<div dir="ltr"><font face="Tahoma" color="#000000" size="2">Within the boiler property dialog box in Water-Side HVAC, the performance curve for HIR-FT shows f(t water entering, t water leaving) and while hoovering the moose over the input box the comment "Bi-Quadratic
Curve: the HIR-FT as a function of the temp of entering and exiting water (undefined)". Yet a click further to the item help page states "<font face="Times New Roman" size="3">...as a function of the supply temperature and the environmental temperature. "</font></font></div>
<div dir="ltr"><font face="times new roman"></font> </div>
<div dir="ltr"><font face="Tahoma" size="2">While I have completed a curve based on entering and exiting water temp and have seen expectable results using it, it has been said that this is inaccurate and the curve should reflect what is shown on the item help
page. If this is correct please detail the inputs needed to complete the HIR-FT curve. With no sight in mind, I would say the supply temp is 180F and the environment temperature is slightly above the building air conditioning setpoint temp at 75F-80F and
these numbers will be fairly constant which would not really yield a curve.</font></div>
