1.3.1 SELECTABLE TEMPERATURES
The appliance is set at the factory to allow the selection of a maximum temperature of 50°C. This limit is generally
more than adequate for most of the domestic uses, but it is possible to modify it according to your needs. A Rinnai
specialized technician can modify the device electronics by modifying the maximum allowed temperature, bringing it
to a higher value or limiting it further. This change is not permitted to domestic users. Rinnai recommends setting the
appliance to the minimum temperature best suited to the intended use to reduce gas consumption and to increase the
life of the appliance.
The control panel supplied with the appliance is factory blocked: it is possible to increase the temperature up to a
limit of 50°C. Higher temperatures can be obtained only after having unlocked the control panel: correctly performed
the release procedure, it will immediately be possible to increase the delivered temperature and reach the maximum
value set on the appliance. The unlocking (and locking) procedure is described in the section dedicated to installation
instructions, and it is allowed to specialized personnel only.
The temperatures that can be selected using the control panels are as follows:
