The ET Series Plant Extension timers have been designed to provide a simple way to extend the running hours of a plant or a system. The extension timers are available with different maximum extension periods, ET1 up to one hour, ET5 up to 5 hours and ET10 up to 10 hours. Custom time periods are also possible, please consult SyxthSense Sales for more information.
The timers have 7A 230Vac relay for switching the plant on/off, both normally open and normally closed models are available. The five green LEDs on the fascia of the unit indicate the current extension time and the red on/off LED indicates the status of the relay.
The units have built-in HOLD contacts (default open). When the hold contacts are open the timer starts counting down immediately after selecting the required extension time. If the HOLD contacts are closed, the timer is in hold mode and the timer does not start counting down until the contacts are opened (LEDs flash slowly).
The extension timers have touch sensitive push button for the selection of the extension time.
The maximum extensions time can be limited through the configuration mode.
The ET extension timers are flush mounted to a UK or European wall box, or can be mounted directly on a panel door.
