If a room is unused for a longer period of time, the Timer-Thermostat’s energy-
saving function will cool the room down to the Anti-Frost temperature (e.g. 5 °C).
If the room is being used again, it may take several hours before it is back to a
comfortable temperature. If you e.g. would like your guests to arrive in a warm
and cosy bungalow, ensure the heating is switched on well in advance. However,
the energy-saving function of the ICY Timer-Thermostat will reactive the Dormant
temperature after the Comfort period has elapsed, which means the bungalow will
only be heated until e.g. 15 °C. To ensure that in these situations the bungalow
is heated until e.g. 20 °C, the Comfort period should be temporarily extended. To
make this possible, ICY has developed WarmWelcome.
WarmWelcome will maintain the last set temperature until the Timer-Ther-
mostat is operated again.
This makes it possible - without changing any settings - to maintain a certain
temperature for a maximum of 2 days.
When your guests arrive, someone will, for whatever reason, touch the Timer-
Thermostat. WarmWelcome will automatically be deactivated and the Timer-Ther-
mostat will resume its normal cycle!
WarmWelcome will be activated by entering the last 2 digits of your PIN code.
After entering the code, the Timer-Thermostat will not give any indication whether
the PIN code was correct or incorrect. This means it is not noticeable if WarmWel-
come is activated or not! The only way to see this is when the Comfort period is
maintained. This means it is almost impossible for your guests to activate Warm-
Welcome, as after every attempt they have to wait for an entire Comfort period
to see whether it elapses – which indicates whether the PIN code entered was
correct or incorrect.
Activating WarmWelcome
Set the temperature to the setting you want WarmWelcome to maintain.
1.
Keep pressing the right-hand button until, after approx. 10s, the display
2.
reads ‘P2’.
Release the button. The display will now read ‘0’.
3.
The Timer-Thermostat is now in WarmWelcome mode and will request the
4.
last 2 digits of your PIN code.
Use the +(plus)-button and –(minus)-button to enter the correct number
5.
and wait approx. 10s after you’re finished.
If the PIN code is correct, WarmWelcome will be activated. If the PIN code
6.
is incorrect, WarmWelcome will not be activated. The Timer-Thermostat
will now leave the WarmWelcome mode.
Attention!
Activating WarmWelcome has to be the last change to the Timer-Thermostat! If
you touch the Timer-Thermostat again, WarmWelcome will be deactivated! The
functions of the ICY Timer-Thermostat are best explained by using a realistic
situation: e.g. a recreational bungalow.
How it used to be
With a conventional thermostat, we often see that users keep the heating on 20
or 22 °C day and night, even when they are away for a day to go cycling or swim-
ming. It is always better to come home to a warm bungalow or to wake up to a
cosy room. This is something they would not do at home, and which costs the
owner or manager of the accommodation a lot of money.
How it will be
By using an ICY Timer-Thermostat with presence detection, it is no longer pos-
sible to keep the thermostat set to such a high temperature. This results in a huge
reduction in energy use.
The Comfort period
With an ICY Timer-Thermostat, the user can set the desired temperature, by sim-
ply pressing the buttons on the thermostat. The maximum temperature can, how-
ever, be set by you (e.g. 24 °C).
This results in the first important saving!
After a certain period (the Comfort period), the Timer-Thermostat will beep, indi-
cating that the temperature will be lowered. You can decide how long the Comfort
period will last (e.g. 2 hours). (This does not apply to the ICY1810.) When the user
is present, the Timer-Thermostat can be reactivated to start a new Comfort period.
In the case of the ICY1845 and the ICY1850, the user does not need to reactive
the Timer-Thermostat. These two types detect the presence of users by means of
a motion detector and a key responder respectively.
The Dormant period
When no-one is present, the temperature will be reduced to the Dormant tempera-
ture set (e.g. 15 °C) as soon as the Comfort period elapses. The user will have to
press the Timer-Thermostat again to start a new Comfort period.
This results in the second important saving!
The Dormant temperature is maintained until the Dormant period has expired. You
can decide how long this Dormant period will last (e.g. 12 hours).
The Anti-Frost period
When the Dormant period has elapsed and no-one has reactivated the Timer-
Thermostat, this usually means the bungalow is no longer in use.
The Timer-Thermostat will now switch to the Anti-Frost temperature (e.g. 7 °C).
The Anti-Frost period will be maintained until the thermostat is used again. This
means it is impossible that an empty bungalow is being unnecessarily heated.
This results in the third important saving!
Saving energy
Results of tests and experiences from customers indicate that the reduction, de-
pending on the application, is between 20% and 55%!
Living comfort and the environment
The experiences of several bungalow parks have shown that with the right pro-
gramming, your guests will not experience any negative impact on their living
comfort.
The effect is mostly the opposite. Because people are becoming more and more
environmentally conscious, they experience this function as a positive contribution
to a reduction in energy wastage and as a contribution towards a better environ-
ment.
The patent
Because of their unique function, the ICY Timer-Thermostats cannot be compared
to other electrical thermostats. That is why our Timer-Thermostat is patented.
What are the applications?
Bungalow parks, holiday homes, hotels, congress centres, apartment complexes,
student housing, nursing homes, schools, office buildings, community centres,
sports facilities.
Why use a Timer-Thermostat?
High energy-saving, approx. 30%, because unnecessary heating is pre-
•
vented.
Very user friendly.
•
Highly reliable, as a result of the touch controls and absence of moving
•
parts and a relay.
Robust and stylish: solid, impact-proof cover and modern design.
•
Totally maintenance-free: no wear and tear to contact points and other mov-
•
ing parts.
No separate power supply or battery necessary, because of the advanced
•
electronics used.

The IN option
The IN option makes it possible to control and program the ICY Timer-Thermo-
stats remotely via radiotelegraphic communication! The IN option is available for
a surcharge, and offers you the opportunity to activate and alter all the functions
and settings from reception if using the ICY-Net.
