terneo 211201 Smart Control of Heating

The terneo s thermostat is designed to maintain a constant temperature from 5 to 40 °C in underfloor heating systems based on:

1. Electric heating cable or film
2. 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.

READ BY THE END OF THIS DOCUMENT,

• before the installation and operation of the device. This will help to avoid possible danger, mistakes and misunderstandings.

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

The thermostat supports two types of sensors: analog sensor (factory setting) or digital sensor (D18). The 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»).

Load (connecting wires from heating element) is connected to terminals 3 and 6.

THE THERMOSTAT 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 thermoregulatory.

INSTALLATION

The thermostat is designed for indoor installation. When installed in a bathroom, tolet, kitchen, swimming po0l the thermostat 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 thermostat 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 thermostat. The circuit breaker is installed in the gap of phase conductor, as shown in the Wiring 1. 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 installingfloor heating in wet areas. For working of SSD 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.

Mounting of the sensor must be performed SO THAT IT WAS POSSIBLE TO EASILY REPLACE IT.

EXPLOITATION

Use the «=» button to navigate through the menu (table 1). Use the «t» 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 C)

Use «t» 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.

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 thermostat 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 «OC» or «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 or 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: the user selects the time of the work of the applied force, the rest time in the 30-minute cyclic interval the applied force will be switched off. The time percentage can be changed with the «t» 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.

FUNCTION MENU

The load is disabled, «oht» flashes on the screen

The temperature inside the frame exceeds 85 °C, triggering 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 the 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 80 °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: Send the device to the Service Center.
• Otherwise, control over inner overheating will not be done.

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.
