Control Principle
|
Manual Mixing Arrangement
An adjustment changes the proportion of hot and cold water
entering the mixed outlet.
|
Thermostatic Arrangement
A temperature-sensitive element adjusts the mixture within
the valve’s documented operating envelope.
|
|
Supply Variation
|
Manual Mixing Arrangement
A fixed adjustment can produce a different outlet temperature
when inlet conditions change.
|
Thermostatic Arrangement
Regulation depends on compatible inlet temperatures,
pressures, flow and installation conditions.
|
|
User Adjustment
|
Manual Mixing Arrangement
A deck-mounted lever or an under-basin mixer may provide the
adjustment, depending on the model.
|
Thermostatic Arrangement
The setpoint may be user-accessible or secured for facility
adjustment, depending on the valve design.
|
|
Temperature Limiting
|
Manual Mixing Arrangement
A mixing handle or preset position alone does not establish
a certified maximum-temperature safeguard.
|
Thermostatic Arrangement
Confirm the device’s listing, adjustment limits and specified
supply-failure response.
|
|
Low-Flow Compatibility
|
Manual Mixing Arrangement
Confirm useful adjustment across the selected outlet’s
actual flow range.
|
Thermostatic Arrangement
Match the faucet’s delivery rate to the thermostatic device’s
minimum operating flow.
|
|
Installation Review
|
Manual Mixing Arrangement
Verify hot/cold orientation, connection sizes and access to
the adjustment and isolation valves.
|
Thermostatic Arrangement
Check required strainers, check valves, inlet conditions
and service clearances against the valve instructions.
|
|
Acceptance Evidence
|
Manual Mixing Arrangement
Record the measured outlet temperature at the intended
adjustment and normal operating flow.
|
Thermostatic Arrangement
Record the commissioned setpoint and carry out
manufacturer-specified performance checks.
|
|
Scope of Selection
|
Use the exact model’s faucet and valve documentation.
Sensor activation, temperature indication and thermostatic
protection are separate functions.
