Technical information
Principle of Operation

This fully thermostatic shower control mixers hot and cold water to the desired showering temperature and automatically compensates for variation in both the temperature and pressure of the inlet water supplies to maintain the blend temperature.

Limitations of Use
The Mira Excel should not be used for applications where an outlet flow control forms part of the shower fitting.
The product and its components are only suitable for normal water supplies and should be cleaned only with mild washing detergent or soap solution. Light golden products should be cleaned using a soft damp cloth only.

Wax capsule temperature sensor
Automatic shutdown to seepage within two seconds if cold supply fails
Adjustable override and maximum temperature stop (may be disabled)
Temperature control range: 30°C – 50°C
Maximum hot water temperature: 85°C (BS6700 recommends a maximum 65°C)
Minimum temperature of differential: 12°C (between blend and hot)

Pressure (inlet supplies)

Minimum maintained pressure: 0.1 bar
Maximum maintained pressure: 5.0 bar
Maximum static pressure: 10.0 bar
Maximum pressure loss ratio: 10:1

Performance
The specification performance outlined below for the low pressure setting is achieved with inlet water supply temperatures of 15°C cold 65°C hot and nominally equal inlet supply pressures:
Close thermostatic control achieved in the range 30°C to 50°C
The blended water temperature is maintained within 1°C with a 10°C change in the hot and cold supply.
The Mira Excel will affect a shutdown to seepage in typically two seconds if the cold supply.
Shutdown to seepage is affected only if the hot supply is a minimum of 12°C above the blend temperature.
The blended water is maintained with -/+1°C with a pressure loss ratio of 2:1 on either the hot and cold side.
