The Speed Control Pack is simply transferred from the unit to the T-Series Controller.

The new T-Series Controller features an AutoSensor mode which allows you to use one of a range of sensors with T-Series fans.

• Timer
• Thermostat
• Humidistat
  

Used together, T-Series units, Controllers and Sensors can build into an 'intelligent' ventilation system with the flexibility to control indoor environment.

T-Series Controllers are compact and share the T-Series styling. The Controller utilizes the Speed Control Pack, which is transferred from the ventilating unit at installation. Three slide switches give the user access to nine functions - three speeds; low, medium, high; the choice of exhaust or input operation - plus features new to unit ventilation including a shutter open, fan off position and Auto-Sensor mode. Program the Controller, then switch to auto-mode for automatic ventilation using a humidity or temperature sensor. And because it only switches on when necessary it saves energy and uses a minimum of electricity to maximum effect. Switch to 'ON' and manual control is again possible.
