At the heart of every lemonpeel control system is the Leo, the flexible, powerful controller. The Leo takes on many roles from hardware management through the wide range of inputs and outputs to user interaction and through its web based dashboard. All settings are changed directly on the Leo with no additional software required. With just a power socket and a network connection the Leo is ready to interact with your building.
As the Leo contains the intelligence of most modern smartphones, unique control scenarios can be set up to suit your individual needs.
Only switch the heating on at 9am on Tuesdays if someone is in the hall...
What and how you choose to control in your building is only limited by your imagination. Contact us today.
All of the settings and data on the Leo are accessible via the Dashboard. This is a web based interface panel that is accessed via an internet browser on your computer or mobile device. The Dashboard allows for setting and modification of your scheduler, setting the events for the upcoming week from from the comfort of your computer, tablet or on the go, on your phone.
Turn on carpark lights when it gets dark but off at 1am except on weekends when I want them on all night....
Unlike most heating or lighting time clocks, there is no limit to the number of channels or events in your scheduler. You can set as many times as you like and add notes to identify which event the setting relates to to help keep track of your weekly schedule. Options for Weekends, Weekdays and Everyday allow for broader control.
With Prewarm enabled, the Leo will calculate how long is required to heat the space from the current measured temperature to the next set point ensuring that your building is always at the correct temperature when events start.
For heating systems, one of the most crucial features is zone by zone temperature control, often known as thermostatic control. Traditionally a crude thermostat is installed on a wall with a dial on the front but these struggle to accurately measure the temperature as well being easy to tamper with. The Leo collects temperature readings from discrete temperature sensors positioned in the heating zone connected via either cable or radio signal. These provide the temperature to the nearest 1 degree and allows for a very accurate switching of the heat source.
Further options allow for multiple sensors to be averaged together, exterior sensors, humidity sensors and flow and return pipework temperature sensors.
I need my supply ventilation to run when the internal temperature gets too high but only when the external temperature isn't below 10 degrees...
You can connect multiple zones to the Leo via the volt-free contacts. A zone can be assigned one or more outputs if multiple heating sources are used in the zone.
Zones don't just have to be rooms, as large halls can contain multiple zones all individually thermostatically controlled but via one scheduler.
Input and Outputs
A vast array of inputs and outputs can be configured on the Leo via the input I/O expansion boards as well as via radio signal.
Straight out of the box, the Leo contains:
Each Leo comes 1No. 2-Way I/O expansion board providing the following connections.
Further I/O options are available
The Volt-free outputs can be used for a number of applications including switching a 230VAC load like a boiler, pump or lighting circuit. With a 10A switching capability, each output can switch up to 2300W. DC loads like pumps, LED lighting and extra-low voltage contacts on boilers can be switched with the same outputs.
In addition the outputs can be used to switch much larger loads via a third party contactor including banks of electrical heaters, flood lights or three-phase loads.
Both normally open (NO) and normally closed (NC) contacts are available for all outputs
