3. Appliance description

The appliance is a wall mounted electric direct heater for areas such as workspaces, kitchens, bathrooms and similar.

The quiet fan draws in the indoor air that is heated by a bare wire heater element. The air then exits evenly through the hot air channel and the air discharge grille set into the bottom of the appliance.

When the set room temperature is reached, it is maintained by periodic heating.

Overheating protection

The appliance is equipped with a high limit safety cut-out that switches the appliance off in case it overheats. Once the cause of the fault has been eliminated, the appliance restarts within a few minutes (cooling period).

I2	Relative heating time(The counter can be reset via parameter P5.)	[h]

Note

The counter for relative heating time (12) counts in complete hours how long the appliance heats for. When the appliance is switched off, any heating phase of less than 60 minutes is not recorded.

5.4.2 Time programs

Three time programs are available. Time programs Pro1 and Pro2 are pre-configured at the factory. Time program Pro3 can be set according to your individual requirements.

Display Description

Pro1	Time program "Daily"- Repeated: Monday to Sunday
Pro2	Time program "Weekdays"- Repeated: Monday to Friday
Pro3	Time program "User defined"- up to 14 comfort phases, freely configurable

Note

To use a time program, select the required time program from the standard menu (see chapter "Settings / Standard menu").

Note

Ensure the day of the week and the time are set correctly when setting the time programs.

Note

The following applies to all time programs (Pro1, Pro2, Pro3):

If the end time is later than 23:59 h, the end time will automatically be moved to the next day of the week. The comfort phase is maintained past midnight and will end on the next day at the set end time.

Time programs Pro1 and Pro2

You can specify the comfort mode start and end times with time programs Pro1 and Pro2. During this time period, the appliance heats to the set comfort temperature. Outside this specified time period, the appliance operates in setback mode. This results in a comfort phase and a setback phase, which are repeated daily (Pro1) or on every working day (Pro2).

Theses phases are factory-set as follows:

- 08:00 h - 22:00 h: Comfort mode

- 22:00 h - 08:00 h: Setback mode

Note

When time program Pro2 is enabled, the appliance operates at weekends exclusively in setback mode.

To adapt time programs Pro1 and Pro2 according to your needs, proceed as follows:

▶ In the configuration menu, use "+" and "-" to call up the required time program.

▶ Press "OK".

The start time for comfort mode is displayed.

▶ Use "+" and "-" to set the required start time.

▶ Press "OK".

The end time for comfort mode is displayed.

▶ Use "+" and "-" to set the required end time.

▶ Press "OK" to save.

Time program Pro3

To configure a comfort phase in time program Pro3, proceed as follows:

▶ In the configuration menu, use "+" and "-" to call up time program Pro3.

▶ Press "OK".

The display shows "3---".

▶ Press "OK".

A day of the week or a group of days is displayed.

▶ Use "+" and "-" to select the required day or group of days.

▶ Press "OK".

The start time for comfort mode is displayed.

▶ Use "+" and "-" to set the required start time.

▶ Press "OK".

The end time for comfort mode is displayed.

▶ Use "+" and "-" to set the required end time.

▶ Press "OK".

Comfort phase "3-01" has been configured.

▶ To configure a further comfort phase, use "+" and "-" in time program Pro3 to select display "3---". Proceed as describe above.

Note

To reset the selected comfort phases, activate parameter P4.

▶ Please note that activating parameter P4 resets all time programs (Pro1, Pro2, Pro3) to the factory setting.

5.4.3 Parameter

You can call up the following parameters:

Display Description Options
P1 Room temperature offset ± 3 °C | ± 5 °F
P2 Time format 12 h | 24 h
P3 Temperature display units °C | °F
P4 Reset the time programs (Pro1, Pro2, Pro3) on | off
P5	Reset relative heating time	on | off

To change the value of a parameter, use "+" and "-" to call up the relevant parameter. Press "OK".

As soon as the "Editable parameter" symbol appears, you can change the parameter value with "+" and "-". Press "OK" to save the selected value.

P1: Room temperature offset

Uneven temperature distribution in the room can result in a difference between displayed actual temperature l1 and the room temperature you measure. To compensate for this difference, a room temperature offset of ±3 ^ can be set via parameter P1.

Example: The appliance indicates I1 = 21.0 °C. You have measured a room temperature of 20.0 °C. There is a difference of 1.0 °C.

▶ To compensate for the difference, select an offset of P1 = -1.0.

P2: Time format

Parameter P2 allows you to specify whether the time is displayed in the 12 hour or 24 hour format.

P3: Temperature display units

Parameter P3 is used to specify whether the room temperature is displayed in degrees Centigrade [°C] or Fahrenheit [°F].

P4: Reset time programs

Activating parameter P4 resets all time programs (Pro1, Pro2, Pro3) to the factory setting.

P5: Reset relative heating time

Activating parameter P5 resets the counter for relative heating time (I2).

6. Cleaning, care and maintenance

7. Troubleshooting

Problem	Cause	Remedy
Room does not get warm enough. Ap- pliance does not get hot.	Temperature set too low on the appliance.	Check the temperature set on the appliance. Adjust if necessary.
	No power supply.	Check position of the ON/OFF switch, RCD and fuse/MCB in your fuse box.
Room does not get warm enough al- though the appliance is hot.	Overheating. High limit safety cut-out limits heating output.	Eliminate the cause (dirt or obstructions at the air intake or discharge). Observe mini-mum clearances.
	Heat demand of the room is higher than the appli- ance output.	Remedy heat losses (Close windows and doors. Avoid constant venting.)
The room gets too hot.	Appliance temperature is set too high.	Check the selected room temperature. Adjust if nec- essary.
Window open de- tection does not respond.	Appliance does not detect a pronounced tempera- ture drop when venting. (Window open detection requires a previously sta- ble room temperature.)	Wait a while after making settings on the appliance, until the room temperature has fully stabilised.
		Avoid obstructions to air changes between appliance and indoor air.
		Manually switch the appli- ance to standby mode for the duration of venting.
