Using Hot Water
To operate the heater, simply turn any hot water

providing hot water. The red IN USE indicator
will glow on the temperature controller.
Using High Temperature Display Controllers
You will need to program the Master controller if you want to display and use
temperatures over 50°C. Programming only needs to be done on Master
universal controller; other universal controllers will not allow this.
Deluxe Kitchen controllers are supplied already programmed to allow high
temperatures.
STEP 1: On the Master controller only press and hold the Transfer and ON/
OFF buttons simultaneously (see Fig. 1) until a "beep" is heard (approx. 5
seconds).
STEP 2: When the Primary controller is switched on it should be possible to select temperatures higher
than 50ºC. If not repeat STEP 1.
If the master controller is replaced, repeat STEP 1 above
for the new controller.
