN = Rated boiler output in kW
cp
= Specific energy 4.2 kWs/kgK
ρ W = Specific weight of water 1000 kg/m³
∆t
= Temperature differential between the flow temperature and bypass
temperature (recommended design temperature differential 30k)
The shunt pump head results from the boiler pressure loss at the selected volume
flow, the pipework pressure loss as well as all individual boiler circuit pressure
losses.
System example
A return temperature limit stat T switches the shunt pump ON, when the permissible
return temperature is no longer maintained.
A return temperature limit stat T1 switches the shunt pump ON, when the minimum
return temperature is no longer maintained.
If the return temperature falls further, the return temperature limit stat T2 signals to
the control unit R, which throttles the heat transfer via one or several mixers M in the
heating circuit.
A return temperature limit stat T regulates a distribution valve M, so that if the
permissible return temperature is no longer maintained, the heating circuit flow will
be partially or fully closed.
After the boiler has been heated up, the distribution valve M will open as wide as the
permissible return temperature requires.
The distribution valve M, can also be installed as mixer into the return.

be able to be shut off. A valve which has been protected against unauthorised closure,
e.g. a cap valve, would also be acceptable.
The system diagram only indicates the safety requirements but is not a recommendation
for specific types of heating network control.

Safety valve
Every boiler must be protected against exceeding the permissible operating pressure
by a diaphragm safety valve or other spring-biased safety valves. Safety valves must
comply with TRD 721. A maximum of three safety valves may be applied to each heat
generator. A flash trap must be installed immediately next to each safety valve for
boilers with a rated output in excess of 350 kW. The installation of flash traps is not
required for hot water heating systems, if each heat generator is equipped with one
or an additional STB and one or an additional pressure switch.

Expansion vessels
The water and gas chamber of pressure expansion valves must be calculated in
accordance with DIN 4807 part 2.
If the permissible operating pressure is lower than the highest working pressure of
the pressure dwell valve, protect the expansion vessel by suitable type-tested safety
valves against excessive pressures. Size open expansion vessels for a minimum
pressure of 2 bar.
Arrange all expansion vessels with shut-off facilities towards the heating system.
Ensure that the shut-off equipment is sufficiently protected against unintentional
closure (e.g. cap valve protected with a wire and seal).
Low water indicator
Equip each boiler with a type-tested low-water indicator. A low-water indicator is not
required for boilers up to 350 kW, since excessive heating at low water conditions is
prevented. This was verified as part of the type testing of the STB installed in the control
unit.
13
Safety equipment
Thermometer
Install a temperature indicator and a facility for checking the flow temperature into the
boiler flow line, so that the actual heating water flow temperature can be recorded. The
permissible flow temperature must be permanently marked on the display scale.
Pressure gauge
The boiler must be equipped with a pressure gauge with immediate connection to
the water chamber or in immediate proximity of the flow, as well as a suitable
connection for the pressure testing device according to DIN 16263 or DIN 16271. The
response pressure of the boiler safety valve and the minimum system pressure must
be permanently marked on the display scale.
Equip every boiler, which is protected above 3 bar or which has a rated output higher
than 350 kW, with a maximum pressure switch (type-tested according to VdTÜV Code
of Practice Issue 100/l).
External pressure monitoring
Monitor the operating pressure of hot water heat generator systems with a minimum
pressure switch, type-tested in accordance with the VdTÜV Code of Practice Issue
100/I, in order to prevent water evaporating inside the heating system as a result of
insufficient external pressure.
Please note:
Install a check valve downstream of the boiler circuit pump to prevent incorrect
circulation.
The pipework between the boiler, the safety valve and the low-water indicator must
not be able to be shut off.
The system diagram only indicate the safety requirements, but is not a recommendation
for specific types of heating network control.
