Responding to the question on 424.3
ASSE 1016 requires
control valves to protect against temp. fluctuations of + or –
3degr. of the selected temp.
ASSE 1017 limits
the temp. of the mixing valve to 120 degr. F. There are three
types of valves available.
1)Pressure balancing,
2)thermostatic, and
3)combination thermostatic pressure-balancing.
1)
would comply with ASSE1016 and the temp. could be set at any
min or max. limited only by the settings . 2)
would comply with ASSE 1017 and would internally by set at 120 degr.
3)
is internally set at 120 degr. but has a fluctuation of + or – 3
degr. Tom Connable, Plans Examiner, Shelby County Code Enf.
