E312/3hr/24V Plant Extension Timer

Our plant extension timer will operate HVAC equipment outside of normal system operating times.  Touch sensitive buttons and intuitive functionality make it easy to use and operate. A remote start facility is included as standard which means that the extension will not commence until a signal is received.

The E312/3hr/24V is a mains powered single-shot plant extension timer designed to control plant equipment such as heating, lighting or air-conditioning systems outside of normal occupancy hours.  Suitable for installation into a single-gang UK pattress/back box or a control panel, it provides a voltage-free changeover relay output capable of switching loads of up to 16A (4kW) which is activated for a selectable time period.

The E312/3hr/24V is extremely user-friendly with a single touch-sensitive pushbutton used to select the required extension between 30 minutes and 3 hours (selectable in stages of 30 minutes).  The plant extension timer has 6 LED indicators to indicate the remaining extension time period and a single LED to illustrate the status of the output relay.  The extension LEDs also have a very low level background illumination which enables the unit to be easily located and controlled in poorly lit areas.

A remote switch input feature is provided so the extension timer can be activated by a remotely located switch or other timer.  The E312/3hr/24V timer runs when the remote input contacts are closed or is paused when the contacts are open, thus enabling multiple E312/3hr/24V units to be linked together to add a delay before the extension period, or to provide activation from a remote location.

The E312/3hr/24V also provides the functionality to pre-set a maximum extension period via an internal thumbwheel to ensure that the end-user cannot select an extension period longer than the authorised user so desires.
