TK-400
Universal Twinning and Paralleling Kit
Jackson Systems
The Jackson Systems TK-400 is designed to allow a single thermostat to control two separate HVAC units. The TK-400 can also be expanded to control a total of 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. Thermostats and HVAC units can be located up to 300 feet from the TK-400 panel.
FEATURES:
Only identical furnaces should be twinned in order to insure that both furnaces start at the same time.
*If furnaces are not identical, back draft dampers may be required.
