General function

This energy-saving controller for radiators can be used to control room temperature on the basis of time. The actuator moves a valve, thereby allowing the amount of heat flowing to the heating appliance to be controlled. The controller is compatible with all standard heating appliance valves.
Installation can be achieved in 3 easy steps.

Step 1: Inserting (replace) the batteries
- Remove the battery compartment cover.
- Insert 2 new LR6 batteries (Mignon / AA) into the battery compartment, ensuring they are the right way around.
- Reattach the battery compartment cover and click it into place.
- New alkaline batteries have a life of approximately 3 years.
  A battery symbol ( ) will indicate when the batteries need to be replaced. After removing the old batteries, please wait approximately 1 minute before inserting the new ones. This device does not support operation with rechargeable batteries.
  Never recharge standard batteries.
  Doing so will present a risk of explosion.
  Do not throw the batteries into a fire.
  Do not short-circuit batteries.
  Used batteries should not be disposed of with regular domestic waste. Instead, they should be taken to your local battery disposal point.
Step 2: Setting the date and time of day
The firmware version number will be displayed briefly once you have inserted/replaced the batteries and then you will be automatically prompted to set the date and time of day.
- Use the setting wheel (B) to set the year (A).
- Confirm with OK (C).
- Use the setting wheel (B) to set the month (A).
- Confirm with OK (C).
- Use the setting wheel (B) to set the day (A).
- Confirm with OK (C).
- Use the setting wheel (B) to set the hour (A).
- Confirm with OK (C).
- Use the setting wheel (B) to set the minute (A).
- Confirm with OK (C).
  The motor will start moving back the control pin while the entries are still being made.
- If “INS” is displayed with a rotating “Π” symbol, this indicates that the motor is still moving back. Once the device is ready for the actuator to be installed on the valve, just “INS” will appear on the display.
- The weekly program and other settings can be customized prior to installation. To do this, press the menu button when “INS” is shown on the display. For further details, please see “4. Configuration menu”.
- Once programming is complete, “INS” will reappear on the display, and installation (Step 3) can commence.
Step 3: Installing the energy-saving controller
The actuator can be installed on all standard heating valves. There is no need to drain away water or fiddle around with the heating system before doing this. First, you need to remove the old thermostat dial:
- Turn the thermostat dial anticlockwise as far as it will go (A).
- Release the thermal ring of the thermostat (B).
- Remove the thermostat from valve (C).
  An adapter will need to be used in the case of certain valves.
  Adapters for Danfoss valves (RA, RAV, RAVL) are included in the scope of delivery. For details, please refer to the adapter overview (see 18).
- The adapter must be placed on the valve and turned until it is securely seated.
- In the case of the RAV adapter, the extension supplied must be attached to the valve tappet.
- The RA and RAV adapters must, in addition, be secured by means of the bolt and nut supplied.
  The energy-saving controller can only be installed if “INS” is showing on the display. Following installation, the actuator will perform an adjustment run so that it can adapt to the valve. During this process, “ADA” will be displayed.
- Place the actuator on the valve.
- Tighten the union nut.
- “INS” will appear on the display, press the OK button.
- The actuator will perform an adjustment run (“ADA” will appear on the display, operation not possible).
- After that, the actuator will be ready for operation (Auto mode).
  If the adjustment run was initiated prior to installation, or if an error message will be displayed (F1, F2, F3); press OK to move the motor back to the “INS” position.

Setting the weekly program

The weekly program allows you to set up to 3 separate heating periods (7 switching times) for each day of the week. Programming is performed in relation to the selected days, for which temperatures must be stored for a period from 00:00 to 23:59.
Press and hold down the menu button for more than 3 seconds.

“PRO” will appear on the display.
Confirm with OK.
“DAY” will appear on the display. The setting wheel can be used to select an individual day of the week, all working days, the weekend or the entire week (the example shows the working days selected).
Confirm with OK.
The first setting time will appear on the display (0:00). This cannot be changed. In addition, the display shows bars for every other switching interval.
Confirm with OK.
Set the temperature that is to be maintained from 0:00 onwards (example shows 17.0°C).
Confirm with OK.
The next switching time appears on the display (the example shows 6:00).
Use the setting wheel to set the time.
Confirm with OK.
Then, select a temperature for the selected switching time.
Keep repeating this process until you have finished storing temperatures for the period from 0:00 to 23:59.
After all 7 switching times have been selected, 23:59 will appear on the display as the end time.
Confirm with OK.
In Auto mode, the temperature can be modified at any time via the setting wheel. The modified temperature will then be retained until the next program changeover.

Weekly program: Examples

The energy-saving controller allows you to store up to 3 heating periods (7 switching times) with individual temperature settings for each day of the week. The factory setting consists of two heating phases (from 6:00 until 9:00 and from 17:00 until 23:00 respectively) for every single day of the week:

From 00:00 to 06:00 17.0°C
From 06:00 to 09:00 21.0°C
From 09:00 to 17:00 17.0°C
From 17:00 to 23:00 21.0°C
From 23:00 to 23:59 17.0°C

To represent the switching periods, the display shows bars for every other switching interval. In this example, no bars are shown for the interval from 0:00 to 6:00. Bars are only shown on the display for the intervals from 6:00 to 9:00 and from 17:00 to 23:00.
If a room also needs to be heated at around noon, the corresponding program might look like this:
Monday to Sunday

From 00:00 to 06:00 16.0°C
From 06:00 to 09:00 22.0°C
From 09:00 to 12:00 17.0°C
From 12:00 to 14:00 20.0°C
From 14:00 to 17:30 17.0°C
From 17:30 to 23:30 21.0°C
From 23:30 to 23:59 16.0°C

If you have a home office and only want it to be heated during the day on working days, you can program the following times:
Monday to Friday

From 00:00 to 08:30 17.0°C
From 08:30 to 17:00 21.0°C
From 17:00 to 23:59 17.0°C
Saturday and Sunday
From 00:00 to 23:59 15.0°C
