Product Features

Working under load up to 16A
AURATON RTH receiver is equipped with a relay that can operate under load up to 16A and the technology of low-spark switch (negligible wear of relay contacts).

Interference free communication between devices
AURATON 2025 RTH operates at a frequency of 868 MHz with extremely short (4 ms) encrypted transmissions , which ensure smooth and interference free operation (4 billion codes).

Memory algorithm cycles on / off
AURATON RTH receiver is equipped with a unique algorithm which analyzes on-off cycles. The entire heating cycle of the last 24 hours is stored in the receivers memory. In case of loss of communication with the transmitter, the receiver will automatically start remembered program of the last 24 hours on/off cycle. This gives time for the restore transmission (removing interference) or repair the regulator without significant deterioration of thermal comfort in controlled room.

Backlit LCD display
With the backlit display, we can oversee the operation of the device even in a dimly lit room

Light sensor
To increase battery life thermostat is equipped with a unique function – light sensor. In a dark room the screen will go blank. Pressing any button or more than 1 lux light turns a screen on again.

Enhanced vacation mode
From 1h to 99 days with an independent temperature.

Basic elements of the system

AURATON 2025 RTH - Wireless thermostat set.

AURATON RTH - Receiver.
The receiver – AURATON RTH – mounted by the heating or air conditioning unit, is equipped with a relay that can operate under load to 16 amps. Because wireless cooperation with temperature controller it does not require additional installation work associated with bringing the wires from the controller to the receiver. Synchronization of AURATON 2025 temperature controller and a receiver AURATON RTH RTH is extremely simple and is limited to pressing a button on each of the elements of the system. With LED indicators you can easily monitor the status of operation.

Additional elements of the system (are purchased separately)

A receiver AURATON RTH can work with additional , wireless devices ensuring a temperature comfort in a building and energy consumption savings at once.
(additional units are equipped with a pre-installed battery ensuring an operation up to 20 years)

AURATON H-1 - window handle (sold separately)
The optional element of a system is a window handle equipped with a transmitter and its position sensors. It enables to indicate the status of a window.
A handle sends signal to the receiver RTH, which stimulate a relay to operation, for example after switching the heating appliance on, when a window is open or decreasing the temperature at 3°C when a window is raised. It enables to safe an energy. Receiver can support(control) up to 25 handles

AURATON T-2 - thermometer (an element sold separately)
This optional element of a system enables to control the temperature in different rooms than the one in which a controller AURATON T-1 is placed.
Example: We want to adjust a temperature in a children room to 22°C. But we don’t want the children to have a possibility of changing the temperature. In this case it is required to install the thermometer AURATON T-2 in a children room, and a controller AURATON T-1 for example in a kitchen. This enables to keep the temperature in children room amounting 22°C, regardless of temperature fluctuations which occur in the kitchen.

Operation with heating devices- possible configurations

2025 RTH

Temperature control in a place where a wireless temperature controller 2025 RTH is placed.
Basic configurations, essential for controlling the heating device. Pairing a receiver AURATON RTH with a wireless temperature controller AURATON 2025 RTH gives a possibility to set the temperature manually and control it in a place where the controller is installed.

2025 RTH + T-2

Controlling of the temperature in another room, that the one in which the controller 2025 RTH is installed.
If the receiver RTH will be paired with controller 2025 RTH and thermometer T-2, it will be possible to control a temperature in another room(different from the one where a controller is installed)
Example: We want to adjust a temperature in a children room to 22°C. But we don’t want the children to have a possibility of changing the temperature. In this case it is required to install the thermometer AURATON T-2 in a children room, and a controller AURATON 2025 RTH for example in a kitchen. This enables to keep the temperature in children room amounting 22°C, regardless of temperature fluctuations which occur in the kitchen.
.

2025 RTH + H-1

Controlling of a temperature in cooperation with window position sensor
This setting allows to control the temperature in a room, taking into account a window position status.

window closed – a temperature control is normally done,
window raised – a receiver RTH decreases a temperature at 3°C,
window open( for more than 30s.) - a receiver RTH will switch off the heating system.

2025 RTH + T-2 + H-1

Controlling of a temperature in cooperation with window position sensor( in another room)
It enables to control the temperature in different room than the one in which a controller AURATON 2025 RTH is placed, taking into account a window position status.
