Room Temperature Controller
UTE 4800 (with change over contact)
1 Principle of operation
The programmable room temperature controller UTE 4800
allows programming switching events (up to 9) and temper-
atures according to personal needs. After installation the device
automatically shows the time of day and the room tempera-
ture. In AUTO mode, the Heater (Cooler) will be automatically
activated according to programmed time and temperature.
Program 1 is the default pre-set program (see 8.). The room
temperature will be controlled according to the temperature
measured by the internal or remote sensor. The Heater will be
switched on when the temperature drops below the current
set-point.
2 Installation
Caution!
This device must be installed by a qualified electrician,
according to the wiring diagram on the device and in com-
pliance with all applicable safety regulations.
Appropriate installation measures must be taken to achieve
the requirements of protection class II.
This device, is used to control the temperature only in dry
rooms, under normal environmental conditions. This elec-
tronic device conforms to EN 60730, It is an “independently
mounted control” and works according to operating prin-
ciple 1C.
3 Use
The electronic Room Temperature Controller UTE 4800 can be
used to control the room temperature in conjunction with:
• Thermal actuators for e.g. water based floor heating or
convector heaters
• Oil or Gas heaters
• Circulation pumps
• Heatpumps
• Underfloor heating with heat / cool change over
4 Features
• One line text display for simplified operation
• Back light
• Real time clock (setting of year, month, day, time)
• Automatic Summer- Winter time change over
• Max 9 events per day (each day independently)
• Pre-set and adjustable programs
• Optimum-Start
• Arm chair programming (with display unit removed)
• Holiday-Mode (date from – until can be set)
• Timer (Party) specific temperature for configurable duration
• Relay change over contact (for uses in conjuction with
connection strip EV 230 H/K...)
• Range limits for adjusting max and min temperature
• Access protection
• Operating language can be selected
• Control mode PWM or ON/OFF
• Minimum output on/off time and hysteresis configurable for
ON/OFF control
• Valve protection
• Adaptation to valves normally open or normally closed
• Measures the room temperature with the internal sensor or a
remote sensor
• Adjustable heating interrupt according standard EN 50559 (not
for valves normally open)

8. Pre-set programs
There are 3 pre-set time/temperature programs in the controller.
Pre-set program 1 (as shown below) is the default. Therefore, if
pre-set program 1 is the best program to suit the application,
there will be no need to change the time/temperature settings
on the device.
To select another program see 9. G1.

Electric connection
Caution: disconnect electric circuit from supply
Connecting according to Wiring Diagram
For flexible or solid wires 1 – 2,5mm

Connecting the remote sensor
F 193 720 or F190 021 (optional)
In order to measure the room temperature, instead of the inter-
nal sensor an external one can be used.
Remote or internal sensor selection can be made via menu
item H1.
Lay sensor inside a protective tube (simplifies replacement). The
sensor lead can be extended up to 50 m by using a cable and
connections suitable for 230 V. Avoid laying sensor cable along-
side power cables, for example inside a conduit.
Caution!
The sensor is at mains voltage.
