English 3. Brief description of the IRT 30 3.1 Introduction The IRT 30 clock thermostat has been specially developed for the use with boilers fitted with the universal burner auto unit UBA4000.The IRT 30 is designed for wall-mounting and is powered via a connection to the boiler.Thus, the thermostat does not use any batteries. By making use of a computer program, the thermostat continuously receives data from the boiler and the other way around.
English 3.2 Selecting the correct kind of temperature regulation In paragraph 3.1 the three kinds of temperature regulation for which the IRT 30 is suitable, are mentioned: - room temperature controlled regulation - weather dependent regulation - weather dependent regulation with room temperature compensation.
When to apply the room temperature controlled regulation? - When the house is heated only by means of radiators. When not to apply the room temperature controlled regulation? - When there is no appropriate reference room in the house to install the IRT 30. - When your house is heated (also) by means of floor heating, air heating or convectors. In practice, the room temperature controlled regulation is the principle which will be selected in most cases.
English In a house which is heated by floor heating, the temperature fluctuations should not become too large. Furthermore, this kind of heating heats up and cools down very slowly. In this situation, weather dependent regulation is a good choice, because with this regulation the heating intensity of the boiler will only be affected by the outside temperature. Because of this, changes will take place relatively gradually.
What does weather dependent regulation with room temperature compensation mean? - The CH water temperature will be determined, in first instance, by the outside temperature and the preset values in the IRT 30. - The IRT 30 also measures the temperature in the room where it is fitted. - On the basis of the measured room temperature, the IRT 30 adapts the water temperature of the CH automatically. - The rooms will be heated by the continuously circulating water.
English 3.3 Operating controls The IRT 30 can be controlled on two levels (refer to the fold-out page, figure A and B): 1. With the flap closed (figure A); you now have access to: - The temperature adjustment knob, for manual adjustment of the temperature, - the + and – push buttons, for temporary adjustment of the temperature within the clock program. – + 2.
clock program is shown boiler heats the CH water (hot water supply ON) Boiler heats CH water according to clock program (hot water supply AUTO) CH boiler ON room temperature controlled regulation is active weather dependent regulation is active weather dependent regulation with room temperature compensation is active CH boiler OFF automatic summer/winter mode (only when outside temperature sensor is connected) each block 0.
English During programming, the display shows information about the switching points of the program. In rest (normal mode), the following is shown on the display: figure 3-2 Display in rest 4. Operation 4.1 General Read this manual carefully, so you can operate the IRT 30 correctly.Your installer can inform you in detail about the use of the clock thermostat.
Maintenance - Clean the IRT 30 using a dry cloth. - Do not use any liquid or cleaning agents.This may cause short-circuiting or damage to the thermostat. manually Outside temperature - If you select the weather dependent regulation (with or without room temperature compensation), you need an outside temperature sensor, which is connected to the boiler. - Without the outside temperature sensor, only the room temperature controlled regulation can be used. 4.
English If the thermostat is set to weather dependent regulation and you turn the temperature adjustment knob out of the AUTO-mode, the thermostat will function as for weather dependent regulation with room temperature compensation. On the screen, the symbol of weather dependent regulation will be replaced by the symbol for weather dependent regulation with room temperature compensation (also refer to page 9). 4.
You can check the switching points by slowly turning the program knob.You will see the day number, time and temperature for each switching point. Looking to the clock program, you can see a clock in the left upper corner of the display. As soon as you change a setting in the clock program, the clock symbol starts blinking. The IRT 30 is supplied with a standard clock program.
English In the standard clock program for the weather dependent regulation you do not find temperatures, but scale points. One point of the scale corresponds with a temperature range of 0.5 °C to 2 °C.The calculation starts at 0, which corresponds with a standard room temperature (20 °C). Consequently: – 1 means 18 - 19.5°C and + 1 means 20.5 - 22°C. 1 point does not correspond with 1 °C.
English 4. Change the temperature as follows: - Press and hold the TEMPERATURE key. - Change the time using the program knob. - Release the TEMPERATURE key. – + + You have now changed a switching point. After a few seconds, the display shows the actual time and the measured room temperature (normal mode). Inserting an arbitrary switching point If you want to have more switching points in your clock program, do the following: 1. Make sure the display is in normal mode (refer to figure 3-2). 2.
English 8. Press and hold the TEMPERATURE key and select a time using the program knob. – + + 9. Release the TEMPERATURE key. You have inserted a switching point. Inserting a switching point at the current time You can also insert a switching point at the current time: 1. Make sure the display is in normal mode (refer to figure 3-2). 2. Press and hold the INSERT key and change the temperature using the program knob.The temperature indication is blinking. – + + 3.
– 1..7 + + + Copying is shown by a dash which moves from left to right in the display (2 steps). As soon as the settings have been copied, the display shows two dashes left of the day number. 3. Release the DAY and the INSERT key. Return to the standard clock program It is always possible to return to the standard clock program.This will erase all other switching points. 1. Make sure the display is in normal mode (refer to figure 3-2). 2. Press and hold the TIME, REMOVE and INSERT key.

4. Mount the mounting plate onto the wall Make sure the power supply of the boiler is switched off! figure 5-1 figure 5-2 figure 5-3 1. Remove the old thermostat if you want to replace it by the IRT 30. 2. The mounting plate can be fitted to a standard terminal box or directly to the wall. 3. Remove the mounting plate from the thermostat. At the bottom side of the thermostat are 2 right-angled slots. Here, the click-on latches are located.
English 5. Connect the wiring Make sure the power supply of the boiler is switched off! figure 5-5 1. Connect the wires onto the mounting plate by fitting them behind the clamps (refer to figure 5-5). It is not important which wire is connected to which clamp. 2. Push the wires back into the hole in the wall if the wires are too long. Fill the hole in the wall with filler to prevent draught affecting the operation of the thermostat. 3.
English 5.2 Testing the thermostat Switch on the power supply of the boiler. The thermostat automatically completes a start-up and test program: - First, the display is empty. - During 3 seconds all symbols will be shown on the display (also refer to figure 3-1). - Subsequently, the version number of the software will be shown on the display. - After this, a few tests will be executed. During the first tests, EE will be shown on the display.
English 6. Setting the temperature control 6.1 Selecting a temperature control The IRT 30 thermostat is suitable for 3 kinds of temperature control: - Room temperature controlled regulation (RR) - Weather dependent regulation (WD) - Weather dependent regulation with room temperature compensation (WD + RTC) Select one of these control before you continue. Chapter 3 describes the points of attention for making your choice.

This causes the thermostat to run the start and test program again (refer to paragraph 5.2). + + You can reset the thermostat as follows: 1. Simultaneously press the MENU, INSERT and REMOVE key, and release them. 2.
English Calibration of the temperature sensor of the thermostat The temperature sensor in the IRT 30 thermostat should be calibrated when the measured temperature, shown on the display, deviates from the actual temperature. It is no simple task to determine the actual temperature in the room.The position you are measuring and the accuracy of the thermometer you are using may influence the result. It is also important to measure the temperature when the temperature is stable, (i.e.
– 4. Turn the program knob, while holding the MENU and REMOVE keys, until the blinking temperature reflects the temperature onto which the temperature adjustment knob is set. 5. Release all keys when you are finished. + Calibration of the outside temperature sensor The outside temperature sensor should be calibrated when the measured temperature shown on the display, deviates from the actual outside temperature at the outside temperature sensor.
English 9. Malfunctions and the display codes of the boiler In this chapter, some possible problems/malfunctions will be described. Furthermore, the possible solutions will be given.You can always contact your installer if the problems persist. For some items, the solution depends on the set kind of regulation.
The room becomes too warm (warmer then the set temperature). 1. Is the IRT 30 thermostat able to measure the correct temperature (only for RR and WD + RTC)? Is the IRT 30 thermostat installed on a cold outside wall or in stream of draught? 2. If the rooms have been equipped with too many or too large radiators, the house can also be heated with water of a lower temperature.The maximum temperature setting of the water can be reduced on the UBA. 3.
English Energy consumption is too high (higher then old boiler) / the boiler burns too often or too long. 1. Is the room heated while it is not in use? Insert more switching points with a lower temperature to the clock thermostat. 2. Is the capacity of the new boiler higher then the capacity of the old boiler? 3. Have you replaced an old geyser by a combi boiler? A combi boiler can produce more hot water (more comfort) but also uses more energy. 4.
Malfunction of the communication 1. Is the wiring of the IRT 30 thermostat connected to terminal 3 and 4 of the terminal block in the boiler? 2. (only for WD and WD + RTC) Has the correct wiring (preferably 0.75 mm2), for connection of the outside temperature sensor, been used. Does the wiring run along a 230 V power supply cable? 3. Is the cable defective? You can check this by connecting the IRT 30 thermostat directly to terminal 3 and 4 of the boiler, using a short cable. 9.
English Other codes: - Malfunction of the sensors. On the display appears: - the symbol of the mechanic - three blinking dashes (on the position of the temperature indication). - the symbol of the room temperature, or the symbol of the outside temperature, indicating which sensor is malfunctioning (refer to figure 9-2 and 9-3).
Switching point A switching point is a setting in your clock thermostat. It is a moment in time at which you desire a different temperature. To set this, you have to enter the desired time and the desired temperature. Reference room A reference room is a room (for example the living room) where a temperature can be measured which is representative for the entire house. We assume, that the temperature in other rooms (for example kitchen or bedroom) is equal to the temperature in the reference room.
English Weather dependent (temperature) regulation with room temperature compensation This is one of the ways to regulate the temperature in your house.With this principle, the CH water temperature (and the intensity of burning of the boiler) is determined, in the first instance, by the outside temperature and the preset values on the IRT 30. However, the thermostat also measures the temperature in the room where it is fitted.
