IV. Receiver for wireless controller
ST-292v2 regulator communicates with
the heating device (or the CH boiler
controller) via radio signal sent to the
receiver. The receiver is connected to the
heating device (or CH boiler controller)
via a two-core cable whereas the
communication with the room regulator is
performed wirelessly via radio signal.
The receiver has the following control
lights:
• green 1 (1)– indicates data reception,
goes on during channel change;
• red (2)– indicates receiver operation;
• green 2 (3) – goes on when the room
temperature fails to reach the pre-set value – the heating device is switched on.
NOTE
In case of communication failure (e.g. when the battery is flat), the receiver
automatically disconnects the heating device after 15 minutes.
How to change the communication channel
Channel “35” is the default communication channel in the room regulator. The channel may be
easily changed (if the current channel is used by other devices). To change the channel, press
and hold the channel change button (4) for about 10 seconds until the green control light (1) goes
on. Next, change the communication channel in the room regulator following the procedure
described in part VIII.c.10. The green light on the receiver should go off.

V. External temperature sensor
ST-292v2 room regulator may optionally be equipped with an external temperature sensor. The
sensor should be mounted in a shaded place so that it is not affected by the weather conditions.
The current temperature value will be sent to the room regulator every few minutes and it will be
displayed on the main screen.
The external sensor communicates with the room regulator via radio signal. Both the room
regulator and the external sensor are pre-configured to operate on channel “35”, but the user
may easily change the channel (if the current channel is used by other devices).
How to change communication channel:
In order to change the channel, press and hold the channel change button. After the control light
on the sensor flashes, the process of channel change has been initiated. Hold the button and wait
until the light starts flashing again. The number of flashes corresponds to the first digit of the
desired channel number.
Release the button after the desired number of flashes and press it again to set the second digit
of the channel number – the control light flashes quickly twice. Hold the button and wait until the
light flashes the desired number of times. When the button is released, the control light flashes
twice – the new communication channel has been set.
NOTE: In case of a one-digit channel number (channels 0÷9) set 0 as the first digit.
Example 1:
28 is the desired communication channel. In order to select this channel, set the first digit - 2,
and the second digit – 8.
Press and hold the channel change button - the control light flashes quickly once - the process of
channel change has been initiated. Hold the button and wait until the light flashes two more times
(the first digit of the channel number – 28).
Release the button and press it again – the control light flashes quickly twice – the process of
setting the second digit has been initiated. Hold the button and wait until the light flashes 8 times.
When the button is released, the control light flashes quickly twice – the new communication
channel has been successfully set.
Example 2:
7 is the desired communication channel. In order to select this channel, set the first digit - 0, and
the second digit – 7.
Press and hold the channel change button - the control light flashes quickly once - the process of
channel change has been initiated. As the first digit is 0, release the button before the control
light flashes again. Press the button again – the control light flashes quickly twice – the process
of setting the second digit has been initiated. Hold the button and wait until the light flashes 7
times (the second digit of the desired number). When the button is released, the control light
flashes quickly twice – the new communication channel has been successfully set.
In case of errors in the channel change process, the control light goes on for ca. 2 seconds. In
such a case the channel will not be changed.

VII. How to use the controller
VII.a) Principle of operation
The main task of ST-292 room regulator is to maintain the pre-set temperature of the room
by sending a signal to the heating/cooling device (contact opening) when the desired temperature
is reached. In such a situation, the heating/cooling device is switched off (if the regulator is
connected to the CH boiler controller, the CH boiler enters sustain mode).
If the regulator is used in heating mode, it may cooperate with the underfloor heating sensor.
In such a case, the contact remains closed when the floor temperature is below the minimum
threshold. After the threshold value has been reached, the contact remains closed until the preset room temperature is reached. If the floor sensor temperature exceeds the maximum value,
the regulator opens the contact regardless of the current room temperature.
NOTE
In order for the underfloor heating functions to be available in the controller menu,
it is necessary to connect an additional sensor to the floor sensor contact.
VII.b) Operation modes
The user has three operation modes to choose from:
Day/night mode
In this mode the pre-set temperature value depends on the current time of the day. The user may
set different temperature values for the daytime and nighttime (comfort temperature and
economical temperature) as well as define the exact time of entering day mode and night mode.
In order to activate this mode, press EXIT button until day/night mode icon appears on the main
screen.

VII.c.6) Optimum start
Optimum start is an intelligent system controlling the heating/cooling process. It involves constant
monitoring of the heating/cooling system efficiency and using the information to activate the
heating/cooling process in advance in order to reach the pre-set temperatures.
The system requires no user intervention. It precisely reacts to any changes that affect
the efficiency of the heating system. If, for example, some changes have been introduced to the
heating system and the house heats up faster than before, the Optimum start system will
recognize the changes at the next pre-programmed temperature change (from comfort to
economical) and in the next cycle the heating system activation will be adequately delayed,
reducing the time needed to reach the desired temperature.
A – pre-programmed change from economical temperature to comfort temperature

VII.c.9) Floor sensor
NOTE
This parameter is not available in the menu if the additional sensor has not been
connected to the floor sensor contact or when the cooling mode is selected.
This function enables the user to activate the floor sensor. When the floor sensor is enabled, the
contact status depends also on the floor temperature. The contact remains closed (the device is
on) when the floor temperature is lower than the minimum value (regardless of the room
temperature). When the minimum temperature of the floor sensor has been exceeded, the contact
remains closed until the pre-set room temperature
is reached. If the floor sensor temperature exceeds

VII.c.11) Floor temperature hysteresis
Floor temperature hysteresis defines the floor temperature tolerance in order to prevent undesired
oscillation in case of small temperature fluctuation within the range of 0,4 ÷ 5°C. This parameter
concerns both the maximum and the minimum floor temperature.
Example:
Maximum floor temperature = 45°C
Hysteresis = 2°C
Minimum floor temperature = 30⁰C
The room regulator disables the contact when the temperature of 45⁰C on the floor sensor is
exceeded. When the temperature starts falling, the contact is activated again at the temperature
of 43⁰C on the floor sensor (unless the pre-set room temperature has been reached).
With the minimum floor temperature the hysteresis function works the other way round. After the
value of 30⁰C has been reached on the floor sensor, contact opening/closing depends only on the
current room temperature (reaching this value opens the contact). When the floor sensor
temperature drops to 28⁰C the contact closes regardless of the current room temperature.
In order to set the floor temperature hysteresis,
press menu until hysteresis panel appears on the
screen (floor sensor must be activated beforehand
by selecting ON)
Use or to select desired hysteresis value.
Press MENU to confirm and move on to edit the
next parameter or press MENU to confirm and

VII.c.15) Pre-set temperature hysteresis
Room temperature hysteresis defines the pre-set
temperature tolerance in order to prevent undesired
oscillation in case of small temperature fluctuation
(within the range of 0,2 ÷ 4°C).
Example:
Pre-set temperature: 23°C
Hysteresis: 1°C
The room regulator reports that the temperature is
too low only when the room temperature drops to
22 °C.
In order to set the hysteresis, press MENU until the hysteresis setting appears on the screen.
Use or to set the desired hysteresis value. Press MENU to confirm and move on to the next
parameter or press EXIT to confirm and return to the main screen view.
VII.c.16) Temperature sensor calibration
It is performed when mounting the regulator or after it has been used for a long time, if the room
temperature measured by the internal sensor differs
from the actual temperature. Calibration setting
range is from -10°C to +10°C with the accuracy of
0,1°C.
Press MENU until the sensor calibration panel
appears on the screen. Use or to define
correction. Press MENU to confirm and move on to
edit the next parameter or press MENU to confirm
and return to the main screen view.
