  • Page 36 EQJW145: Heating controller Commissioning Optimisation SP53 When the optimisation function (SP53 = 1) is enabled, it has the effect that the selected room temperature is actually reached in normal mode at the point in time that was set in the switching programme. The usage times should therefore be set as they are actually needed.
  • Page 37 EQJW145: Heating controller Commissioning When the optimisation function is switched off (SP53 = 0), the heating is also switched off initially on changing from normal to reduced mode if the room temperature is at least 2.5 K higher than the setpoint for reduced mode. Not until the room temperature has fallen back to the setpoint does the heating mode start again in accordance with the heating characteristic.
