PRE-SET TEMPERATURE
The Bosch water heaters are factory pre-set to operate at 55°C (or 50°C on 50
degree model) without temperature selector pads. The pre-set temperatures can be
altered to 60°C or 75°C, (or 42°C on 50 degree limited unit) by changing the setting
of the CPU or by using the temperature bridges supplied. Refer to page 13 for
details.
The appliance can also be fitted with temperature selector pads, available as an
accessory item. When fitted, the hot water will be delivered at the temperature
displayed on the selector pad.
There are two versions of remote controls available, the 66 series which has bath fill
alarm and the 67 series which has bath fill stop.
The two different series must never be connected to the same water heater.
The sub controller cannot be used as a sole controller.
There is a Main, Bathroom and Ensuite control available in each series, never
connect more than one of each control type to the water heater (except an extra sub
controller as the fourth controller.)
Only one of each type can be connected to the appliance.
