1. THERMOSTAT USE INSTRUCTION
The programmable thermostat C 511T is specially developed to
provide comfort heating using as little energy as possible. C 511T
is used to control the floor heating but can equally be used with all
types of heating systems.
The thermostat C 511T can switch your heating system on at
pre-determined time on different days of the week. For each day
of the week you can set individual temperatures for 4 different
periods, called events. Lowering the temperature when the home
is unoccupied will reduce your energy costs without reducing
comfort.
The thermostat C 511T comes with a default factory schedule
3

4
suitable for most installations. The thermostat operates in
compliance with this default programme unless you set your
own weekly schedule. The thermostat has a reset button marked
R allowing you to reset the thermostat back to default factory
settings.
The thermostat C 511T features an adaptive function that
automatically changes the start time of heating periods so as to
ensure that the required temperature is reached at the set time.
After 3 days the adaptive function will have calculated when the
heating must be switched on.
2. FLOOR TEMPERATURE SENSOR INSTALLATION
Floor temperature sensor NTC is in protection class IP67 and
complies with applied standards EN 61386-1.
The temperature sensor is mounted in the oor as shown in Pic. 1.
The resistance of the oor temperature sensor is shown in Pic. 2.
Cut a groove in the oor and the wall to the thermostat junction
box. Put the sensor pipe into the groove and seal its end with
aluminium foil or a special metal cap to avoid the concrete
entering the pipe. Bend the pipe (10-16mm) between the wall and
the oor with a large bending radius (8 diameters). The end of the

5
pipe should be placed between the cable loops (under the heating
mat) but not closer than 30cm from the edge of heating area.
Insert the sensor into the pipe. This allows the sensor to be easily
replaced if necessary. The sensor cable can be extended by up to
50m by means of a separate cable. Connect the oor temperature
sensor to the thermostat as shown in the wiring diagram (Pic 4).

3. THERMOSTAT INSTALLATION
• Slide the power button down to OFF “0”.
• Release the front cover ONLY by inserting a small
screwdriver into the hole on either side of the thermostat
(Pic. 3). DO NOT open the thermostat by releasing the four
xing clips on the back.
• Make electrical connections according to the diagram (Pic.

• Mount the thermostat in the wall socket. Fit the frame and
carefully press the cover onto the thermostat. Ensure that
both the power slide button on the cover and the power
