3.  Functional Testing Procedure

a. CHW System with Bridge Tender

Step / Mode / Test Procedure / Expected Response / Pass (Y/N/
N/A) /
1 / Pump(s) Off / Standby check. HOA in Auto position(s). Pump(s) commanded Off by BMS. / Verify by visual inspection that:
a)  Pump(s) are off, zero flow.
b)  Bridge-Tender valves V-1 and V-2 are closed.
2 / Pump P-1 Startup / HOA in Auto position. Pump commanded On by BMS. / Verify by visual inspection that:
a)  Bridge-Tender valve V-1 (return pipe) opens.
b)  Pump, P-1, is On, other pumps are Off.
c)  Bridge-Tender valve V-2 (bypass) throttles.
3 / Pump P-1 Operation / HOA in Auto position.
Pump and Bridge-Tender Verification: AHU supply air (SA) discharge setpoints at initial value 55F as a group. Through BMS raise/lower setpoints per schedule record table. / Verify by local and remote reading that:
Pump P-1 status is On, all other pump status’ are Off, B-T valves modulate allowing blending of SCHW based on change in AHU setpoints. BMS readings, local B-T panels readings and local instrument readings correspond.
4 / HOA Operation / HOA in Auto position. Move HOA switch to Off position for all pumps. Command P-1 On with HOA switch. Command P-1 Off with HOA switch. Repeat for all pumps. Reset pump, P-1, HOA switch to Auto, after start, place remaining pumps in Auto position. / All pumps turned Off by HOA switches. P-1 turns On, B-T valves modulate. When commanded by HOA switch, all other pumps turn On. After reset of pump, P-1, to Auto, P-1 starts. All other pumps remain Off.
5 / Pump P-2 Startup / HOA in Auto position. Pump, P-1, commanded Off by BMS, pump, P-2, commanded On by BMS. / Verify by visual inspection that:
a)  Bridge-Tender valve V-1 (return pipe) opens.
b)  Pump, P-2, is On, other pumps are Off.
c)  Bridge-Tender valve V-2 (bypass) throttles.
6 / Pump P-2 Operation / HOA in Auto position.
Pump and Bridge-Tender Verification: AHU supply air (SA) discharge setpoints at initial value 55F as a group. Through BMS raise/lower setpoints per schedule record table. / Verify by local and remote reading that:
Pump P-2 status is On, all other pump status’ are Off, B-T valves modulate allowing blending of SCHW based on change in AHU setpoints. BMS readings, local B-T panels readings and local instrument readings correspond.
7 / Automatic Start upon Power Failure / HOA in Auto position. Pump, P-2, local disconnect moved to Off position (simulating power failure to pump, P-2). After pump, P-1, starts, restore power to pump, P-2. / Pump, P-2, is Off. Pump, P-1, starts automatically. B-T valves modulate. Pump, P-1, continues to run, pump, P-2, remains Off.

b.  CHW System without Bridge Tender

Step / Mode / Test Procedure / Expected Response / Pass (Y/N/
N/A)
1 / Pump(s) Off / Standby check. HOA in Auto position(s). Pump(s) commanded Off by BMS. / Verify by visual inspection that pump(s) are off, zero flow.
2 / Pump P-1 Startup / HOA in Auto position. Pump commanded On by BMS. / Verify by visual inspection that Pump, P-1, is On, other pumps are Off.
3 / Pump P-1 Operation / HOA in Auto position.
Pump Verification: AHU supply air (SA) discharge setpoints at initial value 55F as a group. Through BMS raise/lower setpoints per schedule record table. / Verify by local and remote reading that:
Pump P-1 status is On, all other pump status’ are Off, BMS readings and local instrument readings correspond.
4 / HOA Operation / HOA in Auto position. Move HOA switch to Off position for all pumps. Command P-1 On with HOA switch. Command P-1 Off with HOA switch. Repeat for all pumps. Reset pump, P-1, HOA switch to Auto, after start, place remaining pumps in Auto position. / All pumps turned Off by HOA switches. P-1 turns On. When commanded by HOA switch, all other pumps turn On. After reset of pump, P-1, to Auto, P-1 starts. All other pumps remain Off.
5 / Pump P-2 Startup / HOA in Auto position. Pump, P-1, commanded Off by BMS, pump, P-2, commanded On by BMS. / Verify by visual inspection that pump, P-2, is On, other pumps are Off.
6 / Pump P-2 Operation / HOA in Auto position.
Pump Verification: AHU supply air (SA) discharge setpoints at initial value 55F as a group. Through BMS raise/lower setpoints per schedule record table. / Verify by local and remote reading that:
Pump P-2 status is On, all other pump status’ are Off, BMS readings and local instrument readings correspond.
7 / Automatic Start upon Power Failure / HOA in Auto position. Pump, P-2, local disconnect moved to Off position (simulating power failure to pump, P-2). After pump, P-1, starts, restore power to pump, P-2. / Pump, P-2, is Off. Pump, P-1, starts automatically. Pump, P-1, continues to run, pump, P-2, remains Off.
