  • Features & Benefits

When all the TRVs are open, the by-pass valve remains closed, allowing the full boiler output to circulate around the heating system. As the TRVs sense that the selected room temperatures are reached and begin to close, the by-pass valve starts to open, maintaining optimum flow through the boiler, thus eliminating possible damage to the boiler and pump. Installation of a by-pass valve also minimises the noise often experienced when flow rates through the boiler decreases
