NOT required for regular use. Traditionally, the LAT/HPT sensors were required for temperature / equipment monitoring. The Infin- ity Zoning System does not require these because the User Interface algorithms will perform temperature and airflow man- agement without use of these sensors. If desired, one or both sensors may be used in monitoring leaving air temperature and / or indoor coil air temperature. Consideration and / or flexibility will now permit using one of these sensors in the return air duct giving the dealer an option to view both entering and leaving air temperature at the User Interface. If applied, connect sensors to the LAT / HPT terminals (See Fig. 9, System Wiring, for connection to Infinity Damper Control). LAT is monitored by both AC and HP systems. LAT and HPT are both monitored only in HP systems.

To install - Locate LAT sensor in main supply trunk after heating and cooling coil and before first branch. The LAT sensor is radiant shielded to prevent heat from affecting correct air temperature.

1.Drill a 1/4 inch hole at location in supply trunk where sensor will be installed.

2.Insert sensor in hole and use as a template to mark the 2 mounting holes.

3.Drill two 1/16 inch holes to accept No. 6 screws through pre-drilled holes in duct temperature sensor back plate.

4.Use two No. 6 sheet metal screws to mount duct temperature sensor to unit.

5.Connect sensor to 2-conductor wire using provided wire nuts.

The HPT sensor (in heat pump applications) measures the tem- perature of the air leaving the indoor coil. The sensor is installed downstream of the indoor coil but before the electric heaters. It can be installed through the wall of the fan coil or may be located entirely inside the fan coil near the blower inlet. Anchor firmly in place with cable ties so that it cannot interfere with the blower wheel (See Fig. 9).

LED INDICATORS — Under normal operation, the Yellow and Green LEDs will be on continuously (solid). If the Infinity Damper Control does not receive communications with the User Interface, the Green LED will not be on. If there are faults present, the Yellow LED indicator will blink a two-digit status code. The first digit will blink at a fast rate, the second at a slow rate.

STATUS CODE

DESCRIPTION

16 =

Communication Failure

24 =

Damper Fuse Failed

45 =

Board Failure

46 =

Low Input Voltage

FUSE — A 1-amp automotive type fuse is used to protect the Infinity Damper Control from over current on the damper drive outputs. If this fuse fails, damper wiring should be inspected for shorts. Also, no more than five damper motors should be con- nected to a single damper output. Fuse should always be replaced with an identical 3 amp automotive fuse.

Step 6—ADDITIONAL DAMPER CONTROL BOARD SETUP

If you have more than four zones, a second Infinity Damper Control must be used and both dip switch settings on the second board supporting zones 5 through 8 must be moved to the right. The ABCD bus connector must be wired between both Infinity Damper Controls.

Step 7—Transformer Requirements

The Infinity Zoning System has a lower power draw from the system transformer than previous controls. It also drives only 2 zone damper outputs at a time. As a result, up to 8 zones each with up to 5 dampers, plus a smart sensor, can be handled without increasing the size of the system transformer or adding a second zoning transformer.

Use of the transformer provided in the furnace or fan coil is recommended without change in all zoning applications except those having a System Access Module (SAM). The SAM requires a separate transformer.

For those who still want more transformer capacity, a 60 VA system transformer may be used in place of the supplied 40 VA part.

Step 8—System Start-Up

Follow the system start-up process outlined in the Infinity Zone Control Installation Instructions for details.
