Thermostat terneo b Smart Temperature Controller Instruction Manual

b Smart Temperature Controller
Instruction Manual

Thermostat terneo b is designed for constant temperature maintenance 5…40 °С. Temperature is regulated in the place of temperature gauge location.
The sensor must be positioned in such a way as to allow for its replacement in the future.
This temperature regulator is perfectly suitable for temperature regulating in the system warm water floor by means of electro-thermal servo actuator with operating voltage of 230 V. Servo actuator can be both normally closed, and normally open. At the connection of normally open servo actuator to the temperature regulator use in the functional menu of the temperature regulator function «Inverse load control».

TECHNICAL DATA

IMPORTANT. Before the installation and operation of the device, please read by the end of this document. This will help to avoid possible danger, mistakes and misunderstandings.
WIRING
Analog sensor is connected to terminals 1 and 2. Wires colors are of no importance.
Digital sensor is connected to terminal 1 using white wire and to terminal 2 using blue wire. If the thermo changes stat to the Emergency Timer mode page 7 ( ), try connecting to terminal 2 using blue wire and to terminal 1 using white   wire. If, at both attempts, the thermo does not see stat the sensor, contact the Service Center.
Power voltage (230 V ± 10 %, 50 Hz) is supplied to terminals and , at that phase (L) is determined 34 by indicator and is connected to terminal , and neutral (N) 4 — to terminal .3
The connecting wires are connected to the load terminal 5 and the zero terminal block (not included to the set). DO NOT PERFORM the load connection to the network zero at terminal 3! Wiring 1. Circuit breaker and RCD wiring Wiring 2. Magnetic actuator

INSTALLATION

The thermostat is designed for indoor installation. The ingress risk of moisture or liquid into the place of installation must be minimized. 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. The temperature controller  hould be mounted in a special cabinet, which allows accessible installation and operation. The cabinet must be equipped with a standard 35 mm mounting rail (DIN-rail). The temperature controller has width of three standard 18 mm modules. The thermostat is mounted and connected after the installation and load testing.
In order to protect from short circuits and excess power events appearance in the load circuit, it is necessary to install an automatic circuit breaker (CB), which should  be installed in the live wire break, as shown on Wiring . 1 In order to protect a person from electric shock, a residual current device (RCD) should be installed. The load should be grounded (connected to the protective conductor) for proper operation of the RCD or, if the power supply is twowire, a protective grounding (i.e. load to neutral to  the RCD) should be made. To install the temperature controller you should:

• fix the temperature controller on the mounting rail (DIN);
• supply power, load and sensor wires;
•  make a connection according to this manual.

The terminals of the temperature controller are designed for a wire with a cross section not exceeding 16 mm .
It is desirable to use a soft copper wire to reduce the mechanical loads on the terminals. The use of aluminum is not desirable. Strip the ends of wires 10 ± 0,5 mm. If the stripped end is longer, it may cause a short circuit and, if shorter, can cause an unreliable connection. Use cable lugs. Loosen the terminal screws and insert the stripped end of the wire into the terminal.
Tighten the power terminal with moment of 2,4 N·m and sensor terminal — 0,5 N·m. Poor tightening can lead to poor contact and overheating of terminals and wires, and excessive tightening — to damage of terminals and wires. The wires are tightened in the power terminals with a screwdriver with a bit width of not more than 6 mm, and in the terminals for the sensor — of not more than 3 mm.
A screwdriver with a bit width of more than 6 mm for power terminals (more than 3 mm for sensor terminals) can cause mechanical damage to the terminals. This may cause to the loss of the warranty.
If necessary the sensor connecting wires may be shortened and extended (for not more than 20 m). It is necessary for the temperature controller to switch the current to no more than 2/3 of the maximum current specified in the specification. If the current exceeds this value, the load must be connected through a contactor (magnetic actuator, power relay), which is optimized for this current (Wiring ).2

EXPLOITATION

Switching on thermostat
To turn on the thermostat, apply voltage to terminals 3 and 4. The display will show «888» for 3 seconds.
Then the sensor temperature will be displayed.
Preset temperature
(factory setting 52 °С )
To view, click on the «+» or «–». The next press on «+» will increase the preset temperature, on «–» it will decrease.
If the preset temperature is lower than the sensor temperature, the heater will turn on and the red indicator will light up.
Function menu
Use the «≡» button to select the desired menu item (see Table 1).
Use «+» or «–» to change parameters. After the first press, the parameter starts blinking. At the next press, the parameter is changed.
5 seconds after the last pressing, the thermostat will automatically return to the air temperature display.
View firmware version
Hold down the «–» button for 6 seconds. After releasing the button, the thermostat will return to normal mode.
The internal overheating protection
If the temperature inside the frame exceeds 80 °С, the emergency power cutoff will take place.

The screen will show the «oht» (overheat) sign once per second. When the temperature inside  the housing drops below 0 °C, the thermostat  will resume operation. After the protection is activated more than 5 times in a raw, the thermostat will be blocked till the temperature inside the frame falls below 60 °С and a button will be activated.
In the case of internal overheating sensor breakout or short-circuiting the device will continue functioning in the normal mode, but each 5 sec the «Ert» sign (a problem with sensor) will be displayed. In this case, the internal overheating control will not be controlled, but the thermoregulator will continue to maintain the preset temperature.
Reset to the factory settings
To reset the factory settings, hold the three buttons at the same time for more than 12 sec until «dEF» message appears on the screen. After release it will reset to the factory settings and reboot.
Table 1. FUNCTION MENU

The screen will display: 1.XXh, where XX is the remaining time in hours, if the time is > 10 h.
2.X.YY, where X is hours, YY is minutes, with alternating ton inscription every 10 seconds, if time is <10 hours
Timer (factory setting «9.0h»,
range 0,5-99 h, step — 0,5 h)| 2 times| | The step of 10 hours is set with the step of half an hour, and for bigger values the step is 1 hour.

POSSIBLE PROBLEMS, CAUSES AND WAYS TO OVERCOME THEM
Load is off, screen and indicator are off Possible cause: No power supply.
It is necessary: make sure that the supply voltage is available. If power supply is available, contact the Service Center.
The thermostat switched to the Emergency Timer mode Possible cause:

• sensor disconnection

• an open circuit in the sensor circuit or the temperature has gone beyond the measured temperatures;

• a source of an electromagnetic field near the sensor wire, which prevents data transmission.
  It is necessary: check the conformity of the sensor connection

• check the connection point of the sensor to the thermostat, as well as the absence of mechanical damage along the entire length of the sensor connecting wire;

•  absence of a source of electromagnetic field near the sensor wire.

Emergency operation as per timer Mode (factory settings 15 minutes)
The «t» symbol will flash on the screen and the remaining time until the next load on / off is displayed. In this case, every 5 seconds the cause of the sensor maloperation «OC» (open circuit) or «SC» (short circuit) will be displayed. Select the load operation time in a 30-minute cyclic interval, the rest of the time the load will be turned off. The load operation time can be set in the range oFF, 1…29 min, on. For the load to work continuously, select «on»; to turn it off completely, select «oFF».
