Important notes
Thermostats are precision instruments, set and adjusted in factory. Do not open the
device or reset the varnished adjustment screw. This would alter the switching
points, and resetting in the factory would then be necessary.

Important safety information
Please read this before installing and commissioning!
Installation and commissioning
XThermostats may only be installed by
personnel trained in this application
area in accordance with installation
instructions and local legal require-
ments.
XThermostats always should be
installed by using suitable thermo-
wells (TAM and TX). Never dip the
sensor without pocket direct into the
medium. Before selection of a
thermowell, it is necessary to check
for material compatibility with
measured medium.
XCaution when touching the device –
risk of burns. Device can reach on
sensor side a temperature of up to
130 °C. Risk of freezing when work
with medium temperatures below
0 °C.
XIn any case, do not open wiring-box
or plug and do not remove terminal
screws before the device is de-
energized.
XThe device must be used only within
the electrical and thermal limits
specified in the data sheet.

Important safety information
MU2B-0375GE51 R0211A 33
XInductive loads can cause contact
burns or fuse the contacts. The
customer must implement preventive
measures, e.g., through the use of
suitable RC elements.
XDevices must be protected from solar
radiation and rain!
XPrevent vibrations from reaching the
thermostat, e.g., with mechanical
isolation or other vibration damping
measures.
XNever use thermostats as a climbing
aid.
XAvoid condensation water when
operating the device below 0 °C!
XHoneywell GmbH accepts no liability
for non-compliance.

1.2 Mounting and installation
Wall installation
With wall bracket H1 (included as
standard with room thermostats type
TRM). For wall installation of TX and
TAM, H1 bracket needs to be ordered
separately. This is valid for all versions
with housing 2…, 3…, 5…, and 7… (Ex).

XFasten holding bracket (1) horizontal-
ly on wall by means of screws and
plugs (6 mm diameter)
XFasten terminal plate (3) by means of
2 screws M4 on the reverse side of
the switching unit (do not tighten –
maintain approx. 2 mm distance
between casing and terminal plate).
XHang casing on the bracket and
clamp it with two screws M4.
The thermostats can also be fixed directly
by means of 2 screws (4 mm diameter)
on a flat surface (without wall bracket
H1).

Fig. 2. Fixing the sensor cartridge
XFix clamping bracket (1) by means of
2 screws on the wall.
XPress together the angles and insert
the sensor cartridge. After releasing,
the sensor cartridge fits tightly.
Sensor mounting in containers and
pipes
For pressure-tight installation thermowells
in 3 different lengths are available.
For further accessories, see technical
data sheets.
