All rights reserved. Form No. CD-BZ-A 12 METHOD OF OPERATION States: Virgin State - The ZIP Economizer comes shipped from the factory in this state. When "Setup Incomplete" is displayed, no control will occur until setup is completed. Automatic State — All of the following strategies and operational modes are available in this state. A minimum of two pieces of information (in level 2 Settings MENU) must be entered before the ZIP Economizer will go into Automatic State: 1. The appropriate ZIP code must be entered. 2. The minimum damper position set point (Vent Min Pos) percentage must be entered. When in Automatic State, the G input terminal is used to monitor a Thermostat Occupancy Output, Time -clock or Indoor Fan Signal. When the G terminal is energized, the ZIP Economizer will operate in Occupied (damper will move to the proper ventilation position). Otherwise, the ZIP Economizer will operate in Unoccupied. Important: Operation from a Thermostat Fan Signal does not meet Occupancy Code Requirements. Strategies: Compressor Protection and Energy Savings DXLL (Supply Air Low Temperature Protection in Mechanical Cooling). This strategy is activated automatically when in Mechanical Cooling Mode depending on supply air temperature. Timers, temperature dead bands and SAT Y2 Limit setting all interact with this strategy. • IF SAT is less than 45°F THEN all compressor stages are disabled. • IF SAT is greater than or equal to 45°F AND less than 47°F THEN Compressor stages may or may not be enabled based on whether or not SAT is rising or falling. • IF SAT is greater than or equal to 47°F AND SAT Y2 limit is OFF THEN both compressor stages are enabled • IF SAT is greater than or equal to 47°F AND less than 56.5°F AND SAT Y2 limit is ON THEN ls' stage compressor is enabled and 2nd stage compressor is disabled. • IF SAT is greater than or equal to 56.5°F THEN both compressor stages are enabled. SAT Y2 Limit This strategy inhibits the 2nd stage compressor from coming on prematurely based on SAT temperature and time. • IF Y2 is energized AND Compressor 1 has been running for less than 4 minutes AND Supply Air Temp is less than or equal to its required set point +1.5° (56.5°F) THEN Compressor 2 will not be allowed to come on. LCLO (Low Ambient Compressor Lockout) This strategy inhibits compressor operation at low outdoor air temperatures. • IF OAT falls below the low limit (50°F) AND not in Heat Pump Mode THEN Compressor 1 and Compressor 2 will be disabled. • IF OAT rises 2°F above the Low Limit (52°F) OR in Heat Pump Mode THEN Compressor 1 and Compressor 2 will be enabled. Minimum On/Off Time This strategy prevents the compressors from "short -cycling". • IF any Compressor is energized it run it at least 180 seconds EXCEPT when entering Brownout Mode when compressors will be shut off immediately. • IF any Compressor is de -energized it will be kept off for at least 180 seconds. No Simultaneous ON/OFF On RTUs with 2 compressors this strategy is used to prevent both compressors from coming on at the same instant to keep electrical demand down. • Compressors 1 & 2 are kept from switching on together by a 10 second time delay. • If SAT Y2 Limit is set to "On" compressor 2 is delayed by 240 seconds to evaluate if the single compressor already operating can bring SAT less than or equal to set point +1.5 °F (56.57). • Compressors 1 & 2 are kept from switching off together by a 5 second time delay EXCEPT when entering Brownout when compressors will be shut off immediately. Brownout Protection Input power (24Vac) is monitored. • IF input voltage drops to 75% AND it stays there for 30 seconds THEN Brownout will be enabled. • IF input voltage rises to 85% AND it stays there for 300 seconds THEN Brownout will be disabled. Under Brownout conditions the current operating mode will be maintained EXCEPT Mechanical Cooling and Manufacturer reserves the right to discontinue , or change at any time, specifications. design and prices without notice and without incurring obligations.

Instead of Mechanical Cooling it will go to Ventilation, DCV or Unoccupied. Instead of Integrated Cooling it will go to Free Cooling. This strategy prevents compressor operation during Brownout conditions. Compressors will be turned off immediately (bypassing Minimum ON/OFF Timers). Random On Delay after Power Up After a Power Blackout or any Power Restore, compressors will go through a random time delay before allowing them to operate. This Random Timer is between 30-180 seconds. This helps the electrical network to come back up without excessive demand from multiple RTUs and compressors coming back on after the Blackout. High Limit Changeover Note: Economizing is enabled based on one of the following four options, and becomes active in Free Cooling and Integrated Cooling. Single Dry Bulb Changeover If only an OAT Sensor is connected, it will be analyzed against the reference Outdoor Air Changeover Temperature Value (based on entered ZIP code). • IF OAT is 2°F below the reference value THEN economizing will be enabled. • IF OAT is above the reference value THEN economizing will be disabled. Differential Dry Bulb Changeover Must have OAT and RAT Sensors connected. OAT and RAT will be analyzed against each other and the OAT will be analyzed against the reference Differential Temperature High Limit (DTHL) (based on entered ZIP code). • IF OAT is 2-8°F below the RAT (Value Climate Zone Dependent) AND OAT is 2°F below the reference DTHL THEN economizing will be enabled. • IF OAT is greater than or equal to 0-6°F below the RAT (Value Climate Zone Dependent) OR the OAT is greater than the reference DTHL THEN economizing will be disabled. Single Enthalpy Changeover Must have OAH (RH) and OAT Sensors connected. Outdoor Air Enthalpy will be calculated. They will be analyzed against the reference values as follows: • IF Outdoor Enthalpy is 2 btu/Ib less than the reference Enthal- py High Limit (ETHL) (default is 28 btu/Ib — 2 btu/Ib = 26 btu/Ib) AND OAT is 2°F below the reference ETHL (based on entered ZIP code) THEN economizing will be enabled. • IF Outdoor Enthalpy is greater than reference ETHL (default is 28 btu/Ib) OR OAT is greater than the reference Temperature High Limit ETHL (based on entered ZIP code) THEN economizing will be disabled. Differential Enthalpy Changeover Must have OAH, OAT, RAH and RAT Sensors connected. Outdoor Air Enthalpy and Return Air Enthalpy will be calculated. • IF Outdoor Enthalpy is 2.5 btu/Ib less than Return Air Enthalpy AND Outdoor Enthalpy is 2 btu/Ib less than the reference Differential Enthalpy High Limit (DEHL) (30 btu/Ib) AND OAT is 2°F below the reference DTHL (based on entered ZIP code) THEN economizing will be enabled. • IF OutdoorAir Enthalpy is 1 btu/Ib less than Return Air Enthalpy OR Outdoor Air Enthalpy is greater than reference DEHL (30 btu/Ib) OR OAT is greater than reference DTHL (based on entered ZIP code) THEN economizing will be disabled. Operational Modes: Free Cooling Outdoor Air Ambient conditions are analyzed by one of the 4 Changeover Strategies above (Single or Differential Dry Bulb; Single or Differential Enthalpy) and has been deemed suitable for "free" cooling. • Y1 is energized indicating a call for stage 1 cooling. • Y2 is de -energized. • W1 is de -energized. • G input could be energized or de -energized (occupied or unoccupied state). • Compressor 1 is off'. • Compressor 2 is off'. • Indoor Fan is on Low Speed. • Exhaust Fan could be running or not based on % damper open position'. • Damper Position output is modulated between the respective current Minimum Damper Position Set Point and 100% open to attempt to maintain SAT set point (55°F). When OAT is at 55°F the damper will be fully open to outside air. As outdoor air continues to rise above 55°F, SAT will rise with it.

Note: In theory, if Exh Fan On Pos/Low Exh Fan Pos for damper % is set very low, then Exhaust Fan could also run in other modes (Ventilation, Mechanical, DCV). Control of the Exhaust Fan is damper position dependent. Damper set point for enable/disable of the Exhaust Fan is Indoor Fan Speed dependent (High Speed Damper Set point = Exh Fan On Pos; Low Speed Damper Set point = Low Exh Fan Pos). • IF Damper Pos is 10% greater than Exh Fan On Pos/Low Exh Fan Pos OR Damper Pos is 100% open THEN Exhaust Fan will be energized. • IF Damper Pos is 10% less than Exh Fan On Pos/Low Exh Fan Pos OR Damper Pos is less than 5% open THEN Exhaust Fan will be de -energized. Example: If Exh Fan On Pos is set at 45%, when damper opens to 55%, exhaust fan will turn on. When damper closes to 35%, exhaust fan will turn off. Service and Commissioning Manual Mode This menu is available after Setup has been completed. This is selected in Level 2 menu Service and Commissioning. This supports the commissioning phase allowing all connected RTU components (except for the room thermostat) to be tested by manually commanding them through the keypad interface.

Return to Automatic will occur automatically between 1-8 hours (adjustable) unless Return to Automatic is selected. Note: Damper will move at high speed. Note: Compressors, Exhaust Fanl and Indoor 2-Speed fan' minimum on or minimum off time does NOT apply in this test state. They will be turned on and off immediately based on the entered command. Also, Exhaust Fan' will not be turned on automatically based on damper position in this mode, but it can be manually commanded. Damper Scaling If there was a mechanical failure or adjustment that prevented proper damper scaling from virgin to automatic, it can be rescaled. "Damper scaling starts in 10 secs" and will countdown to 0. A message will scroll saying "Damper scaling for better operation. If obstruction is present rescale damper in commissioning menu". (For detailed instructions on this — please see the section "Service and Commissioning." This will open damper to 100% (re -scale control signal if needed). Note: failure to identify obstructions or improper setup of damper assembly may result in an improper scaling and operation of the damper. Once scaling is complete, a message will appear saying "Damper scaling successful'. The ZIP will then show "maximum at XX° _ 100W That message will show maximum rotation of the damper. This process ensures the damper is always operating and displayed from 0-100%. Acceptance Test (Four possible options) This menu is available after Setup has been completed. This complies with the California Title 24 Mechanical Testing and has four tests. To prevent RTU safety lockout and possible equipment damage, ensure the RTU indoor fan is running! Economizer Test (NA7.5.4) This is an automatic functional and verification test that moves the damper 100% open/100% closed/and Minimum Position and switches on CC1 and EF1 (if available). It leads one through the test step by step in accordance with California Title 24 test form. Note: 1 minute minimum on time; 1 minute minimum off time for compressor applies in this test to prevent damage from short cycling. Exhaust fan' does turn on based on damper position in this test. Note: Damper will move at high speed. Ventilation Test (NA7.5.1.2) This is a manual test that allows adjustment to the damper minimum position (Vent Min Pos) in the Settings menu for verification of ventilation rates. Note: Damper minimum position must be commanded to get damper to go to minimum position in this mode! Example: Prior to going into this test, let's say Vent Min Pos is set for 20%. After going into this test you still must go into Settings/Vent Min Pos and change the value by at least 1%, then you can change back to 20%. If you don't create a change of value for Vent Min Pos the damper will not move off fully closed position in this test. The new Vent Min Pos setting you enter will be stored and used when you return to automatic. RTU Test (NA7.5.2) This is a manual test used to test the following signals from the thermostat to the RTU: • G powered (Occupied) — damper is at minimum position (Vent Min Pos); otherwise the damper goes closed to outdoor air (Unoccupied). • Y1 powered — CC1 is energized; otherwise CC1 is de - energized. • Y2 powered — CC2 is energized; otherwise CC2 is de - energized. Note: 1 minute minimum on time; 1 minute minimum off time applies in this test mode to prevent damage from short cycling compressors. • W1 powered — Heating is enabled DCV' Test (NA7.5.5)3 This is a manual test used for the following CO2 input will be used to modulate minimum damper position between DCV Min Pos and Vent Min Pos as CO2 levels vary below and above (respectively) the CO2 Set point. All of the above tests can be aborted by selecting Return to Automatic in the Level 2 menu. Notes: ' Only available with Energy Module Option. If no Energy Module exists associated menu options will not be displayed. 2 Subject to Compressor Protection Strategies as noted earlier. 3 "G" must be energized to run test. g o I For additional technical information on this product go to: ff, .o http://www.zipeconomizer.com Manufacturer reserves the right to discontinue , or change at any time, specifications. design and prices without notice and without incurring obligations.
