Summary of Contents for Seltron ZCE6 Basic

  • Page 1 Zone heating / cooling controller ZCE6 Basic and ZCE6 Advance Instructions for use and setup...
  • Page 2 INTRODUCTION ZCE6 controllers have been designed for the control of zone heating and/or cooling. The control is carried out using thermal actuators on the distributor valves based on the temperatures obtained from room units. There are six independent temperature zones with the possibility of controlling fourteen heating-cooling units in total.
  • Page 3 APPEARANCE OF THE CONTROLLER 1-Connection terminals for controller power supply (230V~). 2-Connection terminals for circulation pump, energy source and mixing valve control. * 3-Connection terminals for the control of 24V~ thermal actuators.** 4-Selector switch for the control voltage of thermal actuators. ** 5-LED lights for the signalisation of operation.
  • Page 4 SIGNALISATION OF OPERATION Signalisation of temperature zone operation. When the LED light is on, the thermal actuators connected to the zone are in the open state, and vice versa. Signalisation of circulation pump output operation. When the LED light is on, the output is active. * Signalisation of energy source output operation.

  • Page 20: Description Of System Operation

    DESCRIPTION OF SYSTEM OPERATION Zone control (thermal actuators) Parameter C1.2 is used to select the type of thermal actuators connected to the controller. Type NC opens the thermal actuator when the output is under control voltage, type NO opens the thermal actuator when there is no control voltage at the output.
  • Page 21 Room units Up to 6 RCD room units can be connected to the controller. Wire and wireless room units can be connected. Wire units must connected to the connection termi- nals with label “room units” (1, 2, 3, 4, 5, 6), and for the operation of wireless room units, antenna must be connected to the terminal “ANTENNA”.
  • Page 22 Mixing valve (ZCE6 Advance) The mixing valve is controlled by closing and opening impulses (P-constant) in time periods (I-constant). When in heating mode, the measured temperature of supply line is below the desired temperature, the mixing valve opens, when the measured temperature is above the desired temperature, the mixing valve closes.
  • Page 23 Digital input “cooling” The digital input “cooling” enables a remote switchover of operation from cooling to heating. When a short circuit is detected on the digital input “cooling”, the control- ler switches over to the cooling mode. For the operation of digital input “cooling”, the parameter C1.6 must be set to value English 23...
  • Page 24 The input “dew point” enables the connection of digital or analogue dew point sensor. Parameter C1.7 is used to set the type of dew point sensor, which is connected to the input “dew point”. C1.7=0 - input is not used, C1.7=1 - digital sensor of type NC (short circuit when dew point is detected), C1.7=2 - digital sensor of type NO (open connection terminals when dew point is detected),...
  • Page 25 Output “10V” Parameter C1.15 is used to set the output “10V” operation mode: C1.15=1 - the voltage of 10V for sensor power supply is always available at the output, C1.15=2 - the 0-10V output signal is used to operate the source. Dependency graph of output voltage from desired temperature of supply line: Heating Cooling...

  • Page 26: Backup Operation

    Backup operation When the communication with the room unit is lost, the controller switches to back- up operation. Delayed switching to backup operation is set with parameter C7.1. In backup operation, the zone is switched on in a period set with parameter C7.2. The operating time (percentage of period) of a certain zone is set with parameters C7.3 (for zone 1) to C7.8 (for zone 6).
