INSPECTION
The following table details the parts included in this kit. Examine the kit
to ensure all parts are present.
LIMITATIONS
The primary function of the thermostat is to command a system contain-
ing communicating products.
The following are exceptions:
• Installing a communicating variable speed modulating furnace with
a non-communicating air conditioner. In this case, the variable-
speed modulating furnace relays 24 VAC outputs to the non-com-
municating air conditioner (per communicated commands by the
thermostat).
• Installing communicating controls in non-communicating Ducted
Systems products
• Installing a communicating interface control (which converts com-
municating commands into 24 VAC outputs)
CONVENTIONAL COMPATIBILITY CHECK
The Hx™3 Touch Screen Thermostat works with 24 VAC systems and
requires both R and C 24 VAC connections. This includes gas furnaces,
air handlers, electric, oil, forced air, variable speed, heat pump, and
hydronic heat.
