Unit Nomenclature (Air Handler)

Notes:
1 – Air flow on the 050 unit in the horizontal configurations should be limited to 1900 cfm in cooling mode, or condensate blow off may occur.
2 – Compressor section mus t be matched with identical model SVH air handler section. See Compatibility Table
3 – To field convert the SVH to bottom flow air discharge. The SAHBCK kit must be ordered separately.
4 – UPC is not compatible with Symphony or IntelliZone2.

** VS Compressor speed is given for the factory default cfm settings. When the cfm default settings are changed it will change the relationship to the compressor speed that is shown in the table. In cooling mode compressor speeds 10-12 are only available when SuperBoost mode is selected at the thermostat.
Factory settings are at recommended G, L , H and Aux positions
“G” may be located anywhere within the airflow table.
“L” setting should be located within the boldface CFM range
“H” setting MUST be located within the shaded CFM range
“Aux” setting MUST be equal to or higher than factory setting shown in the table above CFM is controlled within 5% up to the maximum ESP

Line Set Sizes

NOTE: Manufacturer recommends the standard total line set length not to exceed 80 ft with no more than 25 ft of vertical separation between the compressor section and the air handler. For installations that exceed the standard range refer to the Long Line Set Application Guide AG2200EW for further installation requirements.

Notes: * The “Charge Amount with SVH Air Handler” column is based on the charge amount for a SVH Air Handler + Compressor Section/Split. Additional charge will need to be added accordingly for line set length. After charge is added, additional adjustments can be made to get appropriate subcooling and superheat measurements. Additional charge for R410A is 0.50 oz. per ft. for 3/8” and 1.0 oz. per ft. for 1/2” tube. Longer line sets will significantly reduce capacity and efficiency of the system as well as adversely effect the system reliability due to poor oil return.

Operating Limits

NOTE: Minimum/maximum limits are only for start-up conditions, and are meant for bringing the space up to occupancy temperature. Units are not designed to operate at the minimum/maximum conditions on a regular basis. The operating limits are dependent upon three primary factors: 1) water temperature, 2) return air temperature, and 3) ambient temperature. When any of the factors are at the minimum or maximum levels, the other two factors must be at the normal level for proper and reliable unit operation.

WARNING: Gray area represents antifreeze concentrations greater than 35% by weight and should be avoided due to the extreme performance penalty they represent.
Antifreeze Correction Example
Antifreeze solution is Propylene Glycol 20% by weight. Determine the corrected heating and cooling performance at 30°F and 90°F respectively as well as pressure drop at 30°F for a 033 operating at 100% capacity.
The corrected cooling capacity at 90°F would be: 30,500 Btu/h x 0.969 = 29,554 Btu/h
The corrected heating capacity at 30°F would be: 34,100 Btu/h x 0.913 = 31,133 Btu/h
The corrected pressure drop at 30°F and 11.5 gpm would be: 7.9 feet of head x 1.270 = 10.03 feet of head

Dual Power Supply Connections
If two separate circuits are used to supply power to the auxiliary heat kit, the Installer will need to verify that each leg of the auxiliary heat circuit breakers are wired from the power supply correctly in order for the electric heat kit to operate properly. This can be done by measuring the supply side voltage of the auxiliary heat circuit breakers. Put a voltmeter on the L2 side of Circuit Breaker One and on the L2 side of Circuit Breaker Two. The voltmeter should read approximately 0 volts. If the meter reads high voltage, the auxiliary heat breakers need to be rewired so that breakers in the auxiliary heat kit match the wiring of the Disconnect Panel breakers. Meaning, L1 and L2 from one breaker in the disconnect panel must L1 and L2 from one breaker in the disconnect panel must connect to L1 and L2 at one of the auxiliary heat circuit breakers and L1 and L2 from the other breaker in the disconnect panel must connect to L1 and L2 of the other auxiliary heat circuit breaker, making sure that the L1 and L2 from each disconnect breaker matches the L1 and L2 at each of the auxiliary heat breakers.

Zone Sensors can be wired in daisy chain as show or in a star or hybrid configuration. Maximum of 5 sensors per UPC. Maximum allowable load 210mA. See the UPC install manual for possible sensor combinations.
Each ZS sensor must have a unique address, but the addresses do not need to be sequential. Use the DIP switches on the back of the ZS sensor to set an address from 0 to 4. (0 is the factory default.) Each DIP switch has the value shown in the figure to the left. Turn on as many DIP switches as you need so that their total value equals the address.
