Delay to wait for reversing valve to change over. When changing
Reversing between heat and cool, the thermostat will turn off the
Valve Delay compressor, then wait for MCOT. The thermostat will then change
(RVD) the state of the O/B signal, and wait for the reversing valve delay
(RVD) before turning the compressor and fan back on.
