The temperature controller regulates the status of up to two components based on one or two temperature differences. The controller may be used for different components including the switching valve (see chapter Mixing valve controller<\/a>)<\/p>\n\n\n\n

The controller has 1 (plus 3 optional) analogic inputs.<\/p>\n\n\n\n

The controller has 1 (plus 1 optional) digital outputs.<\/p>\n\n\n\n

The switch cuts-in or off based on the comparison of two or four different temperatures. The comparison may be carried out with a constant value; if several temperature sensors are used the different measured temperatures will be compared with one another.<\/p>\n\n\n\n

With this setting the swimming-pool pump is activated only if the temperature measured by Temperature sensor 1 (Collector: outflow temperature) is higher than the temperature measured by Temperature sensor 2 (Pool: temperature) AND the temperature measured by Temperature sensor 3 (Tank: Layer 4) is higher than the reference for Temperature sensor 3: Fixed value = 70\u00b0C. As the swimming-pool is only used from May through to September the timer will be set accordingly.<\/p>\n\n\n\n

Input Values<\/strong><\/h2>\n\n\n\n

<\/p>\n\n\n\n

Temperature Sensor 1 [\u00b0C]<\/h3>\n\n\n\n

The value refers to the point where the temperature should be measured. Enter a component from the list.<\/p>\n\n\n\n

Temperature Sensor 2 [\u00b0C] (Optional)<\/h3>\n\n\n\n

The value refers to the point where the reference temperature for temperature sensor 1 should be measured. Enter a component from the list.<\/p>\n\n\n\n

Temperature Sensor 3 [\u00b0C] (Optional)<\/h3>\n\n\n\n

In case of  AND \/ OR operation an additional switching conditions may be defined. Analogous to Temperature sensor 1.<\/p>\n\n\n\n

Temperature Sensor 4 [\u00b0C] (Optional)<\/h3>\n\n\n\n

The value refers to the point where the reference temperature for temperature sensor 3 should be measured. Enter a component from the list.<\/p>\n\n\n\n

Description of Control-Parameters<\/strong><\/h2>\n\n\n\n

<\/p>\n\n\n\n

Description<\/h3>\n\n\n\n

The \u201cdescription\u201d value enables the user to assign controllers any name of number. Polysun assigns a consecutive number as a standard feature as different controllers are added chronologically in the hydraulic system<\/p>\n\n\n\n

Sign of the Output<\/h3>\n\n\n\n

The term \u201cNormal\u201c means that digital output signals are controlled as intended in the switching logics. (Example: if X1>Fixed value or if X1>X2 the output Status Switch 1 is positive). The term \u201cInverted\u201d means that the digital output signals are multiplied by -1. (Example: if X1>X2 the output Switch 1 is equal to zero). In case of inverted selection hysteresis may not be used.<\/strong><\/p>\n\n\n\n

Logical Connection Temperature Sensor 1 and 3<\/h3>\n\n\n\n
    \n
  • None
    The output is activated based on the requirements existing amongst \u201cTemperature sensor 1, Reference temperature, Temperature sensor 2 or Fixed temperature setting 1\u201c.<\/li>\n\n\n\n
  • AND-Operation
    The requirements existing between \u201cTemperature sensor 1, 2, Fixed temperature setting 1\u201c, AND <\/strong>\u201cTemperature sensor 3, 4, Fixed temperature setting 2\u201c must be met.<\/li>\n\n\n\n
  • OR-Operation
    The requirements existing between \u201cTemperature sensor 1, 2, Fixed temperature setting 1\u201c, OR <\/strong>\u201cTemperature sensor 3, 4, Fixed temperature setting 2\u201c must be met.<\/li>\n<\/ul>\n\n\n\n

    Definition of Temperature Setting<\/h3>\n\n\n\n
      \n
    • Fixed value
      If the temperature measured by Temperature sensor 1 or 3 drops below the specified Fixed temperature setting 1 or 2, the controller output switches to \u201con\u201d.<\/li>\n\n\n\n
    • Variable value
      If the temperature measured by Temperature sensor 1 or 3 exceeds the temperature measured by Temperature sensor 2 or 4, the controller output switches to \u201don\u201c.<\/li>\n<\/ul>\n\n\n\n

      Use of Hysteresis<\/h3>\n\n\n\n

      If hysteresis is used the following applies<\/p>\n\n\n\n

        \n
      • Cut-in hysteresis [K]
        If the temperature measured by Temperature sensor 1 or 3 exceeds the reference temperature by the specified temperature hysteresis, the controller output switches to \u201don\u201c.<\/li>\n\n\n\n
      • Cut-off hysteresis [K]
        If the temperature measured by Temperature sensor 1 or 3 drops below the reference value by the specified temperature hysteresis, the controller output switches to \u201doff\u201c.<\/li>\n<\/ul>\n\n\n\n

        Output Values<\/strong><\/h2>\n\n\n\n

        <\/p>\n\n\n\n

        Status Switch 1<\/h3>\n\n\n\n

        This digital output refers to the component to be controlled within the system. Select the relevant component from the list.<\/p>\n\n\n\n

        Status Switch 2 (Optional)<\/h3>\n\n\n\n

        This digital output is activated just like the Status Switch 1 output. Select the relevant component from the list.<\/p>\n\n\n\n
