OPTIONAL PROGRAMMING FOR THE 'UNIVERSAL' WATER CONTROLLER (MC-91Q)
Are there four water controllers connected ?
QUESTION
IF NO: (You have three water controllers or fewer), go to Question 2.
IF YES: You will need to activate the fourth water controller as follows:
STEP 1: For the water controller in the KITCHEN ONLY, press and hold
the 'Transfer' and 'On/Off' buttons simultaneously (see Fig. 5)
until a 'beep' is heard (approximately 5 seconds).
STEP 2: Check that the display on ALL FOUR water controllers is lit and
displaying a temperature when 'switched on'. If any ONE of the
controller displays two dashes (see Fig. 6) repeat STEP 1.
This completes the activation procedure for the fourth controller,
you may ignore Question 2.
Is the water heater marked to state it delivers water
not exceeding 50°C ?
QUESTION
IF YES: No further action required.
IF NO: You will need to program the kitchen controller to enable
selection of temperatures higher than 50°C.
STEP 1: For the controller in the KITCHEN ONLY, press and hold the
'Transfer' and 'On/Off' buttons simultaneously (Fig. 7) 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 50°C. If
not, repeat STEP 1.
If the water controller in the kitchen is replaced, repeat STEP 1 above for the
replacement controller.
NOTE
If the water controller in the kitchen 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 bathroom to the kitchen.
