TEMPERATURE CONTROL
WATER VOLUME FUNCTION
The function provided by the water volume button and alarm is to warn, by a beeping
sound, that a certain volume of water has been delivered from the water heater. It
does not stop either the flow of or the heating of water. This function is particularly
useful if a bath is being filled, or measuring the water consumed by the use of a
shower. The water volume function can only be set by the Kitchen controller.
Operation
To use the water volume alarm:
1. Press the water volume button.
The light in the water volume button will glow.
The current set water volume (in litres divided by 10) will be displayed and the
x10l indicator will also glow.
Eg. the factory preset water volume of 180 litres is shown as 18 x10l.
2. Adjust the water volume setting (if necessary).
To adjust the water volume setting, press the up (▲) button to increase the water
volume or the down (▼) button to decrease the water volume. Each press of the
up (▲) button or down (▼) button will change the water volume setting by 10
litres. Pressing the up (▲) button or down (▼) button continuously will scroll the
water volume setting.
Fifteen seconds after the water volume has been selected, the water volume
light will start to flash and the selected water volume is set. The water volume
light will continue to flash until the alarm sounds.
A maximum of 500 litres (50 and x10l displayed) and a minimum of 10 litres (1
and x10l displayed) can be set with the water volume alarm.
3. Turn on the controller for the room where the hot water is to be used, gain priority
and select the temperature setting.
4. Open the hot tap to draw hot water.
Measurement of the water flow at the water heater will commence when the
water volume light is flashing and a hot tap is open.
The alarm will sound when the set volume of water has passed through the
water heater.
5. Press the water volume button to turn off the alarm.
The water volume light goes out and 0 x10l is displayed momentarily on the
controller. The temperature setting of the controller with priority is then displayed.
6. Close the hot tap.
