FAQ
- Q: What is the warranty period for internet devices?
- A: The warranty for terneo devices is valid for 36 months from the date of sale, provided that the instructions are followed. For products without a warranty certificate, the warranty period is counted from the date of production.
- Q: How does the thermostat control heating?
- A: 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.
- Q: What does the flashing dot indicate during relay activation?
- A: If there was less than 1 minute between relay switching, the relay activation will be delayed, marking the countdown with a flashing dot to protect against frequent switching in the thermostat.
- Q: How are settings saved in case of a power outage?
- A: The non-volatile thermostat storage saves all settings in the event of a power outage.
- Q: What is the recommended ambient temperature range for optimal performance?
- A: The thermostat is designed to operate within a standard room temperature range of X°C to Y°C for optimal performance.
Terneo srz 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

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 TOUCH CONTROL OF THE DEVICE IS SENSITIVE to strong electromagnetic fields and interferences (for example, fluorescent lamps, induction furnaces, etc.), close proximity to which may cause false operation of the touch buttons or their blocking. Please take this fact into account when installing.
- DURABILITY AND RELIABILITY OF POWER RELAY CONTACTS is ensured by turning on the load as close as possible to the moment when the voltage sinusoid cross zero point. Small deviations from the zero crossing are possible due to different trip times of different types of power relay.
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-circuits in the load circuit the circuit breaker (CB) has to be
installed before installing the thermostate . 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

POSSIBLE PROBLEMS, CAUSES AND WAYS TO OVERCOME THEM
While the load is running, the symbol « t » flashes on the screen
Possible cause: damage to the sensor and its circuit It is necessary: to check
the integrity of the sensor and the absence of mechanical damage to its
circuit, the absence of power wires that are laid close. Timer-based emergency
operation mode (factory setting
This mode ensures the operation of the thermostat in case of damage to the
sensor: in a 30-minute cyclic interval it turns on the load for the set time,
the rest of the time the load is turned off. The load operating time is
adjustable from 1 to 29 minutes using the orbuttons. To ensure continuous
operation of the load, select and to turn the load completely off, select .
Heating temperature control is not available
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 load does not work, the screen flashes «oht»
- The temperature inside the housing exceeded 80 °C, the protection against internal overheating worked.
Possible cause: internal overheating of the thermostat. It can occur if the socket that powers the device or the plug of the load is not designed for the required power, the ambient temperature is high, or the power of the switched load is exceeded. It is necessary: to make sure that the socket powering the device or the load plug is designed for the required power and the load power does not exceed the allowable one. Features of the protection against internal overheating: when the temperature inside the housing drops below 60 °C, the thermostat will resume operation. When the protection is triggered more than 5 times in a row, the thermostat will be blocked until the temperature inside the housing drops below 60 °C and one of the buttons is pressed.
Every 4 seconds the screen displays «Ert»
- Possible cause: is a break or short circuit of the internal overheating sensor. Internal overheating is not monitored
It is necessary: to send the thermostat to the service center. Otherwise, overheating control will not be carried out.
When you turn on the screen for 5 seconds «Er0» is displayed
- Possible cause: malfunction of the control system for the transition of the sinusoid through zero
It is necessary: send the thermostat to the service centers. Otherwise, the control over crossing of the sinusoid through zero will not be carried out.
SAFETY INSTRUCTIONS
Carefully read and become aware of these instructions. Before the installation (dismantling) and connection (disconnection) of the device, turn off voltage supply and also act according to the «Rules of an arrangement of electric installations».
