Thermostatic actuator QT / QTL
ENGLISH
Assembly
❶
Insert adapter ① into thermostat neck
Design
❷
Mount AB‑QM valve ③ on hot‑water pipe (see
instruction for AB‑QM)
① Setting knob
② Adapter
③ AB‑QM valve
④ Hot‑water pipe
⑤ Temperature sensor
Set desired setting on AB‑QM
(see instruction for AB‑QM)
Mounting
❸
QT/QTL should be mounted on the AB‑QM by
hand. Maximum allowed torque is 5 Nm.
Sensor installation
➍
AB‑QM is to be installed on the return pipe.
In general the sensor must always be placed
warmer than the thermostat head.
In case of one‑pipe system the AB‑QM needs to
be installed after and as close as possible to the
last radiator.
QT should be mounted on the AB‑QM by hand.
Maximum allowed torque is 5 Nm.
For proper heat transfer between a heating
water pipe and the thermostat sensor, it is very
important to apply thermo paste (included in
the box) on the surfaces in contact.
It is recommended to insulate the sensor if
the thermostat is installed in a very cold place
(< 5 °C).
Sensor itself can be mounted in any direction. It
can be mounted above or below sensor head.
Setting
❺
QT/QTL temperature setting depends on AB‑QM
flow setting.
It is necessary to set the AB‑QM to desired
setting before the thermostat is mounted. It is
recommended to set AB‑QM between 30 and
70 % flow setting.
QT/QTL thermostat is set to the desired setting
by hand. When minimum or maximum setting
is required, QT/QTL setting knob is to be moved
slightly in opposite direction to ensure optimal
performance of the thermostat.
Please note that the attached tables are indicative and will
vary depending on the application. They are to be used as a
guidance only. For exact temperature verification tempera‑
ture needs to be measured at reference point and the sensor
setting adjusted accordingly.
