Operation - Mira 415 Installation And User Manual

Mira 415 shower controls have a single sequential control knob. The shower control
is turned on by turning the control knob anti-clockwise. The shower control is turned
off by turning the control knob clockwise. When the control knob is turned on
(anti-clockwise) the sequence is;
Cold water  Warm water  Preset maximum temperature.
A fuller description is as follows:-
1. Initial anti-clockwise movement turns the water on at full flow of cold water,
further anti-clockwise movement increases the temperature. The flow rate
is determined by the supply pressures at the inlets of the shower control,
or by the effective output power of the heater appliance. Flow rates for gas
heater appliances can vary typically between 8 l/min (winter) and 15 l/min
(summer).
2. The control knob incorporates a red override button, which allows movement
beyond the adjustable maximum adjustable temperature stop. When the
adjustable maximum temperature stop is reached, the override button can be
pressed allowing the control knob to rotate further. This facility is used when
the initial hot water supply temperature has fallen due to increased demand or
when a hotter shower is required. The override mechanism is self cancelling
when the knob is returned to the off position.
3. For safety reasons this product is fitted with a adjustable maximum temperature
stop. This setting must be checked and adjusted as necessary to suit both site
conditions and user's comfort. Refer to the section "adjustable maximum
temperature setting" for further details.
