19 INDEPENDENT SYSTEM CONTROLS
If the system controls are to be independent of the boiler, then the following method should be used for connecting the boiler.
No parameter modifications are required.

* The switched live from external
controls must be from the same
phase supply as the boiler mains
supply to ensure that when the
boiler supply is switched off the
controls are also isolated.

This system provides heating to one zone at a time with DHW
priority controlled by parameter 43. To heat more than one zone
simultaneously, use zone thermostats to energise individual
zone valves with all calls for heat applied to 'CH CALL'. The
boiler will be limited to responding with a set flow temperature
set by parameter 4. If all zones are fitted with individual zone valves a hydraulic
bypass will be required to allow pump overrun. See page
5 and 6 for details.
