Equipment *Suction and discharge of fans.
*Inlet side of mixing boxes.
*Pump return for hot and chilled
*Each zone of multizone hot and

184.108.40.206 Combination Instrument and Controls. Recording and
indicating instruments shall be combined with control devices to
measure conditions at the point of control.
220.127.116.11 Multi-Point Remote Indicators. Use multi-point remote
indicators to check temperature, pressure, humidity, and other
equipment operating conditions for areas remotely located from
the central control point. With large installation, it can be
advantageous and economical to provide multi-point remote
indicators at a central supervisory location instead of having
several indicating type instruments installed at different
Control Board. Instruments and controls in one space
shall be combined on a single control board and arranged for
rapid readout. Locate control boards for walk-up access.
that under normal operating conditions, the indicating pointer
will remain vertical. Variations in operating conditions shall
occur within the middle one-third of the range.
b) Compensation. Specify self-compensating
instruments which are not affected by external changes in
temperature or pressure. Provide surge protection for pressure
