Universal Twinning Kit

Universal twinning and paralleling of HVAC equipment made simple

Up until recently, twinning or paralleling of multiple HVAC units has been a wiring nightmare for contractors. Now Jackson Systems offers the TK-400 Universal Twinning and Paralleling Kit that is design to allow a single thermostat to control two or even four HVAC units. The TK-400 can be used on common or separate ducted systems with single stage (1 heat / 1 cool), multi-stage (2 heat / 2 cool) and heat pump (3 heat / 2 cool) equipment. Only standard 18 gauge thermostat wire is required and thermostats and equipment can be located up to 300 feet from the TK-400 panel. When HVAC units share a common return and supply duct, backdraft dampers should be installed and thermostat fan operation must be set for electric. The TK-400 greatly reduces installation time and costs far less than other twinning kits on the market. More information on the TK-400 is available on the Jackson Systems website at www.jacksonsystems.com.
