The smart "801 Series" controller
This small, stylish surface mounted controller allows for easy on/off switching. With the push of a button, the digital display lets you adjust the set-point temperature between 5°C to 32°C. Designed with a built in thermostat, the controller will also display the ambient temperature and regulate the room temperature more evenly. An advanced diagnostic mode will display codes to identify unintended shutdowns. E.g. no fuel supply, low voltage, overheating due to restricting air inlet / outlets.
A 7 Day Programmable Controller is available as an upgrade however it isn't as simple to operate as the 801 controller and normally used for passenger coaches.
