The IO HVAC CONTROLS iO-TWIN-TR universal twinning kit allows a single thermostat to manage two separate HVAC units and can expand to control up to four. Compatible with common or separate ducted systems using single-stage, multi-stage, and heat pump equipment. Standard 18-gauge thermostat wire is required, with a range of up to 300 feet from the panel.
This twinning kit includes a 20VA transformer and reduces installation time and cost. It can also be used with the Lead/Lag Controller.
We pulled together the parts most installs need for this unit, plus a few add-ons worth a look. Check what you need — nothing here blocks checkout.
