Dual fuel controller for Mitsubishi heat pumps

Last fall I had Mitsubishi heat pumps installed for air conditioning and efficient heat, complementing an existing 3-zone modern Bosch greenstar hydronic baseboard propane boiler system. In the winter, I primarily use the heat pumps for heating, but when the temperatures get below 10F, I would like to automatically switch from the heat pumps to the boiler.

What are thoughts on the easiest way to accomplish this?

One of my Mitsubishi units already has the MRCH1/MIFH1 RedLINK remote control system If I upgraded all the Mitsubishi controls to RedLINK controls, could I use something like a Honeywell HZ432 panel to manage the system?

Thanks for your experience.
