INSTALLATION
Connecting the zones to the BoilerMate.
The space heating flow should be taken from the BoilerMate connection into the space
below the platform. The flow can now be split into the appropriate amount of zones
and a controlling zone valve fitted to each branch. Each flow can then be piped to its
radiator zone and the heating return brought back to the space below the platform.
The heating returns can now be connected together before a single connection is
made to the heating return on the BoilerMate.
A typical way of providing heating and hot water time control is shown below.
However, other methods can be used such as using a 3 channel programmer if required.
