What does a twinning kit do?
What does a twinning kit do?
The twinning kit is designed to allow a single thermostat to control two separate HVAC units. It can also be expanded to control a total of four HVAC units. The twinning kit can be used on common or separate ducted systems with single-stage, multi-stage and heat pump equipment.
What is a furnace twinning kit?
The Furnace Twinning Kit (FTK) provides the means for two (2) Amana® brand or Goodman® brand gas furnaces containing an Integrated Ignition control to operate at the same time from a single thermostat. The furnaces may deliver different CFMs in the cooling mode, if appropriate.
How does furnace twinning work?
When furnaces are twinned, the combined blower capacity is only 85% of the total CFM produced by the 2 blowers. By running a single wire between the twin terminal on each board and running a wire between the “C” or common terminal on each board, the furnaces are now twinned and will operate in unison.
Can you vent two furnaces together?
A solid-fuel-burning appliance or fireplace shall not connect to a chimney passageway venting another appliance. In other words, only one appliance per flue, period. It goes without saying, I hope, that gas or oil appliances cannot be vented into a flue which also vents a solid fuel appliance.
Can you twin ECM furnaces?
Twinning – Standard ECM Gas Furnace Twinning is defined as two identical model residential gas furnaces connected to a common duct system. We strongly recommend the heating and cooling equipment is always properly sized based on an acceptable heat loss/gain load calculation.
What is a twinning wire?
On our furnaces, twinning is made easy without any additional controls. On each board is a terminal marked “twin”. By running a single wire between the twin terminal on each board and running a wire between the “C” or common terminal on each board, the furnaces are now twinned and will operate in unison.
Can a gas furnace be vented horizontally?
Direct Vents These furnace vents can be installed horizontally through an exterior wall, or vertically so exhaust fumes go out through the roof. Although more costly than a natural vent, a direct vent is also a more efficient and safer option.
What is Category II venting?
Gas appliances are divided into four venting categories based on vent operating pressure and whether they are condensing or non-condensing. Category II is negative pressure, condensing. Category III is positive pressure, non-condensing. Category IV is positive pressure, condensing.
Can you twin variable speed furnaces?
Remember, variable speed furnaces cannot be twinned! A relay is suggested for twinning.
How do two thermostats work together?
When multiple thermostats control one system, the house is divided into zones using dampers in the ductwork throughout the house. When one zone needs heating or cooling, the damper for the ductwork in that zone opens, guiding the warm or cool air to that zone.
