the equipment being connected. Verify exact location and elevations at work site prior
to any rough in work. DO NOT SCALE PLANS. If field conditions, details, changes
in equipment or shop drawing information require a significant change to the original
documents, contact the owners representative for approval before proceeding.

Mechanical and electrical drawings show design arrangement only for Diffusers,
grilles, registers, air terminals, lighting fixtures, sprinklers, speakers and other
items. Do not rough-in contract work without reflected ceiling location plans.
2. Before roughing for equipment furnished by Owner or in other contracts, obtain
from Architect and other Contractors, approved roughing drawings giving exact
location for each piece of equipment. Do not "rough in" services without final
layout drawings approved for construction. Cooperate with other trades to
insure proper location and size of connections to insure proper functioning of all
systems and equipment. Obtain written authorization from the Owners
representative or other contractor for any “rough ins” that, due to project

preference except where grading of piping becomes a problem, followed by
piping then electrical wiring. If, after installation of any equipment, piping,
ducts, conduit, and boxes, it is determined that ample maintenance and passage
space has not been provided, rearrange work and/or furnish other equipment as
required for ample maintenance space. Any changes in the size or location of
the material or equipment supplied, which may be necessary in order to meet
field conditions or in order to avoid conflicts between trades, shall be brought to
the immediate attention of the Owner's Representative and approval received

Test or Check Test
Method
Seasonal
Test
A random sample of up to 5% of the TAB report data shall be selected for
verification (air velocity, air or water flow rate, pressure differential, electrical or
sound measurement, etc.). The original TAB contractor will execute the checks,
witnessed by the commissioning authority. The TAB contractor will use the same
test instruments as used in the original TAB work.
A failure4 of more than 10% of the selected items of a given system5 shall result in
the failure of acceptance of the system TAB report and the TAB contractor shall be
responsible to rebalance the system, provide a new system TAB report and repeat
random verifications of the new TAB report.
The random testing will include the verification of minimum outdoor air intake
flows at minimum, maximum and intermediate total airflow rates for 100% of the
air handlers. Other selected data to be verified will be made known upon testing day
Demo
Verify that final settings of all valves, splitters, dampers and other adjustment
devices have been permanently marked by the TAB Contractor.

4 Failure of an item is defined as follows: For air flow of supply and return: a deviation of more than 10% of instrument reading For minimum outside air flow: 20% of instrument reading (30% for reading at intermediate supply flow for inlet vane or VFD OSA compensation
system using linear proportional control)
For temperatures: a deviation of more than 1F For air and water pressures: a deviation of more than 10% of full scale of test instrument reading For sound pressures: a deviation of more than 3 decibels. (Variations in background noise must be considered)
5 Examples of a “system” are: the air distribution system served by one air handler or the hydronic chilled water supply system served by a chiller or the
condenser water system. Systems can be defined smaller if inaccuracies in TAB work within the smaller defined system will have little or no impact on
connected systems.

(3) Individual method (recommended for Heat Recovery Systems)
(a) Changeover evaluated by room temperature and
setpoints of the individual indoor unit group in the
changeover group
(b) Changeover affects individual indoor unit group in the
changeover group
(4) Average method
(a) Changeover evaluated by the average of all indoor unit
group’s room temperatures and setpoints operating in
Cool, Heat, or Auto mode in the changeover group list
(b) If none of the indoor units in the group meet the above
requirements the Fixed method of changeover will be

based upon the difference between the room temperature
and cooling setpoint. If the room temperature falls below
the primary cool changeover point (cool setpoint plus the
primary changeover deadband) the cooling demand is
considered as 0 (zero). Then the total cooling demand is
calculated as the sum of each indoor unit’s cooling
demand
(b) The opposite is true for the total heating demand

(d) The weight 0 (zero) means the indoor unit’s demand is
not added in the total demand, so the indoor unit’s
demand is considered to be 0 (zero)
(e) The weight 2 or 3 means the indoor unit’s demand is
added 2 or 3 times in the total demand, respectively
(f) Changeover to cooling mode shall occur when the total
cooling demand is greater than the total heating demand.
(g) The opposite is true for changeover to heating
(h) Vote supports a Heating Override option, which
prioritizes switching to the heating mode if at least one
room temperature falls below the secondary heat
changeover point (heat setpoint minus the secondary
changeover deadband) even if the total cooling demand
is greater than the total heating demand.
(i) Changeover affects all indoor unit groups in the
changeover group.
(6) Changeover shall change the operation mode of the indoor unit
that is set as the Changeover Master. The Changeover Master
indoor unit shall then change the operation mode of all indoor
unit groups daisy chained to the same outdoor unit in the Heat
Pump system or branch selector box in the Heat Recovery
system.
(7) Guard timer
(a) Upon changeover, guard timer will prevent another
changeover during the guard timer activation period (15,
30, 60 (default) min).
(b) Guard timer is ignored by a change of setpoint manually
