Replace thermostat for GE Weathertron heat pump

Hi all,

I have a GE Weathertron heat pump (with A/C + backed by an oil furnace) for which I want to replace the existing thermostat. The thermostat has the following terminals:

O R T M G Y X2 B W

My problem is that I can't find any information about what the "M" terminal
is used for. I purchased a Honeywell programmable thermostat but their customer support never heard of a "M" terminal/wire.

Anyone got a idea?
