HiSmart HT260393 4-loop underfloor heating manifold set with NC 230 V thermal actuators and flow meters

The HiSmart HT260393 is a complete 4-loop manifold set for zoned hydronic underfloor heating. It combines a flush-mounted metal cabinet, a 4-loop collector, 4 flow meters and 4 normally closed 230 V thermal actuators.

Control and connections

• The manifold distributes warm water to individual heating zones; the flow meters support flow monitoring and hydraulic balancing.
• The normally closed actuators accept control signals from compatible programmable or non-programmable room thermostats or a heating controller.
• Each actuator connects through a VA80 adapter to a standard M30 valve thread.
• The set also includes two air-vent assemblies and 4 adapters for 16 mm heating-circuit pipes.
