Name	Type	Variability	Description/Comments
zhxTy	ZHXTY	Start of run	zhx type (cndtypes.def): LhSo, LhStH, ArSo, ArStH, ArStC, or (future) nv. testable bits: So = set output, StH, StC, St = set temp (both), Lh = local heat (coil in terminal, or baseboard), Ar = heat/cool with air from air handler.

Name	Type	Variability	Description/Comments
sp	TEMP	Start of hour	setpoint if heat xfer is tstat controlled (SETTMP), else unused (hourly variability)
spPri	number	Start of run	setpoint priority: low #'s used first if setpoints equal, so can eg peg air heat b4 using local heat.

Name	Type	Variability	Description/Comments
ui	TI	Start of run	terminal TU subscript if a term cap type
zi	TI	Start of run	zone ZNR subscript always -- for term cap or vent zhx. When stable, just use ownTi?
ai	TI	Start of run	0 or AH ss (subscript) of air handler supplying Ar zhx (copied from tu).

Name	Type	Variability	Description/Comments
xiLh	TI	Start of run	subscr of local heat ZHX for same terminal if any, else 0; not set for self.
xiArH	TI	Start of run	was xiHeat. subscr of air heat or air set output ZHX for same terminal, if any, else 0
xiArC	TI	Start of run	xiCool. subscr of air cool ZHX for same terminal, if any, else 0

Name	Type	Variability	Description/Comments
nxZhx4z	TI	Start of run	chain: 0 or subscript of next terminal zhx for this zone; 0?? if vent; head ZNR.zhx1.
nxZhxSt4z	TI	Start of hour	chain: 0 or ss of next SETTMP zhx for this zone; head ZNR.zhx1St; kept sorted on sp/pri at runtime.

nxZhx4a	TI	Start of run	chain: 0 or subscript of next terminal zhx for this air handler; head AH.zhx1.

Name	Type	Variability	Description/Comments
mda	number	Start of hour	for SETTMP, mode (mdSeq[] subscr) in which this is active (ctrl'd by its sp) ZHX. in lower modes, heat is max, cool min; vica versa in hier modes.
