Programming - accessing factory mode
DDSTAT with one or two pumps (p.7-8)
Used with Demand Duo systems and operates by measuring the temperature of the water in
the tank. If the water temperature falls below the tank set temperature and the tank low limit
temperature, the controller will switch on the pump(s) to circulate water through the system.
DDPCEL (p.9)
Used to monitor commercial flow and return systems. The main functionality of this mode is to
extend the life of the pumps by regular alternation, or overcome any issues with a faulty pump if
present.
DDSOLAR
(N/A to NZ)
Factory mode needs to be accessed to change the system configuration. To do this make sure the
controller is switched on and the system display is showing.
