DESCRIPTION
PT712-EI is a digital thermostat with a room and floor sensor, specially designed for electric
floor heating control. The internal-external sensor combination enables the regulation of:
1) floor temperature (external sensor) - suitable, for instance, for bathrooms where a warm floor is
desirable, irrespective of the room temperature;
2) room temperature (internal sensor) - when comfortable room temperature is required;
3) combined (both sensors)
- the internal sensor scans the room temperature, while the
external one monitors the maximum floor temperature;
comfortable room temperature is required, however, with
simultaneous monitoring of the floor temperat
(suitable for wooden and laminated floors).
Another advantage is simple installation in the KU/KP68 junction boxes by means of the PLUG-IN
system, as well as the possibility of setting 2 weekly programs with 6 temperature changes per day.
INSTALLATION AND LOCATION
Install the thermostat in a suitable place (minimum height of 1.2-1.5 m above the floor) where its operation
will not be affected by direct hot/cold air flow, sunshine or other disturbing influences. Do not mount the
thermostat on an exterior wall either. In rooms with increased humidity (bathroom, kitchen), observe valid
standards and install the thermostat as far from the bathtub, shower, basin or sink as possible.
The external floor sensor must be located in a flexible plastic tube embedded in the floor, as near to the
surface as possible. The tube must be sealed and protected against in-leak of building materials so that
the floor sensor can be replaced easily, if need be. It must not run parallel with power conductors! It can
be extended to a maximum length of 30 metres. The installation can only be done by a properly qualified
person! Disconnect power supply before installation!
1) Switch off the main circuit breaker.
2) Check that the junction box is placed parallel with the wall.
3) Separate the power part of the thermostat from its microprocessor (main) part; see Fig. 1.
4) Pull the connecting terminals out of the thermostat rear part, see Fig. 2.
5) Connect conductors to the terminals acc. to the wiring diagram below, see Fig. 3.
6) Insert the terminals into the thermostat terminals and fasten the power part to the junction
box, see Fig. 4 and 5.
7) Insert the main part connector into the power part and push it; the metal springs must
fit in the given holes, see Fig. 6 and 7.
8) Switch on the main circuit breaker; the thermostat is ready for operation.
Note: We recommend you test correct connection after installation, see the TEST function (page 7).

where you wish to have a warm floor irrespective of the
room temperature);
This use of the sensor is indicated by the
sign on the LCD.
15…99,5°C The external sensor, if connected, monitors the floor
temperature; the maximum permissible temperature is set
for the floor heating (you regulate with the room
temperature, monitoring the floor temperature
at the same time).
The floor (monitoring) sensor is indicated by the
sign on the LCD.
If the preset limit temperature is exceeded, the thermostat is switched off irrespective of
the room temperature, and the STOP message appears on the LCD. Once the external
sensor temperature drops by 0.5 °C, the heating device is switched on again.
If the sensor is not connected or it is defective, the C2.Err error message appears on the
LCD.
