  • Page 37: Solar Optional Functions

    Solar optional functions If Free is selected, the function will run normally in the software but will not operate a relay. In the submenu Controller, all free relays of the controller are displayed. If external modules are con- nected and registered, their relays will be displayed in corresponding submenus.
  • Page 38 Bypass The Bypass function can be used to avoid an energy loss from the tank directly after loading has started. The still cold heat transfer medium in the pipework is diverted through a bypass past the tank. Once the pipe is warm enough, the tank can be loaded. The switch-on conditions can be adjusted individually.
  • Page 39 CS bypass The CS bypass function is a different possibility to activate the collector circuit. To enable the use of the CS bypass function, a CS10 irradiation sensor has to be connected. When the CS bypass function is activated, the irradia- tion value is the switch-on condition for the collector circuit.
  • Page 40 Solar external heat exchanger This function is used to link loading circuits that are separated by an external heat exchanger. The allocated relay is energized if one of the selected tanks is being loaded and there is a temperature dif- ference between the sensor of the corresponding tank and the solar fl ow.
  • Page 41 Evacuated tube collector function This function helps overcome the non-ideal sensor position with some evacuated tube collectors. This function operates within an adjusted time frame. It activates the collector circuit pump for an adjust- able runtime between adjustable pauses in order to compensate for the delayed temperature measure- ment.
  • Page 42 Target temperature When the Target temperature function is acti- vated, the pump speed control logic changes. The controller will remain at the minimum pump speed until the temperature at the allocated sensor exceeds the adjusted target temperature. Only then will the standard pump speed control start to operate.
  • Page 43 Backup heating suppression The Backup heating suppression blocks the con- ventional backup heating of a tank that is currently in solar loading. This function is activated if a previously selected Store is being loaded. Solar loading means that tank loading is only carried out for energy supply and not for cooling purposes etc.

  • Page 45 Drainback option A drainback system permits the heat transfer fl uid to drain back into the holding tank when solar energy is not collected.The drainback option will initiate the fi lling of the system when solar loading begins. Note: booster pump A drainback system requires additional com- ponents such as a holding tank.
  • Page 46 Twin pump The Twin pump function controls the equal distri- bution of pump runtime in systems with two equally usable pumps. If the allocated relay has exceeded its adjusted run- time and the next switch-on process is imminent, the reference relay is switched on instead. All characteris- relay reference relay tics are adopted.

  • Page 48 Flow rate monitoring The Flow rate monitoring function can be used to detect malfunctions that impede the fl ow rate and to switch off the corresponding relay. This will prevent system damage, e. g. through a dry run of the pump.

  • Page 51 Parallel relay The Parallel relay function can be used to operate an allocated parallel relay alongside a selected ref- erence relay. With this function, e. g. a valve can be controlled in parallel to the pump via a separate relay. If the Overrun option is activated, the parallel relay remains switched on for the adjusted overrun time after the reference relay has been switched off.
  • Page 52 Boiler loading The Boiler loading function can be used to load a tank zone between 2 sensors. For the monitoring of switch-on and switch-off conditions, 2 sensors are used. The switch-on and switch-off temperatures TBoiler on and TBoiler off are used as reference parameters.
