[BLDG-SIM] Mysterious space heating load spikes

[Brody Wilson]

Randal,
    I just ran into this issue myself, it looks like the temperature alarms
on your GSHP Water loop are alarming and shutting off your equipment, then
the loop returns to non alarm temps, then the equipment cycles back on, etc.
It looks like you're alarming on both the high and low sides, so I'm
guessing that whatever heat source or heat sink you have are too small. If
you have a ground source heat exchanger make it bigger and see if that fixes
it.

Let me know if that's it.
