  • Page 13: Initialising The Modules

    INITIALISING THE MODULES Each module configured and present in the Clivet Talk control system must be recognised by the local network, which needs to know which device it is communicating with. A series of basic rules must be observed when configuring the system, so as to avoid incorrect settings.

  • Page 45: Operation Of The Temperature Controller

    OPERATION OF THE TEMPERATURE CONTROLLER COOLING The temperature controller acts by comparing the water outlet temperature to the system (average of the evaporator water outlet temperatures), against the current set point, and considering a number of threshold values. The temperature controller will tend to deactivate capacity-control steps when the water outlet temperature falls below the current set point Vice-versa, it will tend to activate capacity-control steps when the outlet temperature exceeds the sum of current set point + the theoretical value of the temperature difference between the water inlet and outlet due...

    FREECOOLING There are two different freecooling modes: INTERNAL: the freecooling coil is located near the condenser coil. During the freecooling phase, the condensing fans (managed by the compressor modules) are controlled according to the average evaporator outlet temperature, as shown below (that is, independently from the configuration of the system). OUT temperature CENTRAL MODULE Outside air probe...

  • Page 49 During the freecooling phase, the corresponding valve deviates the flow of water to the freecooling coil, located upstream of the evaporators. At the same time, the freecooling fans are activated according to the average evaporator outlet temperature. In this way, as the outside temperature is less than the return water temperature, the latter is cooled.

  • Page 52: Step Activation - Scan Times

    STEP ACTIVATION – SCAN TIMES The temperature controller can activate one and one only step at a time, and only at the expiry of the activation scan time. At all other times no steps may be activated. The activation scan time is not fixed, but rather varies according to the temperature difference between the water outlet temperature and the current set point.

  • Page 53: Set Point Correction In Cooling

    SET POINT CORRECTION IN COOLING The current set point in cooling is defined by the parameter SetCool and by the following corrections: • OutsideT correction: Value of the correction based on the outside temperature (between 0 and MaxCextC). If the outside humidity probe is present, the correction of the set point will also depend on the factor Enthalpy Ext correction (between 0 and MaxCextC).

    SET POINT CORRECTION IN HEATING The current set point in heating is defined by the parameter SetHeat and by the following corrections: • OutsideT correction: value of the correction based on the outside temperature (between 0 and MaxCextH). • WR correction: value of the Water Reset correction according to the external signal (between 0 and MaxCWRH).
