Technical data sheet and installation and operation manual

• Terneo rz thermostat is designed to maintain constant temperature within the range from 0 to 30 °C using heating or cooling equipment.
• According to the data from the temperature sensor, the thermostat turns off the heating when the desired temperature is reached and turns it on when it drops by the hysteresis value.

IN THE BOX

• Thermostat 1 piece
• Technical data sheet and installation and operation manual and warranty card 1 piece
• The packing box 1 piece

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.
• RELIABILITY OF THE POWER RELAY provides protection against frequent switching in the thermostat. If there was less than 1 minute between relay switching, the relay activation will be delayed, marking the countdown with a flashing dot.
• NON-VOLATILE THERMOSTAT STORAGE saves all settings in the event of a power outage.
• THE TEMPERATURE CONTROL LIMITS AND HYSTERESIS CAN BE EXPANDED in the thermostat advanced menu (see page 6).
• IT IS FORBIDDEN TO POWER THE DEVICE FROM SOURCES WITH A MODIFIED SINUSOID, as well as uninterruptible power supplies, the output voltage of which is not a sinusoid. Long-term  operation, more than 5 minutes, from such voltage sources may damage the device and lead to out-of-warranty repairs.

CONNECTION

The fork of terneo rz plugs into a standard wall socket 230 V ~ 50 Hz with grounding. The socket must designed for a current of at least 16 A. The design of the socket should provide a reliable contact.
In order to connect the thermostat:

• Connect the thermostat in the socket;
• Connect the load to the thermostat socket.
  It is necessary that the thermostat commutes the current not more than 2/3 of the maximum power specified in the passport.

INSTALLATION

• The thermostat is designed for indoor installation.
• The ingress risk of moisture or liquid into the place of installation must be minimized.
• 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. It should be designed for not more than 16 A.
• It is prohibited the use of a thermostat inside the greenhouse to prevent oxidation of outlet contacts, which can lead to damage to the device.
• To protect person from electric shock leak is set SSD (safety shutdown device).
• The cross section of the wires connected to device should correspond to the amount of electric current consumed by the load.

EXPLOITATION

• Use the «≡» button to select the desired menu item.
• Use  «+» or «–» to change the parameters. The first press causes a flashing of the parameter, the next one a change.
• Temperature display returns after seconds after the last pressing the button

Switching on the thermostat

When you turn on the screen displays «888» and then the sensor temperature. The red indicator lights up to indicate that the load is on.

Preset temperature

• (factory setting 23 °С)
• Use «+» and «–» to select the temperature. If sensor fails, the thermostat will continue to operate in emergency timer mode (details on page 7).

Button blocking
(child and public protection)

• In order to enable disable button blocking press the «+» and «–» buttons at the same time for 6 seconds till the «Loc» sign appears on the screen.
• Resetting to factory settings
  • To reset, hold down three buttons and hold for more than 12 seconds «dEF». inscription will appear on the screen. After releasing the buttons, the screen blinks off and the thermostat restarts.

Firmware version view

• Holding the button  «–» for more than 6 seconds will display the firmware version on the screen. After releasing the button, the thermostat returns to the normal operation mode.
• The manufacturer reserves the right to modify the firmware to enhance the device technical characteristics.
