CONFIGURING THE TOTAL SYSTEM
Each master module is capable of controlling 6 heating
zones, each of which may use one or more loops of
piping, with one or more thermal actuators. These zones
are referred to as channels 1 to 6. If you wish to control
more than 6 zones, it is necessary to install ADD ON (AO)
modules, each of which can provide another 4 outputs.
The first AO module then controls channels 7 to 10, and
the second module controls channels 11 to 14. This is
achieved by setting a switch in the AO module to either
7/10 or 11/14. All the thermostats of the complete system
must be connected to the master control, and not to the
AO modules.
Position A/B
A: Acting on demand from thermostat 7->10
B: Acting on demand from thermostat 11->14
Connection of master and add on module
The master is connected to the add on module using the
4 terminals marked AO-MODULE. Connect B to B, A to A,
- to - and + to +. Max distance between the master and
add on module is 30 m.
