Building Technologies Heat or cool per time switch program 2015-03-31
Heat or cool per time switch program
In room operating mode
, the controller operates
according to the selected heating program.
Time switch program
In the time s witch program, the start time and associated
room operating mode have been entered for all periods of
24-hour heating / cooling operation. The heating program
has been entered for you; if you wish, you c an change the
entries made (
Page 8) to satisfy your pers onal needs.
Example of a time program:
Tuesday
As of 12:30 Comf
As of 6:00 am Comfor t mode
As of 11:30 am Precomfort mode
As of 12:30 pm Comfor t mode
As of 7:00 pm Precomfort mode
As of 9:00 pm Economy mode
Do not heat or cool per time switch program
Select another room operating mode
If you do not
want to heat or cool according to the time
switch program (i.e., not automatically), you need to change
the preselection for the room operating mode.
Setpoints
The setpoints assigned to the room operating modes use
the same symbols and designations.
Setting setpoints is described on
page 7.
Symbol Room operating mode Comments
Comfor t Plant ON, H eating / Cooling on comfort
Precomfort Plant ON, H eating / Cooling on precomfort
Economy Plant OFF, Sustained mode Heating / Cooling on economy;

Protec tion Plant OFF, fr ost protection active
Path:
Welcome > Main menu > Room operating mode... > Preselection > ...
Do not forget to switch back to auto when you only intend to heat/cool temporarily!
Operate aggregates per time switch 2
When your controller is configured with a time switch, the
controlled aggregate (e.g. a pump) is switched on and off
per the set time switch program.
If also configured with [Time switch 2] op selector, it must be
set to auto, to automatic ally switch on and off the aggregate
per the set time switch program.
If a [time switch 2] op selector is available and you do not
want
to control the aggregate per the time switch program, you
can manually override it with the [time switch 2] op selector
eit her on or off.
Example of a time program:
Time switch 2
Saturday
Switched on at 6:00 am – switched off at 10:00 pm
Path:
Welcome > Main menu > [Time switch 2] op selector > Preselection:
If you want to s et the plant to On or Off for a limit ed period only, do not forget to return to auto in due time!

Room temperature
Your universal controller offers 4 room operating modes.
Each room operating mode are assigned two temperature
setpoints (heating and cooling).
Depending on the selected room operating mode, your
controller s witches the setpoints per a time program (
page 6) or controls continuously to the setpoint for the
selected room operating mode.
The following setpoints are available. The default factory
settings represent the recommended setpoints.
You can change the comfort and pr ecomfort s etpoints as

Change daily heating / cooling periods
General
In the time switch program, you can set the daily heating
and cooling periods to suit your individual needs.
Each day can accommodate a maximum of 6 switching
points; a room setpoint is assigned to each time period.
In addition to the weekdays (Mond ay through Su nday), you
can program a special d ay, that is, a special 24-hou r heating
and cooling program.
The special day is activated when you make an entry in
Holidays.
Changes on the controller are possible only if the controller's
time switch defines the program.
If an external operator st ation contr ols the program, changes
can only be made from that st ation.
Observe the following prior to making entries:
· First enter the start time for the heating/c ooling phase and
then the room operating mode f or the phase.
· The following room operating modes
, , and are
available. Set the corresponding setpoints in menu
Controller 1 and Controller 2 (
page 7).
· You can copy any 24-hour heating / cooling program to
other days.
Change and delete times and setpoints
1. Select the required day.
2. In the diagram, advance the pointer
to the time to be
changed.
3. Set the desired time.
Delete the time: Reset the time via 00:00 until ––:––
appears.
4. Select the desired operating mode.
5. If required, set additional times and select additional
setpoints.

The controller is supplied with a 24- hour program for every
day (including special days). This means that you will never
have to cr eate a new 24-hour program, but only change an
existing pr ogram.
Operating voltage off – heating / cooling program lost?
In the event of a power failure, the 24-hour programs
entered will be maintained, independent of the dur ation of
the power failure.
First, write down a 7-day schedule for daily switching times and operating modes – this will facilitate entry into the controller!

Save energy without sacrificing comfort
· During the day, do not allow the room temperature to
exceed 21 °C when heating. Each additional degree
increases heating costs by 6 to 7 %
· During the day, do not allow the room temperature to fall
below 24 °C when cooling. Each degree below that level
increases the cooling costs
· Guide values for the room temperatur e in living and
working spaces during heating and cooling periods:
– Daytime during heating period: Precomf ort = 19 °C,
Comfort = 20...22 °C.
– Daytime during the cooling period: Precomfort = 28 °C,
Comfort = 22...24 °C.
– Night time during the heating period: Economy =
14...18 °C. Pr otect objects sensitive to low
temperatures, such as plants!
– Night time during the cooling period: Economy =
29...31 °C.
· Ensure that there are no curtains, furniture or other objects
in front of or behind air inlets and outlets They have an
impact on air circulation and can caus e draf ts
· Closed shutters and blinds reduce heat loss
· Closing blinds in due time during the cooling season
reduces the impact of s olar radiation, thus saving cooling
costs
· Make sure air filters are checked and replaced at regular
intervals
If your plant uses a room unit with temperature and humidity
sensor, it s hould not be exposed to thermal and moistur e
disturbanc es since these affect the control function. For this
reason, th e following applies to the referenc e room where
the sensor is located:
· Avoid drafts through open doors
· Avoid heat gains from people, machines and lighting
· Ensure that there are no curtains, furniture or other
objects in front of temperature and humidity sens ors
Energy savings conserve our natural resources, thus contribut ing actively to environmental protection!
