Mounting ❸
QT should be mounted on the AB-QM by
hand. Maximum allowed torque is 5 Nm.
Sensor installation ➍
AB-QM is to be installed after the last
radiator in the riser of one-pipe radiator
system.
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 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 thermostat is set to the desired setting
by hand. When minimum or maximum
setting is required, QT setting knob is to
be moved slightly in opposite direction
to ensure optimal performance of the
thermostat.
