  • Page 48: Optimizer

    [Hours] Figure 4. The summer cut-off function Optimizer The purpose of the ECL 2000’s Optimizer function is to help run the plant in the most economic manner possible. The Optimizer offers functions for: • Calculating the optimum starting time in order for room temperature to reach the desired level (the comfort temperature) at the time defined in the 7-day plan.
  • Page 49 Service Settings Pre-heat period This is the function that allows the controller to calculate the optimum starting time. If the system is equipped with a room temperature sensor, this function is adaptive. If no room temperature sensor is connected, the controller estimates the room tem- perature as a function of the actual outdoor temperature and the default pre-heat pe- riod entered by the operator (see below).
  • Page 50 Service Settings Pre-heat method This function enables the controller to determine the flow temperature level during the pre-heat period. It is possible to: • Use the boost function, which increases the flow temperature by a user-defined percentage. The purpose is to reach comfort room temperature sooner, that is, re- duce the duration of the pre-heat period.

  • Page 51: Pump/Valve Settings

    When the Night stop parameter is set to ON, the ECL 2000 sends a STOP signal to the pump as soon as a night setback period starts, thus causing the pump to reduce its number of revolutions, re- gardless of other pump control criteria.
  • Page 52 Flow cut-off Depending on the type of ECL 2000 and the type of application you have selected, it is possible to customize 1 or more sensor inputs (see page 27). If one of these inputs is used to measure the water flow, the controller can be set up to close the valve if the flow in the system falls below a user-defined limit.
