Enter the maxi- mum flow temperature of the heating circuit, which is reached by calculating with -1°C outside temperature at 20°C room temperature e.g., horizontal line at 82°C).
  • Page 83 Programming Fig. 15: Summer/winter heating limit Outside temp attenuated (Prog.no. 8703) SWHL SWHL Summer/winter heating limit Temperature Time 24-hour heating limit The 24-hour heating limit shuts off the heating circuit if the current outside tem- (732, 1032, 1332) perature increases up to the difference set here of the current operating level (re- duced or comfort set point).
  • Page 84 Programming Room influence The flow temperature is calculated using the heating curve as a factor of the out- (750, 1050, 1350) side temperature. This type of control assumes that the heating curve is set cor- rectly, since the control does not take any room temperature into consideration in this setting.
  • Page 85 Programming Boost heating The boost heating is active if the room set point is switched from protection (770, 1070, 1370) mode or reduced mode to comfort mode. During the boost heating the the room set point is increased to the value set here. This causes the actual room tempera- ture to increase to the new set point within a short period of time.
