Product Usage Instructions

Before installing and operating the Terneo Smart Control of Heating K2, it is important to read the entire instruction manual to avoid possible danger, mistakes, and misunderstandings.

Wiring

The thermostat supports two types of sensors: analog sensor (R10, default) or digital sensor (D18). When wiring, it is important to note the following:

• The thermostat terminals are designed for a wire with a section not more than 2.5mm2.
• To reduce the mechanical loads on the terminals, it is desirable to use a soft wire. The ends of the wires must be cleaned and crimped with ferrules with insulation.
• The wires are tightened in the terminals using a screwdriver with a blade width no more than 3mm. Using a screwdriver with a blade width more than 3mm can cause mechanical damage to the terminals and may result in the loss of right for warranty.

Installation

The thermostat should be mounted in a special cabinet that allows accessible installation and operation. The cabinet must be equipped with a standard 35mm mounting rail (DIN-rail). The temperature controller has a width of three standard 18mm modules.
The installation height of the thermostat should be in the range of 0.5 to 1.7 meters above the floor level.

The thermostat is mounted and connected after the installation and load testing. To protect from short circuits and excess power events 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 in Wiring 1.

It is important to minimize the risk of moisture or liquid ingress into the place of installation. When installed in a bathroom, toilet, kitchen, or swimming pool, the thermostat should be installed at a place out of reach of casual spraying.

Technical data sheet and installation and operation manual

Terneo k2 thermostat comprises two independent thermostats in one housing. Each of them is designed to maintain a constant temperature from –20 … +100 °С using heating or cooling equipment.

The temperature is controlled at the location of the temperature sensor. If both terneo k2 temperature sensors are located in the same place, one for heating control and the other one for cooling control, then a comfortable temperature in the room can be maintained all year round.
The control of a water-heated floor is carried out using an electrothermal servo drive 230 V. The servo drive can be normally closed or open. Use wiring 2 to connect a normally open servo.

The analog sensor of channel 1 «Ch1» is connected to terminals 1 and 2, and the analog sensor of channel 2 «Ch2» is connected to terminals 7 and 8. The colors of the wires do not matter when connecting.
Digital sensor of channel 1 «Ch1» is connected with white wire to terminal 1 and yellow/red wire is connected to terminal 2. White wire of channel 2 «Ch2» is connected to terminal 7, and yellow/red wire is connected to terminal 8. In the thermostat function menu, select the type of sensor: d18 (see Table 1 menu item «Sensor type»).
The supply voltage (230 V ±10 %, 50 Hz) is supplied to terminals 6 (zero, N) and 12 (phase, L).
Terminals 3, 4, 5 are used to control channel №1 «Ch1 and terminals 9, 10, 11 are used to control channel №2 «Ch2».

Product  INSTALLATION

The thermostat is designed for indoor installation. The ingress risk of moisture or liquid into the place of installation must be minimized. When installed in a bathroom, toilet, kitchen, swimming pool the thermostat should be installed at a place out of reach of casual spraying.
The ambient temperature during installation must be between –5 … + 45 °C.
The temperature controller should 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 installation height of the thermostat should be in the range 0,5…1,7 m above the floor level.

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.
The thermostat terminals are designed for a wire with section not more than 2,5 mm2. To reduce the mechanical loads on the terminals it is desirable to use a soft wire. The ends of the wires must be cleaned and crimped with ferrules with insulation. 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.
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 3).

The cross-section of copper wiring to which the temperature controller is connected should be at least 2 × 1,0 mm2.

Wiring 1. Connecting each channel to a separate load

Wiring 2. Connecting a normally open servo drive on the example of channel 1

CONNECT APPROPRIATE PHASES TO THE CONTROL RELAY k2 for switching, since the relay contacts do not have a galvanic connection with the power supply circuits, that is, the relays used in the thermostat have a «dry normally open contact» (see wiring1).

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.

Wiring 3. Using a contactor to increase the switching power of the channel

MOUNTING OF THE SENSOR MUST BE PERFORMED SO THAT IT WAS POSSIBLE TO EASILY REPLACE IT.
