Selecting the place of thermostat installation

The thermostat is designed for indoor installation. No cables are connected to the thermostat, thus it can be placed anywhere. To ensure fully efficient operation of the thermostat, please make sure that the following recommendations regarding the location of the thermostat are observed:

• Locate the thermostat at the height of approximately 1.5 m above the floor Avoid places exposed to intense sunlight, situated near heating or cooling devices, directly by doors, windows, and other similar locations, where the temperature measurement could be easily disturbed by external conditions.
• Avoid places with poor air circulation, e.g. behind furniture.
• Avoid moist places due to the negative effect of moisture on the service life of the device.

Installation of the receiver

Insert the receiver into the 230 V power socket, as close as possible to the controlled device. The Wi-Fi module is built-in inside the receiver, thus you should ensure that the receiver is within the range of the Wi-Fi signal. You should also check the strength of the radio signal between the thermostat and the receiver.

Insertion and replacement of batteries

Place the batteries in the thermostat while observing their correct polarity. There are installation markings in the battery compartment. Then install (snap) the thermostat onto the base.

CAUTION! Use only alkaline AAA batteries to power the thermostat. Do not use rechargeable batteries because their voltage is lower and their effective time is shorter.

It is recommended to replace batteries before each heating season.

Switching the thermostat off

Hold the central button until the thermostat is switched off (approximately 5 seconds). Switching the thermostat off holds the temperature control indefinitely – a clock, weekday, current room temperature, and icons are displayed. To restore temperature control hold the central button again for 5 s

Battery saving – ECO mode

When using the thermostat in the heating mode only, you may activate battery saving mode. Put the operation mode switch in the ECO position. The date and time will not be displayed, the time of thermostat response to the changes sent to and from the application will lengthen to 20 minutes. The weekly program will operate normally.

Manual (temporary) temperature change

The manual override function enables a temporary change of temperature without introducing changes in a program. The thermostat will operate according to the new temperature setting throughout the current program. With the beginning of the subsequent program the manual override is completed and the thermostat restores operation according to programmed temperatures.

To activate manual override set the desired temperature using buttons. At this point, the manual override icon is displayed. To finish the manual override earlier press the left button.

Temperature level modification

Two temperature levels are available in the thermostat: comfort temperature and economical
temperature. These temperatures apply for all days of the week. Temperature values may be changed freely within the range of 5 °C…35 °C (in cabled sensor mode: 5 °C…85 °C). Factory
settings are the following: comfort temperature 21 °C, economical temperature 20 °C. To modify the temperature go to the menu, select item, and use the central button to select the temperature to be modified. Use buttons to set the desired temperature. The longer the button remains pressed, the quicker the values change. Exit the menu by pressing button or holding it for a few seconds.

Weekly program

A separate period is provided for each day of the week. Select  item in the menu. Abbreviated names of weekdays are displayed. Use the central button to tick a day or individual days to be modified (if an identical program is to be set for them). Use the right button to enter the period.
Use the left button to set the period for economical temperature and the right button to set the
period for comfort temperature. Whenever you press a button the temperature is programmed
for 0.5 hour.

Use  buttons to change the period of the range without changing the program, e.g. if it is  necessary to correct the program. Confirm the introduced modifications with the central button. Exit the menu by pressing button or holding it for a few seconds.

Temperature maintenance – constant temperature

The thermostat maintains the preset temperature regardless of the preset weekly program. To
activate operation with constant temperature setting go to the menu and select . Use buttons to set the desired temperature. Confirm the entered temperature with the central button. The constant temperature icon is displayed. At this point, the thermostat starts operating in constant temperature mode. To restore operation according to the weekly program, switch off the constant temperature function.

Vacation mode

Maintenance for a vacation period is used to set the desired temperature for the time of being away on vacation. It will allow you to significantly reduce heating system energy consumption. To switch to vacation mode go to the menu and select . Use buttons to set:

• the year when the vacation commences; confirm it with the central button
• the month and day when the vacation commences; confirm them with the central button
• the hour when the vacation commences; confirm it with the central button
• the year when the vacation ends; confirm it with the central button
• the month and day when the vacation ends; confirm them with the central button
• the hour when the vacation ends; confirm it with the central button
• the temperature applicable throughout the entire vacation mode period.

Confirm the settings with the central button. Upon its commencement, the vacation mode icon is displayed.

THERMOSTAT SETTINGS

In this menu you may change and select the following functions:

• Date/time
  The date setting sequence is year > month > day. Using  buttons select a year. Confirm with the central button. Set a month and day. Follow the same procedure to set hours and minutes.

• Weekday language
  The thermostat may display weekdays in Polish, English, or using universal symbols, where 1 stands for Monday, 2 for Tuesday, etc.

• Hysteresis/PWM
  Two operational options of activating the heating (cooling) algorithm are available:
  hysteresis or PWM.
  In the case of hysteresis, the device is activated based only on a difference between the
  preset and current temperature. To set hysteresis go to the menu and select , then
  select . Use buttons to change the hysteresis value (the range is 0.2 °C… 10 °C; the factory setting is: 0.2 °C).
  PWM ( ), is a more advanced method to achieve the preset temperature. It is suited for systems with underfloor water heating. It is used to limit room temperature fluctuations. Unlike in on/off controls the current status of the transmitter depends not only on the current difference between the preset and measured temperature but also on the past changes of temperature. For example, if the measured temperature is lower than the preset temperature for a long period, the thermostat switches the heating device permanently on. To activate this function it is necessary to set three additional operation parameters:
  ✓ CPH – maximum number of cycles per hour (3-10). The thermostat calculates the number of switch-ons and switch-offs (cycles) per hour (according to temperature changes).
  ✓ CON – cycle duration period (2-10). It is the minimum period (minutes) for which the thermostat switches the transmitter on each time.
  ✓ PB – control bandwidth (0.5 °C…3 °C). If the difference between the preset and measured temperature is included in the proportional control band, then the thermostat selects the switch-on and switch-off times. Outside of this band, the output is in continuous on or off operation.

• Heating in advance
  Activating this function results in switching the heating on earlier to obtain the preset temperature at the required time. The time of advance in switching the heating on is calculated with an advanced algorithm, taking into account previous room heat-up
  times and the current temperature read-out. It takes the thermostat several days to calculate times for various temperatures correctly. To activate this function go to the thermostat menu and select .

• Thermostat interlock
  The thermostat features a setting interlock function. A four-digit code of your choice
  may be entered. In such a case it is not possible to change the settings. A setting interlock does not affect the thermostat operation. To activate the interlock go to the setting menu and select , then use the keys to enter your code. Activating the interlock is signaled with icon. Follow the same steps to unlock the thermostat. This function is not active by default.

SERVICE SETTINGS

The service menu permits thermostat configuration according to the type of system. We suggest that you exercise special prudence when modifying these settings, because inappropriate settings may result in improper functioning of the system or, in extreme cases, lead to damaging system components.
To enter service settings press and hold for 5 seconds two buttons – the central and right buttons. The window presented below is displayed. Service settings are unavailable when the thermostat is switched off or batteries are flat. Navigate the menu the same way you did in previous windows. The service menu consists of the following elements:

• Air conditioning
  Having selected air-conditioning mode the device connected to the thermostat will be switched on when the temperature increases above the preset level.
  In air-conditioning mode, the function of the thermostat power switch changes and the switch is used to select between heating and cooling. Activating the air-conditioning operation enables the preset ranges to be replaced with different ones – the ranges stored for cooling. Returning to heating functions restores the previous ranges. This function enables the thermostat to operate with air-conditioning and heating without losing the settings. The icon of the switched-on device also changes.

• Selection of temperature sensor
  This option permits the selection of a temperature sensor to cooperate with the thermostat. There are three operation modes available:
  ✓ the thermostat measures and maintains the temperature based only on internal sensor operation
  ✓ the thermostat measures and maintains the temperature based only on external (cabled) sensor operation
  ✓ the thermostat measures the temperature of both sensors; it maintains the temperature of an internal sensor, and the external sensor acts as a temperature limit. Having selected this operation mode set the floor temperature limit value. This parameter is used to establish the maximum safe floor temperature. When the preset temperature is reached, the device gets switched off.
  ✓ Temperature sensor correction. It is used to adjust the read-out within the range of +/- 5 °C. The function is convenient if the thermostat is located in a slightly warmer or cooler area of the room. Press the central button to introduce a change. Use buttons to set the new value. Confirm with the central button.
  

CAUTION! The floor temperature sensor is not included in the basic kit. Please order it separately. Connecting the sensor requires changing the thermostat base, therefore wall-mounting becomes necessary.

• Wi-Fi
  Enables checking the MAC address of the device.

• Pairing mode
  It is used to establish the radio connection between the thermostat and the receiver. Pairing mode is described in point 8.1.

• Test Mode
  In the test mode you may check the main parameters of the kit:
  ✓ Program version and compilation date
  ✓ RX receiver relay operation – use button to change the status of the relay
  ✓ Internal sensor temperature measurement
  ✓ Cabled sensor temperature measurement (if installed)
  ✓ Backlight operation – use to switch it on/off
  ✓ Light sensor operation
  ✓ Strength of the radio signal between the thermostat and the receiver (transmission and reception)

• Reset
  By selecting and confirming this item you restore the thermostat factory settings.

RX RECEIVER SETTINGS

Establishing the connection between 4040 Smart thermostat and 4040RX

Smart receiver

Each thermostat and each receiver have a unique number distinguishing them from other ones. It is not possible for any thermostat not paired with the particular receiver to interfere with the operation of another pair or set.
The thermostat may be paired with the receiver again at any time. A blackout, battery replacement as well as a complete reset of all thermostat settings do not affect the pairing of devices in any way.

Pairing procedure:

• Enter the service setting mode in the thermostat
• Select pairing mode
• Insert the receiver in the power socket
• Press the receiver button 3 times – the blue LED will light up
• After detecting the receiver digit 1 (the first receiver) will be displayed
• Press the central button and exit the menu Pairing mode will be finished.

Caution!
Pairing mode is available for 10 minutes after inserting the receiver into the power
socket!
Factory-established pairs are paired, however, pairing may be repeated if necessary. 

Selection of operating mode

While holding its button pressed, insert the receiver into the power socket. Depending on the preset mode a green or red LED will light up. Each time the button is pressed the operating mode changes. When the mode is selected the receiver restores operation.
Green – normally open mode (COM – NO). It is the mainly used operation mode. While the device operation indicator is active, the output cables are shorted.
Red – normally closed mode (COM – NC). While the device operation indicator is active, the output cables are opened.

Caution! Normally open mode (COM – NO) is the factory setting.

FIRST START

When the receiver is plugged into the power socket it signals the relay operation mode. Flash of the green LED – normally open mode (COM – NO), flash of the red LED – normally closed mode (COM – NC).
Each change of the thermostat status (switching the heating on/off) is implemented immediately, whereas the signalization confirming reception of the transmitter radio signal is repeated every 15 minutes.

Radio signal strength

Information on the strength of the radio signal is shown with the confirmation of transmitter signal reception. Reception of the radio signal is confirmed with the green signal. Three flashes of the LED stand for a very strong connection, two flashes – good connection and one flash – sufficient connection.

No radio communication

If the communication between the thermostat and the receiver is interrupted (e.g. due to discharged batteries) and such a condition lasts for 60 minutes (no response from the receiver), the receiver will switch to the anti-frost mode. The heating device will be switched on for 20 minutes every 3 hours, to prevent extensive cooling of the rooms. At the time of reestablishing communication (replacement of batteries), the receiver switches the system off and automatically resumes operation.
No radio communication is signaled with the green diode flashing fast.

Continuous operation of the heating device (MAN)

In the case of system damage, it is possible to switch the heating on manually. Move the switch on the RX receiver to the MAN position. Such status is signaled with red (in the heating mode) or blue (in the cooling mode) LED flashing fast. Additionally, the “RX MANUAL” message is displayed on the thermostat.
