    If the set temperature at the DHW sensor is undershot and the BW charge is approved for the time, the DHW charge and the heat request will be turned on. The request only works if an energy source (burner, compressor, solid boiler) is activated as an additioanl function and if this source is set for the DHW request (see also Burner: Request BW on page 38, Compressor: request BW on page 40).

  • Page 21: Protective Functions

    6. Protective Functions The 'Protective functions‘ can be used by specialists to activate and set vari- ous protective functions. By no means does the controller replace the safety appliances on site! Seizing Protection If the anti-seizing protection is activated, the controller switches the heat pump and the mixer on/off at 12:00 noon for 5 seconds to prevent seizing of the pump/valve after long periods of inactivity.

  • Page 27: Function Overview

    Function overview Heating Circuit (X) S/W Day Summer / Winter changeover in daytime mode If this value is exceeded at the outdoor sensor the controller automatically switches the heating circuit off = Summer mode. If the outdoor temperature drops below this value, the heating circuit is switched on again = Winter mode. In addition to the operating times in normal daytime operation, this setting is also valid for times with activated comfort.

    Purging time If the temperature on the collector sensor increases within a minute by the value defined under “increase”, the solar circulation pump will be turned on for the set “purging time” so that the medium to be measured is transported to the collector sensor. If when the set ΔT is reached this does not switch on, a 5-minute circulation pause time for the starting aid function will apply.

  • Page 37: Solar Bypass

    Solar bypass Use a relay to switch a bypass valve or a bypass pump. With this function, the flow can be guided past the storage if the flow tem- perature at the bypass sensor is less than in the storage to be filled.

  • Page 40: Malfunctions/Maintenance

    Malfunctions/Maintenance Replacing the Fuse Repairs and maintenance may only be performed by a specialist. Before working on the unit, switch off the power sup- ply and secure it against being switched on again! Check that there is no power flowing! Only use the supplied spare fuse or a fuse of the same design with the following specifications: 2 AT/250 VSOREL Art.

  • Page 41: Additional Information

    Additional Information CAN bus The CAN bus can be used to connect two or more controllers with each other or with the data logger to exchange data. 1. The controllers are connected in series with the CAN bus cable. 2. The first and last controllers in this connection in series must be fitted with terminating resistance.

  • Page 42: Appendix

    Appendix Speed when „On“ In this menu, the calculation basis of the displayed speed is changed. If, for example, 30% is specified here, the fre- quency/voltage set under “PWM On” / “0-10V On” will be displayed during creation so that a 30% speed is present. When cre- ating the voltage/frequency of PWM Max / 0-10V Max, 100% speed is displayed.

  • Page 43: Tips

    Tips Tips Instead of setting the flow from the system with a volume flow limiter, the flow can be adjusted better through the stage switch on the pump and through the setting “max. speed” on the controller (see " Max. Speed " on page 23). This saves electrical energy! The service values include not only current measurement values and operating states, but also all of the settings for the controller.
