The water can be controlled by the utility via the
RF module installed. Where this communication
mode is not available the unit can be operated
in standalone mode (i.e. when communications
with the utility are cut off, the cylinder operates in
standalone mode). In this mode the heater tries
to achieve 60°C at T1 and tries to maintain this
throughout the day. The communications of the
appliance can be changed as shown in Figure 12.
7.2.3 Set Communication Mode
The water can be controlled by the utility via the

conguration.
- Timed tariff requires that time period is set
during which the cylinder will be heated to the
primary temperature set-point. This heat up or
charge period on the cylinder to be aligned with
any low cost energy tariff available. See Figure 8
