4.2. MIRU Control and
TBLZ-1-23-aa pressure sensor
If
pressure regulation is used,
install the pressure sensor
on or near the MIRUVENT fan’s extract air duct. See illus-
tration. Set the pressure sensor function selector switch to
position 1. See illustration.
If
flow regulation is used,
install the pressure sensor at
a suitable location in the compartment for the fan motor
inside the MIRUVENT fan. Connect tubes to the existing
measurement tappings in the same space. Connect the
tube from the blue tapping to pressure port (-) and con-
nect the tube from the white tapping to pressure port (+)
on the pressure sensor. Set the pressure sensor function
selector switch to position 0. See illustration.
Connect the modular cable to an optional modular con-
nection in the pressure sensor. See the illustration.
If the pressure sensor for pressure regulation
and
for flow
measurement is used, they must be connected in series.
Connect modular cable(s) to MIRU Control in modular
connection X10 and/or X11. See illustration.
