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.
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
Sundial RF 2 Pack 3 contains a wireless enabled programmer (ST9420C), a wireless thermostat (DT92E), and a wireless cylinder thermostat (CS92A). In a stored hot water heating system which has no room thermostat or cylinder thermostat the existing wiring can be used to provide Boiler Interlock by fitting Sundial RF 2 Pack 3.
Long term protection of mixed metal and plastic central heating systems against corrosion, limescale and deposits. Bottle contains sufficient chemical to treat up to a 10 radiator system.
