Hydronic System Controls <br /> For hydronic system pump motors z 7.5 hp,indicate method of variable flow control(VSD or <br /> C403.2.13 Variable flow control- equivalent method that requires z 30%design wattage at 50%design fluid flow);note <br /> C403.4.2.7 hydronic system pumps exception taken <br /> Identify whether hydronic coils have DDC controls and associated manner of pump speed <br /> control(differential pressure,zone hydronic demand,etc) <br /> For boilers that provide building heating,indicate controls that provide heating water <br /> temperature setback based on outdoor

upon demand;or exception taken. u <br /> 0403.4.2.4 and part load controls If system pump motor hp z 3 hp,also indicate controls automatically reduce flow by z 50% <br /> For chilled water systems(z 300,000 Btu/h,pump motor hp>_3 hp)that serve water-cooled <br /> unitary air conditioners,indicate VSD or staged pumps in chilled water system and heat <br /> rejection loop that reduce pump flow so that one control valve is nearly wide open,or to <br /> maintain a minimum differential pressure;or exception taken <br /> 0403.4.2 Boiler sequencing Indicate automatic controls that sequence operation of multiple boilers <br /> 0403.4.6 Hot gas bypass limitation For cooling equipment with hot gas bypass,provide either multiple step unloading or <br /> continuous capacity modulation;indicate bypass capacity per Table 0403.4.6 <br /> 0403.4.2.2 Two-pipe changeover Indicate changeover deadband(min 15°F),heating/cooling mode scheduling and <br /> systems changeover temperature range(limit 30°F) <br /> 0403.4.2.6 Chiller/boiler plant pump Indicate controls are configured to automatically reduce overall plant flow and shut-off flow <br /> isolation through individual chillers and boilers when not in use <br /> For cooling towers with fan motors z 7.5 hp,indicate VSD and method to adjust fan speed <br /> 0403.2.13.1.1 Heat rejection equipment- (adjusted

with VSD,indicate controls that ramp all fans in <br /> unison <br /> C403.4.3.3 Heat rejection equipment- Indicate open-circuit cooling towers with multiple pumps or VSD control are designed so all <br /> cooling tower flow turndown cells can be run in parallel <br /> C403.4.2.3.1 Water loop heat pump- Indicate capability of central equipment to provide minimum 20°F water supply temperature <br /> deadband deadband between heat rejection and heat addition modes;or exception taken <br /> Water loop heat pump- Indicate type of cooling tower(open-or closed-circuit)in equipment schedule;indicate method <br /> 0403.4.2.3.2.1 heat rejection equipment, used to limit system heat loss when heat rejection is not needed <br /> Zone 4 <br /> Water loop heat pump- For open-or closed-circuit cooling towers,provide a heat exchanger that separates the cooling <br /> 0403.4.2.3.2.2 heat rejection equipment, tower and heat pump loop <br /> Zone 5 <br /> 0403.4.2.3.3 Water loop heat pump- For hydronic
