Standard Features

Digital controls insure proper operation, providing a variety of field selectable settings for each installation. Advanced safety controls help protect the equipment.

Factory installed desuperheater (hot water generator) allows the capture of free unused heat, which is then used to heat domestic water. This application can cut hot water costs by up to 50%.

Units meet ENERGY STAR® requirements, which is often needed for eligibility of rebates and incentives.

Two-stage Copeland® UltraTech® compressor offers superior part-load performance, providing better humdity control, greater efficiency and quieter operation.

All-aluminum microchannel air coil eliminates the potential for formicary corrosion, enhancing reliability and efficiency.

Variable speed, ECM blower motor ensures quiet start up and operates at a fraction of the cost of a conventional blower motor.

Condensate overflow sensor protects against potential overflows due to clogged drains.

Insulated cabinet panels combined with compressor isolation provide superior sound/ vibration absorption. TETCO models do not use fiberglass insulation, which can create harmful contaminates and diminish indoor air quality.

TETCO units use R-410A,
a zero ozone depleting refrigerant.
