Wireless Water Controller Operation

Transferring priority between water controllers

To control the water delivery temperatures when using 2 or more 

controllers it is necessary to have priority transferred to the controller 

you wish to use.

an illuminated transfer indicator confirms the controller is in control of 

the water delivery temperature. If not illuminated, press the transfer 

button to     

transfer the priority.

For safety reasons while hot water taps are on, transfer of priority 

between controllers is not possible.

Temperatures higher than 50 °C should only be able to be selected on the controller labelled 

‘Master’ (used in the kitchen), not those labelled ‘Bathroom’. This is a safety feature to reduce 

risk of burns.

Child lock function

To activate the child lock function

Press the key button for 3 seconds. The child lock indicator will 

illuminate to confirm that the function is now active. Once activated 

this controller will be the only controller that can deactivate it.

To deactivate the child lock

Press the key button for 3 seconds. The indicator will go out to show 

that the function is no longer active.

General functioning of the child lock

Only applies to the specific water controller where ‘child lock’ is 

activated 

While activated only the child lock control and the ‘Off’ control are functional from that 

controller 

When the water heater is turned off while the child lock is activated, it can not be turned on 

again from a controller where the child lock is activated

 

Child lock is deactivated during a battery change or when batteries fail

3 seconds
