iO TWIN: Universal Twinning/Paralleling Kit

The iO TWIN is a universal Twinning/Paralleling Kit that is designed to allow a single thermostat to control multiple HVAC units. It represents a very affordable twinning solution that greatly reduces installation time for the contractor.

The iO TWIN  can be applied where multiple HVAC units are used to condition large spaces such as church sanctuaries, fellowship halls, recreation areas, warehouses and manufacturing facilities as well as other applications where large packaged RTUs cannot be applied due to roof pitch and load restrictions. The Twinning Kit can be applied to HVAC units sharing common or separate supply and return ducts.

The iO-TWIN was engineered to incorporate solid-state, diode relay logic with all components and wiring terminals mounted on a single, compact, printed circuit board. The PC board is mounted on a Snap Track base to facilitate ease of installation.

The Twinning Kit can be used with single stage (1 heat / 1 cool), multi-stage (2 heat / 2 cool) and heat pump (3 heat / 2 cool) equipment. Standard 18 gauge thermostat wire is required for the HVAC units and thermostat that can be located up to 300 feet from the panel. When used in a single panel array, the iO TWIN  can control two HVAC units. Two iO TWIN panels can be twinned together to control four units from a single thermostat.

Ease of Installation
The iO TWIN  saves hours of installation time by incorporating dedicated terminals for all system wiring. Only standard 18 gauge thermostat wire is required. The panel can be mounted in the most convenient location up to 300 feet from the HVAC units and controlling thermostat. LEDs provide visual confirmation of equipment mode of operation, fan, reversing valve (heat pump only) and staging status which simplifies servicing of the system. The panel does not require any system setup. A separate 24 volt, 40VA transformer provides power for the panel and controlling thermostat. When used with fossil fuel furnaces sharing a common supply duct, back draft dampers are required and the controlling thermostat must be equipment compatible.

Competitive Difference
The iO TWIN is compatible with both heat / cool and heat pump equipment with no special setup required. The iO TWIN can be expanded to control up to four HVAC units from a single thermostat. A separate 24 volt transformer provides power for the panel and thermostat which isolates the twinning kit from equipment transformers thus eliminating transformer phase problems. Status LEDs provide visual confirmation of system functions which simplifies service and diagnostics.

Installation & Service Benefits
The iO TWIN  has clearly labeled dedicated terminal blocks for HVAC equipment, thermostat and transformer wiring. Only standard 18 gauge thermostat wire is required. LED status indication simplifies test, check and startup as well as service diagnostics.
