Temperature Control
Minimum temperature differential between hot and outlet temperature: 10°C
Optimum temperature control range: 35 - 45°C
Maximum hot water temperature: 85°C (for safety, a recommended hot water storage
temperature maintained below 85°C and for ablutionary installations at between 60 to
65°C).
The performance specification outlined below is achieved with outlet blend temperature
set between 35 - 45°C and supplies of 15°C cold and 65°C hot with nominally equal
pressures.
- Outlet blend temperature is maintained within 2°C with a 10°C change in
hot or cold supply.
- Thermostatic shut down to seepage within 2 seconds if cold supply
fails. This is achieved only if the hot supply temperature is 10°C above
the set outlet blend temperature.
