03.00 hours).
The bar displays the day program set.

3 Radiator symbol for central heating operation.
•Symbolvisible=centralheatingoperationpossible.
•Symbolnotvisible=centralheatingoperationnotpos-

4 This symbol is visible when the boiler is set to the Economy
position and no central heating operation is possible. Room
temperature is now kept at approximately 5°C (anti-freeze
protection).
5 The hand symbol is visible when the room temperature of
the clock program has been adjusted using the arrow keys
(this applies until the next temperature change of the clock
program).
6 The sun symbol is visible if during a switched on weather
dependent setting the average daily temperature remains
above or around 18°C.
7 The fault symbol is visible as soon as a fault becomes ap-
parent.

1. Specications
This chapter explains how the clock thermostat
and some of its functions work.
• Nobatteries.
• Lossofvoltage
• Manualmode
• Centralheating’sclockprogram.
• Self-learningswitch-onoptimization:Comfortablywarmon

• AdditionalsavingsinEconomysetting.
• On-screendeviceinformation.
• Modulatingcentralheatingcontrol.
• Weatherdependentcontrol.
• Timerfunction.
No batteries
For its functioning the clock thermostat receives its energy
fromtheconnectedboiler.Nobatteriesrequired.
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(before12:00hours)willbedifferentthanintheafter-
noon(after12:00hours).Thisisbecausecoolingdownduring
the day is slower than at night. It may take about a week
before the thermostat ‘has learned how to work’.
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
quickhotwaterinput.Whenthepipeconnectionstothetap
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
TheWiZeclockthermostatcommunicateswiththeconnected
boilerviatheATAGZ-bus(OpenTherm),auniversalcommu-
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,theamesymbolindicateswhethertheboilerisonor
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
TheWiZeclockthermostatmeasurestheroomtemperature
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
TheWiZeclockthermostatcanalsobeusedasaweatherde-
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 taps 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
temperaturewillincreaseordecrease.Effectively:Thecolder
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
xedtemperature.Duringalongerabsence,forinstance,ital-
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.

2.1 Mounting
A .Choose a suitable location for mounting the thermostat.
Suitablemountinglocation:
At a height of approx. 1.5 m, away from windows and doors;
on an internal wall without obstacles around the room ther-
mostat.
Wrongmountingplaces:
•Inaplacewherethesuncannotshinedirectlyonthether-
mostat.
•Onacoldoutsidewall(maybettinginsulationmaterial

B. Remove the rear panel
C. Mount the rear panel on the wall (A refers)
Use the rear panel as a template to mark the holes! Seal the
hole where the wiring originates to prevent likely draught.
Use the screws and plugs supplied.
D. Fit wiring to rear panel
Make sure that the boiler plug has been removed from its
socket!
OnlyconnectthewiringtotheZ-ready/busthermostat
connectionoftheboiler.Wrongconnectionsmaycause
considerable damage to the thermostat! It does not matter
where the conductor is connected. Prevent the wires from
runningpast230Vcables.
E. Snap the housing onto the rear panel
(hold thermostat with both hands)
The thermostat hinges at the top and is clamped at the
bottom (in the middle).
