  • Zoning board


    APPLICATION
    The microcontroller devices of the ZMEK family have been designed to be interfaced with the boiler board. They can control systems structured as follows:
    • up to three zones at high temperature
    • one zone at high and one at low temperature (with 3-way modulating valve)
    • systems having 2 low temperature zones (with 3-way modulating valve)
    Cascade connection of these boards increases the number of zones that can be controlled.

    The board can control also DHW requests moving the zone outlets if necessary.

    GENERAL FEATURES
    • Designed in compliance with standard EN60730 (European standard for automatic control devices for domestic and similar use).
    • Control for boilers with contact for high or low voltage room request.
    • Microcontroller technology which guarantees timing precision in the whole range of operating temperatures.
    • Possibility to control a modulating valve to adjust the temperature of low temperature systems.
    • Boiler Comms protocol.
    • Connection for outside probe (only in case of low temperature with modulating zone valve).
    • Cascade connection of several boards
    • Connection for outside temperature probe
