Installation of a DHW tank temperature sensor or aquastat
1.
Carefully pull sensor mounting
hardware out from tank sensor well.
2.
Mount sensor on the outside of the
sensor spring-clip (not in the center
groove) so that it is flush with the
front of the sensor spring-clip.
3.
Push sensor cabling into groove of
mounting hardware.
4.
Carefully tighten plastic screw to
secure sensor cabling in place.
5.
Install sensor well and reducing
coupling (included in Connection
Fitting Package). Use approved pipe
sealant.
6.
Mount insulation on sensor well.
Where
Vitotronic 200
or
300
is utilized
to control DHW production (for
Vitotronic 100, see the following page):
7.
Insert DHW tank temperature sensor
(supplied with Vitotronic 200 or 300)
fully and completely into sensor well.
Due to the length of the stainless steel
well (15” / 380 mm), care must be taken
to ensure that the sensing bulb of the
limit is inserted and pushed to the end of
the stainless steel well.
8.
Carefully tighten screw on sensor
well to secure sensor in place.

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!
