The MRT16 series of time delay switches are designed to provide timed control of lighting, heating or ventilation loads.
Using push button, touch (light press required), pull cord or remote activation, the user can switch on a load for a preset time period and have the load turn off automatically after the time period has elapsed.
Multiple timing ranges come as standard to allow the time out period to be set accurately. Time setting is achieved using switches and a thumbwheel at the rear of the unit.
Several modes of operation are selectable using switches:
- On/off: triggering the timer will turn on the load and start the timing. Triggering the timer again during timing will immediately turn off the load and stop the timing.
- Resetting: triggering the timer will turn on the load and start the timing. Triggering the timer again during timing will re-start the timing period from scratch. When using an external trigger In this mode, the timer will not start until the trigger is removed making it ideal for pump or fan overrun applications.
- Non-resetting: triggering the time will turn on the load and start the timing. Triggering the timer again during timing will have no affect.
Optional neon indicators provide permanent illumination or illumination during the timing period.
