7 day programming (7 day, 5/2 day or one day) with a choice of 3 different presets for energy and time saving
Automatic Bypass Valve suitable for all heating systems up to 10 bar static pressure where a boiler bypass is required or radiator thermostats are fitted. It provides a simple method of ensuring adequate flow through boilers which require a bypass as well as reducing system noise. In systems fitted with radiator thermostats, the valve opens automatically as the TRVs or zone valves close down and the resistance of the system starts to exceed the preset pressure limit.
High quality brass-bodied three-port mid-position motorised valve, for automated control of the flow of hot water to heating or domestic hot water, or both services simultaneously
The V4073A Valve has been designed to control the flow of water in domestic central heating systems, where both radiator and hot water cylinder circuits are pumped. It is typically suited for small to medium sized installations
