DESCRIPTION
PT713-EI is a digital thermostat with a room and floor sensor, specially designed for electric floor heating
control. The internal-external sensor combination provides for the regulation (for setting, see page 8)
of:
1) room temperature (internal sensor) - when comfortable room temperature is required;
(external sensor) - when comfortable room temperature is required; locate the external
sensor in a suitable place where the measured values will not be
distorted;
2) floor temperature (external sensor) - suitable, for instance, for bathrooms where a warm floor is
desirable, irrespective of the room temperature;
3) combined (both sensors)
- the internal sensor scans the room temperature, and the external
one monitors the maximum floor temperature; comfortable room
temperature is required, however, with simultaneous monitoring of
the floor temperature (suitable for wooden and laminated floors).
Another advantage is the simple installation in KU/KP68 junction boxes by means of the PLUG-IN system; the possibility of setting 9 weekly programs with 6 temperature changes per day; regulation type
selection (page 6); as well as other functions for efficient regulation of the floor heating.
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 flows, 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 (type CT04-10k P, CYXY 2 x 0.5 mm, 10 kΩ, length 3 m, PVC plastic case)
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 must only be executed by a properly qualified person!
Switch off 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 page 3 and 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 10).

BACKUP BATTERY (rechargeable NiMH):
The thermostat is equipped with a backup battery. The battery charging time is about 12
hours. In case of voltage failure, the device automatically operates on the backup battery (the
relay is in the off state). Actual time is kept for more than 100 hours; the preset programs are
kept permanently in the E-EPROM memory. When the voltage is restored, the thermostat returns to the last selected mode.
After the first connection of the thermostat, the backup battery is charged for about 12 hours!
PLUG-IN SYSTEM = quick and easy installation. The thermostat is divided into the power
part and the main microprocessor part, which can be joined by simple insertion of the interconnecting terminals. The input conductors (or external sensor) are connected to the power
part terminals and fastened to the junction box; then you can simply finish the installation by
inserting the main part onto the power part.

8 EXTERNAL SENSOR SELECTION
Select the external sensor according to the regulation type:
1, Regulation by room temperature - the sensor is located in the room (selection - - -)
2, Regulation by floor temperature - the sensor is located in the floor (selection - - -)
3, Monitoring of floor maximum temperature - the sensor is located in the floor (selection 15 to 99.5°C)
Choose according to the type of use with the
/
buttons and press
MENU
to confirm.
EXTERNAL SENSOR USED AS ROOM ONE:
---
The external sensor, if connected, measures the
temperature at the point of location (suitable, for
instance, for bathrooms, 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.
EXTERNAL SENSOR USED AS FLOOR ONE (MAXIMUM FLOOR TEMPERATURE IS SET):
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.
After connecting the external sensor, it is NECESSARY to RESET (see parameter 11)!
9 MINIMUM TEMPERATURE OF FLOOR HEATING
This setting can be used only if the external sensor is connected and the “External sensor used as
floor one” function is selected. It determines the time interval during which the minimum floor temperature should be maintained. Thus, it is possible to maintain a comfortable floor temperature during
the preset time. If the temperature drops below the given limit, the floor is automatically heated up to
the minimum temperature.

Note: The example shows a setting where the floor temperature
must not drop below 10 °C all day long.
10 CURRENT TEMPERATURE CORRECTION (internal sensor)
This is used for correcting the thermostat-measured temperature. The
setting can be done only after 12 operating hours, when the internal
sensor temperature has settled. Measure the room temperature with
a thermometer; if it is different from that measured by the thermostat,
set the correction within the range from -5 °C to +5 °C.
Set the pertinent value with the
/
buttons and press MENU
to confirm.
11 FIRMWARE VERSION / DEFAULT SETTING RECOVERY
Information on the firmware version. If you keep pressing the
button (approx. 3 sec), the RESET message briefly appears on the LCD, and the thermostat recovers the default setting!
You can exit the CONST mode at any time by simultaneously pressing the MENU and
buttons (return to the basic mode).
