WB10 Wired Wiring Centre

The WB10 is an 10 Zone wiring centre for use with 230v thermostats, the outline dimension is 32cm x 14cm x 5.5cm. the WB10 can be used  to control any actuator or valve which requires a 230v AC signal to open.  For mid position valves and those requiring a closing signal, a changeover  relay is required. At the same time the WB10 offers the ability to operate  a boiler or other heat source through a volt free output. Additional outputs  designed for use with under-floor heating systems are also included as  standard. These are the pump and valve outputs which would normally  operate a manifold pump or a manifold valve.

WB10 has a feature of pump delay , user could set it 3mins or 0 min by  adjusting the switch on the pcb , the pump output delay time is 3 minutes  if switch is set to “1” ; the pump output delay time is 0 minutes if switch is set to “ON” ; the pump delay switch is close to the fuse on the pcb  board.

Zone 10 can be used as an isolated radiator zone, by using the UFH/RAD  switch. If the switch is set to RAD; When zone10 calls for heat this will provide an output to a radiator zone  valve and the boiler, but WILL NOT enable the under-floor heating pump /valve output. If the switch is set to UFH; When Zone 10 calls for heat, this will act as an under-floor heating zone, by enabling the actuator, boiler and pump/valve outputs.Any output  which is not needed can be ignored.

UFH Pump：

Used for an underfloor heating manifold pump, connections are; L = Live, E = Earth, N = Neutral When an under-floor heating zone sends a call for heat to the WB10,  the live & neutral output will supply 230v to the manifold pump . The  pump and boiler delay time is 3 minutes if switch in 1 ; The pump and  boiler delay time is 1 minute if switch in ON ; It is recommended that this is fed through a high limit switch placed on  the heating manifold, to protect against mechanical failure of the  manifolds temperature control.
