Technical description
• Temperature range: 35-65°C,
TA-Therm HT 45-80°C. Factory pre-set
at 55°C, TA-Therm with measuring
point at 52°C.
• Nominal pressure: PN 16
• Max. working temperature: 90°C
• Max. differential pressure across
valve disc at closure: 10 bar
• Kv at ΔT2K: DN 15: 0.30,
DN 20: 0.40
Installation (Diagram B)
Fit TA-Therm/TA-Therm HT in each
circulation riser, either at the top or
bottom of the riser. Make sure that the
valve is fi tted the right way round (an
arrow on the valve body indicates the
direction of fl ow) and not closer than
0.5 m from the return pipe.
Temperature setting (Diagram A)
• Slacken the locking screw with the
2.5 mm Allen key, and unscrew it
until it projects slightly above the
handwheel.
• Turn the handwheel anticlockwise to
stop.
• Set the required temperature against
the casting line along the centre of
the valve body (see the dotted line).
• Tighten the locking screw.
Shut-off (Diagram A)
• Slacken the locking screw with the
2.5 mm Allen key, and unscrew it
until it projects slightly above the
handwheel.
• Turn the handwheel clockwise to
stop.
Resetting the temperature (Diagram A)
• Turn the handwheel anticlockwise to
stop.
• Set the required temperature against
the casting line along the centre of
the valve body (see the dotted line).
• Tighten the locking screw.
