Tempmaster Induction VAV

[mdp]

Anyone out there happen to have any information on the Tempmaster Type SP box circa 1969? Any help would be appreciated, I have an old building that's had too many incompetant fingers playing with it and making it "better".
Thanks

those were my first intro to VAV systems before the days of minimum cfm setpoints and VFDs that was back in the mid 80s.the most important thing i was shown and taught was the bladder bag wears itself and the smallest of pinholes due to expanding and bleeding is fixable.that the inlet duct must be 4X the diameter in leanght straight in...so that pickup tube can pick up a minimum .5" static to start the box to react right off.the stats get calibrated with a dywer guage 2" range at the box 1" at the stat checkout...the unit delievery from the unit should be 55F and ranging 1" to 1.5" on the staic setpoint IGVs or VFD controlled.always check the supply air into the supply trunks then work the box...the scooped air is either held and inflates the bladder or bleeds out the stat to deflate and cool the space.if i said common sense things don't take it to heart..........
