Greetings-
I have set up PVAV systems with hot water coils. I am getting error messages (See Below) for each of my systems. On the LS-S reports, heating capacity for unit and zones is zero, but I do have hot water coils and a boiler loop, etc.
See below,
Thansk,

**WARNING**********************************************************************
ZONE EL1 NE Perim Zn (G.NE2)
might have insufficient heating capability.
Check that the SYSTEM or ZONE HEATING-CAPACITY plus this
ZONEs BASEBOARD-RATING is adequate to maintain the ZONE
specified DESIGN-HEAT-T for the calculated peak ZONE load
(see LS-A or LS-B for the ZONE peak load.)
SYSTEM HVAC-1
which supplies the above listed ZONE, has a design heating
coil exit temperature, HEAT-SET-T,(plus any zone reheat)
below its MAX-SUPPLY-T or the ZONE DESIGN-HEAT-T, which
might account for the insufficient heating capability.
**WARNING**********************************************************************
ZONE EL4 East Perim Zn (G.E2)
might have insufficient heating capability.
Check that the SYSTEM or ZONE HEATING-CAPACITY plus this
ZONEs BASEBOARD-RATING is adequate to maintain the ZONE
specified DESIGN-HEAT-T for the calculated peak ZONE load
(see LS-A or LS-B for the ZONE peak load.)
SYSTEM HVAC-1
which supplies the above listed ZONE, has a design heating
coil exit temperature, HEAT-SET-T,(plus any zone reheat)
below its MAX-SUPPLY-T or the ZONE DESIGN-HEAT-T, which
might account for the insufficient heating capability.
**WARNING**********************************************************************
PREHEAT/HEATING-CAPACITY in SYSTEM HVAC-1
is too low to provide the requested supply temperature for
the calculated mixed air temperature using total ZONE loads
(on LS-A/B) and SYSTEM design parameters, plus outside air
conditions (on LS-C), and specified capacities & air flows.
Requested temperature is 55.00 calculated is -3.14
Check HEATING-CAPACITY, HEAT-SET-T, PRE-HEAT-T, MAX-SUPPLY-T,
DESIGN-HEAT-T, and ZONE loads for consistency.
