-
Modular design – perfectly suited for adapting to customer’s heating infrastructure with following devices: Thermostat interface, heating/cooling demand module, sensor interface and pump control.
-
Base module H10-B for direct drive of thermoelectric radiator valves: either 10 heating or cooling zones (one valve control output per zone, two-pipe system); or 5 heating and cooling zones (two valve control outputs per zone, four-pipe system); advanced PI control loop to determine heating demand and cooling demand; features a real-time clock with back-up battery for autonomous schedules; works with temperature, occupancy or combined environmental sensors, both “classic” and energy-harvesting Zigbee green power sensors.
-
Can work in conjunction with other thermostats in a leader/follower setup.
-
Compatible with Legrand’s in-wall thermostat UI Model No. 0 663 40.
-
Different operating modes: Under normal operating conditions thermostat set-points, occupancy information and temperature readings are used for closed-loop control of the temperature; When sensor reports are missing the device enters back-up mode and applies default valve opening values with different pre-sets for summer and winter seasons; Automatic temperature regulation of the built-in thermostat can be overruled by setting arbitrary steering values per valve output, e.g. 10%, 50% or 100% using zigbee level steering; Pass-through mode allows legacy wired in-wall thermostats to control valve outputs, i.e. the valve behaves like it was directly wired to the legacy thermostat; Manual mode allows valve control using a button (bypassing valve settings determined by either the Zigbee thermostat, legacy thermostats, or Zigbee level steering).
-
H10-230B and H10-24V employ staggered switching of valves to spread excessive valve turn-on currents over a time.
