Establishing radio connection

The radiator controller HR92 communicates with the central operating device by radio using the frequency of 868 MHz. To this purpose the connection between the HR92 and the central operating device has to be established first. This process is called BINDING. In the case of preconfigured devices binding has already been carried out in the factory Binding must first be activated at the HR92 so that the radio signal can be received. Subsequently, binding has to be activated at the central operating device

Activating binding at the HR92

• Press the button briefly. unbound is displayed.
• Hold the button pressed for 5 seconds. bind is displayed.
• Press the button briefly. binding is displayed and the radio symbol appears.

Activating binding at the central control device

Binding at the HR92
The radio symbol flashes during binding. If binding was successful, success is displayed. Afterwards the main display is shown. When sync is shown in the display, the radiator controller is synchronizing with the central operating device. HR92 receives the data from the central operating device.

Failed binding/insufficient data transfer
Binding has failed when the radio symbol disappears and failed is displayed. The data transfer output may be insufficient. This can be caused by metallic objects or further radio devices.

• Ensure that the distance to radio devices such as radio headphones, cordless phone, etc. amounts to at least 1 m.
• Ensure that the distance to metallic objects is sufficient.
• If radio interference cannot be eliminated, select a different mounting location for the room unit and repeat binding.

Basic settings

Overview

If required, the 12 basic settings (parameters) can be adjusted. Factory settings have a grey background. Parameters marked with an * are described in more detail below

Changing parameters

• Keep the button pressed for approximately 5 seconds until Parameter 1 flashes (left-hand digit).
• Use the adjustment dial to select the desired parameter (left-hand digit).
• Press the button to edit the parameter.
• The current setting of the parameter flashes (right hand digit).
• Use the adjustment dial to set the desired setting (right-hand digit) and confirm with
• The parameter being edited flashes (left-hand digit).
• For the further parameters repeat Steps 2 to 4.
• To exit the menu, select exit using the adjustment dial and confirm with the button.

Description of the parameters

Parameter 2 – Backlight

• The display has a backlight for reading the information.
• The backlight is ON when the adjustment dial is turned or a button is pressed.
• The backlight switches OFF if no action is carried out at the radiator controller for approx. 7 seconds in order to save battery power.

Parameters 3 to 5 – Window function
In order to save energy the radiator controller closes the radiator valve when you open a window resulting in a large drop of the temperature. When you close the window so that the temperature rises the radiator controller opens the radiator valve again. When the duration of the window function (factory setting: 30 minutes) has expired, the system controls to the current room setpoint temperature again. Frost protection is ensured during the window function.

Parameter 6 – Valve stroke
The radiator controller operates with the optimum valve stroke set in the factory. If the entire valve stroke is to be used or if the valve does not open completely, activate the full-stroke mode.

Parameter 7 – Temperature representation in the display

• In the factory setting the room setpoint temperature is displayed.
• With the setting “measured temperature” the measured room temperature is displayed. A changeover to the set temperature is carried out by turning the adjustment dial or pressing the button.
• If required, the temperature can now be reset. The display returns to the measured temperature after approx. 3 seconds.
• Due to the heat influence of the radiator the “measured temperature” displayed at the radiator controller can differ from the temperature measured at another point in the room.

Parameter 8 – Temperature offset
Since the radiator controller measures the room temperature in the area of the radiator, it is possible that this temperature deviates from the temperature measured at a different point in the room. If, for example, 20 °C is measured in the room and 21.0 °C at the radiator, this effect can be compensated by an offset of –1.0 °C.

Parameter 10 – Display of the valve position

• When this parameter is activated (setting “1”), the calculated valve position (0 … 100% opened) is displayed momentarily.
• The main display is shown again after approx. 3 minutes.
• To cancel, select exit and press the button.

Parameter 11 – Window open function

• If a window contact is connected, the parameter is set automatically to “2” (cabled). The window function is controlled by the window contact.
• If no window contact is connected, the setting “0” or “1” has to be selected.

Further functions

Manual changing of the room setpoint temperature
The room setpoint temperature can be changed at any time by means of the adjustment dial. The changed room setpoint temperature remains in effect until the next switching point.
The symbol shows that the temperature was changed manually. The symbol extinguishes when the next setpoint is reached. By turning the adjustment dial anti-clockwise until off is displayed, the valve will be closed permanently. With this setting the time program of the central operating device is no longer active for this radiator controller, but frost protection is guaranteed if the heating is switched on.

Display of the room name
If the central operating device can transmit the room name (zone name), like the evotouch, the room name is displayed at the radiator controller (max. of 9 characters).

• Press button.

The room name (zone name) is shown briefly in the display.

Automatic monitoring functions

Window function

• If you open a window causing the temperature to drop, the radiator controller closes the radiator valve in order to save energy. window is displayed.
• When the temperature rises again, but at the latest after the set period (factory setting: 30 minutes), the radiator controller opens the radiator valve again.
• You can also open the radiator valve beforehand by turning the adjustment dial.
• The sensitivity of the radiator controller to a temperature drop or temperature rise can be set, see Section 5, Parameters 3 to 5.
• If a window contact is connected, the window function reacts directly to the opening and closing of the window, see Parameter 11.

Valve protection
If the radiator valve has not been opened once completely within the period of 2 weeks, a self-test (forced operation) is carried out. The radiator controller opens the radiator valve briefly on the subsequent Monday in order to prevent seizing. cycl is displayed.

Frost protection
If the temperature drops below 5 °C, the radiator controller opens the radiator valve until the temperature rises above 6 °C again. This prevents the heating system from freezing up. frost is displayed.
