Diamond-H WTS Dual Function Wired (not push fit) Rod Thermostat Dual Function Rod / Stem Thermostat 80°C Control, 90°C Safety

Product Code: ST-704

This is a Dual Function Rod / Stem Thermostat with adjustable trip and fixed safety cut-out.

Operational switching is achieved via single pole stem control and a manually re-settable safety cut-off is via a capillary system.

Employing a capillary system for safety allows the benefit of sensing the water or fluid temperature within the vessel rather than the surface temperature of the tank/cylinder which gives far greater accuracy in switching.

The Diamond-H WTS thermostat is CE marked and ENEC approved to EN 60730 (-1:2000, -2-9: 2002) and EN 60335 (-1: 2002, -2-73: 2002).

Direct equivalent to Cotherm TSE, Cotherm TSR, Thermowatt RTS ranges

Key benefits over competitors:

  • Higher accuracy control and safety switching (capillary action safety sensing directly in the tank/cylinder)
  • Plug in system
  • 20 Amp 250 V AC
  • Tested to 100,000 operation cycles (higher reliability than common competitors)
  • Type 2 approved control


Most commonly installed in immersion heaters for commercial applications such as Heatrod HR, HRZ, HRi ranges.
