Time of day/date

All data of the yearly time switch in your controller were entered when your plant was commissioned. If readjustments are required, use the Time of day / date menu.

Summer and wintertime

The same is true if you need to readjust the dates for the start of summer and wintertime.

Note: Do not enter the actual dates of changeover but, in accordance with international standards, the earliest possible dates for the start of summertime and winter-time!

The menu Time of day/date

The time of day (e.g. 09:53)
The date (e.g. July 25)
The year (e.g. 2007)
The start of daylight savings time (e.g. March 25)
The start of standard time (e.g. October 25)

Heat or cool per time switch program

In room operating mode controller operates according to the selected heating program.

Time switch program

In the time switch 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 can change the entries made (Page 14) to satisfy your personal needs.

Example of a time program:

As of 6:00 am Comfort mode

As of 11:30 am Precomfort mode

As of 12:30 pm Comfort 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 pages 12 and 13.

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 automatically 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 either on or off.

Example of a time program:

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 set the plant to On or Off for a limited 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 switches the setpoints per a time program (page 9) 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 precomfort setpoints as needed. The economy setpoint cannot be set at the user level.

Room humidity

If your plant also includes room humidity control, the universal controller allows you to change the humidity setpoint limits in comfort and precomfort room operating modes.

The following setpoints are available.

The default factory settings represent the recommended setpoints.

Your controller changes the setpoints according to a time switch program, or maintains the setpoint of the selected operating mode depending on the room operating mode.

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 (Monday through Sunday), you can program a special day, that is, a special 24-hour heating and cooling program. The special day is activated when you make an entry in Holidays ( page 16).

Changes on the controller are possible only if the controller's time switch defines the program. If an external operator station controls the program, changes can only be made from that station.

Observe the following prior to making entries:

• First enter the start time for the heating/cooling phase and then the room operating mode for the phase.
• The following room operating modes, and are available. Set the corresponding setpoints in menu Controller 1 and Controller 2 (page 12 und 13).
• You can copy any 24-hour heating / cooling program to other days ( page 15).

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.

Path: Welcome > Main menu > Time switch... > ...

Enter additional switching points

1. Select the desired day.
2. In the diagram, advance pointer to the last point in time of the current program.
3. Turn the OK knob by one notch; --- appears.
4. Set the desired start time.
5. Set the desired room operating mode.

Copy a 24-hour heating / cooling program

1. Select the day to be copied.
2. Turn the OK knob clockwise until Copy to: appears.
3. Press the OK knob.
4. The menu for the day selection (week sections, individual weekdays, special day) appears.
5. Select the desired weekday or week section.
6. Copy (press the OK knob).

Create a new 24-hour program

The controller is supplied with a 24-hour program for every day (including special days). This means that you will never have to create a new 24-hour program, but only change an existing program.

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 duration 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!

Holiday periods or special days

You can enter a total of 16 holiday periods and special days. During a holiday period, there is no heating / cooling program active, but only the same room operating mode. On special day(s), the special day program is active.

Date

Enter on the submenus Entry 1, Entry 2, Entry 3, etc., the holiday period or special day:

• Operating line start:
  Date, year and time of day for the start of holidays or special day.
• Operating line end:
  Date, year and time of day for the end of holidays or special day.
• Operating line reason: Holidays or special day

Every entry can be cancelled:
- Delete entry.

Room operating mode (for holidays).

Enter the desired room operating mode in the operating line room operating mode holidays.

The following choices are available:

Economy or
Protection

The entry will apply to all holiday periods.

Heating / cooling program (for special day)

Save energy without sacrificing comfort

During the day, do not allow the room temperature to exceed 21^ 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^ when cooling. Each degree below that level increases the cooling costs
- Guide values for the room temperature in living and working spaces during heating and cooling periods: - Daytime during heating period: Precomfort = 19 °C, Comfort = 20...22 °C.

Daytime during the cooling period: Precomfort = 28^ , Comfort = 22 24^

Night time during the heating period: Economy = 14...18 °C. Protect objects sensitive to low temperatures, such as plants!
Night time during the cooling period: Economy = 29 31^

• 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 cause drafts

• Closed shutters and blinds reduce heat loss
  Closing blinds in due time during the cooling season reduces the impact of solar 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 should not be exposed to thermal and moisture disturbances since these affect the control function. For this reason, the following applies to the reference 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 sensors

Energy savings conserve our natural resources, thus contributing actively to environmental protection!
