MC-91A Controller Programming
Question 1: Are four Controllers connected ?
IF YES: You will need to activate the fourth controller.
STEP 1:
For the Controller in the ‘KITCHEN’ only, press and hold the
‘Transfer’ and ‘On/Off’ buttons simultaneously (see fig. 1) until a
‘beep’ is heard (approximately 5 seconds).
STEP 2:
Check that the display on ALL FOUR controllers is lit and
displaying a temperature when ‘switched on’. If any ONE of the
controller displays two dashes (see fig. 2) in the display repeat
STEP 1.
This completes the activation procedure. Ignore Question 2.
IF NO: (You have three controllers or fewer), go to Question 2.
Question 2: Is your water heater labelled “THIS APPLIANCE DELIVERS WATER
NOT EXCEEDING 50° C IN ACCORDANCE WITH AS 3498” on the front cover?
IF YES: No further action required.
IF NO: You will need to program the Kitchen controller to enable selection of temperatures higher than
50º C.
STEP 1:
For the controller in the KITCHEN only, press and hold the 'Transfer' and 'On/Off' buttons
simultaneously (see fig 1.) until a 'beep' is heard (approximately 5 seconds).
STEP 2:
When the controller fitted in the KITCHEN is switched on, it should be possible to select temperatures
higher than 50º C. If not, repeat Step 1.
Note:
• If the kitchen controller is replaced, repeat STEP 1 above for the replacement controller.
• If the kitchen controller is swapped with another controller (for example, the controller fitted
in a bathroom), repeat STEP 1 for the controller moved from the kitchen to the bathroom.
Then perform STEP 1 for the controller moved from the bathroom to the kitchen.
