1.3.5 UNIVERSAL WATER CONTROLLER (MC-601) OPERATION
Turning on
If the water controller is switched off (no digits displayed in the digital monitor
window) press the On/Off button once. The ON indicator will illuminate,
indicating that the hot water unit will be ready to supply hot water once a
hot water tap is opened.
Adjusting temperature
Select the desired temperature using the Hot water temp or buttons
until the required temperature is displayed on the digital monitor.
To operate the hot water unit, open any hot water tap. This will automatically
light the burner providing hot water. The water heater ‘In Use’ indicator will
illuminate on the water controller(s).
Once the hot water is running, if the set temperature is either too hot or cold
press the Hot water temp or buttons until the desired temperature
is reached.
NOTE
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.
Temperatures higher than 50ºC must not be able to be selected on controllers installed in bathrooms,
ensuites or toilets. This is to help reduce the risk of burns from hot water. If this is not the case, the
controllers have been incorrectly installed. Contact your installer.
The 'beep' sound can be muted by pressing the and buttons simultaneously for more than 3
seconds. To cancel sound muting, simply repeat the process.
CAUTION
Always check outlet water temperature before use. The parent/carer MUST check the temperature
before placing dependants in contact with hot water.
Transferring priority
To control the water delivery temperatures when using two or more water
controllers it is necessary to have priority transferred to the water controller
you wish to use. Transferring of priority will NOT be possible if the ‘In Use’
indicator is currently illuminated, as this indicates hot water is flowing and
that another water controller already has priority.
An illuminated priority indicator confirms that the desired water controller
is in control of the water delivery temperature. If the priority indicator is
not illuminated press the priority transfer button once. The priority indicator
will illuminate, indicating that hot water temperature control has been
transferred and that the hot water unit will be ready to supply hot water
once a hot water tap is opened.
