AUTOTERM Push Control L Mono is a compact stainless push-button controller for AUTOTERM Air and Flow heaters. This supplier-defined Mono version uses the 12mm round connector and a two-port control module for a simple heater-and-button installation. It suits caravans, motorhomes, campervans and boats where straightforward tactile heater control and a clear colour LED are preferred. Choose Mono or Duo This product, RVD636 Mono: two-port module with connections for the heater and Push Control button. Different product, RVD636A Duo: three-port module that can also connect a supported additional control panel. Choose the Duo product if you need the Push Control and an AUTOTERM Comfort or Comfort Boiler panel to control the same heater. The separate AT4-0014-AF0 panel wire does not add an additional-panel port to a Mono module. Check the module configuration, connector and heater model before ordering. Compatible AUTOTERM heaters AUTOTERM lists Push Control compatibility for current Air 2D, Air 4D and Air 9D air heaters, plus Flow 5D, Flow 5B and Flow 14D liquid heaters. Compatibility for older heater versions should be confirmed before purchase because available functions can vary. How the Push Control works AUTOTERM Air heaters Without an external temperature sensor, short presses step through five heater power settings. With a compatible external temperature sensor, the button provides 18°C, 21°C, 25°C and maximum-power selections. AUTOTERM Flow heaters The button starts pre-heating for two hours or continues pre-heating until it is switched off manually. The RGB LED shows operating state and level: blue for minimum, purple for low, green for medium, yellow for high and red for maximum. A flashing red LED indicates an error, while alternating red and blue indicates shutdown. What is included?

Frequently asked questions What is the difference between Mono and Duo? The Mono module connects the heater and Push Control button. The Duo module adds a third connection for a supported additional panel. Can this Mono controller work beside a Comfort Control? No. Choose the Duo version if you need both controllers on one heater. The separate panel wire alone cannot add the missing module port. Will it control an AUTOTERM Air 2D or Air 4D? Yes, AUTOTERM lists both current models as compatible. Confirm older heater versions separately before ordering. Does temperature control work without an external sensor? No. Air-heater temperature selections require a compatible external temperature sensor. Without one, the Push Control operates through power settings. Is the complete controller waterproof? No. The stainless push button is IP67 rated. The control module must remain in a dry, protected location. Can Select Caravans deliver it in Auckland and across New Zealand? Yes.
