[Equest-users] eQuest - first-time - baseboard heat with HRV

[Carol Gardner]

Derek,

Probably the best way to do this is to create a dummy space - very small 
area, volume, etc., a dummy zone, with very small, as many zeros as you 
can fit,  fan kW/cfm, zero out the cooling and heating capacity, and put 
your OA cfm in it as the design cfm. Then when you are your real zones 
specify your Outside Air From System dummy zone, using whatever name you 
give it. The only other possible problem you might have depends on what 
system you specify your baseboard heaters as. I think you could specify 
them as PSZ and do the same thing with your kW/cfm in it so you have 
virtually no fan energy, zero out your cooling capacity, and put your 
heaters in as baseboards.

Try this and let me know if you have any further problems.
