  • Zoning board

    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.

    • 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
