installation and operation manual
The terneo s thermostat is designed to maintain a constant temperature from 5 to 40 °C in underfloor heating systems based on:
- Electric heating cable or film
- Water floor using a normally closed electrothermal servo with an operating voltage of 230V.
According to the data from the temperature sensor, The thermostat located in the floor controls the heating: turns off the heating when the desired temperature is reached and turns it on when it drops by 1 °C.

RELIABILITY OF THE POWER RELAY
provides protection against frequent switching. If there was less than 1
minute between relay switching, relay activation will be delayed. Protection
operation will be indicated by a flashing dot. All settings are stored in NON-
VOLATILE MEMORY.
DURABILITY AND RELIABILITY OF POWER RELAY
CONTACTS is carried out by switching the load as close as possible to the
moment when the voltage sinusoid passes through zero. Small deviations from
the zero crossing are possible, associated with different trip times for
different types of power relay.
CONNECTION SCHEME
Thermo supports two types of sensors: analog sensor (factory setting) or
digital sensor (D18).
Temperature sensor is connected to terminals 1 and 2.
To connect a digital sensor:
- connect blue wire to terminal 1, white wire to terminal 2;
- in the functional menu of the thermostat, select the type of sensor: d18 (see table 1, menu item Sensor type « »).
Power voltage (230 V ± 10 %, 50 Hz) is supplied to terminals 4 (N neutral and
5 (L phase) Load (connecting wires from heating element) is connected to
terminals 3 and 6.
THE STAT IS MOUNTED AND CONNECTED after the installation and load testing
AFTER INSTALLATION MAKE SURE THAT EXTERNAL SENSOR AND MAINS VOLTAGE ARE
CONNECTED CORRECTLY. In the case of incorrect wiring, is possible failure of
the thermoregulator.
Wiring 1. Connection of the circuit breaker and SSD.
INSTALLATION
The thermo is designed for indoor installation. When installed in a bathroom,
toilet, kitchen, swimming pool the thermo should be installed at the place out
of reach of casual spraying.
The ambient temperature during installation must be between –5 … + 45 °C. The
installation height of the thermo should be in the range 0.4…1.7 m above the
floor level.
To protect against short-circuit in the load circuit the circuit breaker (CB)
has to be installed before installing the thermo . The circuit breaker is
installed in the gap of phase conductor, as shown in the Wiring . It should be
designed for not more than 16 A. To protect a people against electric shock
leakage is installed the SSD (safety shutdown device).
This event is obligatory when installing floor heating in wet areas. For
working of SS the heating cable screen must be grounded (connected to the
protective conductor PE) or, if there is twowire network, it is necessary to
make protective neutral earthing. That is to connect the screen to a zero
before SSD .
The thermostat is mounted in the standard mounting box 60 mm in diameter, with
mounting screws. For installation you must:
- make a hole in the wall for box mounting and wall chase for power wires and the sensor;
- take the power wires of the heating system and the sensor to the mounting box;
- perform the compounds according to the passport data;
- fix the thermostat in the mounting box.
The thermostat terminals are designed for a wire with section not more than
2,5 mm’. To reduce the mechanical loads on the terminals it is desirable to
use a soft wire. The wires are tightened in the terminals using a screwdriver
with a blade width no more than 3 mm. The screwdriver with a blade width more
than 3 mm can cause mechanical damage to the terminals. This may result in the
loss of right for warranty. The terminals should be tighten with torque 0,5
N-m.
If necessary is acceptable reduction and increasing (up to 20 m) of sensor
connecting wires. To increase the length is unacceptable to use two conductors
of a multiwire cable that is used to power the heater.

REPLACE IT.

EXPLOITATION
Use the «≡»button to navigate through the menu (table 1) Use the «+» and «–»
buttons to change the parameters. After pressing the button for the first time
the parameter will flash, after pressing it for the second time the parameter
will change. In 5 sec after the button was pressed the indicator will return
to displaying the temperature. When the buttons aren`t currently being used
the brightness of the indicator and the screen will be reduced to 30%.
Temperature selection
(factory setting 25 °С)
Use «+» and «–» to select the temperature. About the supply of load to the
warm floor is signaled by the glow of the red indicator. In the event of a
sensor failure, the thermostat will continue to operate in percentage control
mode (see page 6).
Hibernation
Hold the «≡» button for 4 sec (3 dashes will appear on the display one by one)
before appearing on the screen «oFF». To switch off thermo completely you
should switch off the circuit breaker.
To exit, also hold «≡» for 4 seconds until«on» appears on the screen.
Button blocking
(child and public protection)
Press the «+»and «–»buttons at the same time for 6 sec till the «Loc» («oFF»)
sign appears on the screen.
Resetting to the factory settings
Hold any 3 buttons till the «dEF» sign appears on the screen. After releasing
the buttons the thermostat will restart and reset the settings to the factory
settings.
Firmware version
Hold «–» button for 6 seconds. The manufacturer reserves the right to make
changes to the firmware in order to improve the characteristics of the
thermostat.
POSSIBLE PROBLEMS, CAUSES AND WAYS TO OVERCOME THEM
The load does not operate according to the settings, every 5 seconds the screen displays or «OC» «SC»
open circut — open of circuit of the sensor
short circut — short circuit of the sensor
The temperature controller has switched to the Emergency Timer Mode.
Possible reason: failed connection, damage to the sensor circuit temperature
exceeds the limits of the measured temperatures (Technical data table).
Required: check the junction of the temperature sensor with the thermostat and
its circuit, check for mechanical damages along the entire length of the
connecting wire and no power wiring that passes close.
Operation in the Emergency Timer Mode: the mode will ensure the operation of
the underfloor heating in case of damage to the sensor: t he user selects the
time of the work of the applied force, the rest time in the 30 – minutes
cyclic interval the applied force will be switched off. The time percentage
can be changed with the «+» and «–» buttons in the range of 10 … 90%.
At the first switching on, this value is 50% «50P», while the load in the
30-minute time interval will be turned off for 15 minutes.
Heating temperature control is not available in this mode.
The load is disabled, «oht» flashes on the screen
Тemperature inside the frame exceeds 85 °С, triggered protection against internal overheating
Possible reason: inner overheating of the device to which can lead: bad
contact in the terminals of the device, high ambient temperature, overwhelming
power output or incorrectly selected cross-section of wires for connecting.
Required: check tension of power wires in the device terminals, make sure that
the switching load does not exceed the permissible and that the cross section
of the wires is selected correctly.
Feature of protection against internal overheating: the device will be
unlocked in case if the temperature inside will decrease to 08 °C. If the
protection trips more than 5 times, the device is blocked until the
temperature inside the case drops to 80°C and one of the buttons is pressed.
Every 5 sec the screen displays «Ert»
Reason: open or short circuit of the internal overheating sensor. Control over
inner overheating will not be done.
Required: Otherwise, control over inner overheating will not be done. Send the
device to the Service Center.
The load is disabled, indicator nor the screen light up
Possible reason: no power supply voltage.
Required: check availability of power supply voltage. If power supply voltage
is available then contact the Service.
When the screen turns on it displays 5 seconds «Er0»
Reason: malfunction of the control system for the transition of the sinusoid
through zero.
Required: Send the device to the Service Center.
Otherwise, the control of the transition of the sinusoid through zero will not
be carried out.
