Zones Setup
Unswitched Zones- (Common Zone)
The system is capable of operating a common (or unswitched) zone allowing all
other zones to be turned off.
In the unswitched zone parameter, set the parameters required according to HE
parameter table.
1 – Allows all other zones to be switched off
0 – Will not allow all zones to be turned off and one must always be on.
Switched Zones
The system is capable of controlling up to 8 switchable zones. The number of zones
shown in the display is set from parameter 2 in the Ducted Gas Central Heater
Installer Parameter table. The Navigator Controller needs to have parameter 2
changed to 127, this will display all zones on the controller.

MULTIPLE CONTROLLERS – SHARED ZONES
Single DGCH with individual zones and multiple Navigator controllers
For multiple Navigator controllers, the best results require one Navigator measuring
the temperature in zones 1 & 2, the other measuring zones 3 & 4. None should
measure the common zone. This assumes that the Navigators are physically
installed in Zones 1 and 3 respectively
