ClimateMaster Announces Completely New Thermostat Product Line!

OKLAHOMA CITY, July 26, 2006 - ClimateMaster has recently announced an all new commercial and residential thermostat product line for its water-source and geothermal heat pumps. The product line is designed specifically for ClimateMaster heat pumps, providing industry exclusive features.

The commercial thermostat product line includes an analog, non-mercury model, a number of manual- and auto-changeover digital models as well as three levels of programmable thermostats. The programmable thermostats are Energy Star rated and meet California Title 24 requirements.

The residential thermostat product line includes all digital, non-mercury thermostats, configured for manual-changeover, auto-changeover or programmable operation. Programmable models are Energy Star rated and meet California Title 24 requirements.

Both commercial and residential product lines include model ATP32U02, which has features designed to communicate with ClimateMaster CXM and DXM microprocessor controls. The new model is capable of "smart fault" recognition, whereby the thermostat queries the microprocessor board for the specific fault condition (e.g. condensate drain plugged). The thermostat has up to three heating stages and two cooling stages. Additional features include outputs for dehumidification (reheat option or whole house dehumidifier) and for humidification. A large (2 inch by 2 inch) dot matrix screen with blue backlighting and menu driven operation make the new ClimateMaster thermostat one of the easiest on the market to operate.
