EASY PROGRAMMING IN THREE STEPS

Naturally you can use the factory setting of the thermostat which are set until you change

them (see Programming your thermostat – Factory Settings). However, it is quite simple

to adapt this program to your own desired week program.

Step 1: Program the right time and day of the week and select Summer- or Wintertime

(See: Programming your thermostat – Programming the right day, time and

Summer/Wintertime).

Step 2: Program your desired time-temperature settings for the week (see: Programming

your thermostat).

Step 3: Press START PROGRAM to acknowledge and activate the new program.

BEFORE USING YOUR THERMOSTAT

The Chronotherm IV has a number of characteristics that distinguishes this thermostat

from other programmable thermostats. By learning more about these characteristics you

can optimalize the possibilities which the Chronotherm IV offers.

Adaptive Intelligent Recovery

The Chronotherm IV makes sure that, on the time you have programmed, the desired

temperature has been reached. The thermostat does this by daily calculating and

monitoring the time it needs to warm up the room.

Using this information, the thermostat calculates at what time it’s supposed to start

warming up the next day. When programming, you just punch in the time on which you

want the new temperature realized.

The time at which the thermostat starts to warm up is different every time. During a cold

period the thermostat starts to warm up earlier than in Spring or Autumn. So it is not

necessary to change the warming-times yourself as the seasons turn. As soon as the

thermostat is installed, it starts its daily correction process of its Adaptive Intelligent

Recovery. After a few days the thermostat has calculated the right time for heating up.

Intelligent Heating

Your body perceives temperature from a variety of sources, not only from the air in the

room, but also from your surroundings – walls, windows and furniture. Common

thermostats sense only air temperature, which may or may not reflect how hot or cold the

room actually feels to a person. The Chronotherm IV reads the temperature of the wall as

well of the air – and responds to temperature changes as little as half a degree Celcius –

so room temperature is more likely to “feel right”.

In the morning, heating up is being done very gradually. Not only does this diminish the

risk of “overshoot”, meaning that the heating up exceeds the desired temperature. Also

the gradual heating up means less strain on the pipes in your home.

Programming Options

You can program at least four temperature-changes (periods) per day. These periods are

called RISING, LEAVING, COMING HOME AND SLEEP. To activate the periods you

program the beginning time and the desired temperature, if necessary for each day in a

different way. If four periods per day are not sufficient, you can easily extend the number

of periods per day to six with the periods LEAVING 2 and COMING HOME 2. This

allows you to program a raise in temperature if you come home around lunch.

Extra programming options

•Using COPY DAY you can quickly and easily program the other days of the week.

•The thermostat has a unique holiday/timer function which can hold a temperature for

a time until a certain moment. You can use this function for a holiday, for a weekend

away from home or even for a few hours using the timer.

•By touching only one button you can change today’s and/or tomorrow’s program into

Sunday’s program.

Flame symbol

As soon as the thermostat switches on the heater, the Chronotherm IV display shows a

flame symbol in the lower left side of the screen. This allows you to ascertain at any time

if your heater is being active.

Batteries

Before using the Chronotherm IV you need to place 3 ‘penlight’ alkaline batteries (type

AA). The average lifespan of batteries in the Chronotherm IV is at least two years (see

also: Replacing the batteries). As soon as the batteries are in place, the Chronotherm IV

will function according to the factory setings of the period RISING of Monday.

Manual control right after installation

After the batteries have been placed you can, if you don’t program the thermostat right

away, control the Chronotherm IV manually first.

You activate manual control by pressing Arrow Up (red: warmer) or Arrow Down (blue:

colder) to request the desired temperature.

You can do the same by pressing Temperatuur Continu. The abbreviation “Cont” is being

displayed, and with Up and Down you can select the desired temperature.

Pressing Start Programma ends this function.

Lighted display

Every time you press a button the display lights up for a few seconds. So even at night the

indications on the display are easy to read.

Memory Chip

The Chronotherm IV is equipped with a memory chip that keeps all adjustments. Even if

the batteries are empty the program is remembered. In that case, you’ll only have to punch

in the right time.

Temporary adjustments are not being saved.

OPTIONAL ADDITIONAL FUNCTIONS

Your Chronotherm IV is prepared for the following additional functions:

1. Reading outside temperature:

Needed: outside temperature reader (C7089B1000), wall plate* for Chronotherm IV

(Q8602A2001)

2. Switching on or off the thermostat to a preprogrammed temperature (tele-function):

Needed: an extern switchboard, used for telephones or computers (not a Honeywell-

product), wall plate* for Chronotherm IV (Q8602A2001).

3. Optimal Comfort for manual, temporary change over to outdoor temperature control

(OTC), intelligently linked to Chronotherm IV’s program.

Needed: Set Y 1019A2003 existing of:

-Smart Switch outdoor temperature controller;

-Outside temperature reader;

-Supply water temperature reader;

-Wall plate with push-button**

* Multifunctional wall plate is both suited for functions 1 and 2.

** Wall plate is also suited for installing an extra reader (C7089B1000) for reading

outside temperature and switchboard for tele-function.

N.B.: All additional functions of the Chronotherm IV are being activated using the

installers-program. Ask your installer about optional applications in your heating

installation or call Honeywell Infolijn (see last page).

1. PROGRAMMING YOUR THERMOSTAT

You can program your Chronotherm IV either mounted on the wall plate or holding it in

your hand. The first step to make your thermostat ready for use is to program the right day

of the week, the time and the selection of Summer- or Wintertime. After this, you can

either make the device run according to the pre-programmed factory settings or you can

program your own settings. Before programming your own settings, you have to decide

whether you want to use 4 or six different periods per day. To make it easier on yourself,

it helps to write down your settings before programming.

BEWARE: only press the buttons with the tip of your finger. Sharp objects such as a

pencil may damage the buttons!

Programming the right day, time and Summer- or Wintertime

1. Press “Invoer dag/tijd”.

In the display the indications TIME, ZO or WI appear, MA and the time.

2. Press button “Day” so often till you see in the bottom of the display the abbreviation

for the right day.

3. Press buttons “Up” and “Down” (right of the display) to select the right hour.

Press buttons “Vooruit” and “Terug” to select the right minutes for the time.

Press “I” (right of the display) to set the seconds on “00”.

Selecting Summer- or Wintertime

In the left top corner of the display Summer- or Wintertime is indicated.

Press, if necessary, “Zomertijd/Wintertijd” to select the right season.

Acknowledging the new settings

Press “Start Programma” once. Settings for day and time are now activated. In the
