Thermostatic heating limiter
• Through the thermostatic heating limiter
40
in the heating circuit
the return temperature of the primary heating return is limited.
• Temperature sensor
36
is placed at heating-return-primary
side. This placement is recommended for radiator heating (then
the thermostatic head
40
has to be set +5°C above desired
temperature).
Please move the temperature sensor
36
to heating-supply-

Thermostatic temperature retention module
(TTV)
• A TTV
12
is inserted in the Apartment units or at the last unit in
DOLQHDQGHQVXUHVWKDWWKHULVHUVRUVXSSO\OLQHVGRQRWFRRORႇ
during the periods when heating is not required and during longer
tapping breaks. At up to 5 residential unit over each other a TTV
is required at the end. At more than 6 units the number has to be
agreed. All residential units that are more than 5 meters from the
line, should be equipped with a TTV. If a circulation is mounted, a
TTV is not required (TTV is included in the scope of delivery).
• The thermostatic temperature retention module serves to maintain
the heat in the supply line.
• The valve disposes of a setting scale. The setting range is
printed on the cap. Temperature measuring is carried with a
directly immersed sensor insert in the valve body. The setting is
performed steplessly.
• “Comfort Setting TTV” (faster achieving of the DHW tapping
temperature, however higher supply losses)
approx. 10-12°C (below the primary supply temperature)
Example: primary supply 70°C, TTV setting at approx. 60-58°C
• “Standard Setting TTV” (marginally longer waiting time until the
DHW tapping temperature is achieved, smaller supply losses)
approx. 15°C (below the pirmary supply temperature)
Example: primary supply 70°C, TTV setting at approx 55°C
