TURNING ON THE WATER HEATER.
When the water heater is in the ‘Off’ condition only the communications
and battery status indicators are displayed on the digital monitor.
To turn the water heater ‘On’, press the On/Off button once (if Child lock
is activated see page 12). The communications indicator will
briefly illuminate to confirm that a signal has been sent to the transceiver
connected to the water heater.
The transfer indicator and the water temperature display will flash until
communication between the controller and transceiver is complete. When
the display stops flashing the water heater is ready to supply hot water.
ADJUSTING TEMPERATURE
Simply press the 'hot water temp' or buttons until the required
temperature is displayed on the digital monitor. The water temperature
and any active status indicator will flash until communication
between controller and transceiver is complete. DO NOT open the hot
water tap until the flashing stops and the desired temperature is displayed.
To operate the water heater, open any hot water tap. This will
automatically light the burner, providing hot water. The ‘In Use’ indicator
will illuminate on the water controller.
Once the hot water is running, if the set temperature is either too hot or
cold press the or buttons until the desired temperature is reached.
Whilst hot water outlets are open the set temperature may be
lowered to a minimum of 37°C. For safety, it cannot then be
raised above 43°C until all hot water taps are closed.
If the water heater is turned ‘Off’ whilst hot water taps are
open it can not be turned back ‘On’ until all hot water taps
have been closed.
Always check water temperature at the outlet before use.
A parent or carer should always check the temperature
