Key benefits Precise multizone control: Manage up to eight independent thermostats and linked zone valves to heat only the areas you choose. This reduces wasted energy and gives each room or floor its own schedule. Flexible integration: Works with electric heating actuators and provides passive connections for heat pumps, boilers, and external water pumps, making it suitable for many central heating configurations and retrofit projects. Clear status and reliable protection: Frontpanel indicator lights show valve and zone status at a glance. Builtin exit delay (200 seconds) and wide input voltage range protect components and stabilize system operation. Main features Multizone temperature control: Supports up to 8 thermostats. Each thermostat controls a dedicated zone valve and up to 3 normally closed actuators per zone for radiator or manifold control. Centralized signal processing: Accepts inputs from floor heating sensors or thermostats and centrally issues open/close commands to electric valves for coordinated operation. Compatibility: Direct drive for electric actuators; passive/dry connections for heat pumps, boilers, and external water pumps so the controller can integrate with existing central heating equipment. Visual indicators: Status LEDs for each zone/valve to make commissioning and troubleshooting straightforward. Durable, compact design: ABS housing, dimensions 177 x 110 mm — compact enough for wall or panel mounting in boiler rooms or service cupboards. Power and protection: Rated for 100–240 VAC input. Includes a 200second exit delay to reduce mechanical stress and prevent rapid cycling of valves and pumps. Practical applications Multistory family home: Control separate floor heating circuits for ground floor, first floor and attic, each with its own thermostat and valve group. Set different schedules and temperatures for living, sleeping and utility areas to improve comfort and reduce bills. Small guesthouse or multiapartment retrofit: Install one controller to manage independent heating schedules for up to eight rooms or apartments, while keeping a single boiler or heat pump as the heat source. Use passive connections to coordinate boiler/pump operation. Mixedsystem central heating: Combine underfloor heating zones driven by electric actuators with a heat pump or boiler. The controller handles thermostat inputs and opens/closes zone valves, while passive outputs trigger the heat source and circulation pump as needed. Why customers choose this controller Saves energy by zoning and avoiding wholesystem heating when only parts of a building need warmth. Simplifies integration with common heating hardware: electric actuators, heat pumps, boilers and external pumps. Reduces wear on equipment with a protective exit delay and wide voltage tolerance. Compact, robust construction for reliable longterm operation and easy installation.
