Aquastat installation (when using a Vitotronic 100)
Where a Vitotronic 100 and a
Viessmann Power/Pump Control Module
(accessory) are utilized to control DHW
production, follow these aquastat
mounting instructions:
1. Insert the extended capillary of the
aquastat (supplied with Viessmann
Power/Pump Control Module, not
illustrated) fully and completely into
sensor well. Mount aquastat
inconspicuously on tank paneling.
Follow instructions below with
regard to sensor and spring clip
installation.
... if aquastat is to be mounted remote
from the tank well,
2. Align sensor bulb with spring clip.
3. Slide assembly into well.
4. The retention spring clip must press
the bulb properly to ensure surface
contact with the well.
... if aquastat is to be mounted directly
onthetankwell,
5. Mount aquastat with holding clip
supplied directly onto well. Bend
capillary tube into groove opening to
allow for mounting of aquastat.
To ensure optimum, safe operation,
the supplied stainless steel well must
be installed. The well diameter is
large enough to accommodate a wide
variety of sensing bulbs.
Always use spring clip to ensure
proper contact of capillary bulb
against the stainless steel well for
proper sensing/heat transfer!
WARNING
Grounding connection
1. Connect the grounding in accordance
with the requirements stipulated by
your local electricity supply company
and current local regulations.

WARNING
Domestic hot water temperatures
over 125°F / 52°C can cause severe
burns instantly or death from scalds.
Children, disabled and elderly are at
highest risk of being scalded.
Feel water before bathing or

HAlways install DHW tank batteries
with connected DHW circulation.
1. Pipe together boiler and tank as
illustrated. Connections must be
accessible for service (use factory
supplied adaptors).
2. Insulate domestic hot water supply
piping.
Due to the potentially high DHW
temperatures generated by the solar
heating system, the domestic hot water
temperature must be limited to a
maximum of 140ºF/60ºC by installing a
mixing device, e.g. thermostatic mixing
valve. The mixing device does not
completely eliminate the risk of scalding
at the tap. The installation of a mixing
tap is required.
DANGER IMPORTANT

Domestic Water Connections (continued)
Always ensure the use of type approved devices. Safety devices include the following components:
HIsolation valves
HDrain valve
HPressure reducing valve
where required by local jurisdiction
HDrinking water filter
where required by local jurisdiction
HBackflow preventer
Where backflow preventers are
required, a domestic water expansion
tank installation is required in the cold
water inlet piping before the cold
water enters the tank. The backflow
device must be installed according to
the manufacturer’s installation
instructions. Observe local codes and
regulations.
HTempering valve
A tempering valve must be field
installed where storage tank
(domestic hot water temperature)
exceeds local restricted temperatures
or 140°F / 60°C. Check code
requirements.
In situations where a booster pump is
used to maintain DHW pressure,
Viessmann strongly recommends the
installation of an oversized expansion tank
to ensure longer, less frequent pump
cycles with less severe pressure
gradients. If possible, use flexible piping
before and after booster pump to isolate
system piping from vibration and shocks.
HTemperature and pressure
relief valve
A temperature and pressure relief
valve (T&P valve) is supplied with the
tank. The heating contractor must
install the valve on each tank in a
method meeting code requirements.
If local codes require a different relief
valve, consult Viessmann
Manufacturing for a substitute valve.
The tank is approved for 150 psig.
Maximum operating pressure is 150
psig.
The T&P valve supplied with the tank
is manufactured by Watts Industries
(Model 40XL-8), set to 150 psig for
US and Canadian installations (100
psig for Canadian installations for
120 USG / 450 ltr tank size only). The
valve is ASME pressure steam rated
for 998 MBH and CSA temperature
steam rated for 200 MBH.
It is tested under ANSI Z21.22 Code
for Relief Valves and Automatic Gas
Shut-off Devices for Hot Water
Supply Systems. The relief
temperature is set at 210°F / 99°C.
The valve has a male threaded inlet
and female threaded outlet, both ¾”
sizes.
Proper installation of the T&P valve
shall include all of the following:
- The T&P valve shall be installed in the
pipe connection point marked TPV in
the tank instruction manual.
- The discharge line from the T&P valve
shall be ¾” / 1.9 cm ∅and run to a
safe place of discharge approximately
1 ft / 30 cm above the floor, close to
a floor drain.
- The discharge line must be as short
as possible and pitch downward from
the T&P valve and terminate plain.
-Donot route discharge line to the
outdoors.
-Donot install any type of valve or an
obstruction of any kind between the
tank and the T&P valve, or between
the T&P valve and the discharge line
outlet.
5285 658 v2.1
IMPORTANT
The discharge line for the T&P valve
must be oriented to prevent scalding
of attendants.
WARNING
The valve test lever must be operated
at least once per year by a licensed
professional heating contractor to
ensure that waterways are clear. A
licensed professional heating
contractor shall reinspect the T&P
valveatleastonceeverythreeyears.
Failure to inspect can result in unsafe
temperature or pressure build-up,
which can result in death, serious
injury or substantial product/property
damage.
