Appliance description

The appliance is a wall-mounted electric direct heater.
The appliance is suitable for use as a standalone heating system or can be used in spring and autumn and as a booster heater in smaller rooms.
The air inside the appliance is heated by a heating element and expelled via natural convection through the air discharge at the top. Cool indoor air is drawn in through the air intake on the underside of the appliance.
When the set room temperature is reached, it is maintained by periodic heating.

Operation

Programming unit
The appliance is operated using the programming unit which is located at the top right of the appliance front.

Use “+” and “–” to switch between the individual actual values, time programs, and parameters.
To exit the configuration menu, press “Menu”. The standard display appears.

Actual values
The following actual values can be called up:

Note
The counter for relative heating time (I2) counts in complete hours how long the appliance heats. When the appliance is switched off, any heating phase of fewer than 60 minutes is not recorded.

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.

– 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 is 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).

These phases are factory-set as follows:

• 08:00 h – 22:00 h: Comfort mode
• 22:00 h – 08:00 h: Setback mode

Note
When the 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
You can use the time program Pro3 to specify up to 14 separate comfort phases which are repeated weekly.
To configure a comfort phase in time program Pro3, proceed as follows:

• In the configuration menu, use “+” and “–” to call up the 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.

• 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 described 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.

Parameter
You can call up the following parameters:

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 the displayed actual temperature I1 and the room temperature you measure. To compensate for this difference, a room temperature offset of ±3 °C 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. ff 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).

Cleaning, care, and maintenance

The room gets too hot.| The appliance temperature is set too high.| Check the selected room temperature. Adjust if necessary.
The “Heating active” symbol flashes.  The appliance does not heat up.| The electronic room temperature controller restricts the duration between two start times to at least  10  minutes.
Heating remains off until this period has expired; the  “Heating active” symbol flashes.| Wait until the end of this period between two start
times.
WA115:A120indow open detection does not respond.| The appliance does not detect a pronounced temperature drop when venting.
(Window open detection requires a previously stable room temperature.)| Wait a while after making settings on the appliance, until the room temperature has fully stabilized.
Avoid obstructions to air changes between appliances and indoor air.
Install the appliance in direct proximity to a window.
Air the room by fully opening a window.
Manually switch the appliance to standby mode for the duration of venting.
The set room temperature is set lower than 15 °C.| Change the set room temperature to 15 °C or higher.
Window open detection not enabled.| Switch on window open detection in the standard menu.

Installation

Minimum clearances

Installing the wall mounting bracket
The appliance is intended for wall mounting using the wall mounting bracket supplied.
The appliance may only be installed horizontally.

Note

• The wall mounting bracket can be used as a template for wall mounting. This ensures sufficient clearance from the floor.

• Use a spirit level if the floor is uneven or sloping.
  

• Unhook the wall mounting bracket from the appliance.

• Place the centered wall mounting bracket horizontally on the floor. Mark holes 1 and 2.

• Lift up the wall mounting bracket so that its lower holes match up with the markings you have just made on the installation wall.

• Mark holes 3 and 4 on the installation wall.

• Drill the holes at the 4 markings.

• Secure the wall mounting bracket with suitable fixing materials (screws, rawl plugs). With the vertical slots, you can compensate for an offset fixing hole.

Appliance installation

Wall mounting bracket

• Hook the appliance onto the bottom tabs of the wall mounting bracket by the slots in the back of the appliance.

• Place the appliance in an upright position.

• Secure the appliance by pushing it towards the wall until it audibly snaps into place in the two upper springs on the wall mounting bracket.
  

• Secure the appliance against unintentional release using the supplied locking screw on the right or left-hand side of the wall mounting bracket.

Removing the appliance

• Undo and remove the locking screw from the wall mounting bracket.
• To release the appliance, push down the springs at the top of the wall mounting bracket.
• Tilt the appliance away from the wall and lift it off the bottom tabs on the wall mounting bracket.
