1. Specications

This chapter explains how the clock thermostat

and some of its functions work.

• Nobatteries.

• Lossofvoltage

• Manualmode

• Centralheating’sclockprogram.

• Self-learningswitch-onoptimization:Comfortablywarmon

time.

• AdditionalsavingsinEconomysetting.

• On-screendeviceinformation.

• Modulatingcentralheatingcontrol.

• Weatherdependentcontrol.

• Timerfunction.

No batteries

For its functioning the clock thermostat receives its energy

fromtheconnectedboiler.Nobatteriesrequired.

Loss of voltage

In the case of loss of voltage all settings are saved in the clock

thermostat’s memory. After a 4 hour loss of voltage only the

day and time setting has to be reset. However, for it to work the

clock thermostat should have been connected for a minimum

of 1 hour. To save energy during loss of voltage no information

is being displayed on the screen.

Operational mode selection:

a. Manual mode

The clock thermostat can be used as an ‘ordinary’ room ther-

mostat, i.e. without using the clock program. In this case you

can switch on the thermostat in the morning, adjust it during

the day as required and reset it to the night temperature in the

evening.

Refer to chapter 3 for additional information.

b. Automatic mode

(Clock program for central heating)

The thermostat has a clock program which automatically con-

trols room temperature every day of the week. Every day and

every half an hour a different temperature can be preset.

Refer to chapter 4 for additional information.

Self-learning: Comfortably warm on time

(only in automatic mode)

The self-learning switch-on optimization ensures that the re-

quired temperature is reached at the time programmed. Since

outside temperatures vary daily, the thermostat re-determines

every day at what time the boiler has to start up in the morning

to ensure it being warm on time. If that temperature has not

been reached at the time set, it will start heating up earlier the

next morning. The same applies the other way round. This

switch on optimization also applies when the thermostat setting

is lowered during the day and the home is heated up again in

the afternoon. In this case, the switch-on optimization in the

morning(before12:00hours)willbedifferentthanintheafter-

noon(after12:00hours).Thisisbecausecoolingdownduring

the day is slower than at night. It may take about a week

before the thermostat ‘has learned how to work’.

ThisfunctionisfactorysettoOFF.Whendesiredyourinstaller

can change this setting for you.

Additional savings in Economy setting

(Does not apply to ATAG Q-Series)

Using the thermostat it is possible to switch any available Com-

fort settings for hot water mode on or off. In the Comfort setting

the boiler’s hot water input is set to retain its temperature for

quickhotwaterinput.Whenthepipeconnectionstothetap

are short, at night or when you are away, this Comfort setting

is not required and you can switch the boiler setting back to

Economy. There are 4 alternatives for Comfort and Economy

settings.

Additional information can be found in chapter 5.2.

Communication language

TheWiZeclockthermostatcommunicateswiththeconnected

boilerviatheATAGZ-bus(OpenTherm),auniversalcommu-

nication language for boilers. By means of a double core cable

this language is used to exchange information between the

thermostat and connected boiler.

On-screen device information

Using the thermostat certain boiler data can be read. For

instance,theamesymbolindicateswhethertheboilerisonor

not. The information menu, amongst other things, can display

the outside temperature or boiler pressure. It depends on the

boiler type whether all menu information is displayed because

related sensors have to be available and installed.

Refer to chapter 5.4 for additional information.

Modulating central heating control

TheWiZeclockthermostatmeasurestheroomtemperature

and uses it to determine the area’s heat demand. Depending

on room temperature the thermostat determines the water

temperature required by the boiler. As a result the boiler also

determines the capacity required resulting in optimum heat

input to the house combined with the lowest energy consump-

tion possible.

Weather dependent control

TheWiZeclockthermostatcanalsobeusedasaweatherde-

pendent control. The major difference as opposed to ordinary

room temperature control is that when the weather dependent

control is switched on the boiler input temperature is being

controlled instead of the temperature of the room where the

thermostat is located. The control is called ‘weather dependent’

because it uses an optional outside temperature sensor. In

combination with thermostatic radiator valves throughout the

house, room temperatures for each room can be controlled

individually. Depending on measured outside temperatures

and the heating curve set on the thermostat, the boiler’s water

temperaturewillincreaseordecrease.Effectively:Thecolder

it gets outside, the hotter the boiler’s water will get and vice

versa.

Refer to chapter 5.8 for additional information.

Timer function

Using the timer function you can select either a set time or a

xedtemperature.Duringalongerabsence,forinstance,ital-

lows you to temporarily select a lower temperature or a higher

temperature for a party or when you are doing overtime.

Refer to chapter 5.3 for additional information.

5.8 User recommendations / holidays

Keep radiators placed in the area with the room thermostat

always open.

The actual temperature and room temperature measured by

the thermostat may differ slightly depending on the installation

and position of the room thermostat . This may be the case, for

instance, when the thermostat is mounted on an outside wall.

Consult your installer for further information.

Night temperature setting

It is recommended not to set the night temperature more than

5°C below the day temperature. For installations with just

oorheatingitshouldnotbesetlowerthan2°Conaccountof

havingtoretheboilerfollowingthelowernightsetting.

totemporarilysetaxedlowtemperature,youcansetthe

thermostat to manual mode. Chapters 3.1 and 4.1 provide ad-

ditional explanations in this respect.

Weather dependent control

Usually the weather dependent control is active when an out-

doorsensorhasbeentted.Youmaycheckthisbyreferringto

chapter 5.4 or checking whether the outside temperature (no.1)

isdisplayed.Whenyouseeanoutsidetemperaturedisplayed,

required room temperatures but a shift on the heating curve.

Whenthesettemperatureishigherthan20°C,thenthe

central heating’s water temperature will get higher than the

onesetbytheinstaller.Whenthesettingislowerthan20°,

the central heating’s temperature will also decrease (for in-

stance at night). Consequently, using the settings T1, T2 and

T3 you can either increase or decrease the central heating’s

temperature.

-T<20°C:thecentralheating’swatertemperatureisgetting

•Ifyouwantatemperaturethatistemporarilyhigherorlower

ase or decrease it temporarily. Chapter 4.5 refers.

Consult your installer for further information.

Prevent freezing of your central heating installation

WhenthethermostathasbeenswitchedoffforboththeCom-

fort setting and the central heating (the (!) symbol is visible),

the thermostat will keep room temperature at a minimum of

5°C(Frostprevention).Thisisthecasewhen‘UIT’(OFF)has

been selected in the central heating menu and the tapwater

menu. However, it is advisable not to set the thermostat lower

than approx. 12°C. This reduces the risk that parts of your cen-

tral heating system or water pipes will freeze considerably, in

particular when the pipes are located in a frost-exposed area.

6 Trouble-shooter

This chapter explains some faults and questi-

ons you may have regarding the functioning of

the thermostat.

Questions / complaints about your heating installation

Explanations are given in respect of likely questions.

Faults

Explanations are also given in respect of faults usually indica-

ted by the

symbol. Check whether you can solve the faults

yourself and call your installer if necessary. These faults may

also be caused by a connected boiler. Therefore, also check

the boiler’s display screen and refer to the corresponding

manual.

Questions / complaints about your

The boiler comes on earlier than the time set on the cen-

tral heating’s clock program.

• Thethermostatwillwanttoreachtherequiredtemperature

at the time set. As a result the boiler will start heating up ear-

lier, this is the so-called self-learning switch-on optimization

(chapter 1 refers).

The boiler’s starting time may be different every day, be-

cause the moment the thermostat has to come on to reach

the required temperature on

time is being recalculated every

day. This is a normal situation.
