Step 2 - Assembly - Warmup WHS-M-S3-Series Installation Manual

Step 2 -
Assembly - Mixing Unit
The Warmup WHS-M-S3-MIX Mixing Unit is required for all
installations where the temperature of the water provided by the heat
source exceeds the design water temperature of the floor heating
system.
This includes all heat sources which intermittently 'over heat' due to
sterilisation cycles or uncontrolled heating.
The Mixing Unit, enables the manifold to regulate the secondary flow
water temperature to between 20°C and 60°C, for tailored system
performance.
1
• Remove WHS-M-S3-MIX mixing
unit from packaging. Keep
the thermostatic capillary
actuator and sensor to one
side, these will be fitted during
system commissioning.
