nVent RAYCHEM HWAT-T55 thermostat for Hot Water Maintenance Systems

Overzicht

The HWAT-T55 thermostat is designed for operation with RAYCHEM Hot Water Maintenance System in small pipe networks or for branches up-to 50m.

It is compatible with self-regulating heating cable
HWAT-L
HWAT-M
HWAT-R

Key Benefits:

  • Energy savings:
    • When using HWAT-L the heating cable system can be switched OFF or ON (e.g. during absence)
    • With HWAT-M / R there's a choice of three preset temperatures 55/50/45 ° C; Ideal for fresh water technology
    • 3 operating modes: ON; ECO; OFF
    • Integrated clock & extra energy savings (Eco) for off-peak usage
  • System monitoring:
    • Over temperature alarm: if a temperature over 66 ° C is measured the system will be switched off to avoid scalding and calcification
    • Lower temperature alarm to avoid unnecessary heating & extra energy consumption when possible hot water storage problems occur
  • Easy installation and operation
