The corresponding circulation pump is switched on. Heating curve The basis of weather compensation; improves the matching of the heating output to the outside temperatures. If parallel cylinder charging is activated, the mixing circuits continue to be supplied during the cylinder heating procedure, i. This circulation pump is assigned to the cylinder charging circuit which has not been reconfigured.

The heating installation is controlled by the existing heating controller. The solar gain can be optimised in the operator level by means of the options described in the following. The night set back temperature can be set individually for each heating circuit.

Solar collector Solar collectors convert solar radiation into useful thermal energy for hot water supply and heating assistance. If the selected heating curve is too low, the desired temperature level may only be reached after a while or not reached at all.

Length of time the changed value remains effective in the control system If you have changed the target room temperature in the basic display, the new value takes effect in the control system. To ensure good heat transfer, the sensor is flat on one side. Secondary auro,atic If there is a large distance between the hot water source and the draw-off point e.

This is how a thermostat valve works: The second graphic display graphically represents the current solar gain. Print styles and identifiers Bold text denotes important information, proper names and identifiers parameters, menu names, operating modes, aruomatic Example: Different configurations are used depending on the version of the solar thermal energy system.

Off Solar pump kick Solar: They cannot all be displayed auromwtic a single screen. After an extended period without any operations, the display automatically reverts to the basic display.

The flow temperature in the heating circuit gets warmer the lower the outside temperature becomes. As a result, the solar gain is somewhat less. Combi storage tank Solar heating installations which provide both hot water and additional free heat for heating work with two cylinders: When the temperature in the solar collector is higher than that in the lower zone of the solar hot water storage tank by a defined amount, the auromativ pump switches on and the thermal energy is transferred to the drinking water in the cylinder.

The following notes are intended to guide you through the documentation. VR 10 standard sensor Fig. Target room temperature Room Temp. The heated water from the boiler flows into the heating circuit and returns to auromatuc boiler as cooled water.

The controller has the level of protection IP Exiting the Installer level The Installer level is automatically disabled after approx. Danger of slight personal injury Auromahic HK1 Timer programmes Mon-Fri 1 ——: The pump unit permanently monitors the energy provided by the collector array and switches the system off as soon as the energy exceeds the pump unit’s own requirements.


Selecting the menu An overview of all the menus can be found in Fig. Start-up — Make the basic settings on the central controller — Make the system-specific settings.

You can, for example, set the room temperature, time windows, set back temperatures and heating curves in the menus in the operator level. The Start time is marked. The heating curve is saved. In maximum output mode the controller automatically starts up the connected heating circuits.

As soon as the solar pump unit can no longer deliver the required level, or after 4 hours at the latest, the volume will be charged via the boilers. Therefore the value for the setting difference is automatically adjusted when 1 K is exceeded. HK2 temperature error The target temperature for heating circuit HK2 has not been reached after a defined time.

We accept no liability for a damage caused by failure to auromtaic these instructions.

The reheating takes place within the programmed timer programme, provided the target cylinder temperature has not been reached yet. HK1 temperature error The target temperature for the heating circuit has not been reached after a defined time.
