For safety and comfort the thermostat will shut off the mixing valve
within
2 Seconds
if either supply fails (achieved only if the blend temperature has
a minimum differential of 12°C from either supply temperature).
Thermostatic Shut-down
Temperatures
Close temperature control
20°C - 50°C
Optimum Thermostatic Control
Range
35°C to 45°C
(achieved with supplies of 15°C cold, 65°C hot and
nominally equal pressures)
Recommended Hot Supply
60°C to 65°C
Minimum Hot Water Supply Tem-
perature
55°C
(
Note:
The mixing valve can operate at temperatures
up to 85°C for short periods without damage.
However for safety reasons it is recommended that
the maximum hot water temperature is limited to
65°C)
Minimum Recommended
Differential between Hot Supply
and Outlet Temperature
12°C at desired flow rates
Cold Water Range
1 - 25°C
Specifications
Pressures
Maximum Static Pressure
1000 kPa (10 bar)
Maximum Maintained Pressure
500 kPa (5 bar)
Minimum Maintained Pressure
(Gas Water Heater)
100 kPa (1 bar)
(for optimum performance supplies should be
nominally equal)
Minimum Maintained Pressure
(Gravity System)
20 kPa (0.2 bar)
(0.2 bar = 2 Metre head from cold tank base to shower
