Each master module is capable of controlling 8 heating zones, each of which may use one or more
loops of piping, with one or more thermal actuators.
These zones are referred to later in this manual as channels 1 to 8. If more than eight zones are to be
controlled, it is necessary to install an add-on (AO) module, which provides another six outputs. The
AO module then controls channels 9 to 14.
