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’.
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.
