Installation and
Operating Instructions
Uponor Comfort E Thermostat
dial Set T-85 230 V
Caution !
The device may only be opened and installed
according to the circuit diagram on the device or
these instructions by a qualified electrician. The
existing safety regulations must be observed.
Appropriate installation measures must be taken
to achieve the requirements of protection class II.
This independently mountable electronic device
is de­signed for controlling the temperature in
dry and enclosed rooms only under normal con­
ditions. The device confirms to EN 60730, it works
according operating principle 1C.
1. Application
• Electric Floor Heating Systems
• Hot Water Floor Heating Systems
2. Operation
The controller recognizes the temperature via the
external remote sensor. The controller switches on
when sensor temperature is below set temperature
and it switches off as soon as required room tempera­
ture (set value) will be reached and rise.
The setting range 1 ... 4 corresponds to temperature
10 ... 40 °C.
The controller can be switched ON and OFF by means
of the rocker switch.
Adjustable heating interrupt according standard EN
50559 (Interrupts heating after continous heating of
1hr for 5 Minutes).
2.1 Function of the lamps
Function Lamp red
Heating is on on
Floor sensor fault flashes
2.2 Fault of the floor sensor
If a sensor fault (short­circuit or break) occurs, the
controller will switch to fault mode. The heating will
function with max. 30 % of the energy (operation for
30 % of the time). This provides frost­ and overheat
protection.
3. Installation

a) Controller
– System to be wired free of voltage
– Pull off the adjusting knob
– Loosen the fixing screw
– Remove the cover
– Connection acc. to wiring diagram (inside cover)
b) Remote Sensor
Attention:
For more easy replacement sensor cable should
be put into a protection tube. The
can be lengthened up to 50 m by using a standard
2­core cable for mains voltage and with a cross
section of 1,5 mm2. Close parallel routing along
high voltage cables or in cable ducts should be
avoided or otherwise a screened cable has to be
installed.
Attention:
In case of failure the sensor cable still can carry mains
voltage.
