Ventmiser CMSM

Ventmiser CMSM (Carbon Management Switch Module) is a control device which activates/speed controls an extract fan, MEV or MVHR system when either a current (electricity) sensor or pipe temperature sensor signals the switch module.

Current (electricity) sensors can be fitted to items such as cookers and electric showers.

Temperature sensors can be fitted to copper pipework supplying plumbed showers and baths.

The Ventmiser system automates a ventilation system, help prevent condensation problems and can assist in the reduction of false fire alarms.


  • Auto control, there is no need for switches.
  • Energy savings by boosting fan only when moisture/ cooker odour generating activities are taking place.
  • Adjustable overrun timer can be set to suit requirements.
  • Easy to install with either current and/or temperature sensors for total flexibility (requires access for wiring etc)
  • Simple to commission.
  • Removing other odours
  • Automates a ventilation control system

Switch module - 159mm x 85mm x 45mm

Sensors supplied with 12m of fitted cable
