## Summary description

HiSmart HT260393 is a heating manifold designed for hydronic systems, featuring 4 loops and normally closed (NC) thermal actuators operating on AC 230V. It provides individual circuit control for radiator or underfloor heating zones, enabling automatic on/off regulation. Suitable for residential and light commercial installations where zoned temperature control and reliable actuator operation are required.

## Long description

HiSmart HT260393 is a flush-mounted underfloor heating manifold with four heating loops, supplied flow meters and normally closed (NC) thermal actuators operating at AC 230V. The set includes a metal flush mounting box with a hinged door, a 4-loop collector, flow meters and four NC thermal actuators. The unit is intended as the control centre for hydronic underfloor or radiator heating systems, allowing individual control of each zone and measurement of water flow for balancing and monitoring.
Advantages
The manifold enables precise zoned control, reducing unnecessary heating of unused areas. NC thermal actuators receive signals from thermostats or controllers and modulate water flow for accurate temperature regulation and lower energy use. Flow meters allow easy visual monitoring and fine adjustment of circuit flows. The compact flush-mounted cabinet with a 135° opening door provides tidy installation and service access.
Suitable for (tasks / use cases)
Residential underfloor heating systems with up to four heating zones
Small commercial or light-commercial hydronic installations requiring zoned control
Systems that use room thermostats or a central controller to manage heating zones
Installations requiring flow monitoring and balancing on each circuit

How to use
Install the metal cabinet flush into the wall and secure the collector inside the box. Connect supply and return pipes to the corresponding inlets and outlets using the supplied 16 mm pipe adapters. Fit the thermal actuators onto the manifold valves via the VA80 adapter and make electrical connections to your room thermostats or controller (AC 230V). Use the flow meters to balance each loop by visually checking and adjusting flow until desired rates are reached. Ensure air vents are opened to purge trapped air before commissioning.
Usage recommendations
For reliable operation, use compatible room thermostats or a hub controller sized for AC 230V actuator outputs, verify electrical connections and ensure the system is flushed and free of debris before fitting actuators. Regularly check flow meters and bleed vents during the first heating cycles to maintain balanced performance.
