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. The large illuminated display ensures user-friendly operation. Installation can be achieved in 3 easy steps.
Step 1: Inserting (replace) the batteries
Remove the battery c • compartment cover.
New alkaline batteries have a life of approximately three years. A battery symbol (
Doing so will present a risk of explosion.
Do not throw the batteries into a fire.
Do not short-circuit batteries.
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.
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:
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.
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.
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 to 23:00 respectively) for every single day of the week:
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 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:
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:
Operating modes
To switch between the 3 operating modes described below, press the menu button briefly (these operating modes can only be selected following installation/Step 3)
Configuration menu
The configuration menu can be used to modify settings. To access this menu, press and hold down the menu button (for more than 3 seconds).
Use the setting wheel to select menu items and the OK button to confirm your choice. Press the menu button again to return to the previous level. After 65 seconds without anything happening, the menu will close automatically.
Display content during normal operation
During normal operation, the following are displayed: day of the week, time of day, date, operating mode, temperature setting, and switching periods. The bars indicate the weekly program’s switching periods are shown for every other time interval. For an example, please refer to “2. Weekly program: Examples”.
Setting the holiday function
If you want a fixed temperature to be maintained for a set period of time while you are on holiday or during a party, you can make use of the Holiday function. Press and release the menu button • repeatedly until the suitcase symbol (
The comfort/set-back temperature button (
Child-proof lock/Operating inhibit
The operation can be inhibited.
Setting the heating break
If the heating is being switched off for the summer, you can save battery power. This involves opening the valve up fully. Limescale protection measures remain in place.
Setting frost protection mode
If you do not want the room to be heated, the valve can be closed. It will only be opened again if there is a risk of freezing due to frost. Limescale protection measures remain in place.
Window open” function
In the event of a significant drop in temperature, the actuator can automatically detect whether the room is being ventilated. To save on heating costs, the temperature is then automatically reduced for a specific time period (factory setting: 15 minutes). While this function is active, the “window open” symbol (
Setting the offset temperature
The temperature is measured by the heating appliance itself, with the result that other parts of the room may be warmer or colder than this. To allow for this, you can set a temperature offset of ±3.5°C. If, for example, a temperature of 18°C is measured somewhere within the room instead of the 20°C set, it means that an offset of -2.0°C needs to be configured.
Restoring the factory settings
You can reset the actuator to its initial state manually. This will clear all the settings that have been made manually.
Intended use
The energy-saving controller has been designed for the purpose of controlling a standard heating appliance valve. The device may only be operated indoors and must be protected from the effects of dampness and dust, as well as solar radiation and sources of radiant heat. Using the device for a purpose or in a manner other than that described in this operating manual constitutes a breach of the “intended use” and shall invalidate the warranty and any liability claims. The same shall apply in the event of any conversion or modification work. The devices are intended exclusively for domestic use.
Error code on the display | Problem | Remedy |
Battery symbol ( | Battery power too low | Replace batteries |
F1 | Valve actuator sluggish | Check installation, inspect the heating valve |
F2 | Adjusting the range too large | Check actuator fastening |
F3 | Adjusting range too small | Check heating valve |
At 12:00 every Saturday, the actuator performs a weekly descaling function to prevent valve calcification.
Instructions for disposal
Do not dispose of the device with regular domestic waste. Electronic equipment must be disposed of at local collection points for waste electronic equipment in compliance with local directives governing waste
electrical and electronic equipment. The CE sign is a free trade sign addressed exclusively to the authorities and does not warrant any properties.
Safety instructions
The devices concerned are not intended for children and must not be used as toys. Do not leave packaging material lying around, as children might be tempted to play with it, which is extremely dangerous. Do not open the device: it does not contain any components that need to be serviced by the user. In the event of an error, please return the device to our service department.
