1. Area of use
The UTE 2100 and UTE 2500 electronic tempera-
ture controllers can be used to control the floor
and room temperature.
2. Installation site
• The controller should be mounted in a place
in the room that is easy to access for operation.
• Mounting height: approx. 1.5 m above the
floor.
• Preference should be given to installation
on an internal wall. Avoid external walls and
draughts from windows and doors.
• Ensure that the room’s normal convection air
reaches the controller freely without restric-
tion. The controller should therefore not be
mounted inside shelf units or behind curtains
and similar coverings.
• Extraneous heat has a negative influence on
the control accuracy.
• Direct sunshine, proximity to televisions, radios
and heaters, lamps, stoves and heating pipes
must be avoided.
• Install in flush-mounting box 60mm
3. Electrical connection
Important!
Disconnect the electric circuit from the
mains
Connection in the following steps:
• Pull off the temperature control knob
• Undo the fastening screw
• Remove the top part of the housing
• Connect as shown on the circuit diagram (see
bottom of housing or circuit diagram in these
instructions.)
• Install in the reverse order
Important!
Mount in non-conductive (plastic)
flush-mounting boxes only.

Jumper:
The jumpers (links) can be used to set whether
the controller operates “normally closed” (NC) or
“normally open” (NO) actuators. Depending on
the setting, the output signal is as follows:
NC: 230 V / 24 V  Heat/Cool On
0 V  Heat/Cool Off
NO: 230 V / 24 V  Heat/Cool Off
0 V  Heat/Cool On

Important!
The device may only be opened by an electrically
skilled person and must be installed as shown on
the circuit diagram on the device and in these in-
structions. The existing safety regulations must be
followed.
The relevant installation measures must be taken
to achieve the requirements of protection class II.
This independently mountable electronic device
is used to control the temperature in dry and en-
closed rooms only, with normal environment. This
device conforms to EN 60730, it operates accord-
ing to type 1C action.

7. Restricting the temperature setting
range:
The temperature controller is set in the factory
to the maximum setting range of 5 … 30 °C
(see Figure 1).
There are 2 adjusting rings in the control knob.
These can be used to set the temperature set-
ting range as required.

Restricting the temperature setting range
* in cooling mode the setpoint temperature is increased by 3.5 °C.
