USER GUIDE

The Chronotherm Modulation is designed to provide automatic time and

temperature control of heating systems. These instructions explain how to

program and operate your Chronotherm Modulation.

Chronotherm Modulation can be used with all OpenTherm

compatible boilers.

The OpenTherm

compatible boilers are marked with OT logo shown below.

Chronotherm Modulation is a programmable thermostat that controls your heating

system so that you can have comfortable temperatures when you are at home and

energy savings when you are out. To ensure that your heating system is operating

in most efficient way Chronotherm Modulation not only switches the boiler on and

off but also modulates the flame to finely match the heating output of the heating

appliance to the current heat demand.

To maximise energy efficiency Chronotherm Modulation has build -in Adaptive

Intelligent Recovery function Instead of switching the heating on at the set time

every day, the controller will delay the start time to the latest possible moment, so

that unnecessary heating is avoided. All you have to do is set the time by which

you want to be warm and Chronotherm Modulation will then decide when to turn

the heating on.

1 Day button allows you to set correct day of the week.

2 The display continuously shows information about time, day of the week and

temperature. The Energy meter allows you to see the current firing rate of the

boiler. A radiator or tap symbol is shown when boiler is servicing central

heating or domestic hot water.

3 These buttons are used to adjust the temperature level. You can operate

these buttons also when the flap is closed.

4 “

” Enquiry button is used to display the set room temperature level and the

outside temperature (only if the outside temperature sensor is connected to

your boiler).

5 The holiday function allows setting of a setback temperature for a period of

maximum 99 days. The same function can also be used as timed program

override providing energy savings or extended comfort period.

6 These buttons are used to program up to six temperature changes per day.

7 Slider position defines the operating mode. When slider is set to AUTO the

Chronotherm will operate according to the program.

8 Time adjustment buttons are used for clock and temperature change

settings.

9 The copy button allows you to copy the time/temperature program to the next

day.

SPECIAL FUNCTIONS

Modulating control

The Chronotherm Modulation continuously adapts the firing rate of the boiler to

the required heat demand. This results in a very accurate control of the room

temperature. The modulating control is only possible if the heating appliance is

supporting OpenTherm

communications.

OpenTherm

communication

The Chronotherm Modulation exchanges information with the heating appliance

using OpenTherm

two-way communication protocol.

NOTE: The amount and type of information that can be displayed as well as

appliance specific information codes may vary.

Refer to the user manual of the appliance for this specific information.

Optimizing through the intelligent adaptive recovery (AIR) feature.

To achieve the required temperature in the house we typically set the on time for

the heating system earlier than required. In this way we can be sure that we will

have the comfortable temperature when we wake up. As we never can guess

precisely when the heating should come on we tend to stay on the save side

setting the on time earlier then required. Consequently we have to pay for keeping

the house at comfort temperature longer then necessary. The Chronotherm

Modulation solves this problem completely. It checks every day how much time is

required to heat up your home. Using this data the Chronotherm Modulation

calculates the precise moment when to start the heating up the next day to

achieve comfort temperature exactly when you want it. Consequently you do not

have to take the warm up time into account when programming. The Chronotherm

Modulation activates adaptive intelligent recovery function before every

programmed temperature level increase.

NOTE: After installation Chronotherm will require a couple of days to learn how to

calculate ON times for a particular house.

Program up to six time/temperature periods per day.

You have the possibility to set 6 different periods for each day of the week. The

time/temperature periods are marked with numbers 1 to 6.

The start time and temperature level for each period is programmable within the

temperature setting range of 5 to 30°C.

Backup during power supply failure

Your Chronotherm Modulation operates without batteries. The power is supplied

through the communication connection. In case of the mains power loss a

rechargeable backup power supply is sufficient to keep the program and the clock

settings for at least 8 hours. If the backup supply is exhausted the display will be

blank and the individual program will be deleted. After the mains supply has been

reestablished the factory program will be activated and the display will flash at

12.00. It will take between 10 and 60 minutes (dependant on the operating

conditions) to charge the backup supply.

The energy meter

If the burner of the boiler is energized, a bar of flames will be shown on the left

side of the display. This allows you to check at all times at what firing rate your

boiler is operating. (The percentages in the above graph are indicative only.

Dependant on the modulation band of your boiler the in between values may vary)

The radiator or tap symbol indicates if energy is being used for central heating or

the domestic hot water (if applicable).

Unique holiday/timer function

The holiday button allows you to override your normal temperature profile and set

the fixed temperature level for a defined time. You can set the required

temperature for as long as 99 days or as short as 1 hour.

Intelligent DHW control

If you own a boiler that also provides hot water (combi boiler) then the

Chronotherm Modulation can provide additional savings.

In the FROST PROTECTION or HOLIDAY/TIMER function, the Chronotherm

Modulation will switch off the DHW function or (dependant of the appliance) will

switch to a savings mode. In this way the DHW storage will not be kept on a high

comfort temperature if this is not necessary.

If desired it is possible to switch off the DHW during the night setback period. Your

installer can set this for you.

NOTE: This function is only available if your boiler is suitable for this

communication. Consult the user manual of the boiler or ask your installer.

CONTROLS LAYOUT

PROGRAMMING YOUR THERMOSTAT

Before you start programming

You can program your Chronotherm Modulation only if the mains supply of the

boiler is switched on, the electrical connection to the boiler is made and the

thermostat has been mounted on the wall plate. When the power for the

thermostat is present the display will be activated and the clock will start.

NOTE: Operate the keypad with your fingertips only. Sharp objects like pens or

pencils can damage the keypad.

How do I set the time and the day?

1. Move the slider to DAY/

position. The time and the

day marker will flash indicating that they can be

changed.

2. Press the + or – button until the correct time is

displayed. Each button press will change the time by

one minute and stop the display from flashing.

Holding the button down for a few seconds will

change the time slowly at first, then quickly.

3. Press DAY 1..7 button until the day marker is

positioned under the correct day (DAY1 is Monday).

Each button press moves the day marker by one

day.

How do I get started with the built-in temperature program?

Move the slider to the AUTOmatic position

The Chronotherm Modulation will now control your heating system using the built-

in temperature program.

You now have a choice of two methods to set the program for the next day

6.a Press the COPY DAY button to copy Monday’s program into Tuesday. To set

several days of the week to the same program, press the copy day button

repeatedly.

6.b Press the DAY 1..7 button to step the day marker to Tuesday (Day 2). The

program for Tuesday can be then set as described in steps 2 to 5.

Programs for Wednesday (Day 3) to Sunday (Day 7) can be set in the same

day, using the DAY 1..7 button.

7. Move the slider to AUTOmatic position when you have completed steps 6a or

6b. The Chronotherm Modulation will now control the room temperature to

match your program.

What do I do if I do not want to use all 6 temperature changes times?

The built-in program uses only 4 temperature change times as indicated in section

“How do I get started with the built-in temperature program?”

The unwanted change times can be deleted by moving the slider to PROGRAM

position and holding the appropriate button (1, 2, 3, 4, 5, 6) for a few seconds. The

change time will be removed and the display will show dashes instead of time/

temperature display.

Deleted temperature change times can be brought back by pressing the

appropriate (1, 2, 3, 4, 5, 6) button and then TEMPerature

or button (with

slider set to PROGRAM position).

OPERATING YOUR THERMOSTAT

With the operating mode slider in AUTOmatic position Chronotherm Modulation

will control the room temperature to match your heating program

Manual Override

When the slider is in AUTOmatic position the temperature can be adjusted

temporarily by pressing the TEMPerature

or button. The temperature will

return to program at the next temperature change time.

How do I set the temperature for the whole day?

To operate as a simple thermostat with one temperature throughout the day, move

the slider to the MANUAL position. Adjust the manual temperature by pressing

the TEMPerature

or button. The manual temperature can be set anywhere

from 5°C up to 30°C.

How can I switch the Chronotherm Modulation off?

Move the slider to the position. Thermostat has built-in frost protection feature,

so that if temperature will drop below 7°C it will automatically switch back on to

prevent pipes from freezing.

NOTE: The frost protection activation level can be adjusted from 7

C to 10

using TEMPerature

or button.

How do I check the programmed temperature?

In normal operation the temperature displayed is the actual room temperature. To

check the programmed temperature, press the i button once.

NOTE: During upward temperature level change the temperature on the display

may not correspond with the programmed level of the current period. The reason

is that during warm up the thermostat gradually increases the temperature level

setting to the next temperature change level. During the warm up period the

number of the next period is flashing

How can I check the outside temperature?

Press the

button twice. The outside temperature code T3 will be displayed

together with current outside temperature value.

NOTE: This option is available only if the heating appliance provides the outside

temperature information to the thermostat.

I am going on holiday for a couple of weeks. How do I save energy when I

am away?

1. Move the slider to the operating position you require on returning from your

holiday (AUTOmatic or MANUAL)

2. Press the

(HOLIDAY) button to display the holiday days counter and the

temperature

3. Press the

+ or – button to set the holiday time (1-99 days). An extra flashing

day marker shows the day of the week representing the holiday return day.

Today is counted as the first day of holiday. The holiday temperature is set

using the TEMPerature

or button. At midnight of the last day of your

holiday the thermostat will return to the normal control as set by the slider

position.

These two buttons can

also be used when the

flap is closed
